Sodium Monofluorophosphate

What is Sodium Monofluorophosphate?

Sodium monofluorophosphate is an inorganic compound, specifically the sodium salt of monofluorophosphoric acid, commonly incorporated into oral care formulations such as toothpastes and mouthwashes. It serves as a controlled source of fluoride ions, which are released gradually through enzymatic hydrolysis in the mouth. This mechanism allows fluoride to interact with tooth enamel, supporting remineralization processes and inhibiting the activity of enzymes involved in demineralization. Primarily categorized under oral hygiene actives, it functions by integrating into the hydroxyapatite structure of teeth, forming a more acid-resistant fluorapatite layer. Its inclusion in cosmetic oral products enhances their performance in maintaining dental health without altering product texture or flavor significantly. Regulatory bodies recognize its role in dentifrice compositions at established levels.
