Azelaic Acid (CAS 123-99-9)

Application and positioning

A nine-carbon dicarboxylic acid with antibacterial and comedolytic activity, used at 10–20 % in topical products. It is only sparingly soluble in water and in oil, so the particle size distribution of the lot matters as much as the assay. Laurand supplies it from audited Chinese producers in kilogram to multi-hundred-kilogram lots, with the purity and microbiological documentation cosmetic formulators require.

Quality and documentation

• Batch-specific Certificate of Analysis with assay by HPLC or titration and the relevant impurity profile
• Heavy metals (Pb, As, Hg, Cd) and microbial limits to the specification agreed for cosmetic grade
• INCI name and CAS on the COA, to support your own product notification file
