Description

General description

Azelaic acid (heptane-l,7-dicarboxylic acid), a dicarboxylic saturated acid, is an active component of some topical anti-acne preparations. It is reportedly identified in cosmetics and pharmaceuticals. Azelaic acid is found to suppress the growth of Propionibacterium spp. and reduce keratinization.

This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food. Find all available reference materials for compounds listed in 10/2011 here

Application

Azelaic acid may be used as an analytical reference standard for the quantification of the analyte in the following:

• Tobacco using gas chromatography coupled to mass spectrometry (GC-MS).
• Topical preparations using reversed-phase liquid chromatographic (LC) with UV-Vis detection.
