Abstract
Abstract Stable aqueous peroxide dentifrice gel compositions which are stable against both viscosity and peroxide loss and which contain up to 15% by weight of aqueous peroxide, and from about 35% to about 95% by weight of a polyol or a mixture of polyols, from out 0.75% to about 5.0% by weight of a gelling agent and from about 0.05% to about 1.0% by weight of stabilizers are disclosed.
