Abstract:
A two phase remineralising composition comprising:a) as a first component an aqueous calcium phase comprising a water-soluble calcium salt providing from 0.05 to 10%, by weight of the calcium phase, of calcium ions, andb) as a second component an aqueous phosphate phase comprising a stabilising amount of a polyphosphate salt and a water-soluble phosphate salt providing from 0.05 to 10%, by weight of the phosphate phase, of phosphate ions; the two phases being kept separate until use, whereupon on mixing they provide a single phase having a pH from 2.0 to 5.0 and a molar ratio of calcium ions to phosphate ions of from 0.5:1 to 5:1 capable of remineralising teeth.
