Sodium glycolate(CAS: 2836-32-0)

Sodium glycolate is the sodium salt of glycolic acid, with the chemical formula C2H4Na2O4. It appears as a white crystalline powder and is highly soluble in water. This compound is commonly used as a mild acid and serves as a precursor in various chemical syntheses. Its properties include hygroscopicity and reactivity with strong acids, making it a versatile material in industrial and research settings.

Sodium glycolate finds applications in pharmaceuticals as a buffering agent and preservative, in industrial processes as a chelating agent, and in the food industry as an acidulant or flavor enhancer. It is also used in research for analytical chemistry and as a reagent in organic synthesis. Its role in skincare products and as a precursor for glycolic acid derivatives further highlights its utility in multiple sectors.

Sodium glycolate is generally considered safe when handled properly, but it may cause skin or eye irritation in high concentrations. Safety standards recommend using appropriate protective equipment, such as gloves and goggles, and ensuring adequate ventilation. It is regulated by agencies like OSHA and EPA, and its safety in food and pharmaceutical applications is supported by compliance with established guidelines.

Sodium glycolate should be stored in a cool, dry place (below 25°C), away from moisture and direct light. Use airtight containers made of glass or high-density polyethylene (HDPE) to maintain stability. Keep it in a well-ventilated area and avoid contact with incompatible substances. Proper storage ensures its shelf life and prevents degradation or hazardous reactions.
