Azelaic acid is an organic compound with the chemical formula C9H16O4 and CAS Number 123-99-9.
Esters of dicarboxylic acid are used in lubrication and plasticizers. With hexamethylenediamine, azelaic acid forms Nylon-6,9, which is a specialized plastic.
Azelaic acid is produced industrially by the ozonolysis of oleic acid. The by- product is nonanoic acid. It is produced naturally by Malassezia furfur (also known as Pityrosporum ovale), a yeast that lives on normal skin. The bacterial degradation of nonanoic acid produces azelaic acid.
- Azelaic acid is soluble in hot water, alcohol and organic solvents.
- Azelaic acid is used in the manufacture of adhesives and sealant chemicals; lubricants and lubricant additives; paint and coating additives, and plasticizers.
- Medically, Azelaic acid is used to treat mild to moderate acne, both comedonal acne and inflammatory acne.
