Granules of textile processing agents for use in organic solvent liquors

Claim 1

Non-dusty, free-flowing granules of optical brightener for solvent application, said granules containing an optical brightener, alone or together with a dispersing agent or auxiliary, dissolved in a melt of an organic carrier which is solid at room temperature, soluble in halogenated hydrocarbon and immiscible in water, selected from the group consisting of montan waxes, fatty acids and fatty acid amides, fatty alcohols of at least 12 carbon atoms and its ether derivatives thereof, paraffins, phthalic acid dicyclohexylester, phthalic acid monobenzyl ester, terephthalic acid dimethylester, polyacrylates, polymethacrylates and polyethylene waxes, said granules produced by (1) dissolving said optical brightener of finishing agent, alone or together with said dispersing agent or auxiliary, in said melt of organic carrier. (2) emulsifying said melt in water which is at a temperature of at least 90° C. with the aid of an emulsifier. (3) cooling the resulting emulsion with stirring, to produce a dispersion of said non-dusty, free flowing granules, in the aqueous emulsifying liquid, and (4) separating said non-dusty, free flowing granules from said aqueous emulsifying liquid.
