Lotion is a thick, smooth liquid preparation designed to be applied to the skin for medicinal or cosmetic purposes. It can be a liquid, usually aqueous or sometimes alcoholic preparation containing insoluble material in the form of a suspension or emulsion, intended for external application without rubbing, in such skin conditions as itching, infection, allergy, pain, or the like.

The chemicals that were used in the experiment include stearic acid, cetyl alcohol, mineral oil, glycerin, triethanolamine, preservative, and fragrance. It is showed that steric acid serves as a lubricant for the lotion or to prevent the oxidation. The cetyl alcohol acts as a skin softener. The mineral oil serves as lubricant laxative.
