Composition comprising (A) a polydiorganosiloxane having molecular weight of at least 2500 and terminal －OX groups in which X is hydrogen, lower alkyl or alkoxyalkyl, at least two of the substituents in the polydiorganosiloxane containing at least two amine groups, the remainder preferably being met

Composition comprising (A) a polydiorganosiloxane having molecular weight of at least 2500 and terminal －OX groups in which X is hydrogen, lower alkyl or alkoxyalkyl, at least two of the substituents in the polydiorganosiloxane containing at least two amine groups, the remainder preferably being methyl radicals, and (B) an organosiloxane having at least 3 silicon-bonded hydrogen atoms. The compositions can be applied to keratinous fibres to render such fibres shrink resistant and are particularly suitable for application in the form of an aqueous emulsion.

A composition consisting of (A) a polydiorganosiloxane having a molecular weight of at least 2500 and terminal －OX radicals wherein X represents a hydrogen atom or an alkyl or alkoxyalkyl radical having up to 15 carbon atoms, at least two of the silicon-bonded substituents present in said polydiorganosiloxane being monovalent radicals composed of carbon, hydrogen, nitrogen and, optionally, oxygen, which radicals contain at least two amine groups and are attached to silicon through a silicon to carbon linkage, and at least 50 percent of the total substituents in said polydiorganosiloxane being methyl, radicals, any remaining substituents being monovalent hydrocarbon radicals having from 2 to 20 inclusive carbon atoms, and (B) an organosiloxane having at least three silicon-bonded hydrogen atoms in the molecule and in which the organic radicals are alkyl radicals having less than 19 carbon atoms.
