Summary:The invention relates to a process for the preparation of a cosmetic composition obtained by kneading, at a temperature of between 100°C and 250°C, a premix comprising an ethanol-insoluble polysaccharide, an ethanol-soluble polymer and a polycarboxylic acid comprising from 4 to 8 carbon atoms, by then introducing the extrudate formed, cooled beforehand, into water or a water/ethanol mixture, and then recovering the filtrate. Application to the cosmetic treatment of the hair, in particular for the fixing or shaping of the hair. Cette invention concerne un procédé de préparation d'une composition cosmétique obtenue par malaxage, à une température comprise entre 100 et 250°C, d'un prémélange comprenant un polysaccharide insoluble dans l'éthanol, un polymère soluble dans l'éthanol et un acide polycarboxylique comprenant de 4 à 8 atomes de carbone, puis introduction de l'extrudat formé, refroidi au préalable, dans l'eau ou un mélange eau/éthanol, et récupération du filtrat. La composition cosmétique selon l'invention est appliquée au traitement cosmétique des cheveux, en particulier pour la fixation ou la mise en forme des cheveux.
