Abstract

A method for reducing the particle size of cellulose in water and/or an organic solvent (preferably water) comprising a) forming a slurry or paste of cellulose material in water, the cellulose material having a dry weight average particle size of 1 to 100 microns (preferably 1 to 20 microns); and b) reducing the average particle size of the cellulose material to 1 to 10 microns (preferably 1 to 3 microns), preferably by milling, to form a carrier ; an additive being optionally added to the water prior to addition of cellulose or to end of operations a) or b) above. The additive when added, is preferably an optical brightener. The method is useful in the field of paper coatings where it permits more efficient use of additives.
