Description

[0001] COLOR CHANGING COMPOSITION WITH POLYOL [0002]

The present invention relates in particular to a color-changing composition in the form of a clear gel containing one or more polyols and / or glycols useful for the care, hygiene and / or make-up of keratinous materials.

In particular, the color changing composition according to the present invention may be applied to any type of cosmetic composition such as foundation, face powder, eye shadow, concealer product, blusher, lipstick, lip balm, lip gloss, lip pencil, eye pencil, eyeliner, mascara, (BB) products (Blemish Balm products capable of covering defects), tinted cream or sunscreen products, preferably foundations or BBs, such as make-up products, skin colorants, care products such as care creams, Product.

The compositions of the present invention are especially compositions intended to be applied to keratinous materials, especially skin and more particularly facial skin, such as facial care or makeup products for the face.

In another embodiment, the composition of the present invention is mascara.

In another embodiment, the composition of the present invention is a lip product, in particular lip gloss, lip balm or lipstick.

Cosmetic compositions, especially foundations, are typically used to mask skin imperfections such as redness and / or marks, as well as providing aesthetic color to the skin. In this regard, a number of formulations have been developed to date.

In this respect, there is an increasing interest in cosmetic products that provide color variations for external factors, such as, for example, shear forces.

In general, this object is achieved by including a microencapsulated colorant in the cosmetic composition, wherein upon application onto the skin, the composition provides the expected color change. More particularly, the change in hue is provided by the colorant-containing microcapsules, which, upon rupture by application of a mechanical force, release the entrapped colorant into the composition and change its color. Mechanical action, such as rubbing, spreads the topical composition and penetrates it into the skin. The instant color change of the composition provides a visual aesthetic effect.

Different types of captured colorants and more particularly pigment-containing microcapsules are already available. These mainly depend on the capture type and / or encapsulation type of the substance (s).

Thus, as pigments encapsulated by microcapsules in acrylic acid and / or methacrylic acid polymers or copolymers, mention may be made, for example, of ethyl acrylate / methacrylic acid sold by Tagra and described in WO-A-01/35933 Microcapsules containing a copolymer of an acid ammonium salt can be mentioned. Also, at TAGRA BIOTECHNOLOGIES, the names BLACKCAP1 ^ⓒ , YELLOWCAP1 ^ⓒ , REDCAP1 ^ⓒ , BLACKCAP3 ^ⓒ , YELLOWCAP3 ^ⓒ , REDCAP3 ^ⓒ Commercially available encapsulated pigments may be mentioned.

As the pigment encapsulated in microspheres in cellulose derivatives, for example, sphere containing cellulose, hydroxypropylmethylcellulose (marketed by Induchem under the name Unisphere ^ⓒ ) can be mentioned.

Pigments encapsulated by microcapsules in polymers of polyesters, polyaminomethacrylates, polyvinylpyrrolidone, hydroxypropylmethylcellulose, shellac type and mixtures thereof are disclosed, in particular, in U.S. Patent Application US 2011/0165208 to Biogenics , And those marketed by Biogenics under the name Magicolor ^ⓒ can be mentioned.

Other pigments encapsulated by microcapsules may also be mentioned, such as those disclosed in JP2011-79804 (DAITO), and these pigment-encapsulated double-layer microcapsules comprise at least three of the following: (a) mannitol, b) hydrogenated lecithin, (c) polymethyl methacrylate, (d) cellulose and (e) shellac.

This double-layer microcapsule is one of the microcapsules preferably used according to the present invention and does not contain an uncoloured core but instead contains a colored inner layer containing the above-mentioned components, Are all mixed together and granulated.

However, in some colorant-containing microcapsules, when applied to different environments and conditions, it may be difficult to keep the colorant permanently for a long period of time. This is the case for pigments, oil-soluble dyes, and water-soluble dyes. Thus, it was found that some of the microcapsules described in the patents and publications bleed gradually over time during the prolonged release of the coloring agent or at elevated temperatures. Color bleed can be achieved through contact with moisture and / or other ingredients commonly found in cosmetic formulations, such as alcohols or glycols, surfactants, silicones, oils, preservatives, Occurs when the pigment travels through or away from the microspheres / microcapsules. Leaching or bleeding of colorants in cosmetic compositions can impair the long-term visual effects of cosmetics both in the container and on the substrate.

