Description

COSMETIC COMPOSITION. NOTABLY MAKE-UP OF KERATINIC MATERIALS. IMPROVED COSMETIC PROPERTIES

The present invention relates to a cosmetic composition comprising at least two particular silicone resins, said composition being intended to be applied to keratin materials, such as skin, lips, eyelashes, eyebrows, nails, hair.

The composition according to the invention may be a make-up composition and / or a care composition for keratin materials, in particular skin and lips. The composition may be a sunscreen composition.

Make-up or skincare products of the human skin or lips such as foundations or lipsticks generally contain fatty phases such as waxes and oils, pigments and / or fillers.

These compositions, when they are applied to the skin or the lips, have the disadvantage of transferring, that is to say of being deposited at least in part, leaving traces, on certain supports with which they can be put in contact, such as a glass, a cup, a cigarette, a garment or skin. It follows a poor persistence of the applied film, requiring regular renewal of the application of the foundation composition or lipstick. Moreover, the appearance of these unacceptable traces especially on the blouse collar can exclude some women from the use of this type of makeup.

In addition, these compositions tend to migrate, that is to say, to spread inside the wrinkles and fine lines of the skin that surround the lips and eyes, resulting in an unsightly effect. It is known to improve the holding and non-transfer properties of cosmetic compositions by introducing silicone resins comprising MQ units. By way of example of documents describing such compositions, mention may be made of the patents or patent applications US Pat. No. 6,071,503, US Pat. No. 6,074,654, US Pat. No. 6,139,823, US Pat. No. 6,340,466, WO 97/17058 and WO 97/17059. . These patents disclose compositions comprising a mixture of organosiloxane resins and diorganosiloxane with a volatile oil. The deposit obtained with these compositions actually has a very good performance but quickly becomes dull. One of the expectations of consumers, especially with regard to lipsticks, is to get a satiny makeup when applied to the lips. It is therefore often necessary to add a second composition that provides shine and also reduces the stickiness of the first.

However, the "double gesture" makeup products are restrictive for the user, requiring in particular to have both compositions available and sufficient time to apply two different makeup layers. The makeup of the lips is more delicate.

In addition, in the case of solid compositions, for example in the form of a stick, the application is more catchy, that is to say less slippery, since the amount of non-volatile oil is low so as not to alter the behavior. deposit on keratin materials and in particular the lips.

There is therefore a need for cosmetic compositions, in particular lipsticks, having good properties of resistance to transfer and color retention, while providing a brilliant makeup result. The inventors have shown that it is possible to reconcile slippery application, color retention, and brightness by combining, in a cosmetic composition, containing at least one volatile oil, at least one solid silicone resin preferably comprising MQ units, and a liquid silicone resin also preferably comprising MQ units. Such a composition has cosmetic properties, in particular the application properties, improved with respect to known compositions containing a silicone resin and a volatile oil. It has been shown that by substituting a portion of the solid silicone resin with a more fluid silicone resin, it is possible to improve the sliding and the gloss while maintaining an equivalent non-transfer level. The composition of the invention also has good deposition properties, in particular color, on keratin materials. This type of cosmetic composition is stable over time (no exudation is observed) and leads, after application to the lips, to a comfortable and shiny deposit.

More specifically, one of the objects of the invention relates to a cosmetic composition comprising at least one volatile oil and at least one silicone resin solid at 25 ^° C., solubilized or dispersed in said volatile oil, the composition also containing a liquid silicone resin. According to a particular embodiment, at least one of the two silicone resins comprises at least one siloxylated silicate unit substituted with alkyl radicals and / or aralkyl radicals.

According to a preferred variant, it is the silicone resin solid at 25 ^° C. Preferably, the silicone resin liquid at 25 ^° C. is, at this temperature and at atmospheric pressure, a viscosity measured according to the ASTM D-445 standard. between 5 and 200,000 cSt.

The solid resin may be present in the composition in a content ranging from 0.5% to 25% by weight, relative to the total weight of the composition, preferably from 1% to 20% by weight.

