Description

5-Dodecylbenzene-1,3-Diol is a synthetic alkylated resorcinol derivative, a member of the phenolic antioxidant class. This compound is valued for its ability to inhibit oxidation and act as a radical scavenger, thereby extending the service life and stability of various materials. It is primarily utilized by formulators and manufacturers in the polymer, lubricant, and specialty chemical industries seeking to enhance product durability and performance.

Application

• Polymer Stabilizer: Acts as an effective antioxidant and processing stabilizer for polyolefins (e.g., polyethylene, polypropylene), synthetic rubbers, and engineering plastics to prevent thermal and oxidative degradation.
• Lubricant & Grease Additive: Incorporated into industrial lubricants, hydraulic fluids, and greases to inhibit oxidation, reduce sludge formation, and extend oil change intervals.
• Fuel & Petrochemical Additive: Used as an antioxidant additive in fuels, transformer oils, and other hydrocarbon-based fluids to improve stability and shelf life.
• Cosmetic & Personal Care: Serves as a stabilizing agent and antioxidant in formulations where its phenolic structure provides protection against rancidity in oils and butters.
• Adhesive & Sealant Formulations: Enhances the aging resistance and long-term performance of adhesive and sealant products based on organic polymers.
• Chemical Intermediate: Utilized in the synthesis of more complex antioxidant molecules, UV absorbers, or other specialty chemicals.
