Nonionic surface-active agents
Journal of Colloid and Interface Science, 1973Abstract The thermodynamic quantities associated with micellization have been measured for polyoxyethylene (23) lauryl alcohol in water/dioxane and water/ethanol solvents, by determination of the effect of temperature on the critical micelle concentration.

Surfactants are characterized by their ability to reduce the surface tension of aqueous fluids; this enables them to act as detergents, wetting agents, emulsifiers. James (1965) has defined them as molecules with two different structural elements, one being a hydrophobic hydrocarbon (water-repellent) group, and the other a hydrophilic polar (water ...

Surface-active agents, or surfactants, owe their name to their interesting behavior at surfaces and interfaces. They are positively adsorbed at interfaces between phases, and the adsorption of surfactant lowers the interfacial tension between the phases (see Chapter 8).

Surface-active agents as ointment bases*
Journal of the American Pharmaceutical Association (Scientific ed.), 1946Abstract A study of nine water‐miscible or water‐dispersible ointment bases is reported. Selected surface‐active agents were compounded to produce pharmaceutically acceptable ointment bases, and their irritant effects on intact human skin were determined.

Cataracts induced by surface active agents
Experimental Eye Research, 1974Abstract Intravitreally-administered anionic, cationic and neutral surface active agents are all capable of producing cataracts. The developing cataracts are characterized by increased hydration, loss of dry weight, progressive increases in Na + concentration, and progressive decreases in K + concentration.

Fat-Derived Surface-Active Agents [PDF]
Chemical & Engineering News Archive, 1949 POLYETHYLENE OXIDE derivatives of fatty amines, fatty amides and fatty acids are available in commercial quantities from the Armour Chemical Division under the trade names Ethomeens. Ethomids and Ethofats. Ethomeens are tertiary amines having one fatty alkyl group and two polyoxyethylene groups substituted on amino nitrogen : Ethomids are ...
