Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-2-(Dodecylthio)Ethyl-.Omega.-Hydroxy- is a specialized nonionic surfactant belonging to the class of thioether-terminated polyethylene glycol derivatives. This compound is valued for its unique combination of hydrophilic polyether chains and a hydrophobic dodecylthioether tail, offering excellent emulsifying, dispersing, and stabilizing properties. It is a critical performance additive for formulators in the lubricant, polymer, and specialty chemical industries seeking to enhance product compatibility and surface activity.

Application

• Lubricant & Grease Additive: Acts as an extreme pressure (EP) additive, anti-wear agent, and stabilizer in synthetic and semi-synthetic lubricating oils and greases.
• Polymer Industry: Used as an internal or external lubricant and processing aid in PVC, polyolefins, and engineering plastics to improve flow and mold release.
• Emulsion Stabilizer: Functions as a co-emulsifier and stabilizer in oil-in-water (O/W) emulsions for agricultural, textile, and industrial formulations.
• Metalworking Fluids: Serves as a key component in cutting, grinding, and drawing fluids, providing lubrication and rust inhibition.
• Surface Treatment: Employed in coatings and surface modifiers to improve wetting, leveling, and adhesion on various substrates.
• Chemical Intermediate: Utilized in the synthesis of more complex surfactants and functional polymers due to its reactive terminal hydroxyl group.
