Abstract

  The present invention relates to a gelled cosmetic emulsion comprising a gelling system comprising an oil phase, an aqueous phase and a gelling system comprising an amount of at least one non-siloxane based polyamide sufficient to gel the emulsion. The polyamide can have ester, acid, tertiary amide, or amine end groups. The emulsion is stabilized by a sugar based emulsion stabilizer. The emulsions of the invention are substantially transparent and the color is particularly clear and distinct when a colorant is added. The emulsion is used in lipstick and mascara products, as well as other gel and stick products.

Description

  The present invention relates to a gel product for makeup and personal care gelled using polyamide as a gelling agent in an oil phase. More particularly, the present invention relates to a composition based on a stable emulsion comprising a polyamide gelling agent in the oil phase.

  Many gelled cosmetic emulsions use gelling agents, waxes, fillers, heavy oils, and plasticizers to develop the structure that makes the gel or stick composition. The structure made with these drugs and materials gives the product a balance between indeformability and stiffness depending on the desired product. For example, lipstick structures are traditionally formed by a mixture of wax and oil. However, these adjuvants, especially waxes, have the disadvantage that they cause opacity that reduces the color of the pigment. As such, the product has a dull, non-glossy, pale appearance. To overcome this problem, a greater amount of dye is added to the composition. Another disadvantage of adding wax is that the wax has poor adhesion to the skin and shortens the wear life of the product. For example, many widely used cosmetics including these materials, such as foundations, concealers, eyeliners, and lipsticks, are prone to fading, makeup slipping, and flaking off. Such products also have a dull appearance that is not always desirable. In addition, other adjuvants, such as heavy oil, can be felt uncomfortable on the skin and have a characteristic oily feel that may also be unpleasant. Thus, to address these problems, alternative gelling agents have been sought and specific polyamides have been used to gel cosmetics.

  The use of polyamides in cosmetics is known. For example, as described in US Pat. No. 3,148,125, polyamide resins are used in anhydrous lipsticks. A method for producing polyamide is disclosed, for example, in US Pat. No. 2,450,940. Polyamide resins are also used in deodorant or antiperspirant gels or sticks as disclosed in US Pat. Nos. 4,275,054 and 5,500,209 because of their odor absorbing properties. However, none of these references disclose emulsions gelled with non-siloxane based polyamides in combination with emulsion stabilizers containing ethylene oxide. For example, stick, soft gel, or transparent gel compositions disclosed in U.S. Patent Nos. 6,051,216, 5,603,925, and 5,998,570 and European Patent Application Nos. EP 1 068 855 and EP 1 068 856 are unstable emulsions, A single phase composition or a siloxane based polyamide is used. Siloxane polyamides have been developed because they are alleged to have the ability to provide less tacky compositions in addition to their ability to gel the composition. However, siloxane-based polyamides are not compatible with various oils, such as hydrocarbon oils, and due to their low tack, their adhesive properties are very poor and during product application to the skin or hair. This is undesirable for products that require at least an initial phase of adhesion. For example, products such as mascara require some degree of tackiness when applied, but after drying, the mascara tackiness needs to change to a comfortable feel on the eyelashes, so a cosmetic emulsion system It is desirable to use other polyamides. To date, it has not been known to fine tune the adhesive properties of cosmetic two-phase products containing polyamide resins as gelling agents. For products where the degree of stickiness needs to change over time and during their use, the compositions so far have either been too sticky or insufficient. . Thus, the emulsion of the present invention gelled with non-siloxane polyamide is not known to date. There remains a need for stable cosmetic emulsions that adhere to the skin and are gelled by polyamide resin systems that function in a variety of cosmetic emulsion systems. The emulsion system of the present invention is also desirable to allow incorporation of water-soluble ingredients in products containing the emulsion.

