Sodium Glycolate
What is Sodium Glycolate?
Sodium glycolate is the sodium salt of glycolic acid, a naturally derived alpha-hydroxy acid from sources like sugarcane or produced synthetically. Chemically, it is sodium 2-hydroxyacetate, a water-soluble compound that dissociates in solution. In cosmetics, it belongs to the category of pH adjusters and buffering agents, commonly found in cleansers, toners, and exfoliating products. Its primary function is to maintain a stable pH level, preventing fluctuations that could destabilize active ingredients or alter product efficacy. By neutralizing excess acidity, it supports the overall integrity of formulations, particularly those with alpha-hydroxy acids, allowing for consistent performance and skin compatibility during application.
