Azelaic Acid 99.5 +%, pure, cosmetic quality

Our Azelaic acid  is a 100% natural product extracted from sunflower seeds.

Azelaic acid (nonanedioic acid, 1,7-heptanedicarboxylic acid) is a chemical compound from the homologous series of dicarboxylic acids. Their salts and esters are called azelates. As a dibasic acid, it dissociates in water in two stages of protolysis. There are three polymorphic forms, which are divided into α, β and γ. Azelaic acid can be made by oxidizing castor oil with potassium permanganate. The castor oil is first hydrolyzed to ricinoleic acid, which is then oxidized to azelaic acid. The industrial production of azelaic acid is carried out by ozonolysis of oleic acid. By alkali-melting castor oil with NaOH, sebacic acid and 2-octanol (caprylic alcohol) are industrially produced via ricinoleic acid as an intermediate.

-Usage

Azelaic acid is used as an active pharmaceutical ingredient in topical therapy for acne and rosacea. 20% cream and 15% gel preparations are used. Azelaic acid preparations require a prescription. Various diesters of azelaic acid, such as with 2-ethylhexanol (diisooctyl azelate, DIOZ), with butanol (dibutyl azelate, DBZ) or with octanol (dioctyl azelate, DOZ), are used as plasticizers for plastics.
