The PEL-ALC TDA series of surfactants are 100% active, ethoxylated isotridecyl alcohol. The isotridecyl alcohol used is propylene tetramer converted to the corresponding oxo alcohol. Members of this group have excellent rapid wetting properties, are relatively low foaming and exhibit good detergency. They are used as emulsifiers, dispersants, solubilizers and as detergents. The lower members of the series, 3, 4 & 6 are dispersible in water and the rest are soluble in water at room temperature.
