The influences of polymers and temperature on the foam properties of 3-dodecylalkoxyl-2-hydroxylpropyl trimethylammonium chloride

摘要

The foam performances of 3-dodecoxy-2-hydroxypropyl trimethylammonium chloride (C(12)TAC) have been determined in the existence of different relative amount of polymer. The experimental results show that the foaming ability of the mixture systems of the C(12)TAC/PEG and C(12)TAC/PVP is stronger than that of the surfactant solutions in the absence of polymer, and with the increase of relative amount of polymer both foaming efficiency and foam stability of the surfactant solutions are evidently enhanced. For the aqueous solution of the surfactant, effect of temperature on foaming properties has also been examined. The results show that both the foaming ability and stability of the foams of the surfactant solutions are highest (or strongest) at 30 degrees C.
