Abstract
Benzotriazole UV absorbers substituted with an ultra long ester or amide moiety wherein the ester or amide group is a hydrocarbyl group of 25 to 100 carbon atoms or is a group of alkyl of 25 to 100 carbon atoms interrupted by 5 to 39 oxygen atoms and terminated with an omega—OH or an omega—OR group exhibit excellent stabilization efficacy while they concomitantly do not bloom when incorporated into polyolefin films. These benzotriazole UV absorbers also provide excellent protection to white, dyed, dipped, unscented and/or scented candle wax from discoloration and degradation.
