Oral Polyphosphate Compositions

摘要

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 mum and less than 20% by volume of the salt has a particle size of less than 20 mum. The dentifrice composition has good stability and acceptable mouth feel. The invention further relates to orally acceptable polyphosphate salts for use in such compositions.