SUMMARY OF THE INVENTION The present invention relates to gelled cosmetic compositions, in particular oil-in-water or water-in-oil emulsions, comprising at least one sugar-based emulsion stabilizer and at least one non-siloxane-based polyamide resin. About. The prepared emulsions are not themselves transparent, but become substantially transparent after application to the skin. The use of a polyamide resin as a gelling agent is not novel per se, but it is surprising to incorporate it into the coloring composition of the present invention comprising, for example, an alkyl glucoside having about 8 to 16 carbon atoms as an emulsion stabilizer. is there. The cosmetic emulsion of the present invention also includes a pigment component in an amount greater than about 2.0% by weight of the composition. Polyamides are very polar and emulsions containing large amounts of polyamides tend to be sticky and difficult to stabilize in the presence of colorants, so color cosmetic emulsions using polyamide resin as the main gelling agent It is particularly difficult to gel.

  The present invention also includes a method of making an emulsion system of the present invention that may include a multi-emulsion system. The emulsion products are particularly transparent and transfer resistant when they are applied to the skin and dried. Compositions containing these emulsions have a brighter and brighter color on the skin after application because of the transparent film that adheres to the skin without stickiness. The emulsion system of the present invention dries faster than systems containing other polyamides and lasts even after the water has evaporated. Furthermore, the gels and sticks made with the emulsion system of the present invention are less brittle, do not substantially syneresis, and are more creamy because the three-dimensional structure formed by the polyamide resin is partially interrupted by the aqueous phase. Has a nice texture.

Detailed Description of the Invention The gelling system of the present invention is an emulsion stabilizer based on at least one non-siloxane based polyamide resin and at least one sugar. The polyamide resin used in the present invention is defined as a polymer having a repeating unit of an amide group as an essential part of the main chain of the polymer and an acid, amine, or ester end group. Polyamide gelling agents can be used to produce soft gel or stick compositions in emulsified systems. Therefore, it is preferable that the polyamide resin is not highly crosslinked by hydrogen bonding. In contrast to thermosetting resins, polyamides are characterized as thermoplastic resins. Based on complexing fatty acids, esters, and amines, the polyamides used in the present invention are water insoluble. Polyamides are available in the solid form of 100% polyamide or as a percentage of mineral oil, usually about 80% polyamide. Examples of commercially available polyamides useful in the present invention are prepared from dimer of partially hydrogenated _C18 unsaturated fatty acids, azelaic acid (nonanedioic acid), ethylenediamine, hexamethylenediamine and stearic acid. Versamid 1655 (Cognis (formerly Henkel Corporation), Ambler, PA), the polyamide series Unirez and Uniclear (Arizona Chemicals Corporation, Jacksonville, FL), or nylon 6, nylon 66, and nylon 610 terpolymers An Elvamide (DuPont, DE). Additional polyamides are disclosed in US Pat. Nos. 4,820,765, 5,719,255, 5,807,968, 6,111,055, and 6,054,517, the contents of which are incorporated herein by reference. These references are not aware of the ability to make stable emulsion products, so the benefits of cosmetic emulsions containing water that incorporate polyamide gelling agents and surfactants containing C _1-5 alkylene oxides. Not aware. For example, U.S. Pat.No. 5,783,657 is anhydrous and U.S. Pat.No. 5,998,570 preferably removes water when forming a polyamide, and the composition includes a non-aqueous liquid, preferably a low polarity liquid, as a solvent. It is disclosed.

  The aqueous phase of the cosmetic emulsion of the present invention comprises about 0.05 to 90.0%, preferably 1.0 to 70.0% of the weight of the emulsion. The aqueous phase consists mainly of water, which can take the form of various aqueous solutions such as rose water and black tea. Thus, the aqueous phase is very suitable for delivering water soluble active substances and other water dispersible substances such as film formers, surfactants and emollients. The non-aqueous phase may comprise any type of cosmetically acceptable volatile or non-volatile oil (including oil esters), depending on the application method of the product and the degree of gelation desired. Examples include, but are not limited to, hydrocarbon oils such as isododecane, silicone oils such as cyclomethicone, polyorganosiloxanes such as phenylmethicone and dimethicone, castor oil, and hydrogenated vegetable oils. Can be mentioned. Preferably, in mascara, the oil is volatile, such as volatile hydrocarbon oil or silicone oil, while lipstick is a mixture containing both volatile and non-volatile oils, each amount Depends on the type of lipstick desired. Suitable non-volatile hydrocarbons include, but are not limited to, isoparaffin, squalane, or petrolatum, or mixtures thereof. Regardless of the amount of volatile and / or non-volatile oil, the total oil phase is in an amount of about 5 to about 95%, preferably 10 to 80%, more preferably about 10 to 40% by weight of the composition. Exists.

