DENTIFRICE Emil Klarmann, Bloomfield, and Louis w. Gates,
Verona, N. 1., assignors to Lehn & Fink Products Corporation, Bloomfield, N. J., a corporation of Delaware No Drawing. Application January 10, 1936, I
Serial No. 58,536
5 Claims.
The present invention relates to dentifrices and more particularly to dentifrices containing a novel ingredient having a high polishing and cleansing effect and without deleterious abrasive or scratch- 5 ing action on the tooth surfaces.
We have found that the relatively water-insolreduced to a fine particle form as for example the precipitated hydrated tri-magnesium phosphates such as magnesium orthophosphate tetrahydrate Mg3(PO4)2.4H2O, the magnesium orthophosphate pentahydrate Mg3(POi)2.5I-IzO, and magnesium 25 orthophosphate octahydrate Mga(PO4) 2.81120. While the hydrated tri-magnesium phosphates are-preferred, our invention is not to be construed as limited thereto as other water-insoluble hydrated, non-acid magnesium phosphates may 30 be employed as, for example, the hexahydrated magnesium-ammonium. phosphate The compounds embodying our invention, when 35 used as dentifrices per se-or in combination with other normal constituents in paste or powder form, are capable of removing the objectionable deposits from and polish the teeth without abrading or scratching the surfaces thereof; and re- 40 store and maintain the natural lustreof the teeth. The dentifrice embodying our invention has no deleterious effect on the enamel or cementum of the teeth. These compounds are sub- 5 stantially colorless and tasteless and as stated above are employed in a fine particle form so that all possibility of scratching or abrading the enamel or cementum of the teeth is eliminated. The following example is illustrative of a typical 50 tooth paste formula containing an insoluble hydrated magnesium phosphate as the polishing ingredient:
\ Per cent ME3(PO4)2.4H2O 25 Soap (anhydrous) 2 Magnesium hydroxide 4 Sugar 13 Glycerine 25 Flavor 1 v Water 30 The following example is illustrative of a typicaltooth powder formula:
Per cent Mgs(PO4)2.8H2O 82 Soap (anhydrous) l4 Magnesium hydrate 1 Flavor 3 It is, of course, to be understood that our invention is not limited to the above compositions as the insoluble hydrated magnesium compound may be used as a dentifrice per se or combined in any desired proportions with other desirable dentifrice ingredients, such as massingagentsf diluents, flavoring agents, detergents, emollients and the like.
We claim:
1. A dentifrice containing a substantially water-insoluble hydrated tri-magnesium phosphate in finely divided form so as to act as a polishing and cleansing agent.
2. A substantially non-abrasive dentifrice containing tri-magnesium orthophosphate tetrahydrate in fine particle form.
3. A. substantially non-abrasive dentifrice containing tri-magnesium orthophosphate octahy- I drate in fine particle form.
4; A substantially non-abrasive dentifrice containing hexahydrated magnesium ammonium phosphate in fine particle form.
5. A substantially non-abrasive dentifrice composition containing a substantially waterinsoluble hydrated phosphate selected from the class consisting of substantially water-insoluble hydrated tri-magnesium phosphates and hexahydrated magnesium ammonium phosphate in finely divided form so as to act as a polishing and cleansing agent.
