Abstract

This invention concerns preparations containing partially quarternized amino-functional organopolysiloxanes and use thereof in aqueous systems on textile substrates. The preparations contain (1) 2 to 60 percent by weight of a partially quartenized amino-functional organopolysiloxane, (2) 2 to 40 percent by weight of an emulsifier, (3) 0 to 15 percent of a hydrotrope and (4) 20 to 95 percent by weight of water, with the proviso that the total nitrogen content of component (1) is in the range from 0.05 to 2.0 percent by weight, based on the overall composition of component (1).
