Azelaic acid (AzA) is an organic compound with the formula HOOC(CH₂)₇COOH.^[3] This saturated dicarboxylic acid exists as a white powder. It is found in wheat, rye, and barley. It is a precursor to diverse industrial products including polymers and plasticizers, as well as being a component of a number of hair and skin conditioners.^[4] AzA inhibits tyrosinase.^[5]
