Reliable aggregation numbers are obtained for polyelectrolyte bound cationic micelles using fluorescence quenching with a cationic surfactant quencher
Article Abstract:
Surfactant quenchers with properties similar to the cationic surfactant dodecyltrimethylammonium bromide offer significant advantages over the more conventional quenchers. It is a benefit that the quencher and the surfactant are similar in their interactions with each other and with the polyelectrolyte.

Mixed solutions of surfactant and hydrophobically modified polymer. Controlling viscosity with micellar size
Article Abstract:
A higher viscosity may be regained by changing the stoichiometry between polymer hydrophobic tails and mixed micelles. This was gleaned from a study of the viscosity of mixtures of a hydrophobically modified cellulose polymer and surfactants in aqueous solution and the effect of concentration of mixed micelles. Specifically, it was found that a high viscosity is recoverable by increasing the surfactant aggregation number in the mixed micelles. The increase can be achieved either by adding a screening electrolyte or an oppositely charged surfactant to solutions with the hydrophobically modified polymer and an ionic surfactant.
