Azelaic Acid Powder 99% | Cosmetic Grade Raw Material

 

Azelaic acid powder is a high-purity dicarboxylic acid used as a functional raw material in professional skincare and cosmetic formulations. CHEN LANG BIO TECH supplies 99% azelaic acid with CAS 123-99-9 for cosmetic manufacturers, formulation laboratories, private-label producers, and ingredient distributors looking for consistent quality and reliable commercial supply.

 

Our material is supplied as a white powder with a standard specification of 99%. Each commercial batch is supported by a Certificate of Analysis (COA), while TDS and SDS documentation can be provided for technical evaluation. Standard MOQ is 25 kg, packed in a paper drum, and approximately 600 kg is currently maintained in stock for regular orders.

 

For formulators, purity is only one part of selecting the right material. Solubility, particle characteristics, dispersion behavior, formulation system, and batch consistency can all influence how azelaic acid performs during product development. For this reason, we recommend evaluating the technical specification and a representative sample before moving to commercial production.

What Is Azelaic Acid?

 

Azelaic acid, chemically known as nonanedioic acid, is a saturated nine-carbon dicarboxylic acid with the molecular formula C₉H₁₆O₄. It occurs naturally in certain biological and plant-related sources and can also be manufactured for controlled industrial applications.

 

In cosmetics, cosmetic grade azelaic acid is valued as a functional ingredient for formulations designed around clearer-looking skin, improved appearance of uneven tone, oil-prone skin care, and overall skin-texture management. Its established use in topical products has made it particularly relevant to facial creams, gels, emulsions, serums, and other targeted skincare systems.

 

For raw-material buyers, however, the chemical name alone does not define quality. The more practical questions are whether the supplied material meets the declared assay, whether its physical characteristics are appropriate for the intended formulation, and whether batch documentation is sufficient for incoming quality control.

 

That distinction is important when comparing different sources of azelaic acid 99%.

 

Why Azelaic Acid Is Used in Cosmetic Formulations

 

Azelaic acid has several properties that explain its continued use in modern skincare formulation. It is associated with the management of excess keratinization and can influence processes involved in the appearance of uneven pigmentation. It is also widely studied for its activity in skin environments associated with blemish-prone and oily skin.

 

From a cosmetic formulation perspective, these characteristics make azelaic acid for skincare formulations relevant to products positioned for:

 

•Blemish-prone and oily skin care

 

•Uneven-looking skin tone

 

•Post-blemish appearance

 

•Skin-texture refining products

 

•Clarifying facial care

 

•Targeted creams, gels and emulsions

 

The exact product positioning, concentration, claims and labeling should always be determined according to the finished formulation and the regulatory requirements of the country in which the cosmetic will be marketed.

 

This is particularly important because azelaic acid is also used in pharmaceutical products in some markets. A cosmetic raw-material specification should therefore not be interpreted as authorization for medicinal claims in a finished cosmetic.

 

Azelaic Acid Solubility: An Important Formulation Consideration

 

One of the most important technical points for formulators is azelaic acid solubility.

 

Azelaic acid has limited solubility in water at ambient temperature. Published reference data report an aqueous solubility of approximately 2.4 g/L at 20°C, although actual behavior in a finished formulation depends on temperature, solvent system, pH, other ingredients, and processing conditions.

 

This means that adding a relatively high amount of powder directly to the water phase should not automatically be expected to produce a clear solution.

 

In practice, formulation development may involve a suitable dispersion strategy, compatible solvent system, controlled processing conditions, or a suspension-based approach. The correct method depends on the intended dosage form and the sensory and stability requirements of the finished product.

 

This is also why two raw materials with the same 99% assay may behave differently during formulation if their physical characteristics differ.

 

Why Particle Size Matters

 

For poorly water-soluble cosmetic ingredients, particle characteristics can affect dispersion uniformity, sedimentation behavior, processing efficiency, and the sensory feel of the final formulation.

 

A finer azelaic acid powder may offer advantages in formulations where smooth dispersion is important, but particle size should never be evaluated independently of the complete formula. Emulsifier system, rheology modifiers, manufacturing equipment and processing sequence also affect the final result.

 

If particle size is critical to your project, please request the relevant specification before confirming a commercial order rather than relying only on assay as the purchasing criterion.

 

Quality Control and Batch Documentation

 

Consistency matters when a raw material moves from laboratory development to repeat commercial production.

 

Our quality system combines raw-material inspection, in-process controls and finished-product testing. Laboratory capabilities available across our quality platform include HPLC, GC, UV and AAS instrumentation, together with microbiological testing facilities. Production and quality management are supported by established quality systems, including ISO 9001 and ISO 22000.

 

For azelaic acid raw material, buyers can request available batch and technical documentation such as:

 

•Certificate of Analysis (COA)

 

•Technical Data Sheet (TDS)

 

•Safety Data Sheet (SDS)

 

•Product specification

 

•Available supporting quality information

 

For projects with additional requirements, such as a specific test method, particle-size requirement or destination-market documentation, send us the requirement before ordering. Our team can check the applicable batch and available documents rather than giving a generic compliance statement.

 

Cosmetic Applications of Azelaic Acid Powder

 

Azelaic acid for cosmetic formulations can be considered for several types of professional skincare products, including facial creams, emulsions, gels, serums, clarifying products, and formulas developed for oily or blemish-prone skin.

 

The formulation format matters.

 

A lightweight serum, for example, may create different technical challenges from an opaque cream or suspension system because clarity, viscosity and particle visibility become more important. A cream formulation may offer more flexibility for incorporating dispersed material, while other systems may require closer control of solvents, rheology and particle distribution.

 

For this reason, there is no single processing method that is appropriate for every azelaic acid formulation.

 

Before scale-up, formulators should conduct laboratory trials and evaluate physical stability, appearance, viscosity, pH, particle behavior, packaging compatibility and any other parameters relevant to the finished product.

 

Azelaic Acid Manufacturer and Supply Capability

 

Choosing an azelaic acid supplier involves more than comparing a quotation per kilogram. Reliable commercial sourcing also depends on batch consistency, documentation, communication, packaging, inventory and the ability to support repeat orders.

Packaging and Storage

 

Our azelaic acid powder is available in flexible packaging options to accommodate both product evaluation and commercial purchasing requirements. For smaller quantities, we offer 1–5 kg aluminum foil bag packaging, while standard bulk orders are packed in 25 kg paper drums.

 

The aluminum foil bags are securely sealed to help protect the powder from moisture and external contamination during storage and transportation. For 25 kg commercial shipments, the product is packed in a paper drum with an inner protective liner to provide additional protection during international delivery.

 

Store azelaic acid in a tightly closed container in a cool, dry and well-ventilated place, protected from moisture, direct sunlight and contamination. After opening, reseal the package promptly and follow the storage conditions specified in the current product documentation.

 

For export orders, packaging and shipping arrangements can be coordinated according to the order quantity and destination.

 

 

Azelaic Acid Powder Price and Ordering Information

 

The azelaic acid powder price depends on order quantity, current raw-material and production costs, shipping method, destination and any additional documentation requirements.
