These applications use sodium palmitate, which is commonly obtained by saponification of palm oil. To this end, palm oil, rendered from palm trees (species Elaeis guineensis ), is treated with sodium hydroxide (in the form of caustic soda or lye), which causes hydrolysis of the ester groups, yielding glycerol and sodium palmitate.
Ascorbyl palmitate is an ester formed from ascorbic acid and palmitic acid creating a fat-soluble form of vitamin C. In addition to its use as a source of vitamin C , it is also used as an antioxidant food additive ( E number E304).
Retinyl palmitate, or vitamin A palmitate, is the ester of retinol and palmitic acid, with formula C 36 H 60 O 2. It is the most abundant form of vitamin A storage in animals. [2] An alternate spelling, retinol palmitate, which violates the -yl organic chemical naming convention for esters, is also frequently seen. [citation needed]

Hexadecyl hexadecanoate, also known as cetyl palmitate, is the ester derived from hexadecanoic acid and 1-hexadecanol. This white waxy solid is the primary constituent of spermaceti, the once highly prized wax found in the skull of sperm whales. [2] Cetyl palmitate is a component of some solid lipid nanoparticles.

Ethyl palmitate is an organic compound with the chemical formula C 18 H 36 O 2. It is a colorless solid with a wax-like odor. Chemically, ethyl palmitate is the ethyl ester of palmitic acid. Ethyl hexadecanoate is produced in aged whiskey, and is sometimes removed from the final product via chill filtering. [1]
The cyanate ion is an isomer of the much-less-stable fulminate anion, CNO − or [C − ≡N + −O −]. [ 1 ] The cyanate ion is an ambidentate ligand , forming complexes with a metal ion in which either the nitrogen or oxygen atom may be the electron-pair donor .
