ABSTRACT:
Ester quats of the formula (1) below are described: ##STR1## where RCO is an aliphatic acyl radical having 6 to 22 carbon atoms, R.sup.1 is a methyl radical, R.sup.2 is a C.sub.1 -C.sub.6 -alkyl radical, R.sup.3 is a C.sub.3 -C.sub.6 -alkyl radical and X.sup.- is a halogen anion. They are prepared by quaternizing the corresponding carboxylic acid ethanolamine ester compound with a methyl halide in the absence or presence of solvents. The ester quats of the invention have a low melting point. Furthermore, even in high concentration they are highly water soluble and, on account of their preparation, are obtained in high purity and free from toxic contents. These ester quats can be used in many ways and are suitable, for example, for preparing solid or aqueous formulations having a high surfactant effect.
