    • A liquid detergent composition which is in liquid crystal form comprises a synthetic organic surface active agent, as the detergent component, which preferably includes one or more nonionic detergents of the ethoxylated higher fatty alcohol type, and a lesser proportion of anionic or cationic surfactant, such as sodium dialkyl sulfosuccinate or dicoco dimethyl ammonium chloride, a cosurfactant, such as tripropylene glycol butyl ether, a solvent for the soil, such as an isoparaffin of 9 to 11 carbon atoms or methyl cocoate (ester of methyl alcohol and coco acids) and water, with the water usually being the major component. Such compositions are useful for cold or room temperature cleaning of lipophilic soils, such as animal fats, from hard surfaces and from fabrics, and may be used as pre-treatments to loosen such soils from substrates to facilitate easier cleaning of dishes and laundry with conventional or the invented detergent compositions.The invention also relates to concentrated versions of the compositions, which are not in liquid crystal state but which upon dilution with water are converted to such state. Also within the invention are processes for pre-treating and cleaning materials soiled with lipophilic soils, using the invented liquid crystal detergent compositions. Additional processes of the invention are those in which liquid crystal detergent compositions are made by diluting concentrated compositions with water, and those in which lipophilic materials convert liquid crystal detergent compositions to microemulsion form, which latter processes occur during pre-spotting and cleaning applications when the liquid crystal detergent composition contacts the oily soil on surfaces being treated.
    • 液晶形式的液体洗涤剂组合物包括作为洗涤剂组分的合成有机表面活性剂,其优选包括一种或多种乙氧基化高级脂肪醇型的非离子洗涤剂和较少比例的阴离子或阳离子表面活性剂,例如 作为二烷基磺基琥珀酸二烷基酯或二氯代二甲基氯化铵,辅助表面活性剂,例如三丙二醇丁基醚,用于土壤的溶剂,例如9-11个碳原子的异链烷烃或可可酸甲酯(甲醇和可可酸的酯)和水 水通常是主要成分。 这样的组合物可用于从硬表面和织物的亲脂性污垢(例如动物脂肪)的冷或室温清洁,并且可用作预处理以从底物中松散这种污垢,以便于常规地更容易地洗涤菜肴和衣物 或本发明的洗涤剂组合物。 本发明还涉及组合物的浓缩形式,它们不是液晶状态,而是在用水稀释时转化成这种状态。 本发明还涉及使用本发明液晶洗涤剂组合物预处理和清洁用亲脂性污垢污染的材料的方法。 本发明的其它方法是通过用水稀释浓缩组合物制备液晶洗涤剂组合物的那些方法,以及其中亲油性材料将液晶洗涤剂组合物转化成微乳液形式的方法,后者的方法在预先检测和清洁应用期间发生,当 液晶洗涤剂组合物与正在处理的表面上的油性土壤接触。
