Esterquats, which are quaternary ammonium compounds having two long (C(16)-C(18)) fatty acid chains with 2 weak ester linkages, represent a new generation of fabric softening agents, having replaced the dialkyldimethylammonium salts (e.g. DTDMAC and DSDMAC). The inclusion of ester linkages into the aliphatic chains has significantly improved the kinetics of biodegradation of the cationic surfactants, lowering the environmental exposure levels. This new generation of fabric softening agents combines a good environmental profile with the structural features required for an effective fabric conditioner. The present paper reviews the synthesis, types, actives combines a good environmental profile with the structural features required for a properties and applications of esterquats.
酯基季铵盐是具有两个长（C(16)-C(18)）脂肪酸链和两个弱酯键的季铵化合物，代表了新一代织物柔软剂，已取代了二烷基二甲基铵盐（如DTDMAC和DSDMAC）。在脂肪链中引入酯键显著改善了阳离子表面活性剂的生物降解动力学，降低了环境暴露水平。这种新一代织物柔软剂将良好的环境特性与有效织物调理剂所需的结构特征结合在一起。本文综述了酯基季铵盐的合成、类型、活性、性能及应用。
