Abstract
A composition comprising a silicone having at least one polyether functionality and at least one amino functionality, and an alkyl ether carboxylate of the general formula:R7O(C2H4O)t(CH(CH3)CH2O)qLkCOOAwherein R7 is a monovalent hydrocarbon moiety of comprising about four to about 22 carbon atoms, t is 0 to about 20, q is 0 to about 10, L is a divalent hydrocarbon group of 1 to about 6 carbon atoms and k is 0 or 1, provided that the sum of t and q is greater than or equal to 1. There is also provided a method for treating a textile using the above composition, which method results in decreased silicone oil spotting, especially at elevated temperatures and pH.
