Oral care compositions comprising tin ions

Abstract

An oral care composition with tin, polyol with five or more carbon atoms, water, and a pH of greater than 7. An oral care composition with a tin ion source, a fluoride ion source, a polyol with five or more carbon atoms, water, and a pH of greater than 7. Oral care compositions with a high tin ion availability.

Description

technical field [0001] The present invention relates to compositions comprising tin and a polyol at a pH greater than 7. The present invention also relates to compositions comprising stannous fluoride and a polyol having five or more carbons at a pH of from about 7.5 to about 10. The present invention also relates to compositions comprising tin, polyols and polyphosphates at a pH greater than 7. The present invention also relates to compositions comprising stannous fluoride or stannous chloride in combination with a polyol having five or more carbons and a polyphosphate at a pH of from about 7.5 to about 10. Background technique [0002] A source of tin ions, such as stannous fluoride, is added to dentifrice compositions to deliver antimicrobial and antiallergic benefits. However, sources of tin ions can be difficult to incorporate into dentifrice compositions due to (i) reactivity between tin ions and other dentifrice components such as silica and (ii) formation of insolu...

AI Technical Summary

Problems solved by technology

However, polyols can be expensive relative to other carrier materials in water-based dentifrice compositions

Therefore, there is a need for stable water-based dentifrice compositions that do not require chelating agents that may be detrimental to the availability of tin ions in the dentifrice composition
