The invention further concerns the manufacture and use of such products.

Description

Products comprising an applicator and a lipid and aqueous phase

The present invention relates to puffs, pads, sponges, cotton balls, swabs, brushes, gloves, mitts or bars, to which a lipid phase and an aqueous phase are applied. It relates to products for cleansing and other uses, including the same applicator. The invention also relates to methods of making and using these products.

Many applicators have been developed for supplying materials to surfaces, and such applicators have various properties in the choice of materials, such as, for example, elastic or inelastic or recycled or disposable applicators. Such applicators are used to apply ingredients to surfaces in the form of creams, pastes, gels, liquids, powders and the like. In particular, such applicators are used to apply topical preparations, such as cosmetics and skin treatments, to the skin. The applicator is used with a separate product source or impregnated or coated with a predetermined amount of product.

One particular type of applicator is a wipe that has become an important product with a variety of uses for adults and infants. Examples include facial or body cleansing wipes, wipes for skin treatments, and skin conditioning wipes. So-called wet wipes are successful examples of particularly suitable products for these applications.

The development of wipes focused on the wipe material and the lotion applied to it, as well as the wipe itself. In addition to the basic cleansing properties of wipes, lotions have been developed that provide the benefits of skincare.

However, these attempts still leave room for improvement. First, only a small amount of lotion is released from the wipe during use. Therefore, a relatively expensive lotion cannot be supplied to a large amount of skin and discarded at the time of disposal of the product after use, which does not provide a benefit to the consumer. This also prevents the use of expensive but effective ingredients. Second, in terms of composition, there is a clear contradiction in optimizing cleansing performance and skincare benefits in one single lotion, since ingredients with good cleansing effects are generally incompatible with effective skincare ingredients.

Another important point in cleansing is the fact that many contaminants are compatible with water and are more easily removed by water based compositions, while other contaminants are compatible with lipids and are properly removed with lipid or oil based compositions. Thus, it is necessary to include water and oil based components in the applicator to effectively completely remove contaminants.

This is especially necessary for personal cleansing products, especially products used in infants and young children. Not being clean can be unpleasant and can cause diaper rash and other infection-related symptoms. The most effective way to prevent diaper rash is to wipe your skin thoroughly to remove any microorganisms that have been identified as the causative agent. Often the source of these microorganisms is fecal debris that can remain on baby's skin while wearing a diaper. However, fecal debris is composed of both water-soluble and oil-soluble materials, so a cleansing component of both water and oil based is required to completely remove fecal debris from the diaper.

U. S. Patent No. 4,987, 632 discloses a substantially dry-to-the-touch wipe article for use in cleaning contaminated surfaces with a moisture barrier covering the surface of the sheet. International Publication Nos. WO 99/13861 and US Pat. No. 6,153,208 disclose substantially dry personal cleansing articles in which the substrate comprises a plurality of layers. U. S. Patent No. 6,280, 757 relates to a dry cleansing article comprising a substrate having pores of a particular size and frequency.

Typical applicator products are based on an applicator material with one phase, but the product of the present invention has two distinctly different phases applied on or in the applicator. The two phases differ in physical properties and can be applied to various parts or parts of the applicator. This approach ensures both optimal cleansing performance and excellent skincare properties.

Summary of the Invention

The present invention relates to a product comprising an applicator other than a porous or absorbent sheet for delivering the components to the surface, in particular the skin, to which the lipid phase and the aqueous phase are applied.

Preferably, the lipid phase is solid or semisolid at ambient temperature, more preferably present on the surface or part of the surface of one or several sides of the applicator.

In particular the applicator is a three-dimensional substrate capable of delivering the components to the surface, in particular the skin of the user. Examples of such substrates are puffs, pads, sponges, bars, brushes, cotton balls, gloves, meat or cotton swabs.

The applicator can be made of various materials configured to retain and / or absorb the lipid phase and the aqueous phase. Thus, the material used in the applicator can be porous or absorbent in nature. The materials are especially natural and synthetic polymers.

In a further aspect there is provided a method of making a product described herein comprising applying the lipid phase and the aqueous phase to the applicator sequentially or simultaneously. In a preferred process, the applicator is first coated with a lipid phase and then sprayed or impregnated with an aqueous phase.

In another aspect there is provided the use of a product described herein as a cleansing article, particularly a personal hygiene application.

In a further aspect, the present invention relates to the use of an article described herein as an applicator of an active substance.

In another aspect, the present invention relates to the use of an article described herein as an applicator and formulated cleanser of an active substance.

In the product according to the invention the applicator may be elastic or inelastic. The applicator can be used as is or have an appropriate handle and can take a three-dimensional form suitable for application to a plane including the skin. The applicator can have different sizes and various shapes, for example, rounded shapes including flat, geometric, cylindrical, oval, spherical and the like, angled shapes such as square or rectangular, including cubes or rods with rounded corners, Or combinations thereof. One or more outer sides of the applicator may be made of different materials with different properties. For example, one side may be smooth while the other side may be rough. The rough side can be used to rub with wear. The applicator is rigid, ductile, semi-soft, elastic or inelastic and can be squeezed or absent.

One embodiment is a puff, pad, brush, glove, meat, cotton swab or cotton ball.

Another embodiment is a sponge. The sponge comprises the sponge itself, foams and felts composed of synthetic and / or natural materials.

Another embodiment is a bar.

The handle can be fitted to the applicator for ease of use. The applicator of this aspect preferably has an elastic pad, puff or sponge portion and a finger grip portion. One type of such applicator generally has a T-shaped shape. Examples of such applicators include elastic discs with small straight handles.

The applicator may be made of a material capable of retaining, adsorbing or absorbing the lipid phase and the aqueous phase. Preferably, the applicator material consists of substantially porous or absorbent material, which may be due to the chemical structure of the applicator material or its physical arrangement or both. Examples of specific physical arrangements are porous structures, or cellular or microcellular structures.

The applicator can be made of one material or different materials, and the materials are arranged in different ways depending on the applicator. Small portions of one or more materials of the same or different size may be inserted into a matrix of the same or different material. Alternatively, the applicator may have a multilayer structure, such as stacked layers or concentric layers, or may be made of one kind of material. The applicator parts can be connected together by gluing, sewing, stitching, or other techniques known in the art, which were of different materials.

In one embodiment, the applicator comprises a core partially or completely wrapped in laminated material. The wrapping material may be the same or different from the material (s) used for the core.

The materials that make up the applicator are especially natural or synthetic polymers. One or more crosslinkable polymeric materials may be present. Optionally, other nonpolymerizable materials may also be present, such as binders, fillers, dyes, and the like.

The material may be somewhat inert or degradable, in particular biodegradable. The material can be disposed of in the toilet. As used herein, "disposable to the toilet" means that the material passes through a drain pipe of at least 3 meters by flushing two toilets.

Examples of polymeric materials used in the applicator include synthetic polymers such as polyethylene, polypropylene, PET, polyamide, polyvinyl alcohol, polyurethane, and the like, and polymers of natural or natural origin, such as cellulose, wood pulp, and the like, and synthetic and natural fibers or There is a mixture of materials.

The applicator, when in the form of puffs (poufs), may consist of spongy or resinous foam material optionally wrapped with a suitable monolayer or multilayer material, which may be made of a closed or perforated material layer or membrane. . In another embodiment, the puff is made of one or more layers of material that can be bonded or glued together in the core of the puff.

The applicator, when in bar form, may consist of a lipid phase material in the solid state which is optionally mixed with other components. Preferably, this embodiment is wrapped with a suitable laminate material capable of containing an aqueous phase or wax dispersion, while the other phase is held in the core as a reservoir inside the bar.

The bar may be in a perforated form with a small cavity capable of containing certain components including the aqueous phase, where the aqueous phase is thereby trapped in the bar.

The bar shaped applicator may be designed such that the bar, in use, slowly degrades or dissolves, for example, by body temperature or other external factors. In particular, the bar may consist of a solid lipid phase material which, during use, decomposes or dissolves, for example, by body temperature.

