Description

Octadecanamide, n-Ethyl- is a high-purity, long-chain fatty acid amide derivative, also known as N-Ethyloctadecanamide. This compound serves as a versatile intermediate and functional additive, valued for its hydrophobic and slip properties. It is primarily utilized in the formulation of industrial lubricants, polymer processing aids, and personal care products where surface modification and release characteristics are critical.

Application

• As a slip agent and anti-blocking agent in polyolefin films and plastic processing.
• As a lubricant and mold release agent in the manufacturing of plastics, rubber, and synthetic fibers.
• As a waterproofing agent and hydrophobic modifier in coatings, textiles, and paper treatments.
• As a viscosity modifier and gelling agent in greases and specialty lubricant formulations.
• As a emollient and opacifying agent in cosmetic and personal care products like creams and lotions.
• As a chemical intermediate for the synthesis of more complex surfactants and quaternary ammonium compounds.
