Fatty Acids are the Carboxylic Acids obtained by hydrolysis of animal or vegetable Fats and Oils. Carboxylic acids having alkyl chains shorter than about seven carbon atoms are not commonly considered fatty acids. Natural fatty acids may be saturated or unsaturated and generally contain an even number of carbon atoms. Fatty Acids have the general structure R-COOH. A few chemically synthesized substances (which are rarely found in nature) are included in the listing of fatty acids in light of their usage in cosmetics. Fatty acids may be saturated or unsaturated. Palmitic Acid is a typical saturated fatty acid; Oleic Acid is a monounsaturated acid, i.e., contains one cis-double bond. The double bonds in naturally available fatty acids are almost always cis and are not conjugated. Docosahexaenoic acid is a polyunsaturated C22 fatty acid containing six double bonds. Fatty acids derived from natural triglycerides, e.g., Corn Acid, are blends of saturated and unsaturated fatty acids. Fatty acids are a common source of raw materials for the synthesis of cosmetic ingredients. They are used in cosmetics in the form of their salts, i.e., as Soaps, which are frequently formed in situ from the acid and a suitable alkali. These salts are emulsifiers and suspending agents and possess foaming characteristics which are desirable in shaving preparations and can be used in skin and hair cleaning products. Free fatty acids are used to produce superfatted soaps and as opacifiers and thickening agents. |
