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 to oil refinery equipment; the phenomenon of "naphthenic acid corrosion" (NAC) has therefore been well researched. Crude oils with a high content of naphthenic acids are often referred to as high total acid number (TAN) crude oils or high acid crude oil (HAC). Naphthenic acids are the major contaminant in water produced from the extraction of oil from Athabasca oil sands (AOS). Naphthenic acids have both acute and chronic toxicity to fish and other organisms. In their oft-cited article published in "Toxicological Sciences" Rogers et al. stated that "naphthenic acids are the most significant environmental contaminants resulting from petroleum extraction
