    • 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.
    • 公开了包含C10-C12单不饱和醇的烷氧基化物,硫酸盐或醚硫酸盐的表面活性剂组合物。 烷氧基化物,硫酸盐或醚硫酸盐可衍生自十一碳烯酸或十一碳烯醇。 与其饱和类似物相比,单不饱和烷氧基化物,硫酸盐和醚硫酸盐刺激性较小,使其对个人护理,洗衣,清洁剂和其他家用应用是有价值的。 显微镜研究表明,烷氧基化物,硫酸盐和醚硫酸盐在广泛的活性水平上具有良好的相位行为,扩大了具有更大压实度的产品的机会。 当与阳离子表面活性剂组合时,烷氧基化物,硫酸盐和醚硫酸盐表现出协同作用,并且与饱和类似物相比具有改善的溶解性。 表面活性剂可用于个人护理,洗衣和清洁,乳液聚合,农产品,油田应用和特种泡沫行业。
