Abstract:
1. A cosmetic nontherapeutic treatment of a keratin material, characterized in that a cosmetic and/or dermatological composition devoid of toxicity upon skin contact comprising in a cosmetically acceptable medium, at least one polyorganosiloxane A devoid of toxicity upon skin contact containing, per molecule, at least one siloxyl unit substituted with at least one functional group V comprising at least one sterically hindered piperidinyl functional group, said polyorganosiloxanes A being characterized in that, after their preparation, the level of monomers, oligomers and polymers having a molecular mass M<1000 Daltons is reduced to a value less than 1% relative to the total molecular distribution by means of a technique allowing selective separation of the monomers, oligomers and polymers having a molecular mass M<1000 Daltons is applied to said keratin material.
