Effect of Solvent System on Critical Micelle Concentration Using Viscosity Equations for Anionic Surfactants at Various Temperatures

Yogyta Singh | Pratima Jain ^[2]

Abstract: The critical micelle concentration (CMC) of Potassium Stearate (PS), Sodium Oleate (SO) and Sodium Dodecyl Sulphate (SDS) in alcohol- water solvent system (0 %, 50 %, 80 %, 90 %, and 100 %) was driven from the density and viscosity measurements. The concentrations of PS, SO and SDS in different solvent systems used for the density and viscosity measurements were kept between 0.010 to 0.065g mol L-1and measurements were taken at different temperatures. Experimental density values were seen to get decreased with the increase of the temperature. The viscosities are also represented in terms of Einstein, Vand, Moulik and Jones-Dole equations. We found that the viscosity of the salts in various solvent mixture decrease with increase in temperatures and all the values show positive trends.
