Description

Isotridecyl Stearate is a high-performance synthetic ester derived from stearic acid and isotridecyl alcohol. This compound serves as a versatile and effective emollient, lubricant, and coupling agent, valued for its excellent oxidative stability and low volatility. It is a critical raw material for formulators in the personal care, lubricant, and polymer processing industries seeking to enhance product performance and skin feel.

Application

• As a high-performance emollient and skin-conditioning agent in cosmetic and personal care formulations such as creams, lotions, and sunscreens.
• Functioning as a lubricant and plasticizer in the processing of plastics, resins, and synthetic fibers to improve flexibility and reduce friction.
• Used as a viscosity modifier and coupling agent in industrial lubricants, greases, and metalworking fluids.
• Acting as a texturizer and gloss enhancer in hair care products and color cosmetics.
• Serving as a carrier and solvent for active ingredients in topical pharmaceutical and agrochemical preparations.
• Employed as a release agent and mold lubricant in rubber and plastic molding operations.
