Abstract: Cosmetic compositions for make-up containing acrylic comb copolymers having the advantage of increasing the intensity of the color produced by these compositions when they are applied to the skin or to keratin derivatives such as the hair or the eyelashes. Not only are the aesthetic properties conferred by these compositions thus improved, but their useful life is also increased, since they allow access to the desired shade (and good intensity) right from the first application.

Abstract: Utilisation of (meth)acrylic comb copolymers with side chains of the hydroxy and alkoxy polyalkylene glycol type in which are present both ethylene oxide and propylene oxide links. These copolymers give a styling effect and an elimination of rinsing. The invention also relates to a cosmetic formulation containing such structures as well as a hair treatment process based on this formulation.

Abstract: Process for thickening a composition, through the use of a direct emulsion in water, which is alkali-swellable, of a polymer of the ASE or HASE type, which is both rich in acrylic acid and which has a certain quantity of AMPS. The use of such emulsions simultaneously allows there to be no obligation to use surfactants and organic solvents other than water, and allows the thickening phenomenon to be activated for pHs of less than 7: this latter characteristic is particularly advantageous for formulations intended to be used in contact with skin.
