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.
