Description

(E)-9-Octadecenamide, also known as oleamide, is a primary fatty acid amide of oleic acid. This compound serves as a crucial intermediate and functional additive in various industrial and research applications due to its surface-active and slip properties. It is particularly valued in the polymer, lubricant, and personal care industries for its ability to modify material characteristics and enhance performance.

Application

• Polymer Additive: Acts as an effective slip agent and anti-blocking agent in polyolefin films (e.g., LDPE, LLDPE) to improve surface smoothness and processing.
• Lubricant Formulation: Used as a friction modifier and corrosion inhibitor in synthetic lubricants and greases.
• Personal Care & Cosmetics: Functions as an opacifying agent, viscosity modifier, and emollient in creams, lotions, and hair care products.
• Biochemical Research: Studied for its role as an endogenous signaling molecule (a sleep-inducing lipid) in neurological and physiological research.
• Ink & Coating Industry: Employed as a dispersing agent and flow promoter to enhance the application properties and finish of coatings.
• Adhesive & Sealant Modifier: Improves the rheological properties and surface release characteristics of adhesive formulations.
