Product Description
Antioxidants are a diverse class of compounds, typically appearing as white to off-white powders, granules, or clear liquids, depending on the specific chemical. They are generally non-corrosive and non-alkaline, with a neutral pH. Solubility varies: many are soluble in organic solvents (such as acetone or methylene chloride) but insoluble in water. Antioxidants are stable under normal storage conditions and are designed to prevent or slow oxidation in a wide range of materials, including food, polymers, fuels, and biological samples.

Application Sectors and Industries of Antioxidants
Food & Beverage
Antioxidants are essential in food preservation, slowing the oxidation of fats and oils to prevent rancidity and extend shelf life. They maintain color, flavor, and nutritional quality in processed foods and beverages.
Pharmaceuticals
Used to stabilize active pharmaceutical ingredients (APIs) and formulations, antioxidants prevent degradation caused by oxidation. They enhance the stability and efficacy of vitamins, injectable solutions, and ointments.
Cosmetics & Personal Care
Antioxidants protect creams, lotions, and serums from oxidative spoilage. They also help safeguard the skin from free radicals, contributing to anti-aging and protective formulations.
Polymers & Plastics
Added to polyethylene, polypropylene, and other polymers, antioxidants prevent oxidative degradation during processing and end-use. This extends the lifespan and performance of plastic products.
Rubber & Elastomers
Antioxidants are used in natural and synthetic rubbers to inhibit cracking, discoloration, and loss of elasticity caused by heat and oxygen exposure, especially in tires, seals, and hoses.
Lubricants & Fuels
They prevent gum and varnish formation in fuels and oils, improving storage stability and engine performance. Antioxidants are critical for automotive, aviation, and industrial lubricants.
Paints & Coatings
Antioxidants enhance the shelf life and color retention of paints, varnishes, and coatings by inhibiting oxidative reactions that cause yellowing and degradation.
Agriculture
In agrochemicals and animal feeds, antioxidants preserve the potency of vitamins and nutrients, improving shelf life and efficacy in the field.
Analytical & Research Applications
Antioxidants are used in laboratory assays to protect biological samples from oxidative damage during analysis, ensuring accurate results in research and diagnostics.
Textile Industry
They prevent discoloration and degradation of fibers during manufacturing and storage, maintaining fabric quality and durability.
Packaging Types
- 25 kg Bags: Moisture-resistant packaging for powdered antioxidants, suitable for bulk industrial use.
- 200 kg Drums: Sealed steel or HDPE drums for liquid or granular forms, ensuring safe transport and storage.
- IBC Totes (1,000 liters): For large-scale users requiring bulk antioxidant solutions.
- Small Containers (1–5 kg): For research, laboratory, or specialty applications, with tamper-evident seals.
- Custom Packaging: Available for specialty grades or customer-specific requirements, including pre-measured sachets and sample kits.
Antioxidants are indispensable across industries for their ability to inhibit oxidation, preserve product integrity, and extend shelf life. Their versatility and effectiveness make them a cornerstone in food, pharmaceutical, polymer, and industrial applications.
