    Abstract: A process is described for the surface-treatment of a surface-reacted calcium carbonate. Also described, is a surface-treated surface-reacted calcium carbonate obtainable by the process, as well a composition including the surface-treated surface-reacted calcium carbonate . Methods of using at least one surface-reacted calcium carbonate for immobilizing at least one water soluble metal salt, water soluble metal hydroxide, water soluble metal oxide or mixtures thereof on the surface of the at least one surface-reacted calcium carbonate are also described. In addition, methods of using a surface-treated surface-reacted calcium carbonate as a preservative, for the control of odor and/or for enhancing and/or mediating antimicrobial activity of a substrate and an article including the surface-treated surface-reacted calcium carbonate are described.
