Abstract

A process for the production of a solid esterquat free from solvents comprising the steps of PA0 A) forming a mixture comprising PA1 (i) at least one fatty acid triethanolamine ester corresponding to formula (I) ##STR1## in which R.sup.1 CO is a saturated and/or unsaturated acyl radical containing 6 to 22 carbon atoms, R.sup.2 and R.sup.3 independently of one another represent hydrogen or have the same meaning as R.sup.1 CO, and n, m and p together stand for O or for a number of from 1 to 10; PA1 (ii) at least one fatty alcohol polyglycol ether, and PA1 (iii) at least one fatty acid partial glyceride; and PA0 B) adding an alkylating agent to the above mixture to form said solid esterquat.
