Micelle Temperature Range (MTR or Krafft Point)

  • Yoshikiyo Moroi

Abstract

Detergent action, colloid formation, and surface activity are different manifestations of the same characteristics of surfactant solutions. Detergency is the most important and conventional function of soaps, and is closely connected with their solubility. Because typical surfactant molecules (including soaps) have both a hydrophilic group and a bulk hydrophobic group, their aqueous solubility is not expected to be high. That is true below a certain narrow temperature range called the Krafft point. Above this range, the solubility of the surfactant increases very steeply because surfactant aggregation is taking place.
