Abstract
Quaternized esters having fabric-softening and hydrophilicizing properties are obtained by reaction of unsaturated fatty acids containing at least 40 mol-% transconfigured double bonds or esters thereof with alkanolamines and subsequent quaternization of the reaction products with alkylating agents.
Claims19
An ester quaternized with an alkylating agent wherein the ester is the reaction product of a) a monounsaturated C.sub.16-22 fatty acid or mixture of such fatty acids or an ester of the foregoing with glycerol or an aliphatic C.sub.1-4 alcohol wherein the fatty acid moieties contain at least 40 mol % trans-configuration double bonds, and b) an alkanolamine of formula I ##STR3## in which R.sup.1 and R.sup.2 are independently C.sub.2-4 hydroxyalkyl groups and R.sup.3 is either a C.sub.2-4 hydroxyalkyl group or a C.sub.1-22 straight or branched alkyl group.
A process for the preparation of a quaternized ester product comprising the steps of
- A) reacting a) a monounsaturated C.sub.16-22 fatty acid or a mixture of such fatty acids or an ester of the foregoing with glycerol or an aliphatic C.sub.1-4 alcohol wherein the fatty acid moieties contain at least 40 mol % trans-configuration double bonds, with b) an alkanolamine of formula I ##STR4## in which R.sup.1 and R.sup.2 are independently C.sub.2-4 hydroxyalkyl groups and R.sup.3 is either a C.sub.2-4 hydroxyalkyl group or a C.sub.1-22 straight or branched alkyl group;
- and
- B) reacting the product from step A) with an alkylating agent to produce the quaternized ester product.