The liquid resin may be present in the composition in a content ranging from 0.1% to 30% by weight, relative to the total weight of the composition, preferably from 0.5% to 20% by weight.

The mass ratio between the liquid resin and the solid resin may be between 1/10 and 4/1, preferably between 1/4 and 2/1, and more preferably between 1/4 and 1/1.

According to another aspect, the subject of the invention is a cosmetic composition comprising a volatile oil, and the combination of a first organosiloxane resin comprising at least one siloxysilicate unit substituted with alkyl radicals and a second organosiloxane resin comprising at least one a siloxysilicate unit substituted with alkyl and aralkyl radicals.

According to this other aspect, at least one of the resins may be a solid resin at 25 ^° C., the other then being a liquid resin at 25 ^° C.

The resins considered in the present invention may comprise units of formula: (R R ₂ R ₃ SiO) _x (SiO ₄ Z ₂ ) _Y in which: x and y are integers; and

R 1, R ₂ and R ₃ independently represent an alkyl group having from 1 to 8 carbon atoms, an aryl group or an OH group. The resin comprising at least one siloxysilicate unit substituted with alkyl radicals and aralkyl radicals may be present in a content ranging from 0.1% to 30% by weight, relative to the total weight of the composition, preferably in a certain amount. ranging from 0.5% to 20% by weight.

The mass ratio between the resin comprising at least one siloxysilicate unit substituted by alkyl radicals and aralkyl radicals and the resin comprising at least one siloxysilicate unit substituted by alkyl radicals may be between 1/10 and 4/1, preferably between 1/4 and 2/1, and more preferably between

1/4 and 1/1.

The resin comprising at least one siloxysilicate unit substituted with alkyl radicals may be present in a content ranging from 0.5% to 25% by weight, relative to the total weight of the composition, preferably in a content ranging from 1% to 20% by weight.

By way of example, the resin comprising at least one siloxysilicate unit substituted with alkyl radicals may be a trimethylsiloxysilicate resin and the resin comprising at least one siloxysilicate unit substituted by alkyl radicals and aralkyl radicals may be a phenylpropyl resin. dimethyl-siloxysilicate. The volatile oil may be present in a content ranging from 0.1% to 90% by weight, relative to the total weight of the composition, preferably ranging from 1% to 80% by weight, and preferably ranging from 5% to 70% by weight.

The compositions according to the invention may comprise a pulverulent phase comprising pigments, nacres, fillers or their mixture. They may in some embodiments be free of non-volatile oil. By "free" is meant 0% to 2%, and preferably 0% to 1%.

The compositions according to the invention may also comprise at least one polyamide polymer or copolymer chosen from polyamides-organosiloxanes.

In addition, the compositions according to the invention may comprise at least one wax, and / or at least one pasty fatty substance.

Alternatively, the compositions according to the invention are free of water. "No water" means less than 0.5% water. Preferably, the water composition does not contain water added independently of any small amounts of water present in certain raw materials of the composition. According to a particular embodiment, the composition according to the invention can be in the solid form.

For the purposes of the present invention, the term "solid" means a composition of high consistency. This is particularly the case of a stick or a gloss in pot. The hardness of a solid composition may be between 30 and 300 g, especially between 50 and 250 g and preferably between 70 and 230 g.

These values reflect the texture of a solid composition, especially able to disintegrate on keratin materials, whether it is poured into a pot or cast in the form of a stick. The hardness of a stick can be measured by the so-called "butter-cutting thread" method, which consists of cutting a stick of lipstick 8 mm in diameter and measuring the hardness at 20 ^° C., by means of a DFGHS 2 dynamometer from the company Indelco-Chatillon moving at a speed of 100 mm / minute. It is expressed as the shear force (expressed in grams) needed to cut a stick under these conditions. According to this method the hardness of a composition according to the invention ranges from 30 to 300 g, preferably from 50 to 250 g and for example from 70 to 230 g.

