A light duty microemulsion liquid detergent composition, useful for removing greasy soils from surfaces with both neat and dilute forms of the detergent composition, includes a moderately water soluble complex of anionic and cationic surfactants, in which complex the anionic and cationic moieties are in essentially equivalent or equimolar proportions, an anionic detergent, a co-surfactant, an organic solvent and water. Preferably, the complex component is one in which the anionic and cationic moieties include hydrophilic portions or substituents, in addition to the complex forming portions thereof, the anionic detergent is a mixture of higher paraffin sulphonate and higher alkyl polyoxyethylene sulphate, the co-surfactant is a polypropylene glycol ether, a poly-lower alkylene glycol lower alkyl ether or a poly-lower alkylene glycol lower alkanoyl ester, and the organic solvent is a non-polar oil, such as an isoparaffin, or an oil having polar properties, such as a lower fatty acid ester or a lower fatty alcohol ester.
Also within the invention are the described complex, preferably one of equimolar proportions of sodium C₁₂₋₁₄ alkyl diethoxy ether sulphate and C₁₂₋₁₄ alkyl-bis(2-hydroxyethyl) methylammonium halide, and processes for manufacturing the liquid detergent composition and for removing grease from laundry and hard surfaces by use of such a liquid detergent composition, especially in neat form, in which latter process significantly improved cleaning results, compared to that obtained when using control detergent compositions.
一种轻型微乳液体洗涤剂组合物,可用于用纯净和稀释形式的洗涤剂组合物去除表面的油腻污垢,该组合物包括阴离子和阳离子表面活性剂的中等水溶性络合物,其中阴离子和阳离子分子以基本相等或等摩尔的比例、阴离子洗涤剂、辅助表面活性剂、有机溶剂和水组成络合物。阴离子洗涤剂是高级石蜡磺酸盐和高级烷基聚氧乙烯醚硫酸盐的混合物、助表面活性剂为聚丙二醇醚、聚低级亚烷基二醇低级烷基醚或聚低级亚烷基二醇低级烷酰酯,有机溶剂为非极性油,如异链烷烃,或具有极性的油,如低级脂肪酸酯或低级脂肪醇酯。
本发明还包括所述的复合物,最好是等摩尔比例的 C₁₂₋₁₄ 烷基二乙氧基醚硫酸钠和 C₁₂₋₁₄ 烷基双(2-羟乙基)甲基卤化铵、以及制造这种液体洗涤剂组合物和使用这种液体洗涤剂组合物(尤其是纯液)去除衣物和硬表面油脂的工艺,与使用对照洗涤剂组合物相比,后一种工艺的清洁效果显著提高。
