摘要:
Cosmetic composition for topical or hair application. This composition contains, in a suitable cosmetic vehicle, a pseudo-latex consisting of particles of a film-forming radical polymer containing carboxylic acid functions, neutralized to a degree of neutralization between 10 and 80% using a polyfunctional neutralizing agent consisting either of a diamine or of the combination of a polyvalent metal salt and an inorganic or organic base, the average diameter of the said particles being between 10 and 450 nm. The composition preferably takes the form of a shampoo, a conditioner, a styling or treating lotion or gel or a hair shaping product, or the form of a make-up product such as a mascara or a nail varnish.

摘要:
A composition comprising, in a physiologically acceptable medium, at least one film-forming polymer and at least one thermal transition agent which undergoes a change of state at a transition temperature Tt chosen within a temperature range from 25° C. to 80° C., the at least one thermal transition agent being insoluble in water maintained at a temperature below the transition temperature, Tt, the at least one film-forming polymer and the at least one thermal transition agent are present in an amount which is sufficient so that the composition is capable of forming a film at the temperature of a keratinous material to which the composition is applied, wherein the film has a resistance (Rc) to hot water (40° C.) of less than or equal to 15 minutes and a resistance (Rf) to cold water (20° C.) such that Rf−Rc≧8 minutes. The invention also relates to a cosmetic care or make-up process for a keratinous material. The composition makes it possible to obtain a film which is resistant to cold water and which can be removed simply with hot water.
摘要:
Use of a composition containing at least one hydrophobic film-forming polymer and at least one thermal transition agent, in a physiologically acceptable medium, to obtain a film, wherein the composition is applied to a keratinous material, and the film may be removable with hot water. The at least one thermal transition agent being capable of undergoing a transition at a transition temperature Tt chosen within a temperature range of from 25° C. to 80° C., and being not water soluble in water maintained at a temperature below the transition temperature Tt, wherein the at least one hydrophobic film-forming polymer and at least one thermal transition agent are the same or different. The invention also relates to a composition containing, in a physiologically acceptable medium, at least 5% by weight, relative to the total weight of the composition, of at least one first hydrophobic film-forming polymer, and at least one thermal transition agent which is capable of undergoing a change of state within a transition temperature range of from 25° C. to 80° C., and being not water soluble in water maintained at a temperature below the transition temperature. The composition makes it possible to obtain a film which may be resistant to cold water and removable with hot water.
