Salicylic Acid USP

Salicylic Acid USP (2-Hydroxybenzoic acid) is a high-purity, pharmaceutical-grade beta hydroxy acid (BHA) widely used in topical dermatological formulations for the treatment of acne, psoriasis, warts, and keratotic skin conditions. With well-established keratolytic, comedolytic, and antimicrobial properties, Salicylic Acid functions as both an active ingredient and an exfoliating agent across a variety of prescription and over-the-counter (OTC) products. Salicylic Acid

• Is a USP-compliant topical keratolytic agent and acne treatment active
• Is a  beta hydroxy acid that penetrates sebaceous follicles and breaks down cellular adhesion
• Is suitable for creams, gels, ointments, shampoos, cleansers, and transdermal patches
• Is effective against acne, dandruff, psoriasis, calluses, corns, and warts

Salicylic Acid works by solubilizing intercellular cement in the stratum corneum, promoting desquamation and cell turnover. It also exhibits mild bacteriostatic and fungicidal activity, contributing to its therapeutic effect in inflammatory and seborrheic skin conditions.

In pharmaceutical and personal care formulations, Salicylic Acid USP is used in:

• Topical acne treatments to reduce blackheads, whiteheads, and surface oil buildup
• Psoriasis and dandruff shampoos to remove scaling and control irritation
• Wart and corn removers at higher concentrations for keratolytic action
• Transdermal drug delivery systems as a permeation enhancer or co-active
• Cosmeceutical exfoliants and peels, often paired with other acids or retinoids

CarboMer supplies Salicylic Acid USP in both micronized and standard crystal grades, ensuring optimal dispersibility and homogeneity in emulsions, gels, and suspensions. All grades conform to USP monograph specifications for identity, assay, melting point, loss on drying, and residual solvents.

The material is packaged in sealed, moisture-controlled, light-resistant containers. Available in both R&D and bulk commercial quantities. Minimum order quantities (MOQ), lead times, and complete documentation including CoA and SDS are available to support clinical and commercial development.

Each batch is tested for identity, purity, appearance, residual solvents, heavy metals, and microbial content per USP standards. CarboMer ensures tight control of particle size and contaminant levels for safety and efficacy in both regulated pharmaceutical and personal care markets.

As with all CarboMer APIs and functional actives, Salicylic Acid USP is fully supported by technical formulation assistance, regulatory consulting, and lifecycle documentation to help partners advance safe, effective, and globally compliant topical therapies.
