    摘要： The present invention relates to the use of a surface-reacted calcium carbonate as an anti-blocking agent in polymer(s) containing compositions, wherein the surface-reacted calcium carbonate is a reaction product of natural ground or precipitated calcium carbonate with carbon dioxide and one or more H3O+ ion donors in an aqueous medium, wherein the carbon dioxide is formed in situ by the H3O+ ion donors treatment and/or is supplied from an external source, an anti-blocking agent comprising surface-reacted calcium carbonate or a combination of surface reacted calcium carbonate and mineral material, a method for controlling the blocking of polymer(s) containing compositions, a polymer(s) containing composition comprising surface reacted calcium carbonate or a combination of surface reacted calcium carbonate and mineral material, a coating composition comprising such polymer(s) containing composition, as well as a substrate coated with such coating composition.

    摘要： The present invention relates to the use of zinc treated precipitated calcium carbonate (PCC), which is obtained by slaking calcium oxide with water to obtain a calcium hydroxide slurry, carbonating the calcium hydroxide slurry, and adding a Zn2+ ion provider before and/or during the carbonation, in hygienic products, to the hygienic products comprising said zinc treated precipitated calcium carbonate as well as to a process for the preparation of such hygienic products.
