Abstract:
本发明涉及一种水性液体洗衣洗涤剂组合物，其包含：(i)5‑25重量％的醇醚硫酸盐阴离子表面活性剂和直链烷基苯磺酸盐阴离子表面活性剂，其中醇醚硫酸盐与直链烷基苯磺酸盐的重量比率为0.6‑1，(ii)1‑8重量％的以下结构的烷基醚羧酸阴离子表面活性剂：R2‑(OCH2CH2)n‑OCH2‑COOH，其中：R2选自C16‑C18直链烷基链，其中n选自10‑20，并且其中烷基醚羧酸与(直链烷基苯磺酸盐表面活性剂+烷基醚硫酸盐表面活性剂)的重量比率为0.1‑1；(iii)至少60重量％的水；(iv)0‑4重量％的乙氧基化醇非离子表面活性剂，其中乙氧基化醇非离子表面活性剂与(直链烷基苯磺酸盐表面活性剂+烷基醚硫酸盐表面活性剂)的重量比率为0‑0.2；和(v)0‑1重量％的含磷化学品；以及使用该液体洗衣洗涤剂组合物处理纺织品的家用方法。
Abstract(English):

The invention relates to an aqueous liquid laundry detergent composition comprising: (i) from 5 to 25 wt.% of alcohol ether sulfate anionic surfactant and linear alkyl benzene sulfonate anionic surfactant, wherein the weight fraction of alcohol ether sulfate to linear alkyl benzene sulfonate is from 0.6 to 1, (ii) from 1 to 8 wt.% of an alkyl ether carboxylic acid anionic surfactant of the following structure: R2-(OCH2CH2)n-OCH2-COOH, wherein: R2 is selected from C16 to C18 linear alkyl chains, wherein n is selected from 10 to 20, and wherein weight fraction of alkyl ether carboxylic acid to (linear alkyl benzene sulfonate surfactant + alkyl ether sulfate surfactant) is from 0.1 to 1; (iii) at least 60 wt.% water; (iv) from 0 to 4 wt.% of an ethoxylated alcohol non-ionic surfactant, wherein the weight fraction of ethoxylated alcohol non-ionic surfactant to (linear alkyl benzene sulfonate surfactant + alkyl ether sulfate surfactant) is from 0 to 0.2; and, (v) from 0 to 1 wt.% of phosphorous containing chemicals; and to a domestic method of treating a textile using the liquid laundry detergent composition.
