Non-ionic surfactants are surfactants whose main hydrophilic group is the ether group that does not dissociate in aqueous solution, and whose surface activity is reflected by neutral molecules. Non-ionic surfactants have high surface activity, good solubilization, washing, antistatic, calcium soap dispersion, and other properties, with low irritation, and excellent wetting and washing functions. WITSCHEM supplies excellent non-ionic surfactants from BASF, Dow Chemical, PANASIA, and other brands.
