    十二烷基硫酸钠(SLS) – Surfactant Intermediates product from Bio Green Oleo

    关于此产品

    十二烷基硫酸钠,商业上称为月桂醇硫酸钠或 SLS,是一种阴离子表面活性剂,由椰子油或棕榈仁油衍生的月桂醇经硫酸化并用氢氧化钠中和制得。其 CAS 号为 151-21-3,INCI 名称为 Sodium Lauryl Sulfate,供货形态为针状、粉状或膏状,也可提供 28% 至 30% 的溶液。

    其效能源于简单的分子结构:十二个碳原子的疏水链连接一个完全电离的小硫酸基头基。该链长恰好是表面活性剂向新生成的气-水界面迁移最快的链长,而硫酸基头基无论 pH 高低都带有强而永久的负电荷。两者结合赋予其极高的发泡力,以及对油脂和蛋白质类污垢的强力去除能力。同样的性质也解释了它刺激性强的名声:SLS 易使皮肤蛋白质变性,正因如此被用作皮肤刺激性试验的标准阳性对照。它还对硬水敏感,会与钙离子生成沉淀,并在酸性条件下缓慢水解。

    该产品用于牙膏、洗发水、工业及家用清洁剂、洗车与脱脂产品,用作消防和矿业的发泡剂,用于乳液聚合,并作为蛋白质电泳的实验室试剂。

    Bio Green Oleo 按活性物含量、未硫酸化物、硫酸钠、pH、色泽和水分等指标供应符合规格的月桂醇硫酸钠。
