Abstract: The invention relates to a method for the production of powdery preparations containing diethylamino-hydroxybenzoyl-hexyl-benzoate of formula (I), by: a) dispersing the benzoylbenzoate I in an aqueous molecular dispersed or colloidally dispersed solution of a protective colloid and b) transforming t he formed dispersion into a dried powder by separating the water and, optionall y, used solvents and by drying. The method is characterised in that modified starch is used as a protective colloid in step (a).
