Treatment of fibres

Claim 1

A process for the treatment of keratinous fibres which comprises applying thereto from 0.1 to 10% by weight of a composition comprising the product obtained by mixing (A) a polydiorganosiloxane having terminal silicon-bonded hydroxyl radicals and a molecular weight of at least 750, at least 50% of the organic substituents in the polydiorganosiloxane being methyl radicals, any other organic substituents being monovalent hydrocarbon radicals having from 2 to 30 carbon atoms, (B) an organosilicon compound selected from the group consisting of organosilanes of the general formula RSiR' n X 3 -n wherein R represents a monovalent radical composed of carbon, hydrogen, nitrogen and, optionally, oxygen, which radical contains at least two amine groups and is attached to silicon through a silicon to carbon linkage, R' represents an alkyl radical or an aryl radical, each X represents an alkoxy radical having from 1 to 14 inclusive carbon atoms and n is 0 or 1, and partial hydrolysates and condensates of said organosilanes, and (C) from 1 to 15% by weight based on the total weight of (A) and (B) of an organic or organosilicon compound containing at least one hydroxyl radical attached to an aliphatic carbon atom, and thereafter curing the applied composition.
