Abstract
Aqueous, dispersant-containing wax- and polysiloxane-dispersions (P) containing as wax PA1 (A) at least one oxidized hydrocarbon wax of needle-penetration (according to ASTM D-1321).ltoreq.4 dim and optionally PA1 (B) at least one non-oxidized hydrocarbeon wax and as polydiorganosiloxane PA1 (C) at least one optionally amino-modified and/or non-ionically modified polydiorganosiloxane with a nitrogen-content<0.6% by weight and suitably a dispersant system which is PA1 (D) a non-ionogenic, cationic or amphoteric dispersant system, are suitable as finishing agents, in particular as highly permanent softeners and sewability improving agents, especially for textile white goods.
