Competitive Adsorption of Nonionic Surfactant and Nonionic Polymer on Silica

open access: yesLangmuir, 2007
Competitive adsorption of the nonionic polymer poly(ethylene oxide) (PEO) and the nonionic surfactant of the type poly(ethylene oxide) alkyl ether from aqueous solutions on a silica surface is examined. From one-component solutions, both species readily adsorb onto silica and, in the bulk of mixed (two-component) solutions, polymer-surfactant complexes

Interfaces Charged by a Nonionic Surfactant

open access: yesThe Journal of Physical Chemistry B, 2018
Highly hydrophobic, water-insoluble nonionic surfactants are often considered irrelevant to the ionization of interfaces at which they adsorb, despite observations that suggest otherwise. In the present study, we provide unambiguous evidence for the participation of a water-insoluble surfactant in interfacial ionization by conducting electrophoresis ...

Bending Elasticity of Nonionic Surfactant Layers

open access: yesLangmuir, 2009
A novel approach to evaluate the bending elasticity of monolayers formed by nonionic surfactants with a rigid head group is introduced by means of considering head group repulsion as derived from the free energy of mixing rigid hydrophilic head groups with surrounding solvent molecules as well as contributions related to the hydrophobic tails. Explicit

Nonionic surfactants

Journal of the American Oil Chemists' Society, 1978
AbstractOver one billion pounds of nonionic surface‐active agents are produced per year in the U.S. alone. The oxyethylene derivatives of alcohols and alkylphenols account for 71% of this production. Methods of making these surfactants, along with descriptions of their properties and main uses in various detergents, are described.

Clouding of nonionic surfactants

Current Opinion in Colloid & Interface Science, 2016
Nonionic 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.

Activity of Nonionic Surfactants

Russian Journal of Applied Chemistry, 2001
The surface activity of block copolymers of ethylene and propylene oxides, based on ethylenediamine, mono(ethylene glycol), and triethanolamine, was studied. Adsorption characteristics of the investigated compounds at the water-air interface are estimated.
