Abstract

Hindered amine compounds which are substituted by a long hydrocarbon chain are useful in a number of applications where the solubility or compatibility afforded by said substitution is needed. This is seen particularly for example with white, dyed, dipped, unscented and/or scented candle wax which is effectively stabilized against discoloration and fading by the incorporation therein of a long chain hindered amine alone or in combination with a UV absorber and/or an antioxidant.
