بوتیل هیدروکسی انیزول

Butylated Hydroxy anisole (BHA) is a synthetic waxy solid composed of two isomeric organic compounds. It is widely used as an antioxidant in foods, food packaging, cosmetics, pharmaceuticals, animal feed, and petroleum-based products. It helps prevent oxidation and prolongs shelf life by protecting against spoilage caused by fats going rancid.
🏭⚗️ Production

BHA is produced by alkylating 4-methoxyphenol with isobutylene, resulting in a mixture of two isomers.
🧪 Applications

BHA is commonly used to preserve fats and oils in food products such as snacks, baked goods, and cereals. It is also found in personal care products like lipsticks and moisturizers, and in pharmaceuticals to prevent oxidation of active ingredients.
⚠️ Safety

BHA is generally recognized as safe when used within regulated limits. However, animal studies have shown potential carcinogenic effects at high doses, leading it to be classified as “possibly carcinogenic to humans.” Nonetheless, typical human exposure is considered safe by food and drug authorities.
