Buy Azelaic Acid CAS 123-99-9 - Quality Crystalline Powder from China Suppliers and Factory Manufacturer, Supplier

Product Name: Azelaic Acid
CAS Number: 123-99-9
Molecular Formula: C9H16O4
Molecular Structure:

Molecular Weight: 188.22 g/mol
Appearance: Crystalline Powder
Samples: Free samples are available upon request

Key Properties: With a melting point of approximately 106°C and a boiling point of 286°C (at 100 mmHg), our azelaic acid is slightly soluble in cold water (around 2.4 g/L at 20°C) and fully soluble in hot water, ethanol, propylene glycol, and ethyl acetate. This product is chemically stable, resistant to oxidation, and maintains its integrity against decomposition. Azelaic acid showcases typical reactions of dibasic carboxylic acids including salt formation and esterification.

As a leading supplier and manufacturer in China, we specialize in high-quality azelaic acid, ensuring consistent supply and reliable service. Our factory adheres to stringent quality standards to provide exceptional products to our clients worldwide.

Application

1. Dermatology / Skincare

Acne Treatment: Inhibits Cutibacterium acnes, regulates follicular keratinization, and exerts anti-inflammatory effects. Recommended by Chinese Guidelines (15% gel / 20% cream).

Whitening & Mark Fading: Selectively inhibits tyrosinase in abnormal melanocytes to fade acne marks, PIH, and melasma with lower irritation than tretinoin.

Oil Control & Soothing: Inhibits 5α-reductase to reduce sebum. Ideal for oily skin and rosacea care.

Common Dosage Forms: Gels, creams, moisturizers, serums, and masks.

10%: Daily skincare (suitable for sensitive skin)

15%: Mainstay for acne treatment

20%: Pharmaceutical grade (requires tolerance building)

2. Industrial Chemical Sector

Plasticizers: Synthesis of DOZ, Diisooctyl Azelate, etc. Used in PVC and rubber for heat/cold resistance.

Lubricants / Synthetic Oils: Components for precision instruments and aviation hydraulic fluids.

Coatings / Resins: Modified polyesters and alkyd resins for flexibility and weatherability.

3. Other Applications

Feed additives, electroplating brighteners, polymer crosslinking agents, etc.

Application Areas

1. Hair Care Industry (Core Application)

Cold Wave Lotions: Core reducing agent for permanent curling.

Straightening Creams: Cleaves disulfide bonds to soften hair for permanent straightening.

Depilatory Products: Softens body hair keratin for easy removal.

Recommended Concentration: 5%–15% (Perming); 2%–8% (Depilatory).

2. Industrial & Other Fields

Metal Corrosion Inhibition: Forms protective FeS film in high-temp environments (140–200℃).

Chemical Analysis: Masking/reducing agent for iron, aluminum, silver, and tin determination.

Material Modification: Thiolating agent for adsorption materials and functional polymers.

Electronic Cleaning: Auxiliary agent for metal surface treatment.
