Web2 jan. 2024 · In order to combat free radicals, BHT functions as a synthetic analog of vitamin E. Similar to vitamin E, BHT prevents autoxidation. Autoxidation is a process whereby unsaturated organic compounds are attacked by atmospheric oxygen. This can cause changes in color, texture and efficacy of your product. BHT prevents this from occurring.
