Abstract
The invention is a high humectant, low water, stannous fluoride containing toothpaste composition which maintains the stability and activity of the stannous fluoride over time, and methods for the preparation thereof. Stannous fluoride combined with from about 70 to about 92% humectant, and water present at less than 10% by weight, provides a stable toothpaste which avoids stannous fluoride degradation with time.
