Description

Octadecanoic Acid 2-(Hexadecyloxy)Ethyl Ester is a high-purity synthetic ester derived from stearic acid and a long-chain ethoxylated alcohol. This compound is valued for its excellent lubricity, stability, and hydrophobic properties, making it a versatile intermediate and functional additive. It is primarily used by formulators in the personal care, cosmetics, and specialty lubricants industries seeking high-performance emollients and non-ionic surfactants.

Application

• As a premium emollient and skin-conditioning agent in cosmetic creams, lotions, and sun care products.
• Functioning as a co-emulsifier and viscosity modifier in personal care formulations.
• Used as a lubricant and processing aid in the production of plastics and synthetic fibers.
• Acting as a waterproofing agent and release agent in various industrial coatings and mold release applications.
• Serving as a key intermediate for the synthesis of more complex specialty esters and surfactants.
• Potential use as a textile softener and finishing agent to impart a smooth hand feel.
