Cetpro AA is an odourless, white and highly crystalline solid with a melting point of around 109ºC. It is soluble in glycerol and glycols, but poorly soluble in water (2.1 g/l). The solubility of azelaic acid is pH dependant; the mono-and disodium salts are significantly more soluble. Also, micro-emulsions based on sorbitan esters using glycerol and lauryl alcohol as co-surfactants help to enable the solubilisation of azelaic acid. 

Applications:

Cetpro AA is an active ingredient for anti-acne, rosacea and skin whitening. 

INCI:  Azelaic Acid
