A composition containing, 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 the range from 25° C. to 80° C., the at least one thermal transition agent being not water soluble 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, wherein the film has a water uptake (Rc) for hot water maintained at 40° C. of at least 15%, and a water uptake (Rf) for cold water maintained at 20° C. wherein Rc−Rf≧3%, and wherein the at least one film-forming polymer and the at least one thermal transition agent are the same or different. 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 may be resistant to cold water and removable with hot water.

摘要:
On the rotor, between each blade integral with its folding mount and the member for linking with the hub, an electrical connecting cable comprises a first section of which one part is held, in any position of the blade about the folding axis, above the mount and the radially outer end of the link member on which the mount pivots, in an off-centered position with respect to the folding axis and on the side towards which the blade is designed to be folded. This holding is provided by a cable support tied to the folding pivot and on which an arm, receiving the held part of this section of cable, is mounted in cantilever manner on the folding side.

摘要:
The present invention is directed to a cosmetic composition comprising at least one neutralized ionic film-forming polymer, water and least one polar organic solvent which is at least partially water-miscible and of higher boiling point than the boiling point of water, wherein the film-forming polymer is insoluble in water and is soluble in the organic solvent when it is in a non-neutralized state. In addition the neutralized film-forming polymer is soluble in the mixture of organic solvent and water and further wherein the mixture of neutralized polymer, organic solvent and water is a single phase.
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.
