CMC DETERMINATION<br />
SURFACE TENSION RELATED TO HEADGROUP:<br />
CMC<br />
1. NON-IONIC <strong>DETERGENTS</strong> REDUCE<br />
SURFACE TENSION MORE EFFECTIVELY<br />
THAN CHARGED <strong>DETERGENTS</strong><br />
2. CHARGED <strong>DETERGENTS</strong> HAVE A LIMITED<br />
CAPACITY TO BIND TO THE AIR:WATER<br />
INTERFACE (CHARGE REPULSION)<br />
3. FOR LDAO <strong>AND</strong> OTHER IONIC <strong>DETERGENTS</strong><br />
CMC IS DEPENDENT ON IONIC STRENGTH<br />
(<strong>AND</strong> pH). ELECTROSTATIC INTERACTION<br />
OF COUNTERIONS.<br />
4. THE BULKIER THE HEADGROUP, THE LESS<br />
THEY REDUCE SURFACE TENSION.<br />
5. INCREASED CHAIN REDUCES CMC
