Nonionic Surfactants: An Overview
Tenside, Surfactants, Detergents, 2010Abstract Nonionic surfactants do not produce ions in aqueous solution. As a consequence, they are compatible with other types of surfactants and are excellent candidates to enter complex mixtures, as found in many commercial products. Nonionic surfactants are found today in a large variety of domestic and industrial products, such as ...

Clouding of nonionic surfactants
Current Opinion in Colloid & Interface Science, 2016Nonionic surfactants have broad applications such as cleaning and dispersion stabilization, which frequently are hampered by strong temperature sensitivities. As manifested by clouding and decreased solubility with increasing temperature, the interaction between water and the oligo(oxyethylene) head-groups is becoming less favorable.

Preparations of organobentonite using nonionic surfactants
Chemosphere, 2001Due to hydrophilic environment at its surface, natural bentonite is an ineffective sorbent for nonpolar nonionic organic compounds in water even though it has high surface area. The surface properties of natural bentonite can be greatly modified by simple ion-exchange reactions with large organic cations (cationic surfactants) and this organobentonite ...

Abundant oxygen-containing functional groups make lignite high moisture content, which reduces the utilization efficiency of lignite. The decrease in hydrophilicity of lignite surface can be achieved by treating with surfactant.
