Abstract
Candle wax containing a combination of a UV absorber, preferably a benzotriazole, in combination with a hindered amine which is substituted on the N-atom by an alkoxy, a cycloalkoxy or an hydroxy-substituted alkoxy moiety is surprising better stabilized than candle wax which contains a combination of a UV absorber and a conventional hindered amine where the N-atom is substituted by hydrogen or alkyl.
