Krafft temperature is defined as the temperature at which the solubility of a surfactant is equal to the surfactant's critical micelle concentration (CMC) at the same temperature.

Friedrich Krafft

It is named after German chemist Friedrich Krafft.
In colloidal chemistry, the Krafft temperature is named after him.

Cloud point

cloud
Visually the effect of going below the Krafft point is similar to that of going above the cloud point, with the solution becoming cloudy or opaque due to the surfactant molecules undergoing flocculation.

Increasing the length of the hydrocarbon chain increases the Krafft temperature because it improves Van der Waals forces.

Thermodynamics of micellization

The Krafft temperature determines the solubility of the surfactants which in turn is the temperature that CMC is achieved.

Micelle

Micelles form only when the concentration of surfactant is greater than the critical micelle concentration (CMC), and the temperature of the system is greater than the critical micelle temperature, or Krafft temperature.

Hydrogel encapsulation of quantum dots

At the appropriate Krafft temperature and critical micelle concentration these molecules will form individual tear-drop loops, where the hydrophobic ends are attracted to one another, to other molecules, and also to the similarly hydrophobic QDs.
