Products Description
Our 99% cosmetic‑grade Glycolic Acid Powder (INCI: Glycolic Acid, CAS 79‑14‑1) represents the smallest‑molecule alpha‑hydroxy acid available for cosmetic manufacturing. As a high‑purity crystalline AHA active, it weakens intercellular adhesion between corneocytes to boost natural desquamation, supporting smoother skin texture and fading uneven skin tone. Thanks to its ultra‑low molecular weight, this powder dissolves fully in water and ethanol, enabling easy integration into water‑based cosmetic systems.
When incorporated into finished formulations, glycolic acid helps to speed up stratum corneum turnover, reduce dullness, and stimulate dermal fibroblast activity for enhanced extracellular matrix production. This sealed‑stable crystalline powder is strictly refined for cosmetic usage with tight heavy‑metal and organic‑impurity control. Beyond acting as a chemical exfoliant, it also works as a skin conditioner and mild pH adjuster within cosmetic formulas. Please note that final product irritation risk heavily depends on working concentration and finished‑product pH value. Industrial‑grade glycolic acid with relaxed impurity thresholds is not interchangeable with this cosmetic‑grade material for skincare production.

Frequently Asked Questions
Q1: What key differences separate cosmetic‑grade glycolic acid powder from industrial‑grade glycolic acid?
A: Cosmetic‑grade implements strict limits for heavy‑metal traces and organic impurities for safe skin contact. Industrial‑grade targets descaling and metal‑treatment scenarios only and must never be used for skincare manufacturing.
Q2: What shelf‑life can I expect for 99% glycolic acid powder and how should I store inventory?
A: Sealed original packaging retains 2‑year shelf‑life. Store in cool dry ventilated warehouse areas. Keep away from temperatures exceeding 45℃, direct sunlight exposure and strong alkaline substances.
Q3: What addition percentage should I adopt when developing leave‑on skincare formulas?
A: For daily leave‑on cosmetic goods, 2‑10% loading is recommended. Always adjust finished‑product pH ≥3.5 to reduce skin‑irritation possibility.
Q4: Is glycolic acid powder compatible with vitamin‑C raw materials in one‑pot mixing?
A: Direct high‑concentration mixing with L‑VC is not advised. Severe pH shift may trigger ingredient degradation; formulators are suggested to test stability under your exact formula conditions.
Q5: Can you supply free samples for lab testing before formal bulk purchase?
A: Yes, sample service is available. Reach out to our sales team to apply for testing samples; sample freight cost may apply according to destination country.
Q6: What safety hazards do I need to observe during powder handling in my workshop?
A: Glycolic acid powder is corrosive. Wear protective goggles, chemical‑resistant gloves and protective clothing. In case of skin or eye contact, flush abundantly with clean water and seek medical help if irritation persists.
Q7: Which shipping transport option fits my order weight?
A: Orders under 100 kg: DHL/FedEx door‑to‑door express; 100‑1000 kg: Air freight airport‑to‑airport; above 300 kg: Ocean sea freight service. Customs clearance assistance is offered.
Q8: What certificates and test reports can you provide for each shipment batch?
A: Each shipment comes with COA (Certificate of Analysis), MSDS safety datasheet, heavy‑metal test report and cosmetic‑grade safety inspection report.