When using laminated materials, these materials themselves can be single or multi-layer fabrics or nonwovens. They can be made of one or more materials. Particularly preferred laminate materials are those in which the fibers or filaments are randomly distributed (made by an air-laying or a specific wet-laying process) or have a network structure of fibers or filaments having a constant orientation (made by other wet-laying or carding processes). It is made of nonwoven fabric. The fibers or filaments can be natural materials (eg wood pulp, wool, cotton, linen, etc.) or synthetic materials (eg polyvinyl, polyester, polyolefins, polyamides, etc.).

One form of nonwoven material is a paper based material made primarily of cellulose based fibers. The binder material may be added if a high wet strength or a rigid nonwoven web is desired. Additives can be added to increase the softness. In other types of nonwovens, the web consists mainly of raw fibers based on, for example, cotton, wool, linen and the like.

Generally, the nonwoven materials used in the applicators of the present invention are made of synthetic fibers such as cellulose fibers, polyester or polypropylene, or mixtures thereof. So-called spunlace or hydro-entanglement techniques can be used to obtain high strength webs containing no binder material.

One type of nonwoven material is made from a mixture of pulp and raw fibers, and may or may not use binder materials (especially those mentioned above). If no binder material is used, the nonwoven is preferably produced by a hydro-entangle process.

2 awards

In the process according to the invention, the applicator material is in contact with the lipid phase and the aqueous phase. In some cases the applicator is contacted with a third phase, which may be a polymer phase.

The phase may be applied throughout the applicator (ie, applied continuously) or applied to a portion of the applicator (ie applied discontinuously). One phase may be applied continuously and the other may be applied discontinuously. The phase may be applied to the surface or inside of the applicator. When applied to a surface, one or both phases may be present on one or several sides of the applicator, or one phase may be present on one side of the applicator and the other phase may be present on another side.

One or both phases are present in certain regions of the applicator, in particular in one or more regions when applied discontinuously. In this case, the phase (s) may be present in one or more shapes or shapes. For example, they may be dots or spots, lines or stripes, or geometric shapes such as squares, rectangles, circles, or the like, or symbols such as letters, text, logos, numbers, or the like, or trademark marks or other shapes, or a combination thereof. . The shape or shape may be present throughout the applicator or clustered in one or more regions (eg, corners).

In certain embodiments, one phase is applied to one or several sides of the applicator in a stripe, dot or other shape, which shape covers all or part of the surface of the applicator. The aqueous phase is applied to the entire surface or a specific area of the applicator. The aqueous phase is preferably applied in the second step after the lipid phase is applied, and may be applied simultaneously in a one step process.

In a preferred embodiment, the two phases are applied to the applicator sequentially, with the application of the lipid phase first followed by the aqueous phase.

Different portions of the applicator may contain different aqueous phases and / or lipid phases. For example, the applicator may contain a lipid phase on one side and another lipid phase on the other side. In other embodiments, the applicator may contain a lipid phase on one side and an aqueous phase on the other side.

The applicator may consist of two or more parts linked together, each part being treated with a different lipid phase. Thus, for example, an applicator having cleansing performance in one part and care performance in another part can be obtained.

The applicator may be coated with a lipid phase (preferably solid) when in the form of a puff, pad or sponge. Alternatively, the puff may have a lipid phase, which may be a liquid, semi-liquid or solid, receding inside the applicator. The lipid phase may be distributed uniformly (meaning it is distributed somewhat equally throughout the interior) or non-uniformly when receded inside.

If the applicator is in the form of a bar or sponge, it can be wrapped with a sheet material and a lipid phase can be applied to the sheet material. The bar or sponge material itself may also contain the same or different lipid phase (s). It is preferred that the outer lipid phase is a solid and the inner lipid phase is a solid, semisolid or liquid. The lipid phase may be deposited on the inner portion of the applicator or the applicator may be solidified after impregnation with the lipid phase material in liquid form. This type of applicator further contains an aqueous phase which may be present in or on the surface layer.

If the applicator is in puff form, the lipid phase can be applied in powder form.

The applicator may be in the form of a perforated with multiple cavities that may contain an aqueous phase when in the form of a bar.

The applicator may be made of a degradable material such as a biodegradable material when in the form of a sponge. For example, it may be made of soluble cellulose, which may be mixed with the lipid phase when the cellulose is in the liquid state in the manufacturing process.

Geological phase

The lipid phase applied to the applicator is formulated to be or is insoluble or essentially insoluble in the aqueous phase. However, in some cases the two phases may be mixed or dissolved with each other to a limited extent. The lipid phase and the aqueous phase should or should not be formed to form one or continuous phase on the sheet before the user uses the sheet product.

The lipid phase is hydrophobic and generally consists of a water insoluble material such as oil or fat or wax. The lipid phase may be liquid, semisolid or solid at ambient temperature. The lipid phase can be semisolid, and semisolid has the standard meaning used in the art. The lipid phase may be amorphous, semicrystalline or crystalline, or may take the form of a cream or waxy composition.

Semi-solids may appear when the lipid phase is in the transition phase between the solid and liquid states, such as in the melting process, and may be due to the increased viscosity of the materials making up the lipid phase. Semisolids are present in waxes, creams, pastes, gels or similar materials with hardness. In particular, semisolids appear in materials that do not have a distinct melting point, ie, materials with melting ranges. This is also seen in materials having properties similar to glass, for example polymers in a glassy state.

In particular the lipid phase has a melting point or melting range above room temperature, in particular above 25 ° C., for example 25 to 100 ° C., in particular 30 to 75 ° C., more specifically 30 to 45 ° C., preferably 32 to 40 ° C. More preferably the melting temperature or melting range is above the human body temperature. Most preferably the melting temperature or melting range is approximately equal to or equal to the human body temperature.

In some embodiments of the invention the lipid phase may have a relatively high melting point or melting range. The melting point or melting range is, for example, higher than body temperature and may be, for example, above 40 ° C or above 45 ° C. In the use of such applicators, stronger interaction between the two phases may be required, or higher temperatures may need to be applied to facilitate the interaction. In the latter case, consumers may need to use the product, for example after first contacting it with warm water. In the former case the aqueous phase may contain components which enhance the interaction with the lipid phase more strongly.

As used herein, "melting range" refers to the temperature range from the temperature at which the material or composition loses its solid state until it is completely liquid. When the melting range overlaps with the prescribed temperature range, it is considered to be within the prescribed temperature range, and when the melting range is higher than a specific temperature, it is regarded as exceeding the temperature.

As used herein, "ambient temperature" means in the range of about 20 to about 25 ° C.

The lipid phase may change to another state after being applied to the applicator, or during application to the applicator during storage, or when used by the consumer. The lipid phase is applied to the applicator as a liquid, which can then be semisolid or solid. Alternatively, the lipid phase can be semisolid or liquid during consumer use. This change in state can be induced by physical factors such as temperature or pressure, but can also be induced by chemical factors such as certain components that give rise to polymerization or photochemical reactions.

In certain embodiments, the lipid phases can be applied as two separate phases, which are mixed while being applied onto the applicator, where certain components within each phase begin to mix and interact (e.g. polymerization) with the state of the lipid phase Changes from liquid to semisolid or solid.

Particular preference is given to compositions on lipids which are solid at room temperature and have a permeation value of 0.2 to 4 mm (measure: Petrotester PNR 10, Mikrokonus, 5 sec, temperature 20 ° C.).

The water content of the lipid phase is especially low, less than 10%, preferably less than 6%, more preferably less than 3%. In certain embodiments, the lipid phase is water free and will not be degraded by the aqueous phase. By "water free" is meant herein a phase composed of a material having a low water content, to which no water is added.

The lipid phase may comprise one or more components selected from oils or fats or waxes. It may also contain other ingredients. As used herein, oil or fat refers to the same kind of material, where oil is liquid at ambient temperature and fat is solid or semisolid at ambient temperature. The lipid phase may also comprise a mixture of waxes and fats and / or oils.

In a preferred embodiment, the lipid phase is a wax based composition, where "wax" is as described below.

In certain embodiments, a plurality of lipid phases having different compositions may be applied to the applicator. For example, one type of lipid phase is applied to one side of the applicator and another type of lipid phase is applied to the other side. Each lipid phase may contain one or more components described below, for example one or more components selected from active ingredients, dyes, emulsifiers and other components described below. Multicolored patterns can be obtained when different dyes are contained (eg each lipid phase has a different color or is colorless).

