Surfactant compositions comprising an alkoxylate, a sulfate, or ether sulfate of a C10-C12 monounsaturated alcohol are disclosed. The alkoxylate, sulfate, or ether sulfate may derive from undecylenic acid or undecylenic alcohol. Compared with their saturated analogs, the monounsaturated alkoxylates, sulfates, and ether sulfates are less irritating, making them valuable for personal care, laundry, cleaners, and other household applications. Microscopy studies show that the alkoxylates, sulfates, and ether sulfates have favorable phase behavior over a wide range of actives levels, expanding opportunities for products with greater compaction. When combined with cationic surfactants, the alkoxylates, sulfates, and ether sulfates exhibit synergy, and they have improved solubility compared with their saturated analogs. The surfactants find value for the personal care, laundry and cleaning, emulsion polymerization, agricultural products, oilfield applications, and specialty foams industries.
本发明公开了由 C10-C12 单不饱和醇的烷氧基化物、硫酸盐或硫酸醚组成的表面活性剂组合物。烷氧基化物、硫酸盐或硫酸醚可以来自十一碳烯酸或十一碳烯醇。与饱和类似物相比,单不饱和烷氧基化物、硫酸盐和醚硫酸盐的刺激性较小,因此在个人护理、洗衣、清洁剂和其他家居应用中很有价值。显微镜研究表明,烷氧基化物、硫酸盐和醚硫酸盐在活性成分含量较高的情况下具有良好的相行为,从而为具有更高压缩性的产品提供了更多机会。当与阳离子表面活性剂结合使用时,烷氧基化物、硫酸盐和醚硫酸盐可发挥协同作用,与饱和类似物相比,它们的溶解度更高。这些表面活性剂在个人护理、洗衣和清洁、乳液聚合、农产品、油田应用和特种泡沫等行业中都有应用价值。
