Used as a non-ionic surfactant in industrial and specialty applications due to its excellent solubility in water and stability over a wide pH range. Commonly applied in emulsion polymerization as a stabilizer, helping to control particle size and improve latex stability. Also used in personal care formulations to enhance wetting and foaming properties. Its long ethylene oxide chain provides good compatibility with aqueous systems and helps reduce surface tension. Frequently found in cleaning products, textile processing, and as a dispersing agent for pigments and fillers in coatings and construction materials.
