Abstract: Aqueous emulsions of organopolysiloxanes are characterised by contg. emulsifiers capable of thermal breakdown of general formula: where R is a satd. ur unsatd., straight or branched chain 10-22C hydrocarbon radical; R1, R2 and R3 are same or difft. gps which can be 1-4C alkyl, 7-10C aralkyl or 5-6C cycloalkyl, which may form a heterocyclic system with the N+; n = 0-5 and X- is a strong acid radical or a monovalent part of one. As textile H2O-repellents. When silicones were previously used as H2O emulsions, emulsifier adversely affected H2O-repellency and had to be removed by time-consuming and expensive after-treatment. The invention makes this unnecessary.
