  • 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.

  • Patent number: 4357313
    Abstract: A toothpaste of improved rheological properties wherein drying and plug formation is reduced or prevented. The toothpaste contains a vehicle in which there is present about 45-85% by weight of liquid phase containing up to about 35% by weight of sorbitol and at least about 25% by weight of water and a solid phase including about 0.5-10% by weight of gelling agent. Drying and plug formation is reduced by including in the liquid phase about 5-20% by weight of polyethylene glycol having an average molecular weight between about 900 and 1600.

  • Patent number: 4307076
    Abstract: A toothpaste composition comprising a vehicle containing about 45-80% by weight of liquid phase, comprising up to about 35% by weight of the toothpaste of sorbitol and at least about 25% by weight of the toothpaste of water and a solid phase including about 3-10% by weight of the toothpaste of gelling agent comprising at least about 3% by weight of the toothpaste of polyvinyl pyrrolidone as an agent to reduce drying and tube plugging.
