Butylated Hydroxyanisole (BHA)

Butylated Hydroxyanisole (BHA) is a synthetic, waxy, solid petrochemical. Widely used as preservative in a variety of food, cosmetics, pharmaceuticals, and even rubber. BHA has been used in food to help prevent rancidification in fats and fat-containing foods, which can lead to unpleasant odors. Studies have suggested BHA to be a human carcinogen based on evidence from animal studies.