  The emulsion of the present invention is prepared by adding an amount of polyamide resin sufficient for gelation to the oil phase. The amount of polyamide resin used in the present invention is about 1 to about 90%, preferably about 2 to 40% of the weight of the composition. The amount of polyamide is “sufficient for gelling” and, as used herein, causes an increase in the viscosity of the emulsion, preferably the viscosity is 25%, more preferably 50%, most preferably 75%. By increasing the amount of polyamide in the oil phase is meant. This increase in viscosity is sufficient to form a thick gel or a solid with stick firmness. Gel strength and sticks are known to those skilled in the art. At low contents, the polyamide promotes gel formation, whereas at high contents it is used to make stick products. Although it is difficult to quantitatively distinguish between cosmetic gels and sticks, in general, gels are more viscous than liquids, but are not as stiff as sticks and are not self-supporting. It is accepted by those skilled in the art that the gel maintains some degree of deformability, whereas the stick is self-supporting and substantially hard and does not deform.

  Another component of the present invention is an emulsion stabilizer with a silicone bone core that contains a sugar-based moiety and no alkylene oxide units. Thus, as used herein, the term sugar-based emulsion stabilizer refers to a stabilizer based on a sugar and / or glyceryl moiety having a silicone bone core and no alkylene oxide units. Sugar based emulsion stabilizers may be nonionic, cationic, anionic or amphoteric. Nonionic sugar-based emulsion stabilizers included in the present invention include alkyl polyglycosides, alkyl glucose esters, aldobionamides, gluconamides, glyceramides, glyceroglycolipids, polyhydroxy fatty acid amides (glucamide), and Selected from the group consisting of mixtures thereof. In particular, the Glucopon® and Plantaren® series products from Henkel Corporation (Ambler, PA) are emulsion stabilizers useful in the present invention.

  Emulsion stabilizers based on cationic sugars are, for example, at least one hydrocarbon group having 6 to 24 carbon atoms and at least one quaternary ammonium group, the at least one substituent of which is a sugar by a glucoside bond. Cationic sugar surfactants that include those that are groups containing alkyleneoxy bonded to the residue. These are disclosed in US Pat. Nos. 6,503,880, 6,432,907, and 5,773,595. Anionic and amphoteric surfactants are acyl sucrose derivatives as disclosed, for example, in US Pat. No. 6,184,196.

  Preferably, the emulsion stabilizer is one having a certain ratio of sugar moieties to siloxane units (eg, about 0.5-10%). Surprisingly, it has been discovered that a stable emulsion containing a polyamide resin as a gelling agent can be obtained according to the present invention. Although it is known to gel oil-based systems with polyamide resins, to date, these systems have been primarily single phase. In particular, it has not been known that stable two-phase compositions, and particularly stable cosmetic emulsions, contain non-siloxane based polyamide gelling agents due to their stability issues. Non-siloxane based polyamides are known to be viscous. Therefore, their use is limited and is most suitable for coatings, paints, inks, epoxy resins, adhesives and the like. Also, their use in cosmetics has been limited mainly to single-phase systems such as anhydrous lipsticks and deodorants. Also, these types of cosmetic formulations are very different from the difficulties of formulating stable emulsions in cosmetic emulsions, especially colored cosmetics.

  The emulsion preparation method of the present invention uses the basic steps known to those skilled in the art as emulsion preparation methods. The non-siloxane based polyamide and other components of the oil phase may be prepared separately, but are mixed or added to the oil phase prior to mixing with the aqueous phase to make an emulsion. Emulsions of the present invention comprising a gelling system use polyamide as the main gelling agent in the gelling system or, for example, cetyl dimethicone copolyol, acrylate copolymer, dextrin fatty acid ester, carbopol, dibenzyl monosorbitol acetal, Other naturally-occurring or synthetic gels known to those skilled in the art and widely used, such as polyethylene wax, beeswax, carnauba wax, candilla wax, bayberry wax, rice wax, acylglutamic acid diamide, ester, fatty alcohol, etc. Agents or thickeners can be prepared by adding to the oil phase of the present invention. Preferably, however, the composition of the present invention does not contain wax.

