Description

Undeceth-5 is a non-ionic surfactant belonging to the alcohol ethoxylate family, derived from a C11 synthetic fatty alcohol chain and an average of 5 moles of ethylene oxide. This structure provides an effective balance between hydrophilic and lipophilic properties, making it a versatile intermediate and emulsifier. It is essential for formulators in industries such as agrochemicals, textiles, and industrial cleaning, where reliable wetting, emulsification, and dispersion are critical for product performance.

Application

• Primary emulsifier and wetting agent in agricultural formulations (e.g., herbicides, insecticides).
• Key intermediate for the synthesis of sulfated and phosphated derivatives used in specialty surfactants.
• Detergent and scouring agent in textile processing for fiber wetting and oil removal.
• Emulsifier and dispersant in industrial and institutional (I&I) cleaning products.
• Co-emulsifier and coupling agent in metalworking fluids and lubricants.
• Raw material for producing personal care surfactants with mild foaming properties.
