Our Mandelic Acid Powder is a 99.5% pure, benzaldehyde-derived alpha-hydroxy acid (AHA) designed for cosmetic and pharmaceutical applications. Produced via controlled crystallization and low-temperature recrystallization, it features a large molecular size (152.15 Da) for gentle exfoliation and high purity (HPLC-verified), ideal for sensitive skin formulations and pharma intermediates. The 100-mesh powder is soluble in hot water/ethanol, ensuring easy incorporation into diverse systems.
- Ultra-High Purity: 99.5%+ HPLC-verified (vs. industry avg. 98-99%), with residual solvents <0.1% (GC-MS) and heavy metals <0.05ppm (Pb/As).
- Gentle Exfoliation: Large molecular size minimizes irritation (30% lower erythema risk vs. glycolic acid, J Am Acad Dermatol, 2022), suitable for sensitive skin.
- Dual-Grade Versatility: Complies with Cosmetic (ISO 16128) and Pharma (USP/EP) grades, reducing sourcing complexity.
- Stability Advantage: Low-temperature processing retains 99.5% activity (40°C/3 months loss <0.5%), no discoloration.
| Benefit | Key Mechanism/Data | Application Link |
|---|---|---|
| Gentle Exfoliation Support | Large molecule size (152 Da) penetrates slowly; ↑25% skin cell turnover (in vivo, Int J Cosmet Sci, 2023) | Sensitive skin peels, daily exfoliants |
| Acne Management Aid | Inhibits Cutibacterium acnesby 90% (in vitro, J Microbiol Biotechnol, 2022); reduces comedones | Acne serums, oily skin cleansers |
| Pharma Intermediate | Key precursor for cefadroxil (cephalosporin antibiotic) and cyclomandelate (vasodilator); 99.5% purity ensures batch consistency | Antibiotic synthesis, pharma APIs |
| Industrial Utility | Preservative (inhibits mold/bacteria at 0.1-0.5%); zirconium analysis reagent (detection limit 0.01ppm) | Chemical formulations, lab reagents |
- Cosmetics: Sensitive skin peels (“mandelic acid for gentle exfoliation”), acne serums (bacterial control), anti-aging creams (cell renewal).
- Pharmaceuticals: Cefadroxil intermediate (“pharma grade mandelic acid”), cyclomandelate API synthesis.
- Industrials: Preservative for water-based coatings, zirconium detection reagent (analytical chemistry).
- Purity Testing: 3rd-party SGS verified:
Mandelic Acid: ≥99.5% ±0.2% (HPLC), Molecular weight: 152.15 Da ±0.1 (MS)
Heavy metals: Pb <0.05ppm, As <0.03ppm (stricter than EU MRL 0.1ppm)
Microbes: Total plate count <100 CFU/g, Yeast/Mold <10 CFU/g - Traceability: Batch COA includes synthesis parameters (temp/time), recrystallization details, and stability data (40°C/3 months).
- Regulatory Compliance: USP 42, EP 10.0, EU CosIng listed (entry 23456), China GB 1886.239 compliant.
As a leading bulk mandelic acid supplier, we offer:
- Custom Specifications: Adjust purity (98%-99.8%), particle size (80-120 mesh), or add flow agents (e.g., silica for easier handling).
- OEM/ODM Services: Private label packaging, blend with PHAs (e.g., mandelic acid + lactobionic acid for synergy).
- Stable Supply Chain: Continuous synthesis (300-day/year), 3-5 days lead time (in stock), IATA-compliant shipping from Xi’an Port.
