Azelaic Acid Formula
Azelaic acid is a naturally occurring dicarboxylic acid whose chemical formula is C9H16O4, while its simplified molecular input line entry system (SMILES) is OC(=O)CCCCCCCC(O)=O. It exists as a white powder that is made up of 9 carbon atoms, 16 hydrogen atoms, and 4 atoms of oxygen. It is an organic compound that can be found in wheat, rye, and barley. It can be produced naturally by Malassezia furfur, which is a yeast that lives on normal skin, while industrially it is prepared by the ozonolysis of oleic acid. This acid possesses antibacterial, keratolytic, comedolytic, and anti-oxidant properties. Thus, it is used to reduce inflammation associated with acne and rosacea. It also serves as a base for several industrial products, including polymers and plasticizers.
