• Food Industry: Antioxidant (E310) for edible oils, fats, meat products, baked goods, and instant noodles; prevents lipid oxidation and extends product shelf life.
• Pharmaceutical Industry: Stabilizer for drug formulations containing oils or fats; antioxidant for active pharmaceutical ingredients (APIs) susceptible to oxidation.
• Cosmetics Industry: Preservative and antioxidant in skincare, haircare, and lip care products; protects oils and fragrances from rancidity.
• Industrial Field: Antioxidant for lubricants, plastics, and rubber products; inhibits oxidative degradation during storage and use.

• Storage Conditions: Store in a cool, dry, well-ventilated warehouse at 0–25 °C. Protect from direct sunlight, heat sources, and moisture. Seal the package tightly to avoid contact with air.
• Handling Precautions: Wear protective gloves, goggles, and a dust mask during operation. Avoid inhalation of dust and contact with eyes, skin, and mucous membranes. In case of contact, rinse the affected area with plenty of water immediately.

• Stability: Stable under normal storage conditions; prone to oxidation when exposed to heat, light, or alkaline environments.
• Incompatibility: Avoid contact with strong oxidizing agents, alkalis, and heavy metal ions (e.g., Fe³?, Cu²?), which may accelerate degradation.
• Hazardous Decomposition Products: Carbon monoxide (CO) and carbon dioxide (CO?) under high-temperature combustion conditions.

• Food Grade: Complies with FCC (Food Chemicals Codex), EU E310 and GB 2760 standards.
• Pharmaceutical Grade: Meets USP (United States Pharmacopeia) and EP (European Pharmacopoeia) specifications.
• Industrial Grade: Conforms to industry standards for antioxidant applications in lubricants and polymers.

• Standard Packaging: 25 kg net weight in polyethylene-lined kraft paper bags or fiber drums; 1 kg, 5 kg in food/pharma-grade aluminum foil bags for small batches.
• Custom Packaging: Available upon customer request.

• Hazard Classification: Non-hazardous chemical (not regulated as dangerous goods for transportation).
• Transport Precautions: Prevent package breakage and moisture absorption during transit. Avoid mixing with strong oxidants and alkalis. Protect from sunlight and high temperatures during transportation.

1. For high-temperature processed foods (e.g., fried goods, baked products), prioritize BHT or propyl gallate for their thermal stability.
2. For natural/organic food products, choose tocopherols or ascorbyl palmitate to meet clean-label requirements.
3. For cost-sensitive industrial applications, BHT is the preferred economical option.
4. To maximize antioxidant efficacy, use compound formulations (e.g., propyl gallate + citric acid) instead of single antioxidants.
