Definitions
- the present invention relates to a skin makeup composition and more particularly a composition of fluid foundation type, having optimized application qualities.
- Polymethyl methacrylates are generally in the form of hollow white spherical particles generally of the order of a micrometre in size. These particles have the particular feature of having high water or oil adsorption capacity, which is particularly advantageous in cosmetic formulations. Thus, in oil-based cosmetic compositions, by partially adsorbing these oils, they give the corresponding composition a dry and powdery feel. Moreover, in formulations of lipstick base type, they allow 10% to 30% of water to be incorporated. These hollow spherical particles of polymethyl methacrylate have thus already been proposed for encapsulation or reservoir purposes, in dry oils, water-based lipsticks and free or compacted powders with a high oil or water content.
- the inventors have found, unexpectedly, that the presence of polymethyl methacrylate can also be a deciding factor for optimizing the properties of cosmetic compositions such as, especially, “fluid” foundations, in terms of application.
- the main subject of the present invention is a fluid cosmetic composition in the form of a water-in-oil emulsion comprising a liquid fatty phase, an aqueous phase and a dimethicone copolyol, characterized in that it comprises solid particles of polymethyl methacrylate and in that the liquid fatty phase comprises isododecane, the said composition being free of cyclotetrasiloxane.
- the present invention is also directed towards a fluid cosmetic composition in the form of a water-in-oil emulsion comprising a liquid fatty phase, an aqueous phase, a dimethicone copolyol and a C 8 -C 22 alkyl dimethicone copolyol, characterized in that it comprises solid particles of polymethyl methacrylate and in that the liquid fatty phase comprises a volatile hydrocarbon-based oil, the said composition being free of cyclotetrasiloxane.
- a subject of the present invention is also a process for making up the skin, characterized in that it comprises the application to the skin of at least one composition in accordance with the invention.

- the polymethyl methacrylate powders with a density of greater than 0.5 are more particularly advantageous for prolonging the slip qualities of the composition over time.
- the polymethyl methacrylate particles with a density of less than or equal to 0.5 these would appear to be more advantageous in terms of handling of the the said composition. In other words, the foundation can be put on more quickly.

Abstract
Description
- The present invention relates to a skin makeup composition and more particularly a composition of fluid foundation type, having optimized application qualities.
- In general, producing a satisfactory makeup effect on the skin using a foundation involves being able to distribute the the said foundation uniformly over the entire surface to be made up. To do this, it is necessary for the foundation formulation to have slip qualities that are sufficient to allow good handling, especially for the purpose of covering the entire surface to be made up. It is this that especially makes it possible in the end to have a uniform makeup effect, without marks or demarcations.
- More particularly, the inventors have demonstrated that the presence of an effective amount of polymethyl methacrylate, also known as PMMA, in certain compositions of foundation type are specifically advantageous in these terms.
- Polymethyl methacrylates are generally in the form of hollow white spherical particles generally of the order of a micrometre in size. These particles have the particular feature of having high water or oil adsorption capacity, which is particularly advantageous in cosmetic formulations. Thus, in oil-based cosmetic compositions, by partially adsorbing these oils, they give the corresponding composition a dry and powdery feel. Moreover, in formulations of lipstick base type, they allow 10% to 30% of water to be incorporated. These hollow spherical particles of polymethyl methacrylate have thus already been proposed for encapsulation or reservoir purposes, in dry oils, water-based lipsticks and free or compacted powders with a high oil or water content.
- The inventors have found, unexpectedly, that the presence of polymethyl methacrylate can also be a deciding factor for optimizing the properties of cosmetic compositions such as, especially, “fluid” foundations, in terms of application.
- Consequently, according to a first aspect, the main subject of the present invention is a fluid cosmetic composition in the form of a water-in-oil emulsion comprising a liquid fatty phase, an aqueous phase and a dimethicone copolyol, characterized in that it comprises solid particles of polymethyl methacrylate and in that the liquid fatty phase comprises isododecane, the said composition being free of cyclotetrasiloxane.
