Detergent compositions include water soluble polymers which serve as builders, lime soap dispersants, and antiredeposition agents. The water soluble polymers, which fall into two structural classes, are especially useful in commercial heavy duty liquid detergent compositions, with which they are compatible in effective amounts. The water soluble polymers enhance several detergent properties such as antiredeposition and lime soap dispersancy with a concomittant loss in other detergent composition characteristics. Further, the polymers are compatible with enzyme containing liquid detergents. In the first structural class surfactant radicals are distributed along the polymer chain, which also includes pendent carboxyl and/or carboxylate salt radicals. An example of a polymer within this class is represented by the formula:
wherein: EO = ethylene oxide
C16-C18 = a(C16-Cl8)alkyl group or an aralkyl or alkaryl group in which the alkyl portion contains 16 to 18 carbon atoms. In the second structural class the polymers are terminated by a surfactant radical. The water soluble polymers are also effective dispersants for a number of particulate materials including kaolin clay and powdered coal, and inhibit the precipitation of calcium chloride and barium sulfate.
洗涤剂组合物包括
水溶性聚合物,可用作增效剂、
石灰皂分散剂和防再沉积剂。
水溶性聚合物分为两种结构类型,在商用重垢液体洗涤剂组合物中特别有用,因为它们能以有效的量与之相容。
水溶性聚合物可增强多种洗涤剂特性,如抗沉积和
石灰皂分散性,但同时会降低其他洗涤剂成分的特性。此外,聚合物还能与含酶液体洗涤剂相容。在第一类结构中,表面活性剂自由基沿聚合物链分布,其中还包括下垂的羧基和/或
羧酸盐自由基。该类聚合物的一个例子如式所示:
其中
EO =
环氧乙烷
C16-C18 =(C16-Cl8)烷基或芳基或烷芳基,其中烷基部分含有 16 至 18 个碳原子。在第二类结构中,聚合物以表面活性剂基团为端基。
水溶性聚合物也是许多微粒材料(包括
高岭土和煤粉)的有效分散剂,并可抑制
氯化钙和
硫酸钡的沉淀。
