Overview
Glycolic Acid Solution is a clear, colorless liquid derived from sugarcane or synthesized chemically. It belongs to the alpha-hydroxy acid (AHA) family and is renowned for its small molecular size, which allows deep skin penetration. This makes it highly effective in cosmetic and dermatological applications. In industrial settings, Glycolic Acid Solution is valued for its chelating and cleaning properties. It is biodegradable and less toxic compared to many other acids, making it an environmentally friendly choice for various applications.
Physical and Chemical Properties
Glycolic Acid Solution is characterized by its high solubility in water and organic solvents like alcohol and acetone. Its density varies with concentration, typically around 1.27 g/cm³ for a 70% solution. The pure compound has a melting point of 75-80°C but decomposes upon boiling at 100°C. The solution is acidic, with a pH ranging from 1.5 to 2.5 depending on concentration. It exhibits strong exfoliating properties due to its ability to break down intercellular bonds in the stratum corneum, making it a staple in skincare formulations.
Main Applications
In cosmetics, Glycolic Acid Solution is a key ingredient in anti-aging creams, peels, and moisturizers. Its exfoliating action promotes cell turnover, reducing wrinkles and improving skin texture. Dermatologists use it for treating acne, hyperpigmentation, and photoaging. Industrially, it serves as a cleaning agent for metal surfaces and equipment, particularly in the electronics and dairy industries. It is also used in leather tanning and textile processing due to its ability to soften and condition materials.
Safety and Storage
Glycolic Acid Solution is corrosive and can cause severe skin and eye irritation. Proper handling requires gloves, goggles, and protective clothing. In case of contact, rinse immediately with plenty of water and seek medical attention if necessary. Storage should be in a cool, dry place, away from direct sunlight and incompatible materials like strong oxidizers. Containers must be tightly sealed to prevent moisture absorption and degradation. Shelf life is typically 12-24 months when stored correctly.
B2B Procurement Guide
When procuring Glycolic Acid Solution, verify the concentration and purity levels, which should meet industry standards (e.g., 70% or 99% purity). Request certificates of analysis (CoA) and material safety data sheets (MSDS) from suppliers to ensure compliance with safety regulations. Bulk purchases often come with cost benefits, but ensure the supplier has reliable logistics for safe transport. Consider suppliers with ISO or GMP certifications for quality assurance. Price negotiations should factor in volume, concentration, and additional services like custom packaging.