Furthermore, some pigment-containing microcapsules may give a lower cover effect than anticipated.

Furthermore, some pigment-containing microcapsules are destroyed immediately upon application and sudden color changes appear, so that the intermediate stage of such color change is not recognized or the color gradation can not be adjusted.

Furthermore, some pigment-containing microcapsules may have some stability problems with cosmetic compositions and related solvents / ingredients.

Further, some pigment-containing microcapsules may have the appearance of gray giving an unattractive color in the bulk of the cosmetic composition.

Finally, some microcapsules may provide an uncomfortable and / or undesirable feel when the cosmetic formulation comprising it is applied on the keratinous material.

More particularly, some topical compositions containing microcapsules may provide a kind of skin feel or wear to the user due to lack of deformability and lack of softness.

Accordingly, there is a need to provide a cosmetic gel comprising colorant-containing microcapsules with improved bleed resistance. In this respect, there is a demand for colorant-containing microcapsules in which the capsules have excellent shatter resistance and exhibit improved bleed resistance. In cosmetic compositions, where the dye is not permanently retained, this may impair the long-term visual effect of the cosmetic.

It is also desirable to provide an adjustable cosmetic composition by varying the desired coloring or gradation pattern of the application method or strength on the skin, or the use of microcapsules containing different coloring agents.

In addition, it is required to provide a stable cosmetic composition with various related solvents / components.

It is also desirable to provide cosmetic compositions in which the microcapsules are not visible or visible within the bulk of the composition according to the desired appearance.

Also, there is a need for a cosmetic composition containing pigment-encapsulated microcapsules that does not cause an uncomfortable feeling to the user upon application.

There is also a need to provide a cosmetic composition containing pigment-encapsulated microcapsules which, upon application, is rapidly and rapidly degraded to provide a coloring composition without any granular aspect while providing a feeling of liquid on the skin. In particular, the composition may exhibit different hue or color gradients depending on the rubbing strength.

In addition, there is a need to provide pigment-encapsulated microcapsules having sufficient hardness to be blended in industrial processes without modification. Advantageously, the hardness of the microcapsules is not significantly reduced during the manufacturing process.

There is a need to provide a cosmetic composition which imparts and / or improves the microcapsules with deformability.

There is a need to propose a cosmetic composition provided with a colorant-containing microcapsule that softens the microcapsules and thereby provides the user with a comfortable and soft feel when applied to the skin.

There is a need to provide a cosmetic composition which has a good fresh feeling and good application and sliding properties and at the same time avoids slippery feeling, airtightness and abrasion effects.

Surprisingly and advantageously, the composition according to the invention meets the requirements of the prior art.

The present invention also relates to a cosmetic method for the care and / or make-up of keratinous materials, the method comprising applying a composition as defined in accordance with the invention onto said keratinous material, in particular on the skin.

The term "physiologically acceptable medium" is intended to mean a medium which is particularly suitable for applying the products of the present invention to keratinous materials, particularly skin and more particularly facial skin.

The "physiologically acceptable medium" includes the aqueous phase used according to the present invention.

For purposes of the present invention, the term "keratinous material" is intended to include skin, mucous membranes such as lips, nails and eyelashes. The skin and the lips, especially the facial skin, are most particularly considered in the present invention.

As can be seen from the following examples, the compositions according to the present invention have proven advantageous in several respects.

Encapsulation of the colorant prevents the formation of the cosmetic composition and undesired re-aggregation of the pigment during long-term storage.

Because the microcapsules of the present invention have the ability to expand or soften upon contact with the aqueous phase as defined below, they are advantageously deformable upon application to the keratinous material and consequently provide a soft feel to the user. Furthermore, its small size contributes to the coating not producing any uncomfortable or undesirable, grainy feel of the particles.

However, the microcapsules of the present invention are sufficiently soft to rupture when very weakly rubbed or pressed on the skin to release its contents, but nevertheless, during the preparation of the corresponding color changing composition, even during industrial processes and storage And is durable enough to prevent the coating from collapsing.

