Overview
Butylated hydroxyanisole (BHA) is a widely used phenolic antioxidant, approved for food and feed applications. It is a mixture of two isomeric compounds, providing effective protection against oxidative rancidity in fats, oils, and lipid‑containing products. Its excellent oil solubility and thermal stability make it a reliable choice for preserving the quality and shelf life of a wide range of products.

Applications

• Food industry: Used as an antioxidant in edible oils, baked goods, snacks, cereals, chewing gum, and meat products to prevent oxidation and rancidity.

• Feed industry: Added to animal feed to protect vitamins, fats, and proteins from oxidative degradation, preserving nutritional value.

• Food packaging: Incorporated into packaging materials to prevent oxidation of the packaged food.

• Cosmetics and personal care: Used in lipsticks, creams, and oils to protect against oxidation.

• Industrial: Applied in rubber, plastics, and lubricants as a stabilizer.

Key Benefits

• High antioxidant activity – effective at low concentrations.

• Excellent oil solubility – easy to incorporate into lipid‑based systems.

• Heat stability – suitable for high‑temperature processing.

• Non‑staining – no discoloration in the presence of metal ions.

• Synergistic effect – enhances performance when combined with BHT, citric acid, or other organic acids.

• Antibacterial properties – provides mild antimicrobial protection.

• No off‑odor – does not impart unwanted odors to finished products.

Recommended Use

• Food: Typical concentration 0.01–0.1% by weight of total product.

• Feed: Maximum dosage generally 150 g per ton of feed (check local regulations).

• Synergy: Works best in combination with BHT and organic acids (e.g., citric acid, ascorbic acid).

Safety and Handling

• BHA is generally recognized as safe (GRAS) when used at approved levels.

• May cause mild skin or eye irritation; use appropriate personal protective equipment (gloves, safety goggles).

• Avoid inhalation of dust; handle in a well‑ventilated area.

• Store in a cool, dry, well‑ventilated area, away from direct sunlight, heat, and strong oxidizers.

• Keep containers tightly sealed to prevent contamination and degradation.
