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.
