About
A well-tolerated magnesium/glycerophosphate salt used in toothpaste for remineralisation support.
Magnesium glycerophosphate (CAS 927-20-8) is a pharmaceutical-grade salt of magnesium and glycerophosphate used both as an oral supplement and as a dentifrice ingredient. In oral care it supplies magnesium and phosphate for enamel remineralisation and acts as a mild buffer. It has a pharmaceutical safety dossier (listed in various pharmacopoeias) and excellent biocompatibility. No known cosmetic-relevant toxicity; GHS-free of hazard pictograms. EU CosIng accepts it without restriction.