Different lipid phases may be applied to each side of the applicator in different ways. For example, one side applies the lipid phase completely and the other side is applied in the form of a pattern (eg, a stripe).

Oils and fats

The lipid phase may contain oils, fats, or mixtures of fats with oils and / or oily ingredients. The mixture constituting the lipid phase is preferably selected such that the melting point or melting range of the lipid phase is as mentioned above, in particular above ambient temperature and more specifically between 32 ° C and 40 ° C.

Additional ingredients

The composition on the lipid may contain additional ingredients that may have similar or other properties as the wax. The use of these additional components not only improves the feel properties but also improves the stability of the composition after application to the applicator material, especially when in contact with the aqueous phase. Other ingredients may also be added to improve hardness, feel and appearance. These components are generally insoluble in water or will not dissolve well. The water soluble component may typically be added with a solubilizer or emulsifier and some water.

Examples of additional ingredients include superfatting ingredients, thickeners, polymers, active ingredients, film formers, UV-filters, antioxidants, combustibles, preservatives, repellents, self-tanning agents, solubilizers, perfume oils, dyes, and the like. have.

These additional components may be present in the lipid phase in an amount ranging from 0 to 30%, in particular from 0.1 to 20%, in particular from 1 to 15%, more specifically from 5 to 10%.

Substances which can be used as the superpating component include, for example, lanolin or lanolin derivatives such as lanolin alcohols, lanolin acids, polyethoxylated or acylated lanolin or other lanolin derivatives; Phospholipids such as lecithin or lecithin derivatives (eg, polyethoxylated or acylated lecithin or other lecithin derivatives); Polyol fatty acid esters, monoglycerides and fatty acid alkanolamides.

Suitable cationic polymers are, for example, cationic cellulose derivatives, for example copolymers of quaternized hydroxyethyl cellulose (trade name Polymer JR 400 ^R , manufactured by Amerchol), cationic starch, diallyl ammonium salts and acrylamides. , Quaternized vinylpyrrolidone / vinylimidazole-polymers (e.g. Luviquat ^R , manufactured by BASF), concentrated products of polyglycols and amines, quaternized collagen polypeptides, such as lauryldimonium hydroxypropyl hydrolysis Collagen (Lumequat ^R L / Guenau), quaternized wheat polypeptide, polyethylene imine, cationic silicone polymers such as amodimethicone, adipic acid and copolymers of dimethylaminohydroxypropyldiethylenetriamine (Cartaretine ^R / Sandoz), a copolymer of acrylic acid and dimethyldiallylammonium chloride (Merquat ^R 550 / Chemviron), polyaminopolyamides, cationic chitin derivatives such as quaternized chitosan, dihalogenalkylene such as dibromobutane and bis-dimethylamino-1, optionally dispersed in microcrystalline form, Concentrated products obtained from bis-dialkylamines such as 3-propane, cationic guar gum derivatives (e.g. Jaguar ^R CBS, Jaguar ^R C-17, Jaguar ^R C-16, manufactured by Celanese), quaternized ammonium salt-polymers (E.g.

The lipid phase may be a suitable antioxidant such as sulfite (e.g. sodium sulfite), tocopherol or derivatives thereof, ascorbic acid or derivatives thereof, citric acid, propyl gallate, chitosan glycolate, cysteine, N-acetyl cysteine and zinc sulfate, Thiosulfate (such as sodium thiosulfate), polyphenols, and the like.

The lipid phase may be a powdered or powdered component such as talc, bolus alba, myristyl alcohol, cetyl alcohol, cetylstearyl alcohol, calcium or magnesium stearate, magnesium lauryl sulfate, starch or derivatives thereof or mixtures thereof. It may further contain.

The lipid phase may also contain a disintegrant, which is a substance that causes the breakdown of the physical integration of the lipid phase. Disintegration can occur in part or in whole on the lipid. Disintegrants may be mixed or dissolved in some or all of the lipid phase. Disintegrants can be mixed continuously in the lipid phase, or discontinuously mixed, for example, on the top side of the lipid phase (eg, in the top side of the layer or in the top portion of the layer if the lipid phase is applied as a layer). have.

Suitable disintegrants are components that undergo physical or chemical interactions by self-interaction or interaction between two materials. This causes a physical or chemical interaction with the lipid phase. One type of disintegrant is the release of gas by decomposition or chemical reaction between two components. Examples of disintegrants are solid mixtures of bicarbonates with acids such as sodium bicarbonate or potassium bicarbonate and suitable organic acids such as citric acid. Upon contact with water, for example, upon contact with the aqueous phase, the disintegrant components interact to liberate carbon dioxide, thereby physically changing the lipid phase. This physical change can cause the lipid phase to be evenly distributed in the applicator. This has a positive effect on the interaction between the aqueous phase and the lipid phase, which in turn has a positive effect on the delivery of, for example, the ingredients in these phases (eg the active ingredient) to the skin.

The lipid phase may also contain components that undergo a polymerization reaction during or after application to the applicator material. Examples of such components are oligomers which continue to polymerize with monomers or other oligomers during or after being applied to the sheet. Another example is a component that causes netting or copolymerization. There may also be agents that inhibit polymerization for a certain time. There are also components which promote polymerization under the influence of external factors such as, for example, heat, light or pressure.

In one embodiment, the lipid phase contains monomers or oligomers that can be polymerized or copolymerized under the influence of external factors such as light. Light is irradiated onto the lipid phase during the process of applying the lipid phase to the applicator (polymerization takes place at this time). Alternatively, light may be irradiated after applying the lipid phase to the applicator.

The lipid phase may also contain dyes that change color due to changes in temperature or pressure when using the product. This will allow the consumer to feel and trust that the product supplies the skin with a lipid phase (or the active ingredient if the lipid phase contains the active ingredient).

The lipid phase may also contain dye-precursors, ie components which are dyed under the influence of physical or chemical factors. In certain embodiments, the lipid phase may contain dye-precursors that react with certain components present in the aqueous phase to form dyes. Likewise, dye-precursors may be converted to dyes when interacting with certain chemicals incorporated in the lipid phase while present in the aqueous phase.

The lipid phase may be formulated with beads. Particular forms of beads are polymer beads in which the lipid phase is trapped therein in any form. The term "bead" or "polymer bead" encompasses freely flowing discrete powder, bead or capsule forms that wrap, coat or contain a lipid phase within a mono- or polymeric matrix or capsule. These terms also encompass powders, beads or capsules in which the mono- or polymer matrix itself is in the lipid phase. These terms also include porous beads or "fine sponges" and "fine capsules", the latter being beads of smaller size. The beads may be coated with a suitable coating material that protects the interior of the beads or controls the release of lipid phases entrapped therein. The coating itself on the beads may contain a lipid phase. In this case, the coating may be applied on an inert core or on a core containing lipid phase and / or other ingredients.

Formulating the lipid phase into beads may be to protect the lipid phase from external factors that may affect the integration of the lipid phase. However, most of them are for controlled release on lipids.

Certain types of beads are small beads or capsules having an average diameter in the μm range and the average diameter may be as small as 200 nm.

Capsules of this type can be, for example, liposome based capsules made of phospholipids such as lecithin, phosphatidyl ethanolamine, phosphatidyl serine, phosphatidic acid and the like. Capsules of this type can also be made from starch, cellulose, porous gelatin and the like.

Capsules or beads may be relatively large in average size in the range of mm or 0.1 mm. Capsules or beads of this type may be made from agar, glycolic acid polymers, and additional ingredients such as water, mineral oils, glycerin. They may contain additional ingredients such as preservatives, dye (s) and the like.

Another form of beads or microcapsules is a microsponge. These are materials of about 5 to about 300 micrometers (average diameter) in size with a wide inner surface. These are obtained by polymerizing specific monomers. The lipid phase material is trapped inside during or after this polymerization process. Fine sponge-based carriers can be used to protect the lipid phase trapped therein or for controlled release.

The capsule may optionally contain one or more suitable disintegrants, in particular the disintegrants mentioned herein. Upon contact with a suitable external factor, the disintegrant will open the capsule and release the lipid phase trapped therein.

