ABSTRACT OF THE DISCLOSURE: 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 conven- tional 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.
