摘要
氨基酸型两性表面活性剂在ｐＨ 值呈现中性时显阴离子型，在ｐＨ较低（ｐＨ＜ ４）时显阳离子型，同皮革生产主要加脂剂（阴离子型）配伍性好。而甜菜碱型、咪唑啉型和卵磷脂型则不具备这个特性。以氨基酸型两性表面活性剂（占有效物含量的８０％ 左右）为主要组份的ＡＳＦ－ Ｍ 加脂剂，具有增厚能力强和填充性能好的特点，经其加脂的革，革身柔软、丰满，绒面丝光感好。
Amino-acid ampholytic surfactant possesses the property, which is anionic in pH=7 and is ionic in pH<7,so it can be used with anionic fatliquor agent for leather-making. Bataine, imidazolium and lecithin surfactant do not possess the above property. Amino-acid ampholytic surfactant(in 80% of effective substance) is mainly composition of ASF-M fatliquor agent, so ASF-M possesses good thickening and filling properties, the resultant leather is soft, full and silky in suede side.
