Calcium Sodium Phosphosilicate
What is Calcium Sodium Phosphosilicate?
Calcium sodium phosphosilicate is a laboratory-synthesized bioactive glass composed primarily of silica, sodium oxide, calcium oxide, and phosphorus pentoxide. It appears as fine, white particles designed for incorporation into toothpaste and mouthwashes. In these formulations, it interacts with saliva's aqueous environment, partially dissolving to release calcium, phosphate, sodium, and silicate ions. This ionic exchange promotes the formation of a protective hydroxycarbonate apatite layer similar to natural tooth enamel on exposed dentin surfaces and around teeth. Primarily functioning in oral care categories, it enhances product performance for cleaning and hygiene maintenance without abrasiveness typical of some agents.
