Sodium Nitrate

What is Sodium Nitrate?

Sodium nitrate is a simple inorganic compound, the sodium salt of nitric acid, appearing as colorless crystals or white powder. Synthetically produced or sourced from natural mineral deposits, it finds application in cosmetics mainly within oral care categories such as toothpastes and mouthwashes. There, it acts as an oral care agent, contributing to cleaning action, breath freshening, plaque management, and sensitivity support. Its soothing properties help ease sensations of discomfort in the mouth by promoting a calmer environment, potentially linked to its involvement in natural oral processes like nitrate conversion aiding antimicrobial balance. Buffering capabilities also help maintain product pH stability for effective performance without harshness.
