Palmitic acid form of caustic soda or lye), which causes hydrolysis of the ester groups, yielding glycerol and sodium palmitate. Because it is inexpensive and adds texture and "mouth feel" to processed foods (convenience food), palmitic acid and its sodium salt find wide use in foodstuffs. Sodium palmitate is permitted as a natural additive in organic products. The aluminium salt is used as a thickening agent of napalm used in military actions. Hydrogenation of palmitic acid yields cetyl alcohol, which is used to produce detergents and cosmetics. Recently, a long-acting antipsychotic medication, paliperidone palmitate (marketed as INVEGA Sustenna), used in the treatment
Naphthenic acid The nature, occurrence, recovery and commercial uses of naphthenic acid have been reviewed. Crude oils from fields in Romania, Russia, Venezuela, the North Sea, China, and West Africa are known to be high in acidic compounds as compared to most American crude oils. The carboxylic acid content of certain California crude oils is particularly high (up to 4%) where the most abundant classes of carboxylic acids are reported to be cycloaliphatic and aromatic acids. The composition varies with the crude oil composition and the conditions during refining and oxidation. Fractions that are rich in naphthenic acids can cause corrosion damage
