Description

2-(Octadecyloxy)Ethanol is a long-chain fatty alcohol ethoxylate, a non-ionic surfactant characterized by its hydrophobic octadecyl (stearyl) chain and hydrophilic ethoxylate group. This amphiphilic structure is critical for its function as an emulsifier, dispersant, and viscosity modifier in complex formulations. It is primarily utilized in industries requiring stable emulsions and surface activity, such as cosmetics, personal care, lubricants, and textile processing.

Application

• Cosmetic & Personal Care Formulations: Acts as a non-ionic emulsifier and opacifier in creams, lotions, and hair conditioners.
• Industrial Lubricants & Metalworking Fluids: Serves as a lubricity additive and emulsifier in oil-in-water systems.
• Textile Processing: Used as a softening agent, lubricant, and anti-static agent for fibers and yarns.
• Paint & Coating Additives: Functions as a dispersing agent for pigments and a flow control agent.
• Agricultural Adjuvants: Employed as a surfactant in pesticide and herbicide formulations to enhance spreading and adhesion.
• Plastic & Polymer Processing: Acts as an internal and external lubricant and anti-static agent.