Capsules may be incorporated in the aqueous phase or other lipid phases or both. These may be applied to the applicator prior to introducing the lipid phase and the aqueous phase, or may be introduced during the manufacturing process of the applicator itself.

Rupture of the coating from the matrix can result in release of the lipid phase from the beads or capsules. This can occur due to physical factors such as pressure, deformation or shear forces that occur when using the applicator product, for example when rubbing the product on the skin or surface. The release of the lipid phase may be due to the nature of the semipermeable or porous nature of the beads or their coatings, due to external factors such as contact with the liquid medium which extracts the lipid phase or dissolves or disintegrates the beads or their coatings, or to the influence of temperature. It may be due to. Capsules may also be collapsed under the influence of certain chemicals, especially disintegrants incorporated into the capsule. A particular aspect of this is a capsule containing a suitable amount of bicarbonates and organic acids that break down the capsule when contacted with water in use of the applicator product, for example when contacted with an aqueous phase.

Beads or capsules may be prepared according to techniques generally known in the art, such as emulsion polymerization methods.

The beads or capsules may be applied to any part of the applicator, but are preferably concentrated on the surface or the top surface portion of the applicator. The lipid phase can then be maximized on the skin or surface where the product is used.

Beads or capsules may be applied to the applicator in dry form by methods such as dusting, sieving, spraying, and the like. They may be printed or roll-coated in the form of a suitable liquid or paste. They may be sprayed into the applicator in admixture with a suitable liquid which may be a bead or a solvent inert to the water or aqueous phase.

Geological application

The lipid phase is applied to the applicator in various ways. The lipid phase is preferably applied to a surface or a portion of the surface of one or several sides of the applicator.

The lipid phase may be applied evenly or unevenly to the applicator, wherein unevenly applied means that the distribution of the lipid phase differs over the area of the applicator, that is, some area of the applicator will have more or less amount of lipid phase. Can be. The lipid phase is preferably applied evenly over the area of the applicator.

The lipid phase may be applied discontinuously or continuously on one or several sides of the applicator, or may be applied to completely cover one or both surfaces of the applicator.

The lipid phase is preferably applied in a discontinuous pattern on one or several sides of the applicator. For this purpose, the lipid phase is applied to a specific area of the applicator in a predetermined controlled manner. A discontinuous pattern is a pattern in which the lipid phase is applied to specific areas spaced apart by areas of the applicator without the lipid phase. In this case, the lipid phase is applied to a defined portion or area of the applicator, which can take various forms. The lipid phase may be applied as described more generally, particularly for the application of two phases. Specific application forms of the lipid phase can be, for example, stripes, dots or spots, regular or irregularly shaped geometric shapes, eg, circular, oval, square, rectangular, etc., logos, text, letters, or geological phases and aqueous phases. Other discontinuous patterns, including the pattern described above for application of the image more generally.

Discontinuous patterns also inherently include larger reticular patterns on lipids. In a preferred embodiment, the lipid phase is present as discrete stripes that can be disposed discontinuously (ie interrupted in the middle) or preferably placed continuously throughout the surface of the applicator. Stripes may form a pattern of separate compartments (they come together to form a stripe) or may have a repeating pattern, such as a pattern such as a sinusoidal curve or wave pattern. If a fringe is selected, the stripes are preferably in the phase so that the stripes remain in equilibrium and each stripe is spaced from the adjacent stripes.

The stripes are preferably oriented in the machine direction for ease of manufacture.

In certain embodiments, one or more lipid phases may be applied to one or several sides of the applicator. For example, one lipid phase may be applied to the entire surface or a portion of the surface of one side of the applicator, and a lipid phase that is different in whole or only to the other side may be applied in the same or different pattern as the pattern of the other side. have. In this particular embodiment, two different lipid phases on the same side are present in parallel stripes or other patterns of the same or different colors.

In certain embodiments up to half of the surface is applied onto the lipid on one or preferably several sides of the applicator. In a preferred embodiment, the lipid phase is present on the surface of various sides of the applicator and covers up to 50%, in particular up to 35%, or up to 25% of the surface. In a particularly preferred embodiment, the lipid phase is present as streaks covering up to 1/2, in particular up to 25% of the surface, in particular parallel streaks that are distributed parallel to the side of the applicator. In other particularly preferred embodiments, the lipid phase is present as dots that are evenly spread throughout the surface of the applicator, covering up to one half of the surface.

Some aspects have dots of somewhat regular shape, others have circular dots, another aspects have ellipses, and other aspects have a mixed pattern, for example a combination of circles and ellipses, dots of regular shapes And a combination of circles and the like.

In the case of stripes, the width is preferably 1 to 10 mm, more preferably 3 to 7 mm. In the case of dots, dots of a round shape, for example, circular or elliptical, having an average diameter of 1 to 10 mm, more preferably 3 to 7 mm, are preferable. There can be stripes with different widths in one article, and dots with different sizes can exist in one article. An example of the latter is an applicator having a specific size of a circle and a different size of an oval, or a different size of a circle.

The lipid phase may be colorless, monochromatic or multicolored. Multicolored patterns are obtained by applying a plurality of lipid phases with different colors. By using the colored lipid phase, the user may feel that the applicator is covered with a special material containing the active ingredient and may make the product look aesthetically more beautiful.

In other embodiments, the applicator itself is colored over all or part of the surface in various aspects or on one side. If color is present only in a portion of the applicator, it is desirable to take the shape and pattern described for the pattern on the lipid. In other embodiments only the space between the surface portions to which the lipid phase has been applied is colored and the area of the lipid phase remains uncolored. In this method the pattern on the lipid will appear as an uncolored pattern.

A preferred pattern for coloring the applicator is stripes. An example of such an embodiment is a pattern in which the colored stripes are covered with a lipid phase or the area between the colored stripes is covered with a lipid phase. In the former case, the lipid stripe is colored. In the latter case, the lipid stripe is not colored.

Lipid phases, which can be colored or colorless, can be applied to the colored applicator in various ways. In the case of an applicator with a fully colored surface, the lipid phase can be applied throughout the surface to obtain different or changed colors (eg lighter color if the lipid phase is white or opaque). In addition, by applying the lipid phase in a specific pattern, a product having various colors can be obtained, or a product having a solid pattern when the lipid phase is white or opaque. Also in this case, a preferable pattern is stripes.

In further embodiments, the applicator is colored in a particular pattern and a lipid phase is applied over or over a portion of these patterns. Even in this case the lipid phase may be colored or colorless, ie white, opaque or transparent. If the lipid phase is white or opaque, its thickness can be selected so that the color of the bottom of the applicator is visible so that the consumer feels that a lipid phase containing a particular component is present.

The lipid phase is applied to one side, preferably several sides, of the applicator typically in an amount of about 3 to about 40 g / m 2, preferably about 10 to about 20 g / m 2. Alternatively, the lipid phase is applied in an amount of about 0.06g to about 0.8g per gram of substrate, preferably from about 0.20g to about 0.40g per gram of dry substrate.

The lipid phase can be applied to the applicator in a manner used to contact or impregnate the liquid or molten liquid material into the applicator. The applicator may be bathed in the liquid lipid phase to apply the lipid phase. If the lipid phase is solid or semisolid at room temperature, it is liquefied by melting or dissolving in a suitable solvent, and the solvent is then evaporated.

The lipid phase may also be applied using a method of coating the lipid material on the surface of the applicator. As used herein, the term "coating" means printing, covering, overlaying, finishing, spraying, extrusion, lamination, or other method of applying an image to the surface of an applicator.

A particular coating technique is the extrusion method, where the composition is pushed through the tube and brought into contact with the applicator while passing through the tube. Preferred techniques include contacting the applicator with a heated head equipped with a slit blade (ie, a blade with a cutting area, from which the molten lipid phase is extruded). Another preferred coating technique includes a so-called hot melting process comprising spraying a liquefied lipid phase from a heated spray head or nozzle. Another application technique involves spraying or dropping the composition onto a rotating surface, such as a calender roll, and then transferring the composition to the surface of the substrate.

