Description

一种组合物、制备方法和用途
本申请要求于2022年02月11日提交中国专利局、申请号为202210130294.4、申请名称为“一种组合物、制备方法和用途”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及日化材料领域，具体为一种组合物、制备方法和用途。
背景技术
清洁剂仅仅清洁和去污是远远不够的，消费者希望购买外观稠厚的清洁剂。这是因为，消费者认为稠厚的清洁剂是清洁效果好、有效物含量更高的产品。同时，稠厚的清洁剂容易装入包装容器中，有利于降低包装成本，便于使用和携带。
目前清洁剂中普遍使用酰基烷基羟乙基磺酸酯等表面活性剂，含有该种表面活性剂的清洁剂具有良好的增稠效果，但是稠厚的清洁剂往往会黏附在皮肤和毛发表面不易涂抹开，影响起泡速度和发泡效果。而起泡速度和发泡效果是消费者评价清洁剂产品质量的重要因素之一。
现阶段，为了同时改善清洁剂的增稠效果和发泡性能，通常采用具有不同分子式或者同分异构体的酰基烷基羟乙基磺酸盐酯复配得到的表面活性剂组合物，以改善清洁剂的增稠效果和发泡性能。例如专利文献CN1906288B(CN200480040682.3)公开了可用于消费品中的酰基烷基羟乙基磺酸盐酯。通过在酯化反应条件下使一种或多种羧酸与一种或多种烷基取代的羟烷基磺酸盐反应，产生酰基烷基羟乙基磺酸盐酯。通过使亚硫酸氢盐与一种或多种环氧烷反应制备产生该酯时用作原料的烷基取代的羟烷基磺酸盐。其说明书记载的一种组合物产品中，包含互为异构体的酰基烷基羟乙基磺酸盐酯，该异构体主要在于R1和R2在乙基上的连接位置的不同。专利文献CN101466819B(CN200780021328.X)公开了一种组合物，包含互为异构体的酰基烷基羟乙基磺酸盐酯。该文件的说明书的0027 段第一异构体与第二异构体的摩尔比约为19:1-1:19。它讲的是原料甲基羟乙基磺酸钠的摩尔比，按照这个专利的实施例4，第二异构体的HO-CH2CH(CH3)-SO3X更加容易反应，所以酰基烷基羟乙基磺酸盐酯中的异构体R-COO-CH2CH(CH3)-SO3X的摩尔比要大于5％。
但是上述组合物的增稠效果、发泡性能还有待进一步提升。本方案是在对上述技术方案进行进一步深入研究后提出，本案要解决的技术问题是：如何提高组合物的发泡性能、增稠效果、耐盐性能。
