Description

Myristyl Gallate is a synthetic ester of gallic acid and myristyl alcohol, functioning as a versatile phenolic antioxidant and stabilizer. Its primary value lies in its ability to inhibit oxidative degradation, thereby extending the shelf life and maintaining the integrity of sensitive formulations. This compound is essential for manufacturers in the cosmetics, personal care, and polymer industries who require effective protection against rancidity and color change.

Application

• Cosmetic & Personal Care Antioxidant: Used in creams, lotions, lipsticks, and sunscreens to prevent oxidation of oils and fats, preserving product efficacy and scent.
• Polymer & Plastic Stabilizer: Acts as an antioxidant in polyolefins (e.g., polyethylene, polypropylene) and other polymers to prevent thermal and oxidative degradation during processing and service life.
• Food Contact Material Additive: Employed in packaging materials to prevent the migration of oxidized compounds and protect food quality.
• Industrial Grease & Lubricant Stabilizer: Inhibits oxidation in synthetic and mineral oil-based lubricants, enhancing their operational lifespan.
• Adhesive & Sealant Formulations: Protects adhesive properties by preventing oxidative cross-linking or degradation of the base resins.
• Rubber Antioxidant: Helps in retarding the aging process of synthetic rubbers, maintaining elasticity and mechanical properties.
