What is the difference between ionic and nonionic surfactants Nonionic surfactant that does not generate ions in aqueous solution. Its dissolution in water is due to its strong affinity for water. Compared with anionic surfactants, ionic non ionic surfactants have a higher emulsifying ability and a certain resistance to hard water. It is an indispensable ingredient in detergent and emulsifier formulations. Of course, compared with anionic surfactants, non-ionic surfactants also have the disadvantages of limited cloud point, poor alkali resistance, and high price. ionic vs non ionic are mostly liquid and slurry, and their solubility in water decreases with increasing temperature. Non-ionic surfactants have various properties such as washing, dispersing, emulsifying, wetting, adding liquid, uniform dyeing, antiseptic, protective colloid and so on. Widely used in textile, paper, food, plastic, leather, fur, glass, petroleum, chemical fiber, medicin...
