Abstract:
The present invention relates to surface-reacted calcium carbonate, wherein the surface-reacted calcium carbonate is a reaction product of natural or synthetic calcium carbonate with carbon dioxide and at least one acid. Said calcium carbonate and oral compositions containing the same can be used in remineralisation and/or whitening of teeth.

Claim (Index 14):
The oral care composition of  claim 1 , wherein the surface-reacted calcium carbonate is obtained by a process comprising the steps of:\n a) providing an aqueous suspension of natural or synthetic calcium carbonate, wherein the aqueous suspension has a solids content in the range of 5 to 25 wt.-%, based on the weight of the aqueous suspension, and the amount of natural or synthetic calcium carbonate having a weight based particle size of less than 1 \u03bcm is at least 80 wt.-%, based on the total amount of natural or synthetic calcium carbonate, and b) adding at least one H 3 O + -ion donor to the suspension of step a), and c) treating the suspension of step a) with carbon dioxide before, during or after step b), wherein the carbon dioxide is formed in-situ by the H 3 O + -ion donor treatment and/or is supplied from an external source.
