摘要:
The present disclosure relates to novel ethylenic copolymers comprising from 10% to 80% by weight, of at least one monomer of polyethylene glycol (meth)acrylate type, from 20% to 90% by weight, of at least one anionic monomer, and from 0% to 70% by weight, at least one additional nonionic hydrophilic monomer. The disclosure also relates to a composition, such as cosmetic or pharmaceutical compositions, comprising the copolymers and to a method of using the same.
摘要:
The present disclosure relates to novel compositions for the cosmetic treatment of keratinous fibers, such as the hair, comprising, in a cosmetically acceptable medium, at least one dielectrophile monomer and at least one radical initiator. The disclosure also relates to processes for the treatment of keratinous fibers comprising the composition. The composition in accordance with the present disclosure may makes it possible, when it is applied to keratinous fibers, such as the hair, to obtain a sheathing exhibiting an improved resistance to external agents.
摘要:
The present invention relates to a cosmetic composition comprising, in a physiologically acceptable medium: at least one fatty phase, and at least one block copolymer of rod-coil type comprising at least one coil polymeric block structure with a variable conformation covalently bonded to at least one rod polymeric block structure with a restricted conformation.
摘要:
The present patent application relates to novel dispersions of particles of a polymer which is stabilized at the surface, in a nonaqueous medium, in which dispersions the polymer exhibits a specific glass transition temperature. Another aspect of the present disclosure is a cosmetic or pharmaceutical composition comprising the said dispersion in a cosmetically or pharmaceutically acceptable medium. The present disclosure also relates to a method for the cosmetic treatment of keratinous substances employing the presently disclosed composition.
摘要:
The invention relates to novel ethylene copolymers comprising 10-60% polyethylenglycol(meth)acrylate monomers and 40-90% substantially cationic monomer. Compositions, in particular cosmetic or pharmaceutical compositions, containing the inventive copolymers and a cosmetic treatment method using said copolymers are also disclosed.
摘要:
The invention relates to an ethylene cationic polymer comprising at least one primary, secondary or tertiary protonable amine function which is at least partially neutralised by a polymer organic acid neutralising agent which contains at least one carboxylic, sulphonic and/or phosphonic acid function. Said invention also relates to a cosmetic or pharmaceutical composition comprising said neutralised polymer in a physiologically acceptable medium, in particular, cosmetically or pharmaceutically acceptable medium. A method for cosmetically treating keratinic materials, such as a body of face skin, nails, hairs, eyebrows and/or eyelashes, consisting in applying the inventive cosmetic composition to said keratinic materials is also disclosed.
摘要:
The present invention relates to a cosmetic composition comprising, in a physiologically acceptable medium: at least one aqueous phase, at least one preservative, and at least one block copolymer of rod-coil type comprising at least one coil polymeric block structure with a variable conformation covalently bonded to at least one rod polymeric block structure with a restricted conformation.
摘要:
The present invention relates to novel ethylenic copolymers comprising: a) from 25 to 95% by weight of monomer of formula (I), comprising PEG units; b) from 4 to 50% by weight of cationic monomer or one of its salts; c) from 1 to 35% by weight of anionic monomer and/or its salts. The invention also relates to cosmetic compositions, in particular hair compositions, comprising said copolymers and to a cosmetic treatment method employing them.
摘要:
The invention relates to cosmetic compositions comprising: A) at least one anionic surfactant and at least one nonionic surfactant, and B) at least one ethylenic copolymer comprising, as a weight percentage relative to the total weight of the polymer: a) 10-60% by weight of one or more monomers of formula (I) as defined below; b) 40-90% by weight of at least one “essentially cationic” monomer chosen from: (i) one or more cationic monomers of formula (IIa), (ii) one or more amphoteric monomers of formulae (IIc) and (IId), and (iii) a mixture of one or more cationic monomers of formula (IIa) with one or more anionic monomers chosen from maleic anhydride and/or those of formula (IIb); and/or with one or more amphoteric monomers chosen from those of formulae (IIc) and (IId), c) and optionally 0-50% by weight of nonionic hydrophilic monomers, excluding methyl acrylate, methyl methacrylate and isopropyl acrylate if they are present in an amount of greater than or equal to 10% by weight. Treated hair disentangles easily during rinsing, and is soft after drying. The compositions according to the invention also allow, once the head of hair is dry, particularly advantageous shaping of the hair.
