Do not contain any ions. These are actually esters of high molecular mass alcohols obtained either by reaction between polyethylene glycol and stearic acid, (e.g., polyethylene glycol stearate) or by reacting long chain alcohols such as lauryl alcohol with excess of ethylene oxide in presence of a base (e.g., lauryl alcohol ethoxylate). Liquid dishwashig detergents contain non-ionic detergents.