Another technique is based on typical printing techniques such as screen printing, roller printing and gravure printing, for example. Generally, printing techniques provide ridges on the rotating surface (by typesetting, embossing, or similar techniques), contact the ridges with the liquefied lipid phase (eg, disperse the ridges through a bath of liquefied lipid phases). Printing on the applicator. Another application technique of lipid phase uses a screen printing method in which molten lipid phase is introduced into a rotating roll and then pressed through a metal screen covering the roll. This provides the applicator with a defined pattern, such as stripes, dots, squares, circles, etc., or logos and text, depending on the shape of the screen.

A further technique of applying the lipid phase to the applicator is a roller-ball application method comprising contacting a ball in direct contact with the applicator with a lipid phase in the liquid state and moving it through a rotational movement over the applicator. Depending on the desired pattern on the lipid on the applicator, there may be several roller-ball applicators raised sideways or back. They may contain the same or different lipid phases.

The lipid phase can also be applied by high pressure coating. In the method of this embodiment, the lipid phase is applied by extrusion through a suitable nozzle under high pressure. Particularly shaped nozzles can be used to obtain specific patterns. For example, there may be a nozzle providing a pattern of circular, star, square or other geometric or irregular shapes.

These application techniques may be combined to apply the lipid phase.

The lipid phase may be applied to the applicator as a particle or powder. In this embodiment, the lipid phase is applied as beads or small capsules by dropping or screen printing or the like. After application, the particles can be melted to form small dots in or on the applicator.

The lipid phase is preferably applied in liquid form, for example in molten form, and may be applied as a powder.

The lipid phase can be applied in the form of a liquid mixed with colored or uncolored water and then the water can be removed to obtain a dry or essentially dry product. "Liquid form" here refers to a form in which the lipid phase is originally liquid or liquefied by heating, for example by heating in the water to be applied. The lipid phase is maintained as a liquid throughout the process. In the case of solid lipid phases, the added water is allowed to solidify after removal. In one embodiment the lipid phase is mixed with hot water and then the lipid / water mixture is applied to the applicator. The water is then evaporated by various means, such as simply allowing the water to evaporate, forcing the applicator through one or more heated elements, forcing the water to evaporate, or using heated or unheated dry air. Or evaporated under reduced pressure.

If colored water is used, the water diffuses into the applicator and after evaporation the applicator is colored. The lipid phase applied in this embodiment may be colorless, in which case it will appear as a white or lighter area. Alternatively, the lipid phase can be colored, in which case a product with different colors will be obtained. In another embodiment, the colored lipid phase and the uncolored water are used in the process to obtain a product where the regions of the lipid phase are colored and the other regions are not colored. The product thus obtained is then treated with a colored or uncolored aqueous phase to give a product with a more colorful color combination.

In one embodiment, the lipid phase is applied continuously or discontinuously as a layer on one or several sides of the applicator, and pressure is applied to the surface of the lipid layer to form dots. The material of the dots may be the same or different from the material of the lipid layer.

The lipid phase is preferably applied in such a way that it remains on the applicator surface during manufacture and storage. This is typically accomplished by applying the lipid phase at a temperature above its melting temperature (eg, spraying or coating the surface of the applicator when the lipid phase is molten) and then cooling below its melting point to solidify the lipid phase. can do.

It is desirable to apply the lipid phase to the surface of the applicator, in which case its physical location makes it easier to apply it to the skin when in use. As a result, the effectiveness, efficacy, and performance of the incorporated active ingredient are improved when the lipid phase is delivered to the skin in use, as compared to products that are simply incorporated into a single phase to which the active agent is applied continuously.

In a preferred embodiment, the melting point or melting range of the lipid phase is above 25 ° C. or has the temperature range described above, whereby the lipid phase can be applied to the applicator in a liquid (melt) state, and then after cooling the lipid phase is in a solid state to the applicator. Because it exists. This makes the step of post-treatment of the applicator to which the lipid phase has been applied with the aqueous phase more convenient and easier. In this way the two phases are applied in such a way that they do not mix or interact. In a more preferred embodiment, the lipid phase is applied to form a fragile film that is not broken on the applicator. Applicators treated in this way are particularly stable during storage because the two phases are essentially incompatible. In addition, such applicators will melt when the lipid phase is in contact with the skin, causing the two phases to be locally mixed or emulsified.

In some embodiments of the present invention, the product may contain two or more lipid phases with different stability to the aqueous phase. This allows one phase to interact with the aqueous phase more quickly than the other. It can be used in products which require gradual release of the active ingredient or sequential release of two or more active ingredients.

Aqueous phase

The aqueous phase can be an aqueous based composition known in the art used to impregnate the applicator. The aqueous phase may contain, in addition to water, additional ingredients or additives such as surfactants, emulsifiers, thickeners, conditioners, humectants, thickeners, preservatives, active ingredients, in particular cosmetic or dermatologically active ingredients, perfumes and the like. Particular preference is given to active ingredients suitable for topical application.

The aqueous phase may contain suitable dyes which are preferably hydrophilic. In one embodiment, the lipid phase is applied discontinuously as a layer in the form of stripes, for example leaving a colored area with only the aqueous phase. This makes it possible to produce applicator products having colored patterns (eg colored lines) or even multicolored patterns when the lipid phase itself is colored.

The aqueous phase may also contain a lipophilic dye that, when in contact with the lipid phase, migrates into and becomes colored in the lipid phase.

The aqueous phase is, for example, alkali metal salts such as phenoxyethanol, C _1-4 alkylparabens and salts thereof, in particular sodium salts such as C _1-6 alkyl such as methyl, ethyl, propyl, isopropyl, butyl parabens and the like. Parabens), chlorohexidine, formaldehyde or formaldehyde release agent, benzyl alcohol, chloroxylinol, phenoxyethanol, methylchloroisothiazolinone, methylisothiazolinone, sodium benzoate, chlorohexidine di Gluconate Methyldibromo Glutaronitrile, Sodium Borate, 5-Bromo-5-nitro-1,3-dioxane, Alcohol, Benzoic Acid, Dehydroacetic Acid, Diazolidinyl Urea, Dichlorobenzyl Alcohol, Glucose Oxide Azees, hexamidine diethionate, imidazolidinyl urea, iodopropynyl butylcarbamate, isobutylparaben, isopropylparaben, lactoperoxidase, magnesium nitrate, PEG-4 laurate It may also contain one or more preservatives such as phenethyl alcohol, polyaminopropyl biguanide, potassium sorbate, propylene glycol, pyridoxine HCl, quaternium-15, sorbic acid, triclosan, tocopherol and the like.

The aqueous phase may contain suitable surfactants in limited amounts, preferably less than 20%, or less than 15%, or less than 10%, in particular less than 5%, or less than 3% by weight of the aqueous phase. Examples of surfactants that can be used are:

Alkyl sulfates such as sodium lauryl sulfate, ammonium lauryl sulfate, sodium cetearyl sulfate;

Alkyl sulfoacetates such as sodium lauryl sulfoacetate;

Alkyl ether sulfates such as sodium laureth sulfate, sodium trideset sulfate, sodium oleate sulfate, ammonium laureth sulfate;

Alkyl ether sulfosuccinates such as disodium lauret sulfosuccinate;

Alkyl glycosides such as decyl glucoside, lauryl glucoside;

Alkyl isothionates;

Amphoteric substances such as cocamidopropyl betaine, sodium coco ampoacetate, sodium lauro ampoacetate, disodium lauro ampodiacetate, disodium coco ampodiacetate, sodium lauro ampopropionate, tooth Sodium lauroampodipropionate, potassium or ammonium salts of the amphoteric substances described above, capryl / capricamidopropyl betaine, undecyleneamidopropyl betaine, lauamidopropyl betaine and fatty alcohol poly Glycol ethers.

Suitable conditioners include, for example, alkylamido ammonium lactate, cetyl dimethicone, cetyl ricinolate, dimethicone, laureth-23, laureth-4, polydecene, retinyl palmitate, and glyceryl monools Materials selected from latex, cocoglucoside and mixtures thereof (especially 'Lamesoft ^R ' from Cognis, a mixture of these two components), quaternized protein hydrolysates, quaternized cellulose and starch derivatives, acrylic acid or methacrylic acid or Quaternized copolymers of salts, quaternized silicone derivatives, silicone oils, cyclomethicones and mixtures thereof.

