Micelles and CMC Flashcards
1
Q
Define micelles
A
Colloid sized cluster of molecules
=> formed only above Krafft temperature and Critical micelle concentration (CMC)
=> non ionic surfactant- clumps of 1000+
=> flattened spheres common close to CMC
=> Micelle phase is a mixture of surfactant and water
2
Q
What can affect CMC?
A
Chemical structure, temperature,
presence of other molecules
3
Q
Describe when C< CMC
A
Single monomers float in bulk phase, tails in air heads in water
