【摘要】 综述了烷基醚羧酸及其盐的近期进展情况，重点论述了醇醚羧酸及其盐（ＡＥＣ）的温和性、泡沫性能、表面张力、洗涤能力、耐硬水性能、生物降解性等。同时介绍了酚醚羧酸盐（ＡＰＥＣ）和酰胺醚羧酸盐（ＡＭＥＣ）的物化性能和应用特点。通过多项性能分析可以看出，这是一类集温和性、多功能性和生物降解性于一身的“绿色”表面活性剂新型产品，应用前景非常好。更多还原

【Abstract】 In this paper,the latest researches of Ether Carboxylic acids (ECA) and their salts are reviwed.The authors largely argument the properties of ECA,such as mildness,foaming power,hard water compatiblity,cleansing,biodegradability,et al.They also introduce the chemical and physical characteristics and applications of alkylphenol ether carboxylic and amide ether carboxylic.Based on these analysis,it can be inferred that ECA are a new kind of surfactants that offer multifunctionality,excellent mildness and good biodegradability,and they have a broad vista.更多还原
