Definitions
- the present invention relates to the implementation, in cosmetic compositions for makeup, certain comb copolymers. These have the advantage of increasing the intensity of the color produced by these compositions, when they are applied to the epidermis or keratin derivatives such as eyelashes and hair.
- the makeup compositions are products such as a foundation, an eyeshadow, a blusher, an eyeliner, a concealer product, a body makeup product, a lip makeup product, a mascara.
- this type of composition contains, in addition to a fatty phase and an aqueous phase, mineral or organic fillers and coloring agents, as well as various other optional additives such as surfactants, a film-forming polymer, etc.
- their primary purpose is to bring aesthetic properties to the surface of the body where they are applied. It may be to erase certain skin defects, to lighten or darken it, to give it one or more particular colors. In most cases, the coloration obtained, and more particularly the intensity of this coloration, is a determining factor for qualifying the quality of a product such as a foundation.
- L first coordinate in the colorimetric reference.
- CIE International Commission on Illumination
- L defines clarity, which ranges from 0 (black) to 100 (white). Therefore, for a given hue as provided by the pigments, fillers and coloring agents, the higher the L value, the more the color is attenuated since it is pulling white. Conversely, a low value of L is associated with a more pronounced coloration, that is to say more intense.
- the value of L is determined in the present Application on a cosmetic composition in the state, or on the film resulting from the application of such a composition.
- comb copolymer here designates a copolymer consisting of an essentially linear backbone and of (meth) acrylic nature, on which at least two lateral segments consisting of at least one "macromonomer” are grafted.
- macromonomer refers to a polymer or copolymer having at least one terminal group having an unsaturated ethylenic function.
- color developer agent expression The function of this copolymer will be referred to in the present invention as "color developer" agent expression. This implies that the intensity of the hue delivered by a cosmetic composition incorporating such a copolymer, at the level of the epidermis, eyelashes or hair, is increased relative to the same composition not containing such a copolymer. And we recall that in the present Application, we will always indirectly measure this intensity of the color or the hue, through the value of the parameter L (either on the cosmetic composition in the state, or after application of this in the form of a film).
- the macromonomer targeted by the present invention has the formula (I):
- R - (OP) m - (EO) n - R '(I) - m and n are integers less than 150, at least one of which is not zero,
- OP and OE respectively denote propylene oxide and ethylene oxide, R denotes a polymerizable unsaturated functional group,
- R ' represents hydrogen.
- the use of comb copolymers is already described in the field of cosmetics, in particular for hair care (EP 1 632 508 A1 and EP 2 168 991 A1).
- These 2 documents refer to structures well known to those skilled in the art, whose macromonomer differs from that of the present invention, in that R 'is necessarily an alkyl group. They highlight the particular macromonomers MPEG 550 and MPEG 2000, respectively polyethylene glycol methacrylate of average molecular weight in weight equal to 550 g / mol and 2000 g / mol.
- Such a macromonomer of formula (I) is already known and described in US Pat. No. 6,034,208.
- the manufacture of copolymers incorporating such a macromonomer is also known (see US 6,815,513, US 6,214,958, US 6,664,360). and US 7,232,875).
- other uses of these particular structures were already known: as additives in plaster formulations (EP 1 377 533 A1, EP 1 615 860 A1), cement (FR 2 939 128 A1 and FR 2 939 428 A1) or in paper coating coatings (French application not yet published and filed under the number FR 10 54575).
- Another essential characteristic of the comb copolymer according to the present invention is its weight average molar mass which must be "low", that is to say between 20 000 g / mol and 200 000 g / mol, at the opposite of other comb copolymers described in the prior art and which have a much higher mass (see in particular the documents EP 2 162 476 and EP 1 966 441, which disclose masses sometimes greater than 1 000 000 g / mol for comb copolymers incorporating a macromonomer where R 'denotes the methyl group).
- R 'denotes the methyl group nothing suggests such a choice in the state of the art, to solve the question of increasing the intensity of the color of a cosmetic composition.
- a first object of the present invention is the use as a developer agent of the color, in a cosmetic makeup composition, of at least one (meth) acrylic comb copolymer characterized in that it consists of: ) of at least one monomer which is (meth) acrylic acid
