摘要
研究了α-磺基脂肪酸甲酯磺酸盐(α-MES)在不同水硬度条件下的去污力,并将其与家居护理产品的主力军直链烷基苯磺酸盐(LAS)进行了比较.结果显示:与LAS相比,α-MES具有更高的污垢去除指数,并且它的去污力不受水硬度的显著影响.由于α-MES的结构特点,使得分子对进入它的多价离子如Ca2+,Mg2+相对不敏感,所以添加α-MES到LAS中也显示出更好的清洁性能和更好的抗水硬度.通过对α-MES,α-MES/LAS和LAS在不同助剂剂量下洗涤性能的研究发现,添加α-MES后,洗涤产品的助剂用量能减少33%,并且不会影响去污效果.
The detergency performance ofα-sulfo fatty-methyl ester sulfonate(α-MES)under different water hardness conditions was compared against the dominant workhorse in Home Care products,linear alkylbenzene sulfonate(LAS).Results demonstrate thatα-MES has a higher soil removal index and its detergency performance is not drastically affected by water hardness,compared to that of LAS.The addition ofα-MES to LAS also shows an improved cleaning performance and better water hardness resistance,due to the structural characteristics ofα-MES,which allow the molecules to be relatively insensitive toward polyvalent ions such as Ca2+and Mg2+.The washing performance ofα-MES,α-MES/LAS,and LAS with different builders at various dosages was studied,and the results indicated that the dosage of builders in the detergent product could be reduced up to 33%with the application ofα-MES,while the detergency is not sacrificed.