- According to a second aspect, the present invention is also directed towards a fluid cosmetic composition in the form of a water-in-oil emulsion comprising a liquid fatty phase, an aqueous phase, a dimethicone copolyol and a C8-C22 alkyl dimethicone copolyol, characterized in that it comprises solid particles of polymethyl methacrylate and in that the liquid fatty phase comprises a volatile hydrocarbon-based oil, the the said composition being free of cyclotetrasiloxane.
- According to another of its aspects, a subject of the present invention is also a process for making up the skin, characterized in that it comprises the application to the skin of at least one composition in accordance with the invention.
- Polymethyl Methacrylates
- The polymethyl methacrylates are generally in the form of hollow or solid white spherical particles generally with a micrometre-scale number-average size, in particular ranging from 5 to 20 microns and generally ranging from 7 to 15 microns. The expression “number-average size” denotes the size given by the statistical particle size distribution to half of the population, referred to as D50.
- It is also possible to characterize these polymethyl methacrylate particles by their density, which can vary especially as a function of the size of the spherical cavity of the said particles.
- In the context of the present invention, this density is assessed according to the following protocol, referred to as the packed density:
- m=40 g of powder is poured into a measuring cylinder; the measuring cylinder is then placed on a STAV 2003 machine from STAMPF VOLUMETER; the measuring cylinder is then subjected to 1500 packing motions; the final volume Vf of packed powder is then measured directly on the measuring cylinder. The packed density is determined by the ratio m/vf, in this instance 40/Vf (Vf being expressed in cm3 and m in g).
- In particular, the density of the polymethyl methacrylate particles that may be used according to the invention may range from 0.3 to 0.95, especially from 0.45 to 0.80 and more particularly from 0.5 to 0.75.
- According to one particular embodiment of the invention, the composition according to the invention comprises at least two polymethyl methacrylates that differ in their density.
- According to this variant of the invention, the composition may comprise two types of polymethyl methacrylate particle, the difference in density of which is at least 0.12, especially at least 0.15, in particular at least 0.18 and more particularly at least 0.22.
- By way of illustration, a composition according to the invention can combine a polymethyl methacrylate of density 0.5 with a second polymethyl methacrylate of density 0.75.
- The polymethyl methacrylates of different densities may be combined in weight proportions ranging, respectively, from 40% to 60%, especially from 45% to 55% and in particular from 48% to 52% by weight relative to the total weight of polymethyl methacrylates, or even in a weight ratio of 1.
- Without wishing to be bound to any theory, it appears that the polymethyl methacrylate powders with a density of greater than 0.5 are more particularly advantageous for prolonging the slip qualities of the composition over time. As regards the polymethyl methacrylate particles with a density of less than or equal to 0.5, these would appear to be more advantageous in terms of handling of the the said composition. In other words, the foundation can be put on more quickly.
- According to one particular variant of the invention, the content of polymethyl methacrylate of higher density is predominant over the content of polymethyl methacrylate of lower density.
- In particular, the polymethyl methacrylate particles of higher density may be solid particles, and the polymethyl methacrylate particles of lower density may be hollow particles.
- The polymethyl methacrylates according to the invention may be present in the composition in an amount ranging from 1% to 10% by weight, in particular from 2% to 7% and more particularly from 2.5% to 5.5% by weight relative to the total weight of the composition.

The pigments may represent from 0.1% to 40% by weight, especially from 1% to 35% by weight and in particular from 2% to 25% by weight relative to the total weight of the composition.
- The nacreous pigments may be chosen from white nacreous pigments such as mica coated with titanium or with bismuth oxychloride, coloured nacreous pigments such as titanium mica with iron oxides, titanium mica especially with ferric blue or with chromium oxide, titanium mica with an organic pigment of the abovementioned type and also nacreous pigments based on bismuth oxychloride. They may represent from 0.1% to 20% by weight and in particular from 0.1% to 15% by weight relative to the total weight of the composition.
