Abstract: Aqueous textile treating compositions containing both nitrogen-functional organopolysiloxanes and oligomeric polyisobutylene polymers are as effective as conventional textile treating compositions containing only nitrogen-functional organopolysiloxane, and have improved resistance to yellowing, improved washfastness, and are more cost effective. Stable concentrates containing amino-functional organopolysiloxane, polyisobutylene, and a blend-stabilizing surfactant may be used to form aqueous emulsion and microemulsion fabric softener compositions.
