Comparison of the influence of 1-propanol and of 2-propanol on the viscoelastic solutions of cetyltrimethylammonium bromide (CTAB) and sodium salicylate (NaSal)
It is known that mixtures of CTAB and NaSal form viscoelastic solutions. For a 100 mM CTAB solution and increasing NaSal concentration, the viscosity increases strongly at a concentration of 10 mM NaSal, reach...

Rheological behavior of wormlike micelles (WLMs) in alcohol/water mixed solvent: influence of alcohol chain length
The influence of replacing water with ethanol, propanol, and butanol in alcohol–water mixtures on the rheological properties of wormlike micelles (WLMs) consisting of sodium salicylate (NaSal) and cetyltrimeth...

The phase transition from L3 phase to vesicles and rheological properties of a nonionic surfactant mixture system
A sponge phase (L3 phase) was observed in aqueous solution of a nonionic surfactant polyethylene glycol ether of tridecyl alcohol with the average 3 of ethylene oxide (CH3(CH2)12(OCH2CH2)3OH, abbreviated as Tride...

Lamellar phase formation in catanionic mixtures of hydrogenated and fluorinated surfactants: a comparative study
The properties and phase behaviors of the catanionic mixtures consisting of tetradecyltrimetylammonium bromide (TTABr) and different anionic surfactants (i.e., sodium docanoate, C10HOONa; sodium laurate, C12HOONa...

Boosting the stability of protein emulsions by the synergistic use of proteins and clays
The preparation and the properties of high-pressure emulsions based on five different proteins are reported. As proteins, we used the well-studied bovine serum albumin (BSA), a biotechnical produced hydrophobi...

Influence of co-solvent on the rheological behavior of aqueous viscoelastic surfactant solutions
We have studied the influence of glycerol on the rheological behavior of viscoelastic surfactant solutions. The measurements were carried out on the system CTAB and NaSal. This system shows two viscosity maxim...
