Abstract:
The present invention relates to a cosmetic composition comprising: —one or more keratin fiber conditioning agents; —one or more polymers of formula (I): in which: —Z1 represents a divalent group —CH2-T or -T-CH2—; T denoting an oxygen or sulfur atom, or a group chosen from the groups N(R2), N(R2)—C(O), C(O)—N(R2), S—(CO), (CO)—S, O—(CO) and (CO)—O; —Z2 represents a group OR1 or R8—CH2—NR3R4; —Z3 represents a group OR5 or R6; —p1 is equal to 1; —p2 is equal to 0 or 1; —R2 and R3, which may be identical or different, represent a hydrogen atom or a group R7; R1, R5, R6, R7 and R8, which may be identical or different, represent a C1-C6 and preferably C1-C2 alkyl group; and R4 represents a C1-C6 and preferably C1-C2 alkyl group, or a C5-C6 and preferably C6 cycloalkyl group such as cyclohexyl; R3 and R4 may optionally form, with the nitrogen atom that bears them, a 5- to 8-membered heterocycle comprising from 1 to 3 heteroatoms; —W represents a divalent polymer chain. The invention also relates to processes using this composition with or without catalysts and devices.

Abstract:
Cosmetic process for caring for and/or making up keratin materials The present invention relates to a cosmetic process for caring for and/or making up keratin materials, comprising at least the steps consisting in: (i) placing all or part of the surface of the said keratin material in contact with an effective amount of at least one emollient active agent chosen from ionic liquids based on guanidinium or dialkylimidazolium, non-volatile or sparingly volatile oils, waxes, thiol derivatives, phosphines, alkaline bases chosen from potassium hydroxide, ammonia, monoethanolamine, triethanolamine, calcium hydroxide, alkaline salts of amino acids, urea and urea derivatives, and guanidine derivatives, and mixtures thereof, (ii) placing the said surface in contact with at least one cosmetic active agent, different from the said emollient active agent, to be incorporated into the keratin at the surface of the said keratin material, and (iii) where appropriate, heating the said surface of the keratin material, steps (ii) and (iii) possibly being performed, independently of each other, prior to, simultaneously with or consecutive to step (i).
Abstract:
The present invention relates to an assembly including at least one cosmetic composition for the cosmetic treatment of eyelashes or eyebrows, and a device including a mould having two mould parts to be closed on the eyelashes, with at least one of these parts having a concave groove, which is concave towards the proximal edge of the mould, especially curvilinear, allowing the formation of a strip of composition connecting at least part of the eyelashes along the eyelid or the eyebrow arch.
Abstract:
Cosmetic treatment method for adding fibers to natural eyelashes, comprising: a) applying an adhesive composition (A) to at least part of the eyelashes, b) bringing fibers (12) borne by an applicator (10) into contact with said adhesive composition (A) present on said eyelashes, c) moving the applicator (10) away from the eyelashes, so as to release fibers (12) which adhere to said eyelashes.
Abstract:
The invention relates to a cosmetic composition comprising: (a) at least 2% by weight, relative to the total weight of the composition, of one or more compounds chosen from urea and/or urea derivatives, (b) one or more polymeric thickeners chosen from nonionic, cationic, amphoteric polymeric associative thickeners or anionic polymeric associative thickeners comprising one or more acrylic and/or methacrylic units. The invention also relates to the use of this composition for straightening keratin fibres. Finally the invention relates to a process for straightening keratin fibres.
