Synergistic surfactant blends are disclosed. In one aspect, the blend comprises an anionic surfactant and a metathesis-based cationic surfactant comprising a quaternized derivative. The quaternized derivative is a quaternized fatty amine, quaternized fatty amidoamine, imidazoline quat, or esteramine quat made from a metathesis-derived C10-C17 monounsaturated acid or its ester derivative. Also disclosed are synergistic surfactant blends comprising a cationic surfactant and a metathesis-based anionic surfactant comprising a sulfonated derivative. The sulfonated derivative is a fatty ester sulfonate, fatty acid sulfonate, sulfoestolide, fatty amide sulfonate, sulfonated fatty ester alkoxylate, imidazoline quat sulfonate, sulfonated amidoamine oxide, or sulfonated amidoamine betaine. The synergistic blends have a negative β value or a reduced interfacial tension (IFT) when compared with an expected IFT value calculated from the individual surfactant components. Blends of the invention also exhibit surprisingly favorable solubility profiles. The surfactant blends are useful for laundry detergents, dish detergents, household or industrial cleaners, personal care products, agricultural products, building materials, oil recovery compositions, emulsion polymers, and other practical applications.
本发明公开了增效表面活性剂混合物。在一个方面,混合物包括阴离子表面活性剂和由季化合物衍生物组成的元化合物阳离子表面活性剂。季铵化衍生物是一种季铵化脂肪胺、季铵化脂肪氨基胺、咪唑啉季铵或酯胺季铵,由元合成衍生的 C10-C17 单不饱和酸或其酯衍生物制成。还公开了协同表面活性剂混合物,包括阳离子表面活性剂和由磺化衍生物组成的偏合成阴离子表面活性剂。磺化衍生物是脂肪酯磺酸盐、脂肪酸磺酸盐、磺内酯、脂肪酰胺磺酸盐、磺化脂肪酯烷氧基化物、咪唑啉季磺酸盐、磺化氨基胺氧化物或磺化氨基胺甜菜碱。与根据单个表面活性剂成分计算出的预期界面张力(IFT)值相比,增效混合物的 β 值为负值或界面张力(IFT)降低。本发明的混合物还表现出令人惊讶的良好溶解度曲线。这种表面活性剂混合物可用于洗衣粉、餐具洗涤剂、家用或工业清洁剂、个人护理产品、农用产品、建筑材料、采油组合物、乳液聚合物和其他实际应用。
