متن کاملNon Aqueous Titration for the Determination of Azelaic Acid: Introduction and Method Validation
Alpha-hydroxylic acids are widely used in the treatment and control of skin disorders. Azelaic acid is a naturally occuring Alpha-hydroxy acid that can be formed endogenously from long-chain dicardoxylic acids, metabolism of oleic acid or omega oxidation of mono carboxylic acids. It shows bacteriostatic and bactericidal activities against aerobic and anaerobic micro-organisms present on acne-be...
