Abstract
A two component efficacious dentifrice composition, having a first alkali metal bicarbonate containing dentifrice component and a second acid-containing dentifrice component; the first and second components being separated prior to use; wherein, the pH of the two components when combined upon application to the teeth is between about 6.0 and about 7.1; whereby, the dentifrice provides enhanced removal of plaque growth and a tingly mouth feel.
Claims12
A two component dentifrice composition comprising a first dentifrice component containing alkali metal bicarbonate in a vehicle with a humectant content of from about 10 to about 30% and a water content of about 40 to about 55% and a second dentifrice component containing acid in a vehicle with a humectant content of from about 10 to about 30% and a water content of about 40 to about 55%;
- the first and second dentifrice components being separated in separate compartments of a two component dentifrice dispensing means prior to use;
- wherein, the pH of the two dentifrice components when combined upon dispensing and application to the teeth is between about 6.0 and about 7.1;
- whereby, the dentifrice provides enhanced removal of plaque growth and a tingly mouth feel.
A method for enhancing the removal of plaque growth and providing a novel tingling mouth feel which comprises preparing a two component dentifrice;
- the first dentifrice component containing an alkali metal bicarbonate in a vehicle with a humectant content of from about 10 to about 30% and a water content of about 40 to about 55%, the second dentifrice component containing an acid in a vehicle with a humectant content of from about 10 to about 30.degree. and a water content of about 40 about 55% maintaining the first and second dentifrice components separate from each other in respective compartments of a two component dentifrice dispensing means until dispensed for application to teeth;
- whereupon the pH of the two dentifrice components when combined to form the dentifrice composition and applied to the teeth will be between about 6.0 and 7.1.
