Abstract: The present invention relates to the use of a loaded particulate carrier comprising surface-reacted calcium carbonate loaded with an active ingredient, characterized in that the loaded particulate carrier is used for preparing an aqueous system comprising said active ingredient in dissolved form, wherein the mass concentration of dissolved active ingredient in said aqueous system corresponds to a supersaturated state. The surface-reacted calcium carbonate is a reaction product of calcium carbonate treated with CO2 and one or more H3O+ ion donors, wherein the CO2 is formed in situ by the H3O+ ion donors treatment and/or is supplied from an external source.

Abstract: The present invention relates to a process for the preparation of a surface-reacted precipitated calcium carbonate (PCC) pigment having an insoluble, at least partially crystalline calcium salt on its surface. In the process of the present invention, a PCC containing pigment is contacted with H3O+ ions and a solubilized anion in an aqueous medium in the presence of excess solubilized calcium ions to form the surface-reacted PCC having an insoluble, at least partially crystalline calcium salt of the anion formed on its surface.
