温和表面活性剂(英文)

Mild Surfactants

尽管目前表面活性剂的品种有数千种之多 ,但已通过试验证实可用于个人保护用品配方中的表面活性剂却寥寥可数。主要原因是去污好的表面活性剂并非都温和 ,反之亦然。综述了目前已用于个人保护用品中的主要表面活性剂 ,并按a -SAA、n -SAA、z -SAA和c -SAA分类说明了这些表面活性剂在配方中的功能及其温和程度。同时阐述了影响表面活性剂刺激性 /温和程度的因素 ,以及如何改善a -SAA的温和性。

WT5”BZ]:Although there are many surfactants being promoted in the market for mildness,number of surfactants actually being used in personal care products is not so large as the number being promoted,due to strict legal requirements for thorough test prior to approval for use in these products.The paper summarized the most surfactants used in personal care products,which are classified to a-SAA,n-SAA,z-SAA and c-SAA,described the functionts in formulae and mildness of these select surfactants.In the paper the authors discuss what makes a surfactant irritating mild and how to improve mildness of a-SAA.
