Abstract:

Adsorption and redn. of interfacial tension caused by adsorption of nonionic ethoxylated nonyl phenols were studied in emulsion. A method for estg. adsorption and interfacial tension in emulsion was developed. There is no correlation between values of interfacial tension as measured in emulsified and sepd. and sepd. oil-water systems. Yet, there seems to be a significant correlation between adsorption values as measured in emulsified and sepd. oil-water systems. The values of max. adsorption of the emulsifiers as measured in the sepd. oil-water system correlate linearly with HLB values of these emulsifiers. Such correlation may indicate possible dependence of HLB values on emulsifier adsorption to the interface. [on SciFinder(R)]
