几种聚合物在洗衣液中的应用探究

Study on the Application of Several Polymers in Laundry Detergent

通过循环洗涤实验和去污力测试实验,研究疏水改性丙烯酸聚合物、丙烯酸/苯乙烯共聚物、聚乙烯亚胺乙氧基化物和乙氧基化多胺共四种聚合物分别添加在洗衣液配方中,对洗衣液的抗再沉积性能和去污力性能的影响。实验结果表明,无论是在普通洗衣液还是在三倍浓缩洗衣液体系中,选择合适的聚合物,既能提高洗衣液抗再沉积性能,又能提高皮脂去污力。

The effects of hydrophobic modified acrylic polymer,acrylic acid/styrene copolymer,polyethyleneimine ethoxylate and ethoxylated polyamine on the anti-redeposition and detergencyproperties of laundry detergent were studied through cyclic washing experiment and detergencytest.The experiment shows that,whether in the ordinary laundry liquid or in the triple concentrated laundry liquid system,adding appropriate polymers can not only improve the anti-redeposition performance of the laundry liquid formula,but also improve the sebum detergencyability of the formula.
