Description

Oxirane, Methyl-, Polymer With Oxirane, Hexadecyl Octadecyl Ether is a high-performance, nonionic surfactant belonging to the class of polyalkylene glycol alkyl ethers. This versatile chemical is engineered to provide exceptional emulsification, wetting, and dispersion properties in demanding formulations. It is a critical additive for manufacturers in the coatings, agrochemical, textile, and personal care industries seeking to improve product stability and performance. The compound is supplied under CAS No. 68409-58-5.

Application

• Coatings & Inks: Acts as a highly effective pigment dispersant and grinding aid, improving color development and stability in solvent-based and high-solids coatings.
• Agrochemical Formulations: Used as an emulsifier and stabilizer in pesticide and herbicide concentrates (EC, SC, EW), enhancing tank-mix compatibility and spray performance.
• Textile Processing: Serves as a leveling agent, lubricant, and anti-static agent in fiber production and dyeing processes.
• Industrial Cleaners & Degreasers: Provides powerful wetting and emulsification for heavy-duty cleaning formulations, effectively removing oils and greases.
• Metalworking Fluids: Functions as a lubricity additive and emulsifier in synthetic and semi-synthetic coolants and drawing compounds.
• Personal Care: Employed as an emulsifier and solubilizer in cosmetic creams, lotions, and hair care products, though specific grade compliance must be verified.
• Polymerization: Can be used as a surfactant or stabilizer in emulsion polymerization processes for synthetic rubbers and plastics.
