Sodium Glycerophosphate
What is Sodium Glycerophosphate?
Sodium glycerophosphate is the sodium salt of glycerophosphoric acid, a molecule formed by esterifying glycerol with phosphoric acid, resulting in a water-soluble white powder. Synthetically produced for stability, it belongs to the phosphate ester family. Primarily used in oral care cosmetics such as toothpastes and mouthwashes, it functions as a buffering agent to help maintain optimal pH levels in formulations, preventing drastic shifts that could affect product efficacy. As a humectant, it aids moisture retention, keeping products from drying out. In oral hygiene products, it supports cleaning and freshening actions while contributing to antiplaque performance by influencing bacterial environments and limiting biofilm formation on teeth. Its mild nature makes it suitable for daily-use formulas, enhancing overall product stability without harsh effects.
