What is of Sodium Monofluorophosphate?

Sodium Monofluorophosphate (Na₂PO₃F), often abbreviated as SMFP, is a white, odorless, water-soluble inorganic compound widely used as a fluoride source in oral care formulations. It plays a key role in strengthening tooth enamel and preventing cavities, making it a common ingredient in sodium monofluorophosphate toothpaste.

With CAS 10163-15-2, Sodium Monofluorophosphate (Na₂PO₃F) is known for its excellent stability and bioavailability of fluoride ions. Unlike some other fluoride compounds, it releases fluoride slowly, minimizing irritation while ensuring long-term protection.

If you are looking to buy sodium monofluorophosphate, we offer high-purity and cost-effective SMFP suitable for toothpaste, oral rinse, and other personal care formulations.

Sodium Monofluorophosphate Uses

Sodium monofluorophosphate uses span across oral care, pharmaceuticals, and specialty chemical applications:

Toothpaste Ingredient
The most common application is in sodium monofluorophosphate toothpaste formulations, typically containing sodium monofluorophosphate 0.76% as the active fluoride component. This concentration is equivalent to 1000 ppm fluoride, which is effective for cavity prevention.
Oral Care Products
Sodium monofluorophosphate in toothpaste works synergistically with calcium and phosphate ions to remineralize enamel and reduce demineralization. It provides a gentler fluoride delivery compared to sodium fluoride, ideal for sensitive users.
Pharmaceutical Additive
Used in dental care medications and fluoride supplements to promote enamel health and help restore minerals lost from teeth.
Industrial & Specialty Applications
Sodium fluorophosphate is also used in electroplating, cleaning formulations, and as a mild fluorinating agent in chemical synthesis.

Sodium Monofluorophosphate Benefits

Sodium monofluorophosphate benefits include:

Effective cavity protection by strengthening tooth enamel
Gentle fluoride release, minimizing irritation or over-fluoridation risk
Compatibility with calcium-based abrasives in toothpaste
Stability in formulations under various pH and temperature conditions
Scientifically proven performance for long-term dental health maintenance

Its superior safety profile makes SMFP one of the most trusted and widely used fluoride ingredients in toothpaste formulations worldwide.

Sodium Monofluorophosphate in Toothpaste

The use of sodium monofluorophosphate in toothpaste dates back decades as one of the first clinically approved fluoride compounds for dental care. In most commercial toothpastes, the concentration of sodium monofluorophosphate 0.76% provides about 1000 ppm of fluoride ions, the optimal level recommended for daily oral hygiene.

Compared with sodium fluoride, sodium monofluorophosphate na2po3f interacts gently with enamel and is less reactive toward calcium, allowing it to remain stable in formulations containing calcium carbonate abrasives.
