“…The combination of an oil-soluble surfactant and a watersoluble surfactant is often successful. According to Elworthy et al,12) the presence of the oil-soluble surfactant increases lateral interactions between adsorbed molecules in the film, thereby making it stronger and more condensed. Boyd et aIY·14) suggested that the stronger affinity of the polyethylenenated derivatives of Span 80 for water induced the Tween hydrophobic chain to be extended slightly into the aqueous dispersion medium, thus allowing the adsorbed molecules to pack together more closely at the oil/water interface.…”

“…Some higher fatty alcohols have been reported to be very useful as stabilizers of emulsions (1)(2)(3)(4)(5)(6)(7)(8)(9). Schulman and Cockbain (2) have found that the stability of Nujol-in-water emulsions increases markedly by an addition of cetyl alcohol, which results from a formation of intermolecular complexes with emulsifiers at oil-water interface.…”

Alkyl-2-pyrrolidone-5-carboxylates (R-PCA), the derivatives of higher alcohols, were prepared and their properties as emulsion stabilizers were estimated using surface tension meter and Multiple Drop methods in the presence of sodium dodecyl sulfate (SDS) and were compared to those of another system containing a series of the corresponding alcohols as stabilizers. The R-PCA system markedly reduced the interfacial tension compared to a higher alcohol system, and the interfacial tensions for both R-PCA and higher alcohol systems decreased with the increase of carbon chain length. The stability of oil drops increased greatly by addition of R-PCA compared to higher alcohol system. In the higher alcohol system, the stability of oil drop showed the minimum at carbon 12. In the R-PCA system, the stability of oil drops increased greatly with the increase of carbon chain length. A series of R-PCA was found to be useful as emulsion stabilizers.

“…The present authors (Elworthy, Florence & Rogers, 1971b) made a detailed investigation into the effect of cetyl alcohol on the stability of C,,E,-stabilized chlorobenzene emulsions. Although less surface-active than the mam detergent at the chlorobenzene-water interface the hexadecanol resulted in a definite increase in stability.…”
