Use of aqueous solutions or dispersions of copolymers of

A cosmetic composition comprising a carboxyl-containing polysiloxane and a cosmetically acceptable auxiliary; in which the carboxyls are amidated by a compound selected from the group consisting of 2-amino-2-methyl-1-propanol, ethanolamine, morpholine and triethanolamine, and said amidation is up to 50 mol % of the carboxyls.

Use of carboxyl-containing polysiloxanes in cosmetic formulations

Process for coating and printing substrates

A process for fatliquoring, filling and hydrophobicizing leathers and furs, comprises using ene adducts of maleic anhydride with unsaturated fatty acids of from 12 to 24 carbon atoms or their C.sub.1 - to C.sub.20 -alkyl or C.sub.2 - to C.sub.20 -alkenylesters, triglycerides, amides, mono- or di(C.sub.2 - to C.sub.4 -alkanol)amides, mono- or dipolyetheramides or polyetheresters, or ene adducts partially or completely derivatized by reaction with amines or alcohols to form amides or esters, respectively.
