Butylated Hydroxyanisole USP
Butylated hydroxyanisole (BHA) is an antioxidant consisting of a mixture of two isomeric organic compounds, 2-tert-butyl-4-hydroxyanisole and 3-tert-butyl-4-hydroxyanisole. It is prepared from 4-methoxyphenol and isobutylene.
It is a waxy solid used as a food additive with the E number E320. The primary use for BHA is as an antioxidant and preservative in food, food packaging. BHA is particularly useful in protecting the flavors and color of essential oils and is considered the most effective of all food-approved antioxidants for this application. BHA is particularly effective in controlling the oxidation of short-chain fatty acids, such as those found in coconut and palm kernel oils that are used typically in cereal and confectionary products.
