AZELAIC ACID
Azelaic Acid is a skincare ingredient used in cosmetics for its various beneficial properties. It is a dicarboxylic acid derived from grains like wheat, barley, and rye. Azelaic Acid is known for its ability to exfoliate the skin, unclog pores, and reduce the production of keratin, making it effective in treating acne and improving skin texture. Additionally, it possesses anti-inflammatory and antioxidant properties, helping to reduce redness and hyperpigmentation. Its appearance is usually a white powder, and its chemical formula is C9H16O4. Azelaic Acid is commonly found in creams, serums, and spot treatments, catering to different skin concerns and promoting a clearer, more even complexion.

What is AZELAIC ACID used for?

Azelaic Acid finds versatile uses in skincare, haircare, and cosmetics due to its numerous beneficial properties.

Origin

Azelaic Acid is produced through a chemical reaction called ozonolysis, which involves the reaction of oleic acid with ozone (O3) in the presence of a catalyst. Oleic acid is a monounsaturated fatty acid found in various vegetable oils like olive oil. During the ozonolysis process, ozone molecules break the double bond in the oleic acid molecule, resulting in the formation of azelaic acid.

What does AZELAIC ACID do in a formulation?

  • Antioxidant
  • Masking

Safety profile

Azelaic Acid is generally considered safe for topical use in skincare and cosmetics when used as directed and within recommended concentrations. It is well-tolerated by most individuals, with minimal reports of adverse reactions. However, patch testing is advisable for individuals with sensitive skin to ensure compatibility and avoid potential irritations.
