- Keratolytic Action: Penetrates pores to dissolve excess sebum and dead skin cells, effectively unclogging pores and preventing comedones.
- Anti-inflammatory: Reduces redness, swelling, and irritation associated with acne and other skin conditions.
- Antibacterial: Exhibits mild antibacterial and antifungal properties, helping to control microbial growth on the skin.
- Cornific Agent: Promotes the shedding of the outer skin layer, making it essential for treating psoriasis, warts, calluses, and dandruff.
- Chemical Peel Agent: Used in controlled concentrations for professional skin peels to improve skin texture and tone.
- Cosmetics & Skincare: Acne cleansers, spot treatments, toners, serums, exfoliating peels, anti-dandruff shampoos, and wart removers.
- Medicals: Used in topical ointments, creams, plasters (e.g., corn plasters), and medicated powders.
- Food Preservation: Used as a preservative (E-number E914) in certain applications due to its antifungal properties.
- Industrial & Chemical Synthesis: Key intermediate in the production of aspirin (acetylsalicylic acid), dyes, fragrances, and other fine chemicals.
- Agriculture: Utilized in some plant hormone formulations.
We employ a state-of-the-art Kolbe-Schmitt synthesis process, ensuring optimal purity and batch-to-batch consistency:
- Phenolation: Sodium phenoxide is reacted with carbon dioxide under controlled temperature and pressure.
- Carboxylation: Formation of the sodium salt of salicylic acid.
- Acidification: The sodium salt is treated with a strong mineral acid (e.g., sulfuric acid) to precipitate crude Salicylic Acid.
- Purification: Multiple stages of recrystallization and washing are performed to achieve medical-grade purity (>99.5%).
- Drying & Milling: The purified crystals are dried under vacuum and milled to specified particle sizes.
- Quality Control: Every batch undergoes rigorous HPLC, GC, and spectroscopic analysis to confirm identity, potency, and absence of impurities.
- High Purity Guaranteed: We supply 99.5%+ pure Salicylic Acid compliant with USP, BP, EP, and FCC standards.
- Global Supply Chain: Reliable logistics ensuring on-time delivery to customers worldwide.
- Technical Expertise: Over [X] years of experience in fine chemical manufacturing with dedicated R&D and application support.
- Customization: Available in various mesh sizes (powder/granular) and tailored packaging (from 1kg to 25kg drums).
- Certifications: Our facility is ISO 9001, ISO 14001, and cGMP certified, guaranteeing quality and safety.
- Competitive Pricing: Direct manufacturer pricing without intermediaries, offering excellent value.
A: For over-the-counter (OTC) leave-on products, concentrations typically range from 0.5% to 2%. For rinse-off products like cleansers, it can be higher. Professional peels may use up to 30%. Always formulate within safe and regulatory limits for your target market.
A: Yes. Our product meets stringent pharmacopeial monographs (USP/BP/EP) and is manufactured in a cGMP-compliant facility, making it ideal for API use in topical medicals.
A: Store in a tightly closed container in a cool, dry, well-ventilated area away from heat, moisture, and incompatible materials like strong oxidizers and bases.
A: Our standard MOQ is 25kg, but we offer flexibility for sample orders and new partnerships. Please contact our sales team for specific inquiries.
A: Absolutely. A comprehensive TDS and a batch-specific CoA are provided with every shipment to ensure full transparency and quality assurance.
