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.

Dentifrice composition

A plastic container is filled with an antiseptic toothpaste composition comprising an aluminum oxide compound such as aluminum oxide trihydrate as a main abrasive and a polyhydric alcohol such as propylene glycol, sorbitol, etc. in an amount of 5 to 100 moles in fluoride-free systems or 4.0 to 100 moles in fluoride-containing systems per liter of water in the toothpaste composition.

Toothpaste composition and plastic containers containing the same

A dentifrice composition is disclosed which comprises 100-100,000 units per gram of the composition of dextranase and 20-90% by weight of the composition of an aluminum oxide compound having the formula:

A plastics container having oxygen permeability of 3 cc/m.sup.2.day.atm or more is filled with an antiseptic toothpaste composition comprising an aluminum oxide compound such as aluminum oxide trihydrate as a main abrasive and a polyhydric alcohol such as propylene glycol, sorbitol, etc. in an amount of 5 to 100 moles in fluoride-free systems or 4.0 to 100 moles in fluoride-containing systems per liter of water in the toothpaste composition.

Toothpaste composition

A stable dextranase-containing oral composition having a good feeling upon use is disclosed which comprises a dextranase enzyme produced by the genus Chaetomium, one of fungi, and a stabilizing amount of an admixture comprising water-soluble salts of alkyl sulfates having 10, 12, 14, and 16 carbon atoms in the alkyl chain in the following proportion:
