Abstract
The present invention relates to a dentifrice composition comprising: a) a polyphosphate salt in particulate form, the polyphosphate salt comprising a polyphosphate anion comprising at least 10 phosphate units; and b) an orally acceptable carrier; characterised in that the polyphosphate salt has a particle size distribution wherein less than 10% by volume of the salt has a particle size of greater than 160 μm and less than 20% by volume of the salt has a particle size of less than 20 μm. The dentifrice composition has good stability and acceptable mouth feel. The invention further relates to orally acceptable polyphosphate salts for use in such compositions.
Claims11
A dentifrice composition comprising:
- a) a water soluble polyphosphate salt in particulate form, the polyphosphate salt comprising a polyphosphate anion comprising at least about 10 phosphate units;
- b) an orally acceptable carrier;
- wherein the polyphosphate salt has a particle size distribution wherein less than about 10% by volume of the salt has a particle size of greater than about 160 μm and less than about 20% by volume of the salt has a particle size of less than about 5 μm.
An orally acceptable, water soluble polyphosphate salt in particulate form, the polyphosphate salt comprising a polyphosphate anion comprising at least about 10 phosphate units and having a particle size distribution wherein less than about 10% by volume of the salt has a particle size of greater than about 160 μm and less than about 20% by volume of the salt has a particle size of less than about 5 μm.
