Description

Isooctyl Gallate is a synthetic ester of gallic acid, widely recognized as an effective antioxidant and stabilizer. Its primary value lies in its ability to inhibit oxidative degradation, thereby extending the shelf life and maintaining the integrity of various industrial products. This compound is essential for manufacturers in the plastics, rubber, food packaging, and personal care industries seeking to protect their formulations from premature aging and discoloration.

Application

• Primary antioxidant and stabilizer in polyolefins (e.g., polyethylene, polypropylene) and synthetic rubbers.
• Food-contact material additive for plastics and adhesives to prevent oxidative rancidity.
• Stabilizing agent in cosmetics and personal care products, such as creams and lotions.
• Intermediate in the synthesis of other specialty chemical additives and pharmaceutical compounds.
• Protective additive for fuels and lubricants to enhance oxidative stability.
• Used in adhesives and sealants to improve thermal aging resistance.

Quality Control

Our Isooctyl Gallate is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications for industrial and specialty applications. Certificates of Analysis (COA) documenting purity, physical properties, and conformance are provided with every shipment to guarantee supply reliability and performance consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This material is light-sensitive and easily oxidized; prolonged exposure to air, heat, or light should be avoided to maintain product efficacy. For long-term storage, consider an inert atmosphere.
