Kemsurf ESD is an excellent detergent, it does not show a loss of detergency in brine or hard water. The good solubility characteristics make them especially useful for use in alkaline liquid formulations. It is excellent foaming agent. It shows a pronounced thickening with the addition of sodium chloride to a dilute solution. It is stable to hard water and has excellent lime soap dispersing properties, due to the calcium salt being soluble. Product is prone to hydrolysis in aqueous solution at acid pH and high temperatures (not suitable for use above 50°C).
