  2. Critical micelle concentration - Wikipedia

    en.wikipedia.org/wiki/Critical_micelle_concentration

    In colloidal and surface chemistry, the critical micelle concentration (CMC) is defined as the concentration of surfactants above which micelles form and all additional surfactants added to the system will form micelles. [1] The CMC is an important characteristic of a surfactant.

  3. Thermodynamics of micellization - Wikipedia

    en.wikipedia.org/wiki/Thermodynamics_of_micelliz...

    The critical micelle concentration (CMC) is the exact concentration of surfactants at which aggregates become thermodynamically soluble in an aqueous solution. Below the CMC there is not a high enough density of surfactant to spontaneously precipitate into a distinct phase. [7]

  4. Micellar solution - Wikipedia

    en.wikipedia.org/wiki/Micellar_solution

    Micellar solutions form when the concentration of amphiphile exceeds the critical micelle concentration (CMC) or critical aggregation concentration (CAC), which is when there are enough amphiphiles in the solution to clump together to form micells.

  5. Sodium dodecyl sulfate - Wikipedia

    en.wikipedia.org/wiki/Sodium_dodecyl_sulfate

    The critical micelle concentration (CMC) in water at 25 °C is 8.2 mM, [1] and the aggregation number at this concentration is usually considered to be about 62. [3] The micelle ionization fraction (α) is around 0.3 (or 30%). [4]

  6. Micellar liquid chromatography - Wikipedia

    en.wikipedia.org/wiki/Micellar_liquid_chromatography

    When the concentration of a surfactant in solution reaches its critical micelle concentration (CMC), it forms micelles which are aggregates of the monomers. The CMC is different for each surfactant, as is the number of monomers which make up the micelle, termed the aggregation number (AN). [5]

  7. Krafft temperature - Wikipedia

    en.wikipedia.org/wiki/Krafft_temperature

    It has been found that solubility at the Krafft point is nearly equal to critical micelle concentration (CMC). Below the Krafft temperature, the maximum solubility of the surfactant will be lower than the critical micelle concentration, meaning micelles will not form.

  8. Micelle - Wikipedia

    en.wikipedia.org/wiki/Micelle

    Polymeric micelles have a much lower critical micellar concentration (CMC) than soap (0.0001 to 0.001 mol/L) or surfactant micelles, but are nevertheless at equilibrium with isolated macromolecules called unimers. Therefore, micelle formation and stability are concentration-dependent. [3]

  9. Aggregation number - Wikipedia

    en.wikipedia.org/wiki/Aggregation_number

    In colloidal chemistry, an aggregation number is a description of the number of molecules present in a micelle once the critical micelle concentration (CMC) has been reached. In more detail, it has been defined as the average number of surfactant monomers in a spherical micelle. [1]
