Product Informations
Azelaic acid is an organic compound with the chemical formula C9H16O4. It is a dicarboxylic acid and is naturally present in wheat, rye, and barley. Azelaic acid has several important properties and applications. Here's some information about azelaic acid:
Chemical Properties: Azelaic acid is a white crystalline solid with a molecular weight of 188.22 g/mol. It is sparingly soluble in water but soluble in organic solvents such as ethanol and aceton. It has a melting point of around 109-110°C.
Synthesis: Azelaic acid can be synthesized through different methods. One common approach involves the oxidative cleavage of oleic acid, a monounsaturated fatty acid found in vegetable oils. The oxidation reaction leads to the formation of azelaic acid, which contains nine carbon atoms and two carboxylic acid groups.
Medical Applications: Azelaic acid is primarily used in dermatology for the treatment of acne and rosacea. It has antimicrobial properties that help reduce the growth of bacteria on the skin, specifically Propionibacterium acnes, which is associated with acne. Azelaic acid also has anti-inflammatory effects and helps normalize the keratinization process, which can contribute to acne and rosacea symptoms.
Hyperpigmentation Treatment: Azelaic acid is also utilized in the treatment of hyperpigmentation disorders such as melasma and post-inflammatory hyperpigmentation. It inhibits the enzyme tyrosinase, which is involved in melanin production, leading to a reduction in skin pigmentation.
Hair Growth: Azelaic acid has been studied for its potential to promote hair growth and treat conditions like androgenetic alopecia (male-pattern baldness). It is believed to inhibit the enzyme 5-alpha reductase, which converts testosteron to dihydrotestosteron (DHT), a hormone associated with hair loss.
Safety Considerations: Azelaic acid is generally considered safe for topical use. However, some individuals may experience mild side effects such as skin irritation, itching, or dryness. It is advisable to perform a patch test before applying it to larger areas of the skin. If any severe reactions occur, it is recommended to discontinue use and consult a healthcare professional.
