Azelaic Acid Powder

Azelaic Acid Powder – Premium Grade Cosmetic Raw Material for Professional Skincare Formulations

Xi'an Le-Nutra Ingredients Inc. offers pharmaceutical quality Azelaic Acid Powder with 98% 99% purity, with more than 14 years of manufacturing experience and a 60,000㎡ GMP certified production base. This nonanedioic acid powder comes with micronised particle specs (98%<50μm, min 30%<30μm) and has been tested rigorously on HPLC to guarantee consistent quality for cosmetic makers across the world. We provide consistent supply solutions for high-concentration skincare formulations, clinical dermatology applications and dermo-cosmetic brightening products to international markets with an annual manufacturing capacity of 3,000 tonnes and 98% on-time delivery performance.

What Makes Our Azelaic Acid Powder Different?

Our product is generated by improved ozonolysis of oleic acid from vegetable sources and is bio-based with pharmaceutical grade purity > 99%. This saturated dicarboxylic acid tackles important formulation problems for the cosmetic industry.

The micronization is so tiny, that it solves the frequent "gritty texture" problem that we see with many suspension-based serums. Traditional formulations suffer from crystallisation problems, while our particle size distribution enables for easy incorporation into emulsions and gel systems.

This powder is a multi-functional bioactive ingredient that provides three simultaneous actions: comedolytic characteristics to clear pores, tyrosinase inhibition to regulate hyperpigmentation and anti-inflammatory activities to treat rosacea. It has a better safety profile than hydroquinone or isotretinoin alternatives and can be used in formulations that are safe for use during pregnancy and on sensitive skin.

Technical Specifications and Quality Parameters

Each batch of the product is subject to a strict testing process involving HPLC purity determination, melting point analysis and heavy metal testing. Our full documentation packages offer COA, TDS, Allergen declarations and compliance certificates (ISO, GMP, Halal, Kosher).

Professional Application Guidance for Formulators

In clinical dermatological formulations, prescription strength treatments for moderate-to-severe acne and papulopustular rosacea are typically in the 15-20% range. This range of concentrations has a better long-term safety profile compared to standard antibiotic treatments.

For dermo-cosmetic whitening products, the effective concentrations for melasma and age spots are 2-10%. For complex pigmented skin disorders, synergistic combinations work better with niacinamide or vitamin C.

These 5-alpha reductase inhibitory qualities at certain doses find use in specialised hair care solutions for the scalp treatment of androgenetic alopecia. This shows how versatile the substance is, not just for cosmetic care.

The ideal pH range of the end-product is 4.5 to 5.5. Low pH (<4.0) may increase the irritation potential whereas high pH (>6.0) converts the acid to an ionised salt form which decreases the penetration efficacy of the stratum corneum.

Solving Common Formulation Challenges

Specific dissolve procedures are required because to restrictions in water solubility. We recommend predissolving the powder in propanediol, propylene glycol or ethoxydiglycol before incorporation in oil phases or emulsions. Another option for high concentration formulations is dimethyl isosorbide.

A hot production phase (70-80°C) promotes dissolving and avoids shock precipitation. The final pH is kept slightly acidic to avoid crystallisation during storage and to guarantee that the product remains stable during its shelf life.

Careful monitoring of overall acidity levels is required in conjunction with salicylic acid or glycollic acid. Azelaic Acid Powder is gentle however stacking acids will improve exfoliation. Make it the main active for inflammation and pigmentation control. Keep BHA concentrations below 1 % for penetration enhancement.

Manufacturing Capabilities and Supply Advantages

We have 60,000㎡ production base, 6 multifunctional production lines and various extraction systems. This infrastructure enables adjustable batch sizes, from development amounts to commercial-scale orders of several tonnes and more.

Direct supply from the plant excludes the markup of intermediate links and guarantees quality control from raw materials to the final inspection. We hold more than 30 days of safety stock so we can keep global supply lines flowing.

We provide full OEM/ODM customisation service including formula formulation, specification adjustment, private labelling and packaging design. Our R&D team works together with clients to adapt purity, particle size and delivery form to the specific requirements of the application.

Global logistics alliances provide flexible shipping solutions using maritime freight, air transport or express delivery. We accept several delivery terms (EXW, FOB, CFR, CIF, DAP, DDP) and payment methods (T/T, Western Union, Paypal, Alibaba Trade Assurance) to fit the international business.

Storage and Handling Recommendations

Store in sealed containers in cool, dry, well-ventilated places, away from high temperature and high humidity settings. Manufacturing: Caking and powder flowability are affected by moisture exposure.

Reseal packaging soon after opening to reduce absorption of ambient moisture. Our usual packaging is 25 kg fibre drums with double layer food grade polyethylene bag liners to ensure product integrity during transit and storage.

For best long-term stability, keep storage temperatures below 25°C. Do not expose to direct sunlight and keep away from incompatible materials particularly strong oxidising agents.

FAQ

Q: How to remove crystallization/grittiness in final serums?

A: Ultrafine particle specs, meet micronised product. Disperse powder in ethoxydiglycol or dimethyl isosorbide before adding to oil phase or emulsion In manufacture and storage, keep the final pH slightly acid to obviate shock precipitation.

Q: Is your powder natural or man-made?

A: Our high-grade ingredient is obtained by ozonolysis of oleic acid from vegetable oils like sunflower or olive. This is bio-based origin with processing of chemical synthesis to medicinal purity levels beyond 99% that are not achievable using crude extraction procedures.

Q: What is the pH range for efficacy & stability?

A: The final product has an ideal pH of 4.5 to 5.5. A pH below 4.0 may cause skin irritation, and a pH above 6.0 ionises the acid, which prevents it from penetrating the stratum corneum and reduces its effectiveness.

Q: Can I use this with salicylic acid or glycollic acid?

A: Yes, if the formulation is well designed. Watch your overall acidity; layering exfoliants might increase the intensity of the skin's reaction. Use this as a major active for inflammation and pigmentation and lower BHA levels ( <1%) for penetration enhancement, not primary exfoliation.

Q: What are good solvents for high concentration (15-20%) formulations?

A: Very low water solubility. Recommended solvents are propylene glycol, propanediol, or ethoxydiglycol. Dimethyl isosorbide is also a good candidate. Use a heated production step (~70-80°C) to improve dissolving rate.
