What is Salicylic Acid?
Salicylic acid (CAS: 69-72-7) is an aromatic organic acid that appears as a white to off-white crystalline powder at room temperature. It is sparingly soluble in cold water but readily soluble in hot water and organic solvents such as ethanol and diethyl ether. As the product is prone to oxidation and discoloration upon exposure to light, it must be stored away from light.
Originally discovered in willow bark, salicylic acid exfoliates dead skin cells, unclogs pores, and provides anti-inflammatory and analgesic effects. However, commercial mass production does not rely on plant extraction; instead, it utilizes the Kolbe-Schmitt synthesis process, which ensures large-scale supply, controllable purity, and batch-to-batch consistency.
Why choose Highassay?
Highassay is a specialized supplier of salicylic acid raw materials based in China. We offer salicylic acid powder in four distinct grades—Industrial, Sublimated, Cosmetic, and Pharmaceutical—tailored for applications in industry, chemical intermediates, cosmetics, and pharmaceuticals.
Production Method: The salicylic acid is synthesized via the Kolbe-Schmitt process. Phenol undergoes a high-pressure reaction followed by acidification and crystallization to yield a crude product; this is then subjected to various purification processes to produce the four finished grades. Key advantages include high purity, cost-effectiveness, and consistent batch quality.

Brief Overview of Salicylic Acid Grades
Note: Please refer to the corresponding sub-pages for detailed specifications; this page serves only to distinguish between grades and their applications.
- Industrial Grade Salicylic Acid: Serves as a fundamental raw material for downstream processing and the production of higher-grade salicylic acid.
- Sublimed Salicylic Acid: An intermediate for high-end chemical applications, primarily used for further processing into cosmetic-grade or pharmaceutical-grade salicylic acid.
- Cosmetic Grade Salicylic Acid: Suitable for personal care and skincare formulations; we also offer a cyclodextrin-encapsulated modified version.
- Pharmaceutical Grade Salicylic Acid: Suitable for the production of topical ointments, professional-grade chemical peels, and OTC active pharmaceutical ingredients (APIs).
