What is Butylated Hydroxyanisole?
Butylated Hydroxyanisole (CAS 25013-16-5), commonly known as BHA or E320, is a synthetic phenolic antioxidant. Also approved under E320 and FEMA 2183.
Where is Butylated Hydroxyanisole used?
- Food: prevents oxidative degradation in fats, oils and lipid-containing formulations, extending shelf life
- Edible fats, oils, snack foods and packaging materials where fat oxidation is a primary spoilage concern
- Cosmetics and personal care: incorporated into creams and lotions to stabilize oil-phase ingredients against rancidity
- Pharmaceuticals: protects lipid excipients and active ingredients in oral and topical dosage forms
- Plastics, rubber and lubricants: processing stabilizer that protects polymer matrices and petroleum-based fluids from oxidative breakdown
Commercial specifications
- Purity levels of 98.5% and above are standard for regulated food and pharmaceutical supply chains
- Food-grade specifications conforming to FCC, BP and Ph. Eur. standards