  Surprisingly, it has been found that the presence of sugar-based surfactants stabilizes emulsion systems containing polyamides as gelling agents. Considering the difficulty of formulating cosmetic emulsions, plus the difficulty of incorporating non-siloxane polyamide gelling agents into the emulsion, it is surprising that greater stability is achieved using sugar-based emulsifiers It is. While not wishing to be bound by any particular theory, sugar-based emulsifiers can form hydrogen bonds with polyamide gelling agents, so that increased stability and gelation are achieved with sugar-based emulsifiers. Conceivable. The emulsion stabilizer may be a single surfactant or a combination of a plurality of surfactants. Emulsion stabilizers promote the coexistence of polyamide resins in a two-phase system and not only increase the stability of emulsions containing polyamide resins based on non-siloxanes as gelling agents, but also affect the gelling activity of polyamide resins. give. Since polyamide resins are water-insoluble, it is known that stability problems arise when used as a gelling agent in emulsions with commonly used cosmetic oils. Specifically, agglomeration occurs or phases separate in a short time, for example, about a few hours to a few months. However, the present invention has discovered that this problem can be overcome by an emulsion stabilizer that can be present in the oil phase, the aqueous phase, or both. As a result, the polyamide resin can coexist in the emulsion stabilizer at room temperature and / or high temperature. Furthermore, the emulsion is stable for about 6 months, preferably about 1 year, more preferably about 2 years, as measured by an accelerated stability test known to those skilled in the art.

  More preferably, the sugar-based emulsion stabilizers of the present invention are primarily nonionic sugar-based surfactants. The emulsion stabilizer may be dimethicone / caprylic acid / capric acid triglyceride. Examples of solvents include, but are not limited to, emollients such as low polar liquid emollients, straight and branched chain fatty alcohols, cetyl alcohol and isocetyl alcohol, monovalent or polyvalent Alcohols such as propylene glycol and dipropylene glycol, fatty acid esters such as cetyl acetate / acetylated lanolin alcohol are mentioned.

  In addition to sugar-based stabilizers, the emulsion is stabilized by adding a nitrogen-based soap-based emulsifier, or an alkanolamide of a fatty acid, preferably laurylamide MEA or stearylamide MEA, and derivatives thereof. Can different types be combined? For example, a lipstick containing a combination of laurylamide MEA (monoethanolamine) and a sugar-based stabilizer is particularly useful for providing stability against the development of syneresis, even when the lipstick is in the form of a water-in-oil emulsion. It is valid.

  Other features of the emulsions of the present invention include substantial transparency when applied to the skin, good adhesion to the skin without stickiness, and their substantial transition resistance. The emulsion need not contain wax because the presence of the polyamide gelling agent eliminates the need to create a structure with a large amount of wax. Since waxes form an opaque oil phase (ie when light is scattered by the wax microstructure), the use of polyamide gelling agents in the presence of an emulsion-based aqueous phase is based on traditional waxes. To improve the emulsion. This reduces the sharpness of the color because the opaque oil phase impairs the original appearance of the color even when applied to the skin. In addition, wax has poor adhesion to the skin. Therefore this will not last long. It is widely used in mascara, lipsticks and other products, but due to the presence of wax, these products are prone to transfer from the skin to other unwanted things (eg clothes, cups) and in a short time. Fading, as well as makeup collapse and flaking off are common problems. However, the emulsion gelled with the polyamide of the present invention adheres well to the skin. The strong adhesion to the keratin substrate is thought to be due to hydrogen bonding between the polyamide and keratin. A surprising advantage of the present invention is that the emulsion product can be given the conflicting property of sticking to the skin without a sticky feel. It is widely seen that the measures taken to increase the adhesion of the composition lead to a corresponding increase in the viscosity of the composition. However, the emulsions of the present invention overcome this mutual exclusivity and have both a comfortable creamy feel and good adhesion to the skin.

