摘要：
The present invention relates to a method for the control of odour by contacting surface-reacted calcium carbonate with odourants, wherein the surface-reacted calcium carbonate is a reaction product of natural ground or precipitated calcium carbonate with carbon dioxide and one or more acids, wherein the carbon dioxide is formed in situ by the acid treatment and/or is supplied from an external source, to the use of the surface-reacted calcium carbonate for the control of odour, as well as to products for the control of odour containing surface reacted calcium carbonate.
