Effect of counter ion concentration added with mixture of water and ethylene glycol on Krafft temperature of sodium dodecyl sulfate

<p>Surfactants are amphiphilic organic compounds having both hydrophobic and hydrophilic groups. Surfactants in solution form aggregates known as micelles. The minimum temperature at which surfactants forms micelles is known as Krafft temperature. The Krafft temperature of sodium dodecyl sulfate (SDS) was measured at various counter ion concentrations in two solvent systems, water and 10% ethylene glycol. The Krafft temperature of sodium dodecyl sulfate increased in both water and 10% ethylene glycol with increasing counter ion concentration. The Krafft temperature of sodium dodecyl sulfate in 10% ethylene glycol was higher than the Krafft temperature of sodium dodecyl sulfate in water, at the same counter ion concentration. Since the Krafft temperature of sodium dodecyl sulfate is higher in 10% ethylene glycol than in water at the same counter ion concentration, it has been concluded that the polarity of the solvent plays an important role in increasing the Krafft temperature of sodium dodecyl sulfate.</p>
