摘要:
The present invention relates to a linear ethylenic block copolymer comprising in each block at least one ionic hydrophilic unit, which may be different from one block to another, the said ionic hydrophilic unit being present in each block in a proportion of from 2% to 100% by weight relative to the weight of the said block. The invention also relates to a cosmetic or pharmaceutical composition comprising such a copolymer, and also to a cosmetic process for making up or caring for keratin materials using the said composition.
摘要:
The present disclosure relates to linear block ethylenic copolymers that have reduced tack and thus do not leave a tacky feel, and to cosmetic and pharmaceutical compositions comprising the linear block ethylenic copolymer. Further disclosed herein is a cosmetic process for making up or caring for keratin materials, comprising the application to the keratin materials of such a composition, and also discloses herein are various cosmetic uses of such a composition. The tack of the copolymers disclosed herein is even reduced under conditions of high humidity, for example for RH values ranging from 50% to 100%.
摘要:
A composition, comprising, in a physiologically acceptable medium, at least one polymer with a highly specific ordered structure is disclosed. These compositions find a specific application in the field of caring for or making up keratinous fibers, in particular as a mascara composition for the eyelashes or for the hair.
摘要:
A composition suitable for topical application, which contains: a liquid fatty phase, at least one coloring agent, at least 2% by weight, with respect to the total weight of the composition, of a polymer which is dispersible in the liquid fatty phase, and a polymer which is soluble in the liquid fatty phase. In preferred embodiments, the composition may be provided in the form of a cast product or of a gel containing at least one coloring material, in particular pulverulent coloring material, a dispersion of polymer particles which are stabilized at the surface in a liquid fatty phase and a fat-soluble polymer of the vinylpyrrolidone copolymer type. In addition, according to the amount of polymer, it is possible to obtain, on the lips or skin, a supple film having notable transfer-free properties while being extremely comfortable. The invention also relates to the use of this dispersion in such a composition.
摘要:
A method for coating keratinous substances including applying an agent for coating keratinous substances comprising:(1) an aqueous/organic solution containing:(a) at least one non-crosslinked polymer capable of forming a deposit or a film on a keratinous substrate after drying and exhibiting a critical temperature Tc for solubility in water of the LCST or UCST type ranging from 0.degree. to 100.degree. C.; and(b) at least one total organic solvent for the polymer within the temperature range for use of the composition which is partially or completely miscible with water and more volatile than water; or(2) an aqueous solution or aqueous dispersion containing:(a) at least one non-crosslinked polymer capable of forming a deposit or a film on a keratinous substrate after drying and exhibiting a critical temperature Tc for solubility in water of the LCST or UCST type ranging from 0.degree. to 100.degree. C.; and(b) at least one surfactant and/or one hydrophilic polymer which are capable of establishing physical interactions with the non-crosslinked polymer; and cosmetic or dermatological compositions including these agents, in particular, hair form retention and/or styling products or make-up products of an aqueous nature.
摘要:
Compositions for hair shaping and/or form retention of hair comprising, in a cosmetically acceptable aqueous medium, at least one film-forming acrylic oligomer, which is soluble or dispersible in the aqueous medium, having a molecular weight, measured by steric exclusion chromatography, of less than or equal to 50,000 and with a glass transition temperature Tg ranging from 0 to 45.degree. C. preferably comprising:a) from 20 to 45% by weight of at least one residue of a monomer (A) selected from tert-butyl methacrylate, tert-butyl acrylate, and isobutyl methacrylate, relative to the total weight of the at least one film-forming acrylic oligomer;b) from 5 to 25% by weight of at least one residue of monomer (B) with ethylenic unsaturation comprising at least one carboxylic acid functional group, relative to the total weight of the at least one film-forming acrylic oligomer; andc) at least one residue of monomer (C) comprising a (C.sub.1 -C.sub.4)alkyl acrylate, in an amount sufficient to produce an oligomer having a Tg temperature ranging from 0 to 45.degree. C., wherein the at least one monomer (C) is not tert-butyl acrylate.
