Patent

CA 2273509

The invention concerns an aerosol device made up of a reservoir containing an aerosol composition consisting of a liquid phase (or juice) containing at least a fixing material in an appropriate solvent and a propellant, and means for dispensing said aerosol composition, the fixing material having a glass temperature (Tg) not less than 30 DEG C, said fixing material comprising at least an anionic grafted siliconized polymer, with polysiloxane skeleton grafted by at least an anionic hydrocarbon radical, and the device being suited for obtaining a wetting power not less than 30 mg/s. The invention also concerns a method for treating keratinous fibers which consists in applying on said keratinous fibers a composition containing a fixing material having a glass temperature (Tg) not less than 30 DEG C containing at least an anionic grafted siliconized polymer, using a device suited for obtaining a wetting power not less than 30 mg/s.

La présente invention concerne un dispositif aérosol constitué par un réservoir contenant une composition aérosol constituée d'une part par une phase liquide (ou jus) contenant au moins un matériau fixant dans un solvant approprié et d'autre pan un propulseur, et un moyen de distribution de ladite composition aérosol, le matériau fixant ayant une température de transition vitreuse (Tg) supérieure ou égale à 30 °C, ledit matériau fixant comprenant au moins un polymère siliconé greffé anionique, à squelette polysiloxanique greffé par au moins un radical hydrocarboné anionique, et le dispositif étant approprié pour obtenir un pouvoir mouillant supérieur ou égal à 30 mg/s. Elle concerne également un procédé de traitement des fibres kératiniques, dans lequel on applique sur lesdites fibres une composition comprenant un matériau fixant ayant une température de transition vitreuse (Tg) supérieure ou égale à 30 °C comprenant au moins un polymère siliconé greffé anionique, au moyen d'un dispositif approprié pour obtenir un pouvoir mouillant supérieur ou égal à 30 mg/s.
