Abstract
Abstract Aqueous organopolysiloxane compositions are disclosed which are useful for durably treating substrates such as fibers, textiles and sheet-form materials. The aqueous organopolysiloxane compositions further contain an acid to adjust the pH of the composition to a non-basic value, an organic ester of titanic, zirconic or germanic acid and a surfactant to render the composition homogeneous. The organopolysiloxane contains monovalent hydrocarbon groups, aminohydrocarbon groups, hydroxy- or ether hydrocarbon groups and, optionally silicon-bonded hydroxyl and/or alkoxy groups.
