摘要： A process is described for stabilizing an aqueous preparation against microbial growth. Also described, is the aqueous preparation stabilized against microbial growth as well as the use of a source of at least one metal oxide and/or its hydrated form for reducing the amount of an antimicrobial agent against at least one strain of bacteria and/or at least one strain of yeast and/or at least one strain of mold in an aqueous preparation. The use of a composition including at least one antimicrobial agent and a source of at least one metal oxide and/or its hydrated form as an antimicrobial composition in an aqueous preparation, is also described. In addition, the use of magnesium oxide, magnesium hydroxide, calcium oxide, calcium hydroxide, half burnt dolomite, burnt dolomite, beryllium oxide, beryllium hydroxide, strontium oxide, strontium hydroxide, barium oxide, barium hydroxide, and mixtures thereof for increasing the pH of an aqueous preparation to a pH of above 8 and the use of an aqueous preparation stabilized against microbial growth in paper, plastics, polymer compositions, paint, coatings, concrete and/or agriculture applications are described.

摘要： A method of providing micronutrient delivery and/or plant protection is described, the method comprising administering a surface-reacted calcium carbonate as a metal cation releaser to deliver the micronutrient and/or provide plant protection. The surface-reacted calcium carbonate is obtained by a process comprising treating a calcium carbonate-comprising material with at least one H3O+ ion donor, carbon dioxide, and at least one water-soluble metal cation source in an aqueous medium to form an aqueous suspension of surface-reacted calcium carbonate.

摘要： 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.
