Abstract: Dentifrices, including toothpaste creams and gels, and mouthwashes, are provided including aminoalkyl silicones. In the mouth, the aminoalkyl silicones form a lasting hydrophobic film on the teeth for prevention of cavities and stain. Antimicrobial compounds such as chlorhexidine may be included.

Abstract: Disclosed is a packaged effervescible composition which generates fresh effervescence at the time of use. The composition comprises a first liquid component including hydrogen peroxide as a functional ingredient and a second liquid component including sodium bicarbonate as a functional ingredient. The package comprises a container for the components and a closure system comprising an inclined crown portion, at least two pouring spouts extending upwardly from the upper surface of the crown and a cover for securement to the crown portion, the cover being provided with depending plugs to close the closure. Preferably each pouring spout is provided with a vent opening which allows smaller through openings in the spouts. The through openings can thus be positioned closer together on the crown. This gives the advantage that the package can be used dispensing liquids into a small container such as a mouthwash cup with controlled pouring.

Abstract: An oral composition is provided that includes a peroxygen compound such as hydrogen peroxide, a fluoride-containing anticaries agent and a tin compound, especially stannous chloride. The tin compound stabilizes the peroxygen compound against decomposition that ordinarily would be induced by the presence of fluoride.

Abstract: An oral composition is provided having exceptional anti-plaque action, the composition comprising a bicarbonate salt, a copper compound and a complexing agent to stabilize the copper.

Abstract: The invention provides a process for microbiologically stabilizing a premix phase intended to receive bicarbonate in the manufacture of toothpaste. The process includes blending together in the premix phase a polyol, a thickening agent, a copper compound and water. The premix phase is maintained at a temperature no higher than 110.degree. F. for a time sufficient to destroy bacteria. Thereafter the bicarbonate is incorporated into the premix phase without cool-down of the premix phase. There is also disclosed an oral composition that includes a combination of humectant, thickening agent, copper, bicarbonate and water.