In addition, since the microcapsules of the present invention do not cause discoloration of the equipment during the manufacturing process, it is possible to use conventional equipment for manufacturing the composition of the present invention.

Thus, the microcapsules of the present invention can be used in a wide variety of applications, as they will shield the inherent hue of the encapsulated colorant, increase the stability of such colorant to degradation, and prevent undesirable release of the encapsulated colorant into the composition during the manufacturing process and long- Because of this, I am especially interested.

Finally, the composition of the present invention also has the advantage of meeting consumer expectations in terms of cosmetic products.

In another aspect, the subject matter of the present invention is also directed to a cosmetic method comprising at least a step of applying at least a portion of a gel composition according to the invention onto a keratinous material, in particular on the surface of the skin.

In the present invention, "color changing composition" means a composition in which the hue before application differs from the hue after application, and this difference is visually observable.

In particular, this color changing composition may be related to the color-difference DELTA E of the CIE Lab system 1976 (pre-and post-application DELTA E) values.

The ΔE is defined by the following equation:

Wherein L ₁ , a ₁ , b ₁ are variables in the colorimetric space of the first color (pre-application composition), and L ₂ , a ₂ , b ₂ are variables in a second color And composition after homogenization).

The values can be measured using a spectrophotometer or Chrosmasphere (for compositions applied on the skin).

The term "colorant" refers to synthetic or natural dyes, inorganic pigments, such as metal oxides, or lakes, and any combination thereof, selected from organic pigments such as any of the well known FD & do. Thus, colorants useful in accordance with the present invention may be oil-soluble or oil-dispersible, or may have a limited solubility in water.

In a preferred embodiment, the colorant is an inorganic pigment, more preferably a metal oxide.

Generally, colorant microcapsules having an average particle size of about 800 탆 or less in diameter are used in accordance with the present invention. Preferably, the average particle size is less than about 400 microns in diameter of the colorant microcapsules for skin care application.

As an example, WO2008 / 139053 can be mentioned, which relates to the preparation of an ellipsoidal multilayer capsule comprising concentric layers of sugar cores and pharmaceutically active agents. After fixation on the core of the pharmaceutically active agent is achieved by impregnation, pulverization or projection, the first layer is dried before application of the second layer.

Fluid bed processes are described, for example, in Teunou et al. (Fluid-Bed Coating, Poncelet, 2005, D. Food Science and Technology, Boca Raton, FL, United States) Volume 146 Issue Encapsulated and Powdered Foods, Pages 197-212). A particular feature of the fluidized bed process is that the core induces coated particles that are well encapsulated, compared to spray drying, which induces the matrix with the core material to be randomly dispersed in the polymer.

In a preferred embodiment, the microcapsules are obtained by a fluidized bed process.

In this embodiment, preferably one or more layers of microcapsules are obtained by a fluidized bed process.

In certain embodiments, the outer layer is obtained by a fluidized bed process.

Preferably, the fluidized bed process carried out in accordance with the present invention includes a Wurster process and / or a tangential spray process. Such a process enables the production of spherical capsules having a core surrounded by at least one circumferential layer, in contrast to the pelletizing process.

When the entire process of producing the layer surrounding the core of the microcapsule according to the present invention is carried out by a fluidized bed process, the microcapsule layer is advantageously regular, concentric and has a uniform thickness.

According to another embodiment, the color changing composition according to the present invention is present in the form of a foam containing from 1 to 30% by weight of the microcapsule composition.

The term " foam form composition "and the term" foam type formulation "will be understood to mean a composition containing the vapor phase (e. Another synonym is "bulk expanded composition ".

According to one embodiment, the foam composition is obtained without any propellant (non-aerosol foam).

In another preferred embodiment, the foam composition is obtained using a propellant (aerosol foam).

Compositions in foam form according to the present invention can be obtained from compositions of the present invention that are used as packaged "base compositions" in products. The article may comprise a propellant in addition to the base composition.

