A liquid dishwashing detergent composition for hand washing of dishes is described, which is mild to human hands and leaves the skin thereof noticeably smoother than conventional and control liquid dishwashing detergent compositions. The invented dishwashing composition includes 5 to 40% of synthetic organic detergent of the anionic and/or nonionic types, which preferably is a mixture of such types, 0.1 to 10% of a skin smoothening compound which is a hydrocarbon, an organic acid, an ester, an amide, an amine, a quaternary ammonium compound, or an alcohol, or any mixture thereof, each of which includes in its formula a hydrocarbyl chain of at least 25 carbon atoms, in an aqueous medium. Preferably, the detergent component is a mixture of sulfated and/or sulfonated anionic detergents, such as linear higher alkylbenzene sulfonate and higher fatty alcohol poly-lower alkoxy sulfate, or is a nonionic detergent or a mixture of a nonionic detergent, such as a condensation product of a higher fatty alcohol and lower alkylene oxide, with a sulfated and/or sulfonated anionic detergent, the skin smoothening compound includes a normal alkane of 25 to 50 carbon atoms and the proportions of synthetic organic detergent, normal alkane skin smoothening compound and aqueous medium are in the ranges of 5 to 35%, 0.2 to 5% and 50 to 80%, respectively.
Also within the invention are a process for hand washing dishes with the invented composition, dissolved in water to form a mild dishwater, which leaves the hands feeling smoother and non-greasy, and a process for manufacturing the invented composition, which latter process is important to produce such compositions having the desired hand smoothening and non-greasy characteristics.
本发明描述了一种用于手洗餐具的液体餐具洗涤剂组合物,该组合物对人的手温和,与传统的和对照的液体餐具洗涤剂组合物相比,其皮肤明显更光滑。本发明的餐具洗涤剂组合物包括 5%至 40%的阴离子和/或非离子型合成有机洗涤剂(最好是这些类型的混合物),0.1%至 10%的皮肤平滑剂化合物,这些化合物是在水介质中的碳氢化合物、有机酸、酯、酰胺、胺、季铵化合物或醇,或它们的任何混合物,其中每一种在其式中都包括至少 25 个碳原子的烃基链。洗涤剂成分最好是硫酸盐化和/或磺酸盐化阴离子洗涤剂的混合物,如线型高烷基苯磺酸盐和高脂 肪醇聚低烷氧基硫酸盐,或者是非离子洗涤剂或非离子洗涤剂的混合物,如高脂肪醇和低环氧亚 烷的缩合产物、与硫酸盐化和/或磺酸盐化的阴离子洗涤剂,皮肤平滑剂化合物包括 25 至 50 个碳原子的普通烷烃,合成有机洗涤剂、普通烷烃皮肤平滑剂化合物和水介质的比例范围分别为 5 至 35%、0.2至5%和50至80%。
本发明还包括一种用本发明的组合物洗手洗碗的工艺,将本发明的组合物溶解在水中形成温和的洗碗水,使手感觉更光滑、不油腻;以及一种制造本发明组合物的工艺,后一种工艺对于生产具有所需的手部光滑和不油腻特性的这种组合物非常重要。
