Description

Anoxomer is a high-molecular-weight, polymeric antioxidant specifically designed for the stabilization of various materials against oxidative degradation. Its primary value lies in its ability to effectively inhibit the formation of free radicals, thereby extending the shelf life and maintaining the quality of finished products. This makes it a critical additive for manufacturers in the food, cosmetic, and polymer industries seeking reliable, non-volatile antioxidant solutions.

Application

• As a food-grade antioxidant in edible oils, fats, and fat-containing food products to prevent rancidity.
• As a stabilizing agent in cosmetics and personal care formulations, such as creams, lotions, and lipsticks, to protect active ingredients and base materials.
• As an antioxidant in pharmaceutical preparations to enhance the stability of active pharmaceutical ingredients (APIs) and excipients.
• As an additive in polymer and plastic manufacturing to prevent thermal and oxidative degradation during processing and in the final product.
• As a stabilizer in adhesives, sealants, and lubricants to improve their performance longevity.
• In animal feed to preserve nutritional quality by preventing fat oxidation.

Quality Control

Our Anoxomer is produced and tested under a strict quality management system. Each batch is analyzed to ensure it meets relevant specifications for its intended application, such as Food Chemical Codex (FCC) guidelines for food-grade material. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after initial use to minimize exposure to atmospheric moisture.
