Tween™ series surfactants are polyoxyethylene derivatives of the SPAN™ series products. Tween™ surfactants are hydrophilic, generally soluble or dispersible in water, and soluble in varying degrees inorganic liquids. They are used for oil-in-water (O/W) emulsification, dispersion or solubilization of oils, and wetting. Frequently, Tween™ surfactants are combined with similarly numbered SPAN™ surfactants to promote emulsion stability. These products are widely used in personal care, fiber finish, HI&I cleaning, crop protection, paints & coatings, adhesives, and other industrial applications.
