Description

Dodecaethylene Glycol Monobenzyl Ether is a high-purity, non-ionic surfactant and chemical intermediate characterized by its long polyoxyethylene chain and terminal benzyl group. This structure provides excellent solubility properties, making it a valuable component for formulating stable emulsions and modifying surface characteristics. It is primarily utilized in advanced material science, specialty polymer synthesis, and high-performance industrial formulations where precise control over hydrophilicity and reactivity is required.

Application

• As a non-ionic surfactant and emulsifier in specialty coatings, inks, and agrochemical formulations.
• As a chemical building block for synthesizing complex polymers and dendrimers with tailored properties.
• As a phase transfer catalyst or solubilizing agent in organic synthesis and pharmaceutical intermediate manufacturing.
• As a surface modifier in nanoparticle synthesis and dispersion to control particle size and stability.
• In the research and development of advanced materials, including liquid crystals and conductive polymers.
• As a key intermediate for producing specialized silicone and polyether-based additives.
