Fabric softener active composition

摘要

The present invention is directed to compositions that are characterized by the presence of ester quats with specific characteristics that promote dispersibility at low temperature. Among the important characteristics of the ester quats are an iodine value of 65-85 and distribution of: 33-38% monoesters, 50-55% diesters and 7-12% triesters.

主权项

1. A fabric softening active composition, comprising:
a) ester quats of formula (I): wherein R1, R2 and R3 are hydrogen or a group C(O)R5;R5 is an alkyl or alkenyl group comprising 11 to 21 carbon atoms;A−is a fabric softener compatible anion;R4 is methyl or ethyl;and wherein:i) on a normalized wt % basis: 33-38% of said ester quats are monoesters; 50-55% of said ester quats are diesters; and 7-12% of said ester quats are triesters; andii) said R5 groups have an iodine value, calculated for the free fatty acid R5COOH, of from 65 to 85 and the cis to trans ratio of unsaturated bonds of said R5 groups is less than 12:1; and b) 10-25% by weight of an alcoholic solvent.
