Abstract
Abstract A textile processing oil, characterized by a high degree of compatibility with both oil and water, comprises: (a) between about 50 and 88 parts by weight of a mixture of alcohol ethoxylates of the formula C n H 2n+1 --O--CH 2 --CH 2 -- m OH wherein n is in the range from 9 to 11 inclusive and m has an average value in the range from 5 to 7 inclusive, (b) between about 12 and 32 parts by weight of a mixture of alcohol propoxylates of the formula C p H 2p+1 --O--CH 2 --CH 2 -- q OH wherein p is in the range from 12 to 15 inclusive and q has an average value in the range from 5 to 6 inclusive, and (c) between 0 and about 28 parts by weight of a copoly(ethoxylate propoxylate) mono C 1 to C 6 alkyl ether having an ethoxylate to propoxylate weight ratio between 30 to 70 and 5 to 95, the sum of the individual parts by weight of (a), (b), and (c) totaling 100. The compositions are particularly useful in processes for the scouring of wool.