- Advantageously, the emulsion according to the invention comprises hydrophobic-coated pigments. The hydrophobic-coated pigments are pigments (such as those mentioned above) that are surface-treated with a hydrophobic agent to make them compatible with the fatty phase of the emulsion, especially so that they have good wettability with the oils of the fatty phase, such that these treated pigments are satisfactorily dispersed in the fatty phase.
- The hydrophobic treatment agent may be chosen from silicones, for instance methicones, dimethicones or perfluoroalkylsilanes; fatty acids, for instance stearic acid; metal soaps, for instance aluminium dimyristate, the aluminium salt of hydrogenated tallow glutamate, perfluoroalkyl phosphates, perfluoroalkylsilanes, perfluoroalkyl-silazanes, polyhexafluoropropylene oxides, polyorganosiloxanes comprising perfluoroalkyl perfluoropolyether groups, and amino acids; N-acylamino acids or salts thereof; lecithin, isopropyl triisostearyl titanate, and mixtures thereof.
- The N-acylamino acids may comprise an acyl group containing from 8 to 22 carbon atoms, for instance a 2-ethylhexanoyl, caproyl, lauroyl, myristoyl, palmitoyl, stearoyl or cocoyl group. The salts of these compounds may be the aluminium, magnesium, calcium, zirconium, zinc, sodium or potassium salts. The amino acid may be, for example, lysine, glutamic acid or alanine.
- The term “alkyl” mentioned in the hydrophobic agents mentioned above especially denotes an alkyl group containing from 1 to 30 carbon atoms and preferably containing from 5 to 16 carbon atoms.
- Hydrophobic-treated pigments are especially described in patent application EP-A-1 086 683.
- Rheology
- Advantageously, the composition according to the invention may have a viscosity, measured at 25° C., at a shear rate of 200 min−1(200 rpm, i.e. a frequency of 50 Hz), ranging from 0.15 to 0.6 Pa.s (1.5 to 6 poises) and especially ranging from 0.25 to 0.45 Pa.s (2.5 to 4.5 poises). Such a viscosity allows easy application of the emulsion and allows a homogeneous, uniform, mark-free makeup effect to be obtained. The viscosity is measured at 25° C. using a CONTRAVES TV viscometer equipped with a No. 2 spindle, the measurement being performed after spinning the spindle for 10 minutes (after which time stabilization of the viscosity and of the spin speed of the spindle are observed), at a shear rate of 200 min−1.
- Additives
- The composition of the invention may also comprise any additional additive usually used in the field under consideration, such as antioxidants, preserving agents, neutralizers, lipophilic gelling agents, aqueous-phase gelling agents, dispersants, cosmetic active agents, fragrances, free-radical scavengers, sequestering agents and film-forming agents, and mixtures thereof. These additives may be present in the composition in a proportion of from 0.0005% to 20% by weight and in particular from 0.001% to 10% by weight relative to the total weight of the composition.
- As cosmetic active agents that may be used in the invention, mention may be made of vitamins A, E, C, B3 and F, provitamins, for instance D-panthenol, calmatives, for instance α-bisabolol, aloe vera and allantoin, plant extracts or essential oils, protective or restructuring agents, for instance ceramides, “refreshing” active agents, for instance menthol and its derivatives, emollients, moisturizers, anti-wrinkle active agents, essential fatty acids and sunscreens, and mixtures thereof.
- Needless to say, a person skilled in the art will take care to select the optional additional additives and/or the amount thereof such that the advantageous properties of the composition according to the invention are not, or are not substantially, adversely affected by the envisaged addition.
- The composition according to the invention may be manufactured by the known processes generally used in cosmetics.
- The composition according to the invention may be a skin makeup composition, for instance a foundation, a concealer product, a tinted cream, a body makeup composition, and in particular a foundation to be applied to the face and/or the neck.
- The example given below is presented as a non-limiting illustration of the field of the invention.
