Overview
Azelaic acid is a saturated dicarboxylic acid naturally found in wheat, rye, and barley. It is industrially produced through the ozonolysis of oleic acid. The compound is valued for its versatility in various applications, including polymer production, lubricants, and pharmaceuticals. In recent years, azelaic acid has gained prominence in the cosmetic industry due to its skin-conditioning properties. It is also used as a precursor for manufacturing plasticizers and corrosion inhibitors, making it a crucial chemical in industrial processes.
Physical and Chemical Properties
Azelaic acid appears as a white crystalline powder with a slight odor. It has a melting point of 106-108°C and a boiling point of 286°C at 100 mmHg. The acid is soluble in hot water, alcohol, and most organic solvents but has limited solubility in cold water. Its chemical stability and non-toxic nature make it suitable for a wide range of applications. The compound is biodegradable, aligning with environmental regulations and sustainability goals in industrial use.
Main Applications
Azelaic acid is widely used in the production of polymers, where it acts as a monomer for polyesters and polyamides. It is also a key ingredient in lubricants, providing excellent thermal stability and reducing friction. In the pharmaceutical and cosmetic industries, azelaic acid is utilized for its antimicrobial and anti-inflammatory properties. It is commonly found in skincare products targeting acne and hyperpigmentation. Additionally, the acid serves as a corrosion inhibitor in metalworking fluids.
Safety and Storage
While azelaic acid is generally considered safe, it may cause mild irritation to the skin and eyes. Proper handling procedures, including the use of gloves and goggles, are recommended. The compound should be stored in a cool, dry place away from direct sunlight and moisture to maintain its stability. In case of accidental exposure, rinse affected areas with plenty of water and seek medical advice if irritation persists. Always refer to the Material Safety Data Sheet (MSDS) for detailed safety guidelines.
B2B Procurement Guide
When procuring azelaic acid for industrial use, verify the purity level, which typically ranges from 98% to 99.5%. Supplier certifications, such as ISO or GMP, are essential to ensure product quality. Bulk purchases often come with cost advantages, but storage capacity should be considered. Request samples for testing before large-scale procurement to confirm the product meets your specifications. Additionally, inquire about packaging options, as azelaic acid is commonly supplied in 25 kg bags or drums.
