摘要： The present invention refers to Pickering emulsion comprising (i) water; (ii) 10 to 50 wt.-% oil, based on the total weight of the Pickering emulsion and (iii) 1 to 10 wt.-% of Pickering pigments, based on the total weight of the Pickering emulsion, wherein the Pickering pigments are calcium carbonate particles selected from surface-reacted calcium carbonate (SRCC) or mixtures of ground calcium carbonate (GCC) and surface-reacted calcium carbonate (SRCC) and wherein the calcium carbonate particles have a volume median particle size d50 value from 0.2 µm to 10 µm. Furthermore, the present invention refers to a composition comprising said Pickering emulsions and a method of preparing such Pickering emulsions. The present invention also refers to the use of calcium carbonate particles as Pickering pigments for stabilizing Pickering emulsions comprising water and 10 to 50 wt.-% oil, based on the total weight of the Pickering emulsion, wherein the calcium carbonate particles are selected from surface-reacted calcium carbonate (SRCC) or mixtures of ground calcium carbonate (GCC) and surface-reacted calcium carbonate (SRCC) and have a volume median particle size d50 value from 0.2 µm to 10 µm.
