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).

Abstract: The present invention relates to particulate, linear, sheet-like, or three-dimensional structures which comprise, at least on their surface, a hydrophilicizing amount of at least one polymer which has urethane groups and/or urea groups, and also ammonium groups. The ammonium groups are obtained by quaternizing or neutralizing tertiary amino groups, preferably with carbonic acid.
