Salicylic Acid BP
Salicylic Acid BP is a white, crystalline organic acid widely used in pharmaceuticals, cosmetics, and industrial applications. Known for its keratolytic, anti-inflammatory, and antiseptic properties, it is an essential ingredient in acne treatments, wart removers, and skin care formulations. The British Pharmacopoeia (BP) grade ensures high purity suitable for medicinal and cosmetic use.
Primary Uses
Pharmaceuticals
Used topically to treat acne, psoriasis, dandruff, and other skin disorders due to its keratolytic and anti-inflammatory effects.
Included in formulations for wart removal and callus treatment.
Acts as a preservative and pH adjuster in various medicinal preparations.
Cosmetics and Personal Care
Incorporated in skincare products such as exfoliants, cleansers, and anti-dandruff shampoos.
Used in formulations to reduce skin scaling and promote smooth skin texture.
Industrial Applications
Utilized in the synthesis of aspirin (acetylsalicylic acid) and other pharmaceuticals.
Employed in the manufacture of dyes, fragrances, and flavoring agents.
Secondary Uses
Food Industry
Occasionally used as a food preservative and flavoring agent (regulated and limited).
Chemical Research
Used as a reagent and standard in analytical chemistry and research laboratories.
Agriculture
Investigated for use as a plant growth regulator and disease resistance enhancer.
