Relationship between Micellar Lifetime and Foamability of Sodium Dodecyl Sulfate and Sodium Dodecyl Sulfate/ 1-Hexanol Mixtures
The interface between air and surfactant solution expands rapidly during the foam generation process. Surfactant molecules in the solution should adsorb onto the newly created surface to stabilize foam. As surfactant monomers adsorb on the surface, micelles disintegrate to provide additional monomers to adsorb on the expanding interface of foam. If micelles are very stable, they cannot rapidly ...
متن کاملMicellization of sodium dodecyl sulfate and polyoxyethylene dodecyl ethers in solution
The effect of polyoxyethylene type nonionic surfactants (C12En n=3, 4, 5, 6, 7 and 8) on the aqueous solution of sodium dodecyl sulfate (SDS) in absence and presence of NaCl was examined using small-angle neutron scattering (SANS), dynamic light scattering (DLS), and viscosity measurements. Upon addition of C12En, micellar size of SDS was found to increase significantly, and such micellar elong...
متن کاملEffect of Micellar Lifetime on the Wetting Time of Cotton in Sodium Dodecyl Sulfate Solutions
Textile wetting involves the displacement of air by surfactant solutions in the fiber matrix. The kinetics of surfactant adsorption is more important than the equilibrium properties of surfactant solutions for the textile wetting process because equilibrium conditions are rarely attained during the time allowed for wetting in textile processing.' Fowkes observed that the log of the wetting time...
متن کاملEffect of Antifoaming Agents on the Micellar Stability and Foamability of Sodium Dodecyl Sulfate Solutions
The effect of antifoaming agents on the foamability of sodium dodecyl sulfate (SDS) solutions was investigated and correlated with their effect on the micellar relaxation time τ2. The slow micellar relaxation time τ2 of SDS micelles, which is directly related to micellar stability, was determined by the pressure-jump method in the presence of the antifoaming agents 2-ethylhexanol (EH), tributyl...
متن کاملThe effect of cosurfactants on sodium dodecyl sulfate micellar structures at a graphite surface
Sodium dodecyl sulfate (SDS) self assembles at hydrophobic graphite surfaces forming linear parallel hemicylinders with approximately 5 nm spacing between adjacent hemicylinders. In this paper, we report the effect of cosurfactants on the SDS surface micelle structures. It is known from the literature that cosurfactants influence the relaxation times of bulk phase micelles. Specifically, the re...
