Abstract: Organosiloxane-oxyalkylene copolymers in which a silicon atom of at least one organosiloxane unit has attached thereto the group -X(OR)nOSiR'a(OR")3-a wherein X represents a divalent hydrocarbon group, R represents an alkylene group having 2 to 4 carbon atoms, n is an integer of at least 2, R' represents alkyl, vinyl, allyl or phenyl, R" represents alkyl or alkoxyalkyl and a has a value of 1 or 2, at least 40% of the total substituents in the copolymer being methyl. The copolymers are film forming and are particularly suitable for the treatment of textile fibres to facilitate the removal of oily stains during laundering.
