Description
Salicylic Acid is a white or almost white crystalline powder, odorless, with a molecular weight of 138.12 and CAS number 69-72-7. It is a beta-hydroxy acid, characterized by its ability to penetrate pores and facilitate their cleansing. The product is slightly soluble in water, freely soluble in ethanol (96 percent), and sparingly soluble in methylene chloride. Standardization includes control over appearance, purity (minimum 99%), and compliance with physicochemical parameters. In manufacturing, salicylic acid is utilized for its keratolytic properties and its ability to regulate sebum secretion. For purchasers, high purity, product stability, confirmed by ISO, Kosher, Halal certifications, and adherence to cosmetic grade standards are crucial.
Applications
Applied in the cosmetic industry for the production of skincare products, cleansers, exfoliants, and hair care products.
