Description

General description

Hexadecyltrimethylammonium p-toluenesulfonate is a catatonic surfactant capable of forming wormlike micelles.

Application

Hexadecyltrimethylammonium p-toluenesulfonate has been used in a study to develop a silica grafted polydentate copper (II) complex. It has also been used in a study to investigate the dispersibility and bundle defoliation of single-walled carbon nanotubes. [1]

The fluidity of Chinese hamster ovary cell and bull sperm membranes after cholesterol addition.

P H Purdy et al.

Cryobiology, 51(1), 102-112 (2005-07-05)

Cell plasma membrane fluidity is affected by membrane lipid and protein composition as well as temperature. Altering the cholesterol content of a membrane can change membrane fluidity at different temperatures and this may affect cell survival during cryopreservation. In these

New self-assembling systems based on bola-type pyrimidinic surfactants.

Lucia Zakharova et al.

Journal of colloid and interface science, 342(1), 119-127 (2009-11-07)

New amphiphilic pyrimidinic (AP) compounds with two ammonium head groups and different kinds of counterions, inorganic bromide anions (APB) and hydrophobic tosylate anions (APT) were synthesized. Self-organization in these systems has been studied by methods of tensiometry, conductometry, potentiometry and

Effects of electrolyte concentration and counterion valence on the microstructural flow regimes in dilute cetyltrimethylammonium tosylate micellar solutions.

N Tepale et al.

Journal of colloid and interface science, 363(2), 595-600 (2011-08-27)

The shear thickening behavior and the transition to shear thinning are examined in dilute cetyltrimethylammonium tosylate (CTAT) micellar solutions as a function of surfactant concentration and ionic strength using electrolytes with different counterion valence. Newtonian behavior at low shear rates