Accordingly, the present invention further relates to a product comprising:

a. A container defined by one or more compartments;

b. The composition of the present invention contained in said compartment,

c. A propellant for compressing the composition into the compartment; And

d. A dispensing head having an inlet for delivering said compressed composition in the form of a foam, said inlet being selectively adapted for fluid distribution in said compartment.

According to another embodiment, the invention relates to a kit comprising one of the above defined products and an applicator.

The composition in the form of a foam according to the present invention is prepared stably in the form of a composition using the composition of the present invention and a composition of air or an inert gas.

The air or inert gas may be present in an amount of from 10% to 500%, preferably from 20% to 200%, for example from 30% to 100%, of the volume of the composition in the form of a foam.

The volume can be calculated by comparing the density of the base composition and foam form composition.

In addition to air, the gas from which the foam-like composition can be obtained is in particular an inert gas, for example nitrogen, carbon dioxide, nitrogen dioxide, an inert gas or a mixture of such gases. When the composition contains a compound sensitive to oxidation, it is preferable to use an oxygen-free gas such as nitrogen or carbon dioxide.

The amount of gas introduced into the base composition is adjusted to adjust the density of the foam-form composition to a desired value, for example, 0.12 g / cm ³ or less.

The composition of the form of the invention, for example 0.12 g / cm ³ or less, such as 0.02 to 0.11 g / cm ^3, preferably, may have a density in the range of 0.06 to 0.10 g / cm ^3, the density Is measured at a temperature of about 20 DEG C and atmospheric pressure according to the following protocol.

Density measurement

The test was carried out with 50 ml of the composition placed in a 50 ml abrasive Plexiglas® balance base (V ₁ ) with a cylindrical filling space of 30 mm in height with a bottom having a diameter of 46 mm. The scale base has a 10 mm thick bottom and 12 mm thick side walls.

Prior to measurement, the composition to be characterized and the balance support are maintained at a temperature of about 20 占 폚. Adjust the zero point with the scale support and record the weight value (M ₁ ). The foam-form composition is then placed on the scale base to fill the entire volume, avoiding air bubbles when filling the scale base. The assembled state is allowed to stand for 10 seconds to allow the mousse to fully expand. Then, the lid of the balance support is removed and weighed (M ₂ ). The density is evaluated according to the usual equation ρ = (M ₂ -M ₁ ) / 50.

Stability measurement

The foam-like composition according to the present invention exhibits satisfactory stability, which can be calculated by measuring the volume (V ₂ ) of the mousse remaining on the balance pan after 10 minutes according to the protocol described above for the density measurement.

The ratio V ₂ / V ₁ corresponds to the ratio of the volume of the foam-form composition after 10 minutes and the volume of the foam-form composition after 10 seconds.

The expression "satisfactory stability" corresponds in particular to a composition in the form of a foam having a ratio V ₂ / V ₁ of above 0.85, in particular above 0.90, for example above 0.95.

For a given weight of the foam-form composition, the volume of the foam-form composition is inversely proportional to the density of the foam-form composition. Thus, the ratio between the density of the foam-form composition measured after 10 seconds and the density of the foam-form composition measured after 10 minutes may be greater than 0.85, in particular greater than 0.90, for example greater than 0.95.

The propellant may represent less than 20 wt%, especially 1 wt% to 10 wt%, such as 2 to 8 wt%, of the weight of the base composition. The propellants that may be used may be selected from carbon dioxide, nitrogen, nitrogen dioxide, volatile hydrocarbons such as butane, isobutane, propane, ethane, pentane, isodecane or isohexadecane and mixtures thereof.

It may in particular be a propane / butane mixture (liquefied petroleum gas or LPG) in a range of 0.1 to 1, in particular 0.31 in weight ratio [propane / butane].

The pressure of the propellant in the aerosol, for example the propane / butane mixture, may range from 0.20 to 0.50 MPa, for example from 0.20 to 0.40, in particular from 0.25 to 0.35 MPa.

The composition in the form of a foam employed in the present invention may be prepared by mixing, stirring or dispersing a pressurized gas such as air, a chlorofluorocarbon compound, nitrogen, carbon dioxide, oxygen or helium, mixing and stirring in the presence of a foaming agent such as a surfactant . &Lt; / RTI >
