Abstract:

This study presents properties and performance evaluations for branched nonionic surfactant structures in industrial & institutional (I&I) laundry. The effect of branching and oligomer distribution on the physical properties and washing performance were studied. Known methods were used to measure properties like IFT, foam, wetting, and dynamic surface tension. Cleaning performance was evaluated using a variety of soils on natural and synthetic fabrics. Branching and narrower oligomer distribution brings various benefits to I&I laundry including lowering the solidification point which enhance handling and dosing. Narrow oligomer distribution reduces the interfacial tension between oil and water helping increase soil solubilization and removal efficiency.
