Azelaic acid, a saturated dicarboxylic acid with the chemical formula C9H16O4, is a multifaceted ingredient that has garnered significant attention in the cosmetic industry. Its natural occurrence in grains like wheat, rye, and barley, alongside its production via oleic acid ozonolysis, highlights its versatile origin. For cosmetic formulators, understanding the fundamental properties and broad applications of this white crystalline powder is key to harnessing its full potential.

Chemically, Azelaic acid (CAS 123-99-9) presents as a fine white powder with a molecular weight of 188.22 g/mol and a melting point around 98°C. It is slightly soluble in cold water but readily dissolves in hot water and organic solvents like ethanol and ether. This solubility profile is important for formulators when incorporating it into various product bases. Its pH is typically around 4.0-5.0, making it a gentle acid for topical application.

The therapeutic properties of Azelaic acid are extensive. Its antibacterial action targets bacteria responsible for acne, such as Propionibacterium acnes. Crucially, it possesses significant anti-inflammatory effects, helping to calm redness and irritation, which is particularly beneficial for individuals with rosacea or sensitive skin. Furthermore, Azelaic acid acts as a tyrosinase inhibitor, reducing melanin production and thus helping to fade hyperpigmentation, including melasma and post-inflammatory marks.

These properties translate into a wide array of cosmetic applications. It is a staple in anti-acne treatments, including cleansers, serums, and spot treatments. Its ability to reduce inflammation makes it ideal for soothing rosacea-prone skin, and its depigmenting effects are leveraged in skin lightening and brightening formulations. Beyond these specific concerns, Azelaic acid can also help regulate sebum production, leading to a mattifying effect and improved skin texture.

For businesses looking to source this ingredient, opting for a cosmetic grade Azelaic Acid powder with high purity (>99%) from a reliable manufacturer in China is a strategic choice. This ensures the efficacy and safety of your final products. Investigating the Azelaic acid price from various suppliers and understanding bulk purchasing options can lead to significant cost savings, allowing for more competitive product pricing in the market.
