油脂乙氧基化物磺酸盐在浓缩洗衣液中的应用性能研究

Study on Application Performance of Fatty Acid Ethoxylate Sulfonate in Concentrated Liquid Laundry Detergent

对比乙氧基化烷基硫酸钠(AES),测定了油脂乙氧基化物磺酸盐(SNS-80)的水溶、耐硬水和泡沫等理化性能,重点考察了SNS-80与浓缩洗衣液各组分的配伍及其在配方中的黏度调节、去污、水溶分散和泡沫等应用性能。结果表明,SNS-80比AES具有更佳的水溶和耐硬水性能,SNS-80的发泡力低于AES,是一种低泡类的表面活性剂;在浓缩洗衣液中,SNS-80与实验配方用各组分配伍性良好,具有明显的降黏功能,去污力和AES相当,添加SNS-80的产品水溶分散性好,泡沫低、易漂洗。

The physicochemical properties of fatty acid ethoxylate sulfonate （SNS-80）, such as water-solubility, hard water resistance and foaming, were studied in comparison with ethoxylated sodium alkyl sulfate （AES）. The compatibility of SNS-80 with the components of concentrated liquid laundry detergent and its application performance with viscosity adjustment, decontamination, water-dispersion and foaming were mainly studied. The results showed that SNS-80 had better water solubility and hard water resistance than AES. SNS-80 had lower foaming power than AES and was a low-foam surfactant. SNS-80 had good compatibility with components of the concentrated liquid laundry detergent, and a significant viscosity reduction function. The detergency of SNS-80 was comparable to that of AES, and the product added with SNS-80 had good water-solubility dispersion, low foaming, and easy rinsing.
