We own 5 sets of most advanced HPLC testing equipment and over 15 years OEM/ODM expertise, supplying dependable quality to cosmetic formulators, pharmaceutical compounders and nutraceutical companies all over the world. Every batch is thoroughly tested from the source through to final packaging, to guarantee a continuous supply and reliable performance on your production line.
What is Salicylic Acid Powder Bulk?
The product is a high purity white crystalline powder of industrial grade beta-hydroxy acid (BHA) primarily produced using the Kolbe-Schmitt procedure. This is done by heating sodium phenolate with carbon dioxide under pressure (approximately 100 atmospheres) at a high temperature (about 125° C.) and then acidifying to crystalline crystals of salicylic acid.
Salicylic acid is a lipophilic molecule that penetrates deep into the sebaceous follicles and is a key active ingredient for B2B customers who are developing acne treatments, exfoliating cleansers and anti-inflammatory skincare products. Purchasing the powder form in bulk offers manufacturers the advantage of precise control of concentration levels (typically 0.5–2% in end products), reduced transportation costs compared to pre-formulated solutions and consistent batch-to-batch quality in large volume production environments.
Our bulk supply is able to satisfy major industrial requirements; ie stable crystalline structure resistant to oxidative degradation, very low level of impurities that can induce skin sensitisation, and particle size uniformity for easy dispersion in a range of formulation bases.

Manufacturing Process & Quality Control
Our production employs the industrial-standard Kolbe-Schmitt synthesis route. Sodium phenolate reacts with CO₂ under controlled high-pressure conditions to form sodium salicylate, which is then acidified using sulfuric acid to crystallize pure salicylic acid.
Throughout manufacturing, our 5 HPLC systems monitor purity at multiple checkpoints. We conduct real-time heavy metal screening, microbial testing, and particle size analysis to ensure compliance with USP/EP pharmacopeial standards.
Every batch includes a full Certificate of Analysis. Third-party testing services are available upon request for customers requiring additional regulatory documentation.
Key Benefits in Commercial Applications
For Cosmetic Formulators
Pore-refining serums, acne spot treatments and oil-control toners: The active ingredient is the key. The keratolytic effect dissolves the intercellular lipids and hence allows regulated desquamation without mechanical abrasion.
Our powder is stable at pH 3.0–4.0 in complicated emulsion systems and can withstand hydrolysis during high shear homogenisation. This guarantees the same efficiency even when paired with botanical extracts or with retinoids.
For Compounding of Pharmaceuticals
Our bulk powder is used by compounding pharmacies to manufacture personalised topical treatments for wart removal, psoriasis and callus treatment. Its high purity reduces the risk of discomfort in sensitive people .
The regulated particle size of our material (D90 ≤100 microns) provides quick dissolving in alcohol based vehicles which is important for the manufacture of compounded treatments where uniform distribution is necessary.
For manufacturing personal care
The anti-inflammatory benefits of salicylic acid are used in scalp treatments and anti-dandruff shampoos to help alleviate flaking and itching. This bulk supply enables firms to keep the concentration uniform over large batches of manufacturing and to be cost effective.
Regulatory Certifications
Our facility holds internationally recognized quality certifications:
- ISO 9001 Quality Management System Certificate – Ensures consistent process control and traceability
- HALAL Certification – Compliant for markets requiring Islamic dietary standards
- STAR-K Kosher Certification – Verified for kosher production protocols
- FDA Registration – Our facility is registered with the U.S. FDA for ingredient manufacturing
All documentation is available for regulatory review and customs clearance.
Storage Stability & Handling Recommendations
Store Salicylic Acid Powder Bulk in a cool, dry place around 15-25°C, away from direct sunlight. The crystalline structure is stable for 36 months in sealed, moisture-proof containers.
Avoid contact with strong oxidising chemicals. In formulating, add powder slowly to the oil phase or dissolve in ethanol before adding to avoid clumping.
Control pH in the heating process in large scale manufacture to avoid decarboxylation which might decrease active concentration.
