BHT

BHT (Butylated Hydroxytoluene) is a synthetic chemical used as an antioxidant in many food, cosmetic, and packaging products. Its primary role is to prevent fats and oils from spoiling or becoming rancid by stopping the chemical reactions that cause spoilage. This helps extend the shelf life of products. While generally considered safe in small amounts, some people prefer to avoid BHT due to concerns about potential health effects, and regulatory agencies set limits on its use to ensure safety.
