- Stability: Stable at room temperature but may polymerize under high temperatures or prolonged storage.
- Functionality: Exhibits excellent chelating, exfoliating, and moisturizing properties.
Applications
As a versatile organic acid, glycolic acid is widely used in:
Cosmetics & Personal Care：Key ingredient in chemical peels, anti-aging creams, and acne treatments due to its exfoliating and skin-renewal effects.
Industrial Cleaning：Effective in metal descaling, textile processing, and cleaning agents for its ability to dissolve rust and mineral deposits.
Biodegradable Polymers：Monomer for polyglycolic acid (PGA), a biodegradable plastic used in medical sutures and packaging.
Pharmaceuticals：Intermediate in drug synthesis (e.g., antibiotics, dermatological preparations).
Electroplating：Used in electroplating baths to improve surface finish.
Packaging & Storage
- Packaging: 250kg or 1250kg/drum (aqueous solution)
- Storage: Store in a cool, dry place (<25°C) away from sunlight.
