Use of an aqueous solution of a cationic copolymer in a detergent composition, characterized in that the cationic copolymer is formed from a cationic monomer and a nonionic monomer wherein said cationic copolymer has an average molecular weight in the range 30,000 to 300,000 and the aqueous solution has a concentration of 20 to 50 % weight and a viscosity of less than 10,000 cP at 25 ~C. The invention also claims cosmetic compositions obtained from the aqueous solution of a cationic copolymer.
L'invention concerne l'utilisation d'une solution aqueuse d'un copolymère cationique dans une composition détergente, caractérisée en ce que le copolymère cationique est formé à partir d'un monomère cationique et un monomère non ionique, ce copolymère cationique possédant un poids moléculaire moyen compris entre 30'000 et 300'000 et la solution aqueuse ayant une concentration comprise entre 20 et 50 % en poids et une viscosité inférieure à 10'000 cP à 25 ·C. Cette invention concerne également des compositions cosmétiques obtenues à partir de la solution aqueuse d'un copolymère cationique.
