Nonionic surfactants do not ionize in water and are amphiphilic with hydroxyl (OH) or ether bond (R-O-R ') as the hydrophilic group
Non-ionic surfactant structure molecules, because of the weak hydrophilicity of hydroxyl and ether bonds, so the molecule must contain
multiple such groups - to show a certain hydrophilicity, which is very different from the anionic and cationic surfactants that can play a
hydrophilic role with only one hydrophilic group. It is precisely because the non-ionic surfactant has the characteristics of non-ionization in water,
which determines that it is superior to the ionic surfactant in some aspects, such as better solubility in water and organic solvents, high stability in solution,
and not easily affected by strong electrolyte inorganic salts and acids and bases. Because of its good compatibility with other types of surfactants,
it can often be well mixed and used. Nonionic surfactants have good resistance to hard water and low foamability, so they are suitable for special detergents.
Because of its dispersion, emulsification, foaming, wetting, solubilizing properties, it has important applications in many fields
