A hair relaxer includes at least one specific mercapto compound such as 2-methoxyethyl 3-mercaptopropionate, 2-mercapto-4-butanolide and 2-mercapto-4-butyrolactam. The hair relaxer can achieve an excellent effect of shaping and relaxing hair over a wide range of pH values from weak acidity to weak alkalinity. In particular, the hair relaxer displays a more superior hair shaping and relaxing performance in a weakly acidic to neutral pH range. Consequently, the hair relaxer can drastically reduce the damage to the hair and skin and can reliably perform straightening, uncurling, curling and other hair processing.
一种头发放松剂包括至少一种特定的巯基化合物,例如2-甲氧基乙基
3-巯基丙酸酯,2-巯基-4-
丁醇内酯和2-巯基-4-丁酰内酰胺。该头发放松剂可以在从弱酸性到弱碱性的广泛pH值范围内实现出色的造型和放松头发的效果。特别是,该头发放松剂在弱酸性到中性pH范围内显示出更卓越的头发造型和放松性能。因此,该头发放松剂可以大大减少对头发和皮肤的损伤,并可可靠地进行拉直、卷曲和其他头发加工。
