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.
以下是公式(1)中描述的Ester quats的中文翻译:其中RCO是具有6至22个碳原子的脂肪酰基基团,R.sup.1是甲基基团,R.sup.2是C.sub.1-C.sub.6-烷基基团,R.sup.3是C.sub.3-C.sub.6-烷基基团,X.sup.-是卤素阴离子。它们通过在溶剂存在或不存在的情况下,用甲基卤化物对应的羧酸乙醇胺酯化合物进行季铵化而制备。该发明的酯季铵化合物具有较低的熔点。此外,即使在高浓度下它们也具有高水溶性,并且由于其制备方法,其纯度高且不含有毒成分。这些酯季铵化合物可以用于许多方式,并且适用于制备具有高表面活性效果的固体或水性配方。