The subject of the invention is also, according to a third aspect, a process for making up keratin materials, in particular for the lips, comprising the application to said materials of a cosmetic composition as described above. The invention further relates, in a fourth aspect, the use of a composition as described above, to obtain a comfortable makeup, shiny, having good properties of non-transfer and color retention.

Silicone resins

The composition of the invention comprises a mixture of two different silicone resins.

According to one mode of implementation, one of the resins is liquid at 25 ⁰ C (and atmospheric pressure), while the other is solid at 25 ⁰ C (and atmospheric pressure). Advantageously, the solid organosiloxane resins used in the present invention are soluble or dispersible in the volatile oil of the composition to form homogeneous and transparent dispersions or solutions. In this, silicone resins solids according to the invention are distinguished from silicone fillers such as TOSPEARLS particles marketed by General Electric, and which are too crosslinked to be soluble in organic solvents such as toluene, xylene, isoparaffins or cyclic siloxanes. More generally, the term "resin" means a compound whose structure is three-dimensional. Thus, within the meaning of the present invention, a polydimethylsiloxane is not a silicone resin.

The resin marketed under the reference SR100O by the company General Electric may in particular be suitable as a solid silicone resin within the meaning of the present invention.

The resin marketed under the reference Silshine 151 by the company General Electric may in particular be suitable as liquid silicone resin within the meaning of the present invention.

By silicone resin, the silicone resins which are soluble or dispersible in the volatile oil of the composition are preferred. This is particularly the case of the MQ resin sold under the reference SR100O by the company General Electric, which forms in the isododecane homogeneous and transparent dispersions. While this is not the case for such charges as TOSPEARLS particles that are marketed by General Electric. According to another embodiment of the invention, the two resins are resins comprising units of formula:

(RIR ₂ R ₃ Si0) _x (Si0 _4/2) y wherein: x and y are integers; and R ₁ , R ₂ and R ₃ independently represent an alkyl group having from 1 to 8 carbon atoms, an aryl group or an OH group.

For the purposes of the invention, x and y are integers different from zero.

In particular, the first silicone resin is substituted with alkyl radicals and the second silicone resin is substituted with aralkyl radicals and alkyl radicals. The liquid siloxane resin may typically have a viscosity of between 5 and 200,000 cSt at 25 ^° C., preferably between 20 and 10,000 cSt, more preferably between 100 and 10,000 cSt at 25 ^° C.

The nomenclature of silicone resins is known under the name of "MDTQ", the resin being described as a function of the different monomeric siloxane units that it comprises, each of the letters "MDTQ" characterizing a type of unit.

The letter M represents the monofunctional unit of formula (R) ₃ SiOiZ ₂ , the silicon atom being connected to a single oxygen atom in the polymer comprising this unit.

The letter D means a Difunctional unit (R) ₂ SiO ₂ ^ in which the silicon atom is connected to two oxygen atoms

The letter T represents a trifunctional unit of formula (R) SiO _3/2.

In the units M, D, T defined above, R represents a hydrocarbon radical (especially alkyl) having 1 to 10 carbon atoms or a phenyl group or a hydroxyl group. Finally, the letter Q signifies a tetrafunctional SiO4 / _{2 unit} in which the silicon atom is bonded to four oxygen atoms, themselves linked to the rest of the polymer.

According to one embodiment of the invention, at least one of the two silicone resins comprises a unit Q. Preferably, the two silicone resins each comprise at least one Q unit.

Various silicone resins of different properties can be obtained from these different units, the properties of these polymers varying according to the type of monomers (or units), the nature and the number of the radical R, the length of the polymer chain , the degree of branching and the size of the hanging chains.

Examples of these silicone resins, there may be mentioned: which may be akylsiloxysilicates trimethylsiloxysilicates the formula [(R) ₃ SiO] _x (SiO _4/2) _y (MQ units) wherein x and y are integers ranging 50 to 80, and the R group is as defined above, - the polysilsesquioxanes of formula (RSiO _{_3/2)} _x (T units) wherein x is greater than 100 and the R group is as defined above. Polymethylsilsesquioxanes are described in US 5,246,694.
