Naphthenic acid by a general formula CH O, where "n" indicates the carbon number and "z" specifies a homologous series. The "z" is equal to 0 for saturated, acyclic acids and increases to 2 in monocyclic naphthenic acids, to 4 in bicyclic naphthenic acids, to 6 in tricyclic acids, and to 8 in tetracyclic acids. Salts of naphthenic acids, called naphthenates, are widely used as hydrophobic sources of metal ions in diverse applications.Aluminium salts of naphthenic acid and palmitic acid were combined during World War II to produce napalm. The word "napalm" is derived from the words naphthenic acid and palmitic acid.
Mono- and diglycerides of fatty acids be completely excluded as being present in the product. The fatty acids from each source are chemically identical. The Vegan Society, which discourages eating animal-based foods, flags E471 as a "thing to look out for" that "can be animal OR non-animal based". Mono- and diglycerides of fatty acids Mono- and diglycerides of fatty acids (E471) refers to a food additive composed of diglycerides and monoglycerides which is used as an emulsifier. This mixture is also sometimes referred to as partial glycerides. Monoglycerides and diglycerides are both naturally present in various seed oils, however their concentration is usually low and industrial
