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.

Activity of Nonionic Surfactants
Russian Journal of Applied Chemistry, 2001The 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.

Nonionic Fluorosilicone Surfactants
Journal of Colloid and Interface Science, 1993Abstract New fluorosilicone surfactants have been prepared. The focus has been on branched disiloxane and trisiloxane hydrophobes having 3,3,3-trifluoropropyl and 3,3,4,4,5,5,6,6,6-nonafluorohexyl radicals with poly(oxyethylene) hydrophiles. Their performance as aqueous surfactants was evaluated and compared to conventional methylsiloxane surfactants

Adsorption and micellar properties of a mixed system of nonionic–nonionic surfactants
Journal of Colloid and Interface Science, 2005We study the surface adsorption and bulk micellization of a mixed system of two nonionic surfactants, namely, ethylene glycol mono-n-dodecyl ether (C12E1) and tetraethylene glycol mono-n-tetradecyl ether (C14E4), at different mixing ratios at 15 degrees C.

Biodegradation of nonionic surfactants
Journal of the American Oil Chemists' Society, 1984AbstractThis paper discusses the biodegradability of alcohol‐based nonionics measured by the recommended legislative test procedures and how the results obtained are affected by the chemical structure of the surfactant, and thus provides guidance on the selection of materials.

A quantitative structure property relationship; QSPR was preformed as a means to predict critical micelle concentration of nonionic surfactants via correlating properties to parameters calculated from molecular structure. Such parameters; molecular weight, M w , hydrophobic‐hydrophilic fragments molecular weight ratio, χ, polarizability, α, partition ...

A Nonionic Surfactant and Blood Viscosity
Archives of Surgery, 1973Poloxamer 188, (Pluronic F68), a nonionic surface active agent, was investigated for its effect on blood viscosity. Ten dogs were given poloxamer 188 prior to, during, and after one hour of total cardiopulmonary bypass. Viscosity measurements were compared in control and treated animals perfused for 6 and 12 hours.
