Abstract:
The invention relates to a method for the production of powdered preparations containing 2,4,6-trianilino-p-(carbo-2'-ethylhexyl-1'-oxi)-1,3,5-triazine of formula I and diethylamino-hydroxybenzoyl-hexyl-benzoate of formula II by a) jointly dispersing compounds I and II in an aqueous molecularly disperse or colloidally disperse solution of a protective colloid, and b) converting the obtained dispersion into a dry powder by eliminating the water and additionally used solvents, if applicable, and drying. The inventive method is characterized in that modified starch is used as a protective colloid in step a).