The aqueous phase may also contain suitable thickeners and film forming materials.

The aqueous phase may contain pH sensitive ingredients, ie ingredients that change properties when the pH changes. The change in pH occurs when the applicator product is in contact with the skin, and generally varies from approximately pH 7, the pH of the product, to approximately pH 5.5, the pH of the skin. pH sensitive components include, for example, certain emulsifiers, stabilizers, surfactants, viscosity modifiers, chelating agents, and the like.

In one embodiment, a suitable emulsifier is pH sensitive within the pH range such that the pH changes, preferably enhances, its emulsification performance, resulting in an emulsification process upon contact with the skin resulting in interaction of the aqueous and lipid phases. We choose to be.

The above-described change in pH that occurs when the product is applied to the skin may promote the release of the active ingredient, in particular the active ingredient which is pH sensitive, for example the solubility of the active ingredient depending on the pH.

Application of the aqueous phase

The aqueous phase can be applied to the applicator using methods commonly known in the art for applying aqueous liquid lotions, such as spraying, dropping, impregnation and the like. Preferred application methods for the aqueous phase are spraying using a suitable nozzle or dropping using, for example, perforated tubes with holes or slits. Impregnation techniques can be performed by dispersing the applicator through a bath containing an aqueous phase and then adjusting the amount of liquid absorbed by compression.

The aqueous phase may be applied continuously or discontinuously, evenly or unevenly, over the surface or a portion of the applicator material, or preferably throughout, in various ways as described for the lipid phase. Optionally, some portions of the applicator may be left dry (ie, have no lipid phase and aqueous phase), or some portions may have lipid phase or aqueous phase. The aqueous phase can be applied to several sides of the applicator or to only one side.

The aqueous phase is typically from about 1.0g to 10g, preferably from 2.0g to 5g, more preferably from 2g to 4.5g per gram of dry substrate, most preferably from about 3.7g per gram of substrate To about 3.8 g.

It may be advantageous to apply the aqueous phase only to the regions (or sides) of the applicator that are not yet covered with the lipid phase.

In many cases, because the product is used as a cleansing article, it is advantageous to design the aqueous phase as a cleanser. The most difficult contaminants are those that are insoluble in water and / or stick strongly to the skin. Thus, the aqueous phase is formulated to remove water insoluble materials.

Additional awards

In another embodiment of the present invention, an additional layer made of polymeric material (hereinafter referred to as polymer layer) is applied to the applicator. One or more polymer layers may be applied to the applicator. As used herein, the term 'polymer layer' refers to one or more polymer layers.

The polymer layer may be applied to one or several sides of the applicator.

The polymer layer is made of a suitable polymer such as polyethylene, polypropylene, polyester, silicone and the like and mixtures thereof. The polymer layer may also contain other materials such as fillers or dyes. In the latter case, the area of the applicator covered with the polymer layer will appear as colored area. When a plurality of polymer layers are applied, different color layers can be used to obtain patterns with different colors.

The polymer layer may be applied to the applicator in a similar manner as described for the application on lipids. For example, it may be applied continuously, ie throughout the surface of the applicator, or discontinuously, for example in the form of stripes, spots or the like. If the polymer layer does not cover the entire surface, the lipid phase may cover both the region of the applicator and the other regions covered with the polymer layer.

The lipid layer can be applied over the polymer layer to form a double layer. The polymer layer need not be completely covered with the lipid phase, that is, some may remain uncovered.

The polymer layer may also be applied to areas not covered with lipids. For example, the lipid phase can be applied as a layer in discontinuous form and the polymer phase can be applied at points where there is no lipid phase. In one particular embodiment, the lipid phase is applied as stripes and a polymer layer is placed in the region between these stripes to form a pattern in which the stripes of the lipid phase and the polymer layer are alternately present. For example, one side of the applicator can be applied in this manner and the other side can be introduced with an aqueous phase.

The polymeric layer can be semisolid so that a product having such a layer can rupture when used. The semisolid polymer layer is made of a polymer with wax, cream or similar hardness. In this case, the polymer layer may be applied as an outer coating covering one or several sides of the applicator or covering part or all of the surface. The polymer layer may also cover part or all of the lipid layer.

The lipid phase covering the polymer layer can be colored or colorless. In the former case, the polymer layer is preferably colorless or white, but may be colored. If the lipid phase is colorless, the polymer phase is preferably colored, but may be white or colorless.

The polymer phase can be applied to improve or promote the delivery of the lipid phase coated thereon to the user's skin. When using colored polymer layers or colored lipid phases or both, the appearance, disappearance or change of color occurs, respectively, when the lipid phase is transferred to the skin using an applicator product.

The polymer layer is applied to the applicator using known coating methods of the material used to make the applicator, such as a material having a polymer layer. For example, the polymer layer can be applied by techniques such as screen printing, gravure printing, roller printing, embossing, spraying, dropping, bessing and the like.

Additional ingredients for one or both phases

The lipid phase and / or aqueous phase may contain additional components that may be present in one or both phases.

Active ingredient

The lipid phase and / or aqueous phase may further contain an active ingredient for application to the skin. The lipid phase preferably contains oil-soluble or hydrophobic active agents, and the aqueous phase preferably contains water-soluble or hydrophilic active agents. However, by using suitable emulsifiers, oil-soluble or lipophilic active ingredients can be incorporated into the aqueous phase and water-soluble or hydrophilic active agents can be incorporated into the lipid phase.

Products having a lipid phase and / or an aqueous phase containing one or more active ingredients constitute a particularly preferred aspect of the invention. Preferred are embodiments in which the active ingredient is present on the lipid. The active ingredient may be present in certain combinations.

The active ingredient, which may be lipophilic or hydrophilic, may be mixed with or incorporated into a suitable carrier. These include inert substances acceptable to the skin which are known for the formulation of the active ingredient. The carrier may be a finely or coarser finely divided powder or granules. These may include components such as starch, sugars, binders, lubricants, diluents, fillers, disintegrants, granulating agents and the like. The nature of the carrier material depends on the active ingredient formulated and the type of formulation desired.

Particular carriers for incorporating the active ingredient are beads in which the active ingredient is trapped in a predetermined form. The term 'bead' or 'polymer bead' encompasses freely flowing discrete powder, bead or capsule forms that wrap, coat or contain the active ingredient in a mono- or polymeric matrix or capsule. These terms also include porous beads or "fine sponges" and "fine capsules", the latter being beads of smaller size. The beads may be coated with a suitable coating material that protects its interior and controls the release of the active ingredient entrapped therein. The coating itself on the beads may contain the active ingredient, in which case the coating may be applied on an inert core.

Formulating the active ingredient into the beads may be to protect the active agent from environmental factors, but most of it is to control the release of the active agent.

Certain types of beads are small beads or capsules with an average diameter in micrometers, and the average diameter may be as small as 200 nm.

Capsules of this type may be, for example, liposome based capsules made of phospholipids such as lecithin, phosphatidyl ethanolamine, phosphatidyl serine, phosphatidic acid and the like. Capsules of this type may be made from starch, cellulose, porous gelatin and the like.

Capsules or beads may be relatively large in average size in the range of mm or 0.1 mm. Capsules or beads of this type may be made from agar, glycolic acid polymers, and additional ingredients such as water, mineral oils, glycerin. They may contain additional ingredients such as preservatives, dye (s) and the like.

Another form of beads or microcapsules is a microsponge. These are materials of about 5 to about 300 micrometers (average diameter) in size with a wide inner surface. These are obtained by polymerizing specific monomers. The active ingredient is trapped inside during or after the polymerization process. A carrier based on a fine sponge can be used to protect the active ingredient trapped therein or to control its release.

The capsule may optionally contain one or more suitable disintegrants, in particular the disintegrants mentioned herein. When in contact with a suitable external factor, the disintegrant will open the capsule to release the active ingredient entrapped therein.

Capsules can be incorporated into the lipid phase or the aqueous phase or both. These may be applied to the applicator prior to introducing the lipid phase and the aqueous phase, or may be introduced during the manufacturing process of the applicator itself.

