摘要:
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.sub.2 based on SiO.sub.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.
摘要:
Transparent and translucent dentifrice compositions improved in cleaning ability, stain removing ability and feeling are disclosed which comprise a mixture of an amorphous silica and an amorphous silicate containing at least 70% by weight of SiO.sub.2 which is partially inter-bonded with 1-10% by weight of an oxide of a metal selected from the group consisting of aluminum, magnesium and calcium and a transparent vehicle having substantially the same refractive index as that of the silica, the ratio of the silica to the silicate being in the range of 4:6 to 6:4 on a weight basis, the content of said mixture being in the range of 1 to 25% by weight of the composition, and the pH of the composition being in the range of 4.5 to 10.
