Description

Oxirane, Methyl-, Polymer With Oxirane, Monopentadecylether is a specialized nonionic surfactant belonging to the class of polyoxyethylene-polyoxypropylene block copolymers, specifically functionalized with a long-chain monopentadecyl ether group. This unique structure provides a critical balance of hydrophilic and lipophilic properties, making it an essential performance additive for demanding industrial formulations. It is particularly valued in sectors requiring stable emulsification, effective wetting, and controlled rheology under challenging conditions.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a key surfactant and emulsifier in heavy-duty degreasers, metal cleaners, and floor care products, effectively removing oils and greases.
• Textile Processing: Used as a dyeing assistant, leveling agent, and lubricant to ensure uniform color uptake and reduce fiber breakage during manufacturing.
• Agrochemical Formulations: Serves as an emulsifier and dispersant in pesticide and herbicide concentrates, enhancing sprayability and active ingredient stability.
• Paints & Coatings: Functions as a pigment wetting agent and dispersant, improving color development, gloss, and stability in water-based and solvent-based systems.
• Personal Care & Cosmetics: Employed as an emulsifier and solubilizer in creams, lotions, and hair care products, providing a smooth texture and stable emulsions.
• Polymerization: Can be utilized as a surfactant in emulsion polymerization processes for the production of synthetic rubbers, latexes, and plastics.
