Abstract: PROBLEM TO BE SOLVED: To produce a stable benzophenone imine free from a reverse reaction to form benzophenone during storage by distilling ammonia and also removing water using distillation or using non-distillation means from an effluent of a benzophenone imine reaction. SOLUTION: This method is composed of the processes distilling ammonia and removing water using distillation or using non-distillation means from an effluent of a benzophenone imine reactor generated by catalytic reaction of a benzophenone of the formula [R and R are independently a halogen, hydroxy, a 6-10C aryl, a 1-12C alkyl, etc.; (m) and (n) are each independently an integer of 0-5] and ammonia. The distillation is preferably carried out at 20-200 deg.C under a pressure of 1-1,000 mbar.

Abstract: Described are cosmetic preparations containing light-screening agents designed to protect the human epidermis against UV light in the region from 280 to 400 nm. The light-screening agents are contained in a carrier compound suitable for cosmetic purposes together with compounds of the formula (I), as given in claim 1, in which R , R and n are as defined in clause 1, which absorb in the UV-B region and are per se prior art for cosmetic preparations, in amounts which are active as photostable UV-A filters.
