    月桂醇聚醚硫酸酯钠(SLES) – Surfactant Intermediates product from Bio Green Oleo

    关于此产品

    月桂醇聚醚硫酸酯钠(SLES)是先将月桂醇乙氧基化再进行硫酸化制得的,在十二碳疏水链与硫酸基头基之间插入一段短的环氧乙烷单元链。其 INCI 名称为 Sodium Laureth Sulfate,各牌号以环氧乙烷单元的平均数目区分,最常见的是 2EO 或 3EO。供货形态为澄清至微浊的溶液,活性物含量 28% 或 70%。

    引入聚醚链在三个方面改变了分子性能,且都与配方相关。它使硫酸基头基远离皮肤表面并增大胶束尺寸,可测量地降低蛋白质变性,使 SLES 在相同用量下明显比 SLS 温和。它增加了亲水性,使表面活性剂在硬水中不产生沉淀,并在低温下保持澄清。它还使体系对电解质高度敏感,因此向 SLES 基料中加入氯化钠即可显著增稠,这也是洗发水和沐浴露不使用聚合物即可获得稠度的常规方法。工艺上有一点需要控制:乙氧基化可能产生痕量 1,4-二噁烷,因此各牌号需经汽提脱除,并按目标市场的限量制定规格。

    该产品用于洗发水、沐浴露、泡泡浴、洁面与洗手产品、餐具洗涤剂和家用清洁剂。

    Bio Green Oleo 按活性物含量、乙氧基化度、未硫酸化物、硫酸钠、1,4-二噁烷、pH 和色泽等指标供应 SLES 2EO 和 3EO。
