Abstract: A substrate having about 0.5 wt % to about 25 wt % gum incorporated upon it is provided that provides the benefit of delayed viscosity when incorporated into a person care composition such as a toothpaste. Also disclosed is a method for forming gum incorporated onto or into a substrate comprising the steps of: providing a substrate; introducing a liquefied solution of gum to the substrate; and optionally drying the gum-treated substrate to form a dried gum-treated substrate. The invention further includes a dentifrice comprising a gum-treated substrate, and one or more ingredients selected from the group consisting of humectants, abrasives, thickening agents, binders, stabilizing agents, antibacterial agents, fluorides, sweeteners, and surfactants.
