Synergism in Binary Mixture of Surfactants

Mixed Micellization of Dimeric (Gemini) Surfactants and Conventional Surfactants. I. Mixtures of an Anionic Dimeric Surfactant and of the Nonionic Surfactants C12E5and C12E8

“…Since SDS is close to types of systems reflect (i) the higher aggregation number of being the ''monomer'' of Dim1, the results suggest that C 12 E 5 micelles with respect to C 12 E 8 and Dim1 micelles; (ii) nonideality becomes less pronounced in going from a con-the higher cloud temperature of C 12 E 8 (about 77ЊC) with ventional (monomeric) surfactant to its corresponding di-respect to C 12 E 5 (about 32ЊC (36)); and (iii) the opposite meric surfactant. A similar behavior has been reported by temperature dependences of N for Dim1 and nonionic surfacRosen et al (13) and attributed to a steric inhibition of tants micelles (see Figs. 6 and 7).…”

Interactions between Quaternary Ammonium Surfactant Oligomers and Water-Soluble Modified Guars

“…Mixtures of conventional surfactants and surfactant dimers have been investigated in view of assessing the possible use of surfactant dimers in formulations (11)(12)(13)(14). The results showed synergism in mixed micellization in mixtures of surfactant dimers and nonionic ethoxylated surfactants (11,14).…”
