  • Hazed toothpaste
    Patent number: 4425324
    Abstract: A hazed toothpaste which can effect dental remineralization and reduce caries formation. The toothpaste contains a binary fluorine-providing system which provides about 750-1225 ppm fluoride from sodium monofluorophosphate and about 50-1000 ppm fluorine from sodium fluoride and a synthetic precipitated siliceous polishing agent. The toothpaste is stabilized against gassing in an unlined aluminium tube by the presence of a dicalcium phosphate which exerts a hazing effect on the toothpaste. Dicalcium phosphate also reduces color fading when a water-soluble dye is present. Additional haze to permit opacification of the toothpaste may be introduced by the presence of an opacifying agent, such as titanium dioxide.