The coating or matrix ruptures to release the active ingredient from the beads or capsules. This can occur due to physical factors such as pressure, deformation or shear forces that occur in the use of the applicator product, for example, when the product is rubbed onto the skin or surface. The release of the active ingredient is due to the nature of the semipermeable or porous nature of the beads or their coatings, due to external factors such as contact with the liquid medium which extracts the active ingredient or dissolves or disintegrates the beads or their coatings, or the effect of temperature. It may be by. Capsules may also collapse under the influence of certain chemicals, especially disintegrants incorporated into the capsule. A particular aspect of this is a capsule containing a suitable amount of bicarbonates and organic acids that break down the capsule when contacted with water in use of the applicator product, for example when contacted with an aqueous phase.

Beads or capsules may be prepared according to techniques generally known in the art, such as emulsion polymerization methods.

The beads or capsules may be applied to any part of the applicator, but are preferably concentrated on the surface or the top surface portion of the applicator. The active ingredient can then be delivered to the maximum on the skin or surface where the product is used.

Beads or capsules may be applied to the applicator in dry form by methods such as dusting, sieving, spraying and the like. They may be printed or roll coated in the form of a suitable liquid or paste. They may be sprayed into the applicator in admixture with a suitable liquid which may be a bead or a solvent inert to the water or aqueous phase.

Particularly interesting active ingredients are those that can be used to treat skin that exhibits an inflammatory response, irritation, flushing or damage. Examples of such active agents are zinc compounds or sulfur.

A further active ingredient that can be used is one known under the trade name Generol ^™ . These include ethoxylated and unethoxylated phytosterins. Other active ingredients include antimicrobial agents and bioactive ingredients.

The active ingredient may be present in various concentrations depending on the nature of the ingredient and its use, but is generally from 0.01 to 10% (w / w), preferably from 0.1 to 7% (w / w), based on the total weight of the lipid phase and the aqueous phase. w), more preferably in an amount ranging from 1 to 5% (w / w).

Other additional ingredients

Both phases are moisturizers, lipid donor ingredients, thickeners, powders, bioactive agents, deodorants, membrane formers, UV light blockers, antioxidants, dissolution aids, preservatives, insect repellents, self tanners, solubilizers, perfumes, It may contain additional components such as dyes, pigments and the like.

Moisturizer

The lipid phase and / or aqueous phase may further contain one or more humectants. They are added to improve the feel properties as well as to control skin hydration. These humectants can enhance the penetration of the composition into the applicator.

Moisturizers typically range from 1 to 20% (w / w), preferably from 5 to 15% (w / w), more preferably from 5 to 10% (w / w) relative to the total amount of lipid phase and aqueous phase. May be present in amounts.

Suitable humectants are, for example, amino acids, pyrrolidone carboxylic acids, lactic acid and salts thereof, lactitol, urea and urea derivatives, uric acid, glucosamine, creatinine, hydrolysis products of collagen, chitosan or chitosan salts / derivatives, and especially Polyols and polyol derivatives such as ethylene glycol, propylene glycol, butylene glycol, pentylene glycol, hexylene glycol, eryrite, 1,2,6-hexanetriol, and PEG-4, PEG-6, PEG-7 , Polyethylene glycol such as PEG-8, PEG-9, PEG-10, PEG-12, PEG-14, PEG-16, PEG-18, PEG-20, PEG-135, PEG-150), sugars and sugar derivatives (Fructose, glucose, maltose, maltitol, mannite, inosite, sorbite, sorbitol silandiol, sucrose, trehalose, xylose, xylate, glucuronic acid and salts thereof), ethoxylated Sorbitol (sorbet-6, sorbet-20, sorbet-30, sorbet-40), honey and hydrogenated honey, hydrogenated starch Hydrolyzate, and hydrogenated wheat protein, hydrolyzed milk protein, lecithin, phytantriol, hyaluronic acid and salts thereof, and PEG-20-acetate copolymers.

UVB-filters can be dissolved in oil or water.

Insoluble sunscreen pigments, ie finely dispersed metal oxides or metal salts, as well as a second sunscreen agent can also be added.

The addition of the dye has the advantage of allowing the user to visually feel that a particular (active) component is in the lipid phase. It also makes it easy to visually see the stability of the phase, especially the lipid phase, applied on the applicator. This makes it possible, for example, to observe whether the oily phase and the aqueous phase are mixed during storage.

Emulsifier

The lipid phase and / or aqueous phase in the articles of the invention may further contain one or more emulsifiers, which may be in W / O form (for use in the lipid phase) or O / W form (for use in the aqueous phase). . The addition of an emulsifier allows the incorporation of a hydrophilic component or active agent into the lipid phase and a lipophilic component or active agent into the aqueous phase.

Typically, nonionic emulsifiers with good skin compatibility are preferred. The combination of nonionic W / O and O / W emulsifiers results in improved feel properties. The lipid phase and / or aqueous phase may comprise 0 to 20% (w / w), in particular 0.1 to 15% (w / w), more specifically 0.1 to 10% of the emulsifier (s) relative to the total amount of lipid phase and / or aqueous phase. (w / w), especially in an amount of 0.1 to 5% (w / w) or 0.1 to 2% (w / w).

In general, they are mixtures of homologues whose average alkoxylation degree corresponds to the ratio of the starting amount of ethylene oxide and / or propylene oxide and the substrate used in the addition reaction. Depending on the degree of alkoxylation, these products are either W / O emulsifiers or O / W emulsifiers. C _{12/18 -fatty} acid mono- and diesters of adducts of ethylene oxide and glycerin are known as lipid providing components in the cosmetic art.

The polyol component of these emulsifiers may be derived from materials having at least two, in particular 3 to 12, more specifically 3 to 8 hydroxyl groups and 2 to 12 carbon atoms.

If it is desired to incorporate a water soluble active ingredient and / or a small amount of water onto the lipid, it may be advantageous to add an emulsifier and / or solubilizer selected from the group of nonionic O / W emulsifiers (HLB values: 8-18). These may be, for example, the already mentioned ethylene oxide adducts having a correspondingly high degree of ethoxylation of 10 to 20 ethylene oxide units for O / W emulsifiers and 20 to 40 ethylene oxide units for so-called solubilizers.

Particularly preferred W / O emulsifiers are incomplete esters of polyols, in particular mono-, di- or tri-, sesqui esters of fatty acids of polyols (especially C ₃ -C ₆ -polyols), for example glyceryl monoesters, penta Incomplete esters or carbohydrate esters of erythrite, for example saccharose distearate, or sorbitan mono-, di-, tri- or sesqui fatty esters, in particular stearate, oleate, erucate, ricinolate, Hydroxystearate, isostearate (and tartrate, citrate, malate) and the like. Preference is also given to products in which 1 to 30 moles, particularly 5 to 10 moles of ethylene oxide are added to these sorbitan esters.

Additional surfactant for both phases Holy priest / Emulsifier

Depending on the use of the product of the present invention, the lipid phase and / or aqueous phase may further contain zwitterionic, amphoteric, cationic and / or anionic surfactants.

Zwitterionic surfactants are tension functional compounds containing one or more quaternary ammonium groups and one or more -COO ^(-) or -SO ₃ ^(-) groups. Particularly useful zwitterionic surfactants are N-alkyl-N, N-dimethylammonium glycinates such as coco-alkyl dimethylammonium glycinate, N-acyl-aminopropyl-N, N-dimethylammonium glycy Nates such as coco-acyl aminopropyl dimethylammonium glycinate, and 2-alkyl-3-carboxymethyl-3-hydroxyethylimidazoline (with 8 to 18 C atoms each in the alkyl or acyl group) ) And so-called betaine such as coco-acyl aminoethyl hydroxyethyl carboxymethyl glycinate. Preferred zwitterionic surfactants are fatty acid amide derivatives whose INCI name is known as cocamidopropyl betaine.

Amphoteric surfactants may in particular be further added as auxiliary surfactants. Amphoteric surfactants are tension functional compounds which contain at least one free amino group and at least one -COOH or -SO ₃ H- group in addition to the C ₈ -C ₁₈ -alkyl- or acyl group and can form internal salts. . Examples of suitable amphoteric surfactants are N-alkyl glycine, N-alkyl propionic acid, N-alkyl amino butyric acid, N-alkyl iminodipropionic acid, N-hydroxyethyl-N-alkyl amidopropyl glycine, N-alkyl Taurine, N-alkyl sarcosine, 2-alkylaminopropionic acid and alkylamino acetic acid, each alkyl group having about 8 to 18 C atoms.

Most preferred amphoteric surfactants are N-coco-alkyl aminopropionate, coco-acyl amino ethylamino propionate and C _12-18 -acylsarcosine.

Anionic surfactants are characterized by having water-soluble anionic groups and lipophilic moieties such as carboxylate-, sulfate-, sulfonate- or phosphate groups. Particular anionic surfactants include linear alkyl- or alkyl ether sulfates having 12 to 18 C atoms, alkyl ether sulfates, alkyl ether carboxylates, acyl isethionates, acyl sarcosinates, alkalis of acyl taurine, Ammonium- or alkanol ammonium salts, and alkali- or ammonium salts of sulfosuccinate and acyl glutamate.

Quaternary ammonium derivatives can be used in particular as cationic surfactants. Ammonium halogenides, in particular chlorides and bromide, for example alkyl trimethylammonium chloride, dialkyl dimethylammonium chloride and trialkyl methylammonium chloride, for example cetyl trimethylammonium chloride, stearyl trimethylammonium chloride, distearyl dimethyl Ammonium chloride, lauryl dimethylammonium chloride, lauryl dimethylbenzylammonium chloride and tricetyl methylammonium chloride are preferred. Additional cationic surfactants are quaternary esters with good biodegradability, such as dialkylammonium methosulfate and methylhydroxyalkyl dialcoyloxy alkylammonium methosulfate (trade names Stepantex ^R and dehiquat) Dehyquart ^R ) -family of products). The term "Esterquats" encompasses quaternized fatty acid triethanolamine ester salts which have a beneficial effect on the softness of the phase, especially of the lipid phase. Further cationic surfactants are quaternized protein hydrolysates.

Manufacturing method

The invention also relates to a method of making a product as defined herein comprising contacting an applicator to a lipid phase composition and an aqueous phase composition as described herein. The method includes contacting the applicator simultaneously or sequentially with the lipid phase and the aqueous phase.

The method of contacting the applicator to the aqueous phase includes, for example, impregnating the applicator into the aqueous phase by dispersion, quenching, spraying, dropping, or the like through a bath. The method of contacting the applicator to the lipid phase is as previously described in the 'Geological Phase' section, with spraying, printing or direct contact methods (direct contact of the applicator with the application head with slit nozzles) preferred.

In certain instances, the methods of the present invention comprise contacting the applicator to the lipid phase and then to the aqueous phase.

The lipid phase and the aqueous phase may be applied at any point during the manufacturing process of the applicator, for example one or both phases may be applied during the manufacturing process of the applicator material. It is preferable to apply the lipid phase and / or the aqueous phase to the applicator after finishing the manufacturing process of the applicator.

The applicators thus obtained can be packaged individually in suitable packages, for example plastic wraps, boxes, etc., or in predetermined numbers, for example 10-30.

Applicators with different coatings and / or impregnations can be combined in one package. For example, there may be a series of applicators in which the amount of lipid phase is increased or decreased. It is also possible to alternate colored or colorless applicators.

Usage and characteristics

The product according to the invention has the advantage that during use the active ingredient (s), in particular the active ingredient (s) incorporated in the lipids, are best released to the skin.

The best release of the active ingredient can be achieved by using a lipid phase which is a solid lipid that has a melting point or melting range equal to or slightly above body temperature. Without being bound by theory, it is believed that this results in the faster melting of the lipid phase so that the active substance is delivered and released to the skin faster and more efficiently.

The best release of the active ingredient may be achieved by causing a local emulsification process on the skin during use of the applicator using an emulsifier suitable for one or both phases. Emulsifiers are preferably present in the aqueous phase. The local emulsification process may occur as a result of the body temperature melting the lipid phase, or the pressure applied during the use of the applicator, or both, and is generally due to both body temperature and pressure. In the case of local emulsification due to the influence of pressure, the emulsification process proceeds by the (limited) pressure exerted by the user when using the applicator, for example when rubbing or tapping the skin. This causes the two phases to contact to form an emulsion locally. Such local emulsification may be accomplished by contacting the lipid phase in the product with the water or aqueous phase prior to use, or may be achieved by using the product on wet skin.

In this local emulsification process, a limited amount of phase containing no emulsifier is incorporated into the phase containing emulsifier. In a preferred embodiment, the aqueous phase contains a small amount of emulsifier, and the emulsifier may be present, for example, in an amount of about 0.5 to about 5%, in particular about 1 to about 3%. In this case, part of the lipid phase is emulsified locally in the aqueous phase.

Although in a preferred embodiment the lipid phase is not present throughout the surface of the applicator, the lipid phase and the components contained therein are well released, especially when a local emulsification process is involved.

The best release of the active ingredient can also be achieved using both possibilities.

Products according to the invention are for example baby cleansing, facial or body cleansing, skin treatment or skin conditioning applicators (eg skin moisturizing and anti-aging), insect repellent applicators, powder applicators, toilet applicators, antiperspirant applicators As a personal hygiene product, including peeling applicators, after-sun treatments, sunscreen applicators, feminine cleansing applicators, endothelial lash applicators (preferably containing zinc oxide as active ingredient), and the like for infants or adults in a wide range of applications. Can be used for

The product according to the invention may have a use as a cleansing tool, which may be a more effective cleanser compared to a product comprising only an aqueous phase. This is due to the fact that they can remove both aqueous and oily contaminants and components. The product of the present invention may be particularly useful as an infant cleanser because it has the effect of removing waste debris and reducing the number of microorganisms that can cause infection.

The products described herein are useful as applicators of the active substances, in particular the active substances mentioned herein, or have both a use as a cleanser and an active ingredient as an applicator in one product.

The product of the present invention has an excellent ability to deliver the active ingredient to the skin, thus expanding the use of the applicator product as a carrier for many active agents, especially expensive active agents, which have not been used until now due to poor delivery rates. The product of the present invention not only delivers the active ingredient more effectively to the skin, but also provides the consumer with the benefit of allowing the active agent to be more evenly distributed on the skin and more permeable to the skin.

The product of the present invention has the additional advantage of having both cleansing performance and the delivery of the active ingredient to the skin in the same one product, namely the use of the product as it is. They also independently optimize the cleansing and skincare effects of the product and at the same time improve the delivery of skincare actives to the skin. Thus either of the two properties may take on a greater proportion, that is to say it may also have the ability to deliver certain advantageous ingredients or active substances to the skin, mainly for cleansing applications, or vice versa. The product can be designed for use in a product that remains the main benefit if it is not a cleansing but a more convenient form of use. The product of the present invention can further improve cleansing and skincare performance because the cleansing and skincare ingredients can be blended independently of the different phases.

Another advantage of the product of the present invention is that the applicator surface is modified due to the presence of lipid phases, which can provide a softer feel of the applicator material. The product also provides gentler cleansing (softer skin feel) due to less friction between the applicator and the skin.

The product of the present invention also offers the possibility of introducing or applying one product to two or more immiscible components, allowing the user to apply the immiscible product to one and the same product. In particular, it may include a product comprising a water soluble component as well as an oil soluble component, for example, an applicator comprising both active and water soluble active ingredients.

Another advantage is that the active agent is better delivered over the skin because the active ingredients are generally concentrated on the surface of the applicator material and are not included in the inner phase of a typical o / w emulsion.

Many of the lipid and aqueous phases described herein have the added advantage of being odorless (when no fragrance is added), being environmentally friendly and biodegradable.

The product of the present invention is particularly appealing since it is convenient and quick to use and the incorporated ingredients are easily and evenly distributed. They are also convenient for use by infants and children. The product also has a fast and effective cleansing performance.

From these advantageous properties, the products of the present invention can be used for a wide range of cosmetic and personal care products as well as other cleaning or cleansing applications such as cleaning hard surfaces.
