Abstract

A dentrifice powder, which when dissolved in water yields hydrogen peroxide, consists of a mixture of an alkali metal perborate and mono-calcium or mono-magnesium phosphate. The perborate is preferably sodium perborate and may be wholly or partially dehydrated. The acid phosphate is stated to neutralize the caustic soda formed. The Specification as open to inspection under Sect. 91 refers also to the use, in place of the mono - calcium phosphate, of acid salts in general, and particularly of other mono-basic salts of poly-basic acids, sodium mono-phosphate and calcium bi-phosphate being given as examples. This subject - matter does not appear in the Specification as accepted.ALSO:A dentifrice powder consists of alkali metal perborate and monocalcium or monomagnesium phosphate, and may contain also common salt, saccharine, oil of peppermint, and polishing agents such as calcium or magnesium carbonates or phosphates, silica or aluminium hydrate. The perborate is preferably sodium perborate and may be wholly or partially dehydrated. When the mixture is added to water the perborate decomposes yielding hydrogen peroxide and caustic soda which is immediately neutralized by the acid salt with the formation of colloidal or amorphous precipitates adapted to serve as cleaning or polishing agents. The Specification as open to inspection under Sect. 91 refers also to the use, in place of monocalcium phosphate, of acid salts in general, and particularly of other mono-basic salts of poly-basic acids, "sodium monophosphate" and "calcium biphosphate" being given as examples. This subject-matter does not appear in the Specification as accepted.
