The invention relates to a method for the production of powdery preparations containing 2.4.6-trianilino-p-(carbo-2'-ethylhexyl-1'-oxi)-1.3.5-triazine of formula (I), by a) dispersing the triazine (I) in an aqueous molecular dispersed or colloid dispersion solution of a protective colloid and b) transforming the formed dispersion into a dried powder by separating water and, optionally, additionally used solvent and by drying. The invention is characterised in that modified starch is used as a protective colloid in step (a).
