Organopolysiloxanes which contain a fragrance alcohol Y-OH bonded via a betaine ester group having the structure -N<SUP>+</SUP>R<SUP>1</SUP>R<SUP>2</SUP>-CH<SUB>2</SUB>-C(O)OY, cleave off the fragrance alcohol under acid conditions and are resistant to hydrolysis in the neutral and weakly basic range. The organopolysiloxanes adhere to textile fibres, skin or hair and are suitable as perfume components for textile treatment agents and personal care products.
