Calcium Glycerophosphate BP
Abstract
Calcium glycerophosphate is a Calcium salt of glycerophosphoric acid that forms a white, fine, slightly hygroscopic powder. The commercial product is a mixture of calcium beta-, and D-, and L -alpha-glycerophosphate.
Use/Application
Calcium Glycerophosphate present in dental or oral hygiene products (toothpaste and mouthwash) due to its cariostatic effects. It is suggested that calcium glycerophosphate promotes plaque-pH buffering, elevation of plaque Calcium and phosphate levels and direct interaction with dental mineral. By FDA, calcium glycerophosphate is considered a generally recognized as safe (GRAS) food ingredient as a nutrient supplement (source of calcium or phosphorus), or in food products such as gelatins, puddings, and fillings. Other applications are in Animal Health, Cosmetics, Food & Beverage, and Sports Nutrition Vitamins & Minerals.
