Applications
- Food Antioxidant (E321) A widely approved food-grade antioxidant that prevents oxidative rancidity in edible oils, fried foods, nuts, snacks and chewing gum. Extends shelf life while protecting flavor, color and nutritional quality in processed food products.
- Feed & Pet Food Preservation Protects fats and oils in animal feed and pet food from oxidation during storage and transport. Maintains feed freshness, palatability and nutritional value, supporting consistent animal performance in feed manufacturing.
- Plastics & Polymer Stabilization An efficient primary antioxidant for polyolefins, polystyrene, ABS and other polymers. Prevents thermal and oxidative degradation during processing and service, preserving mechanical strength, color and long-term durability of plastic products.
- Rubber & Elastomer Processing A cost-effective anti-aging agent for tires, rubber goods and elastomer compounds. Protects against oxygen, heat and flex-cracking, extending the service life of rubber products in demanding applications.
- Lubricants & Fuels A stabilizer for lubricating oils, greases and fuels, preventing oxidation, sludge and gum formation. Consistent quality and high thermal stability support reliable performance in automotive and industrial applications.
- Cosmetics An effective antioxidant for oil-based cosmetics, protecting sensitive ingredients from oxidative degradation.
Quality Assurance
Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.
Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
