Abstract
Abstract A dentifrice composition having an excellent storage-stability which comprises a zirconium-bonded synthetic amorphous silicate (zirconosilicate) with a zirconium content of 0.1 to 10% by weight as ZrO 2 based on SiO 2 and a dentifrice vehicle containing water, humectant and flavor, and by adjusting the refractive index of the vehicle substantially identical with that of the silicate, the dentifrice composition can be made transparent.
