Butylated Hydroxyanisole

Butylated Hydroxyanisole (CAS 121-00-6), commonly known as BHA or E320, is a synthetic phenolic antioxidant used in food, cosmetic, and industrial manufacturing.

Where is Butylated Hydroxyanisole used?

• Food manufacturing: added to edible fats, oils, snack foods, and packaging materials to inhibit rancidity and meet regulatory requirements
• Cosmetic and personal care: incorporated into creams, lotions, and lip products to protect oil-phase ingredients from oxidative breakdown
• Industrial lubricants: stabilizes mineral oils and metalworking fluids against oxidation under high-temperature processing
• Plastics and polymer compounding: processing stabilizer protecting base resins during extrusion and molding
• It prevents oxidative degradation in fats, oils, and lipid-containing formulations.

Commercial specifications

• Purity levels of 98.5% and above are standard for food and cosmetic grades
• Food-grade specifications conforming to FCC, BP, and Ph. Eur. standards
• Technical grade options for industrial applications where high-purity food standards are not required
