Surface-active agents nonionic

Nonionic Surface-Active Agents. Approximately 14% of the ethyleae oxide consumed ia the United States is used in the manufacture of nonionic surfactants. These are derived by addition of ethylene oxide to fatty alcohols, alkylphenols (qv), tall oil, alkyl mercaptans, and various polyols such as poly(propylene glycol), sorbitol, mannitol, and cellulose. They are used in household detergent formulations, industrial surfactant appHcations, in emulsion polymeri2ation, textiles, paper manufacturing and recycling, and for many other appHcations (281).

A great number of nonionic surfactants have been ethoxylated and subsequently reacted with P4O10. The acid phosphate esters from this reaction possess surface properties and detergency similar to the nonionic surface-active agents employed as reactants. Detergency tests and foam heights from the Ross-Miles method have been reported for a series of compounds. Various formulations for all-purpose cleaners are given as well [37,40,41,44,48]. [Pg.599]

Alkanolamides are nonionic surface active agents that hnd application in a multitude of uses. There are four major groups of fatty alkanolamides (1) mono-ethanolamides (MEA), (2) diethanolamides (DEA), (3) monoisopropanolamides (MIPA), and (4) ethoxylated or PEG alkanolamides. Each group has its own specific functions and uses in formulations. [Pg.3019]

A systematic study of the influence of salts on foam films formed from nonionic surface active agents was carried out in these laboratories (3, 6). This paper reports an investigation of the effects of sodium chloride and potassium thiocyanate on the thickness of foam films formed from DMS. In addition to measurements on films, the electrophoretic mobilities of dodecane droplets stabilized with DMS were determined as a function of salt concentration, and the properties of insoluble mono-layers of octadecylmethyl sulfoxide (OMS) at the air-water interface have been examined using the classical methods largely developed by N. K. Adam (7). [Pg.93]

Alkanolamides are condensation products of fatty acids with primary or secondary alkanolamines (Feairheller et al., 1994 Kopylov et al., 1980 Maltby Read, 2000). These products are nonionic surface-active agents and find application in a multitude of uses including dry-cleaning soaps, fuel-oil additives, rust inhibitors, textile scouring, and dye-leveling agents.
