Attorney, Agent or Firm: Connolly and Hutz
A toothpaste composition contains an alkali metal aluminum silicate zeolite as the polishing agent base. The composition is non-corrosive to aluminum containers, polishes well without excessive abrasion and is compatible with dental fluorine compounds. A particularly suitable polishing agent is Zeolite A having the empirical formula Na.sub.12 (AlO.sub.2).sub.12.(SiO.sub.2).sub.12.27H.sub.2 O. |

Description:
The present invention relates to a tooth paste which has no corrosive effect against bare (unlacquered) aluminum surfaces and which contains synthetic zeolite of the alkali aluminum silicate type as the sole and preponderant polishing agent.
In a tooth paste, the polishing agent quantitatively is the most important constituent aside from water and the moistureholding agents.
The best known polishing agents used in tooth pastes are calcium carbonate, the various calcium phosphates, such as dicalcium orthophosphate and calcium pyrophosphate in particular, insoluble alkali metaphosphate, precipitated silicon dioxide gel, either in the form of a hydrogel or of the dried xerogel.
These cleaning substances as well as aluminum hydroxide, having come into use because of their refractive indices make them useful particularly in the preparation of transparent and translucent tooth pastes.
The further numerous substances proposed as polishing agents in tooth pastes essentially have not achieved practical importance but rather represent merely "paper prior art