  In addition to gelling a stable emulsion, the polyamide functions to maximize color integrity because the emulsion becomes substantially transparent or translucent when applied to the skin and dried. As used herein, “substantially transparent” means that more than 75%, preferably 80%, more preferably 90% of the light can penetrate the oil phase. Thus, the term “transparent” as used herein refers to an inventive cosmetic stick product having translucent or transparent light transmission properties, and also transmits light without appreciable scattering, thereby A transparent object with the characteristic that the object behind it is completely visible. The term “translucent” refers to an object that is partially transparent. Since the object accepts and scatters light, the object behind can be seen but cannot be clearly identified. The term “opaque” refers to an object that does not transmit visible light. An opaque object does not have any degree of transparency.

  In addition, the cosmetic emulsion of the present invention includes a colorant component including one or more colorants. The term “colorant” as used herein includes pigments, dyes, dyes, colorants, combinations thereof and the like. Any colorant acceptable as a cosmetic can be used in the emulsion of the present invention. The color of the product after adding the colorant is strong and clear when applied to the skin. Suitable organic dyes are, for example, natural dyes, monomeric and polymeric synthetic dyes, or combinations thereof. Examples of organic dyes include, but are not limited to, phthalocyanine blue and green dyes, and azo red dyes such as naphthol red dyes. Other suitable aromatic dye compounds include, but are not limited to, azo, triphenylmethane, indigo, anthraquinone, and xanthine dyes, and D & C and FD & C dyes such as FD & C Blue No. 1, FD & C Green No. 5, FD & C Red No. 40, and FD & C Yellow No. 5. Also useful are lakes, which are pigments formed by precipitating organic dyes and absorbing them into insoluble bases such as alumina, barium or calcium hydrates. Particularly preferred lakes are mainly FD & C or D & C lakes and mixtures thereof. The concentration of the colorant will vary depending on the color or shade of cosmetic desired, but the colorant component will generally comprise more than 2.0%, preferably more than 5.0% of the total weight of the composition.

  The colorant may be an inorganic pigment. Minor amounts of inorganic pigments are included, and preferably the inorganic pigments have a small particle size, such as submicron particle size, which is easy to disperse and can maintain the transparent appearance of the cosmetic. Examples of inorganic pigments include, but are not limited to, iron oxide (yellow, red, brown or black), ultramarine, chromium hydroxide green, chromium oxide, titanium dioxide (white), ferrocyanide ( III), ammonium iron (III) ferrocyanide, and mixtures thereof. The dye can be pulverized, for example, by a rolling mill, or the dye can be purchased as a pre-ground, for example, as a mixture containing water, polysaccharides and black iron oxide. . It is difficult to incorporate dyes, pigments and colorants into emulsion systems, particularly emulsion systems comprising emulsion stabilizers comprising non-siloxane based polyamides and ethylene oxide as gelling agents. Surprisingly, however, the color of the cosmetic emulsion according to the invention gives the maximum color effect after application to the skin. The color is deep, clear and clear.

  The active ingredient to be mixed with the emulsion of the present invention having polyamide as a gelling agent preferably does not include an antiperspirant active substance, particularly one that is an acidic metal salt. Examples of active substances that can be used in the present invention include, but are not limited to, sunscreen active substances, whitening agents such as antioxidants, antibacterial agents, analgesics, anesthetics, acne inhibitors.

Incorporation of the active substance into the formulation is determined by its solubility and / or stability when combined with an emulsion gelled with a non-siloxane based polyamide of the present invention. As used herein, the term “sunscreen” refers to effectively absorbing ultraviolet light having a wavelength of about 280 to about 400 nm and / or by reflecting or scattering said ultraviolet light from the skin surface. It refers to a substance that can protect the skin from ultraviolet rays as described above. Examples of sunscreens that can be incorporated into the compositions of the present invention in the above sense are titanium dioxide, zinc oxide, benzophenone, octyl dimethyl PABA, amyl dimethyl PABA, octyl methoxycinnamate, 2-ethoxy p-methoxysilicate. Cinnamic acid, oxybenzone, homosalate, phenyl salicylate, avobenzene, glyceryl p-aminobenzoate, ethyl benzoate-p-glycosylimide, and the like. In the formulation, the sunscreen agent is used in an amount that the drug is normally used. Preferably, the active substance is not acidic. However, the choice of delivery mode of the additional active ingredient is limited to the delivery mode selected for the composition.
