Butylated Hydroxytoluene Bht

Butylated hydroxytoluene (BHT) is a synthetic antioxidant that prevents or slows the deterioration of products like cosmetics, foods, and plastics by neutralizing free oxygen radicals. It's a white crystalline powder, soluble in oils and alcohol but not water, and is used to extend shelf-life and stabilize the color of various products. While it's widely used, some studies have raised concerns about its safety at high doses, leading to ongoing research and the consideration of alternatives like Vitamin E and rosemary extract.
