The surface tensions of these two states are fitted linearly, respectively, and the intersection point is approximately the critical micelle concentration (cmc) of the synthetic product [33].

The critical micelle concentration (CMC) values of the surfactants 2c and 2d were found to be 7.63 x [10.sup.-4] and 1.23 x [10.sup.-4] mol/L, and the corresponding surface tension ([[gamma].sub.CMC]) values were 31.83 and 31.69 mN/m, respectively.
In the present study, the compound 3-(benzoxazol-2-yl)-7 -(N,N-diethylamino)chromen-2-one (BDC), Figure 1, was used as extrinsic fluorescence probe to determine, by steady-state fluorescence, the Critical Micelle Concentration of Triton X-100 (TX-100) in phosphate-buffered saline (PBS buffer, pH 7.4) aqueous medium.
Gemini surfactants has lower critical micelle concentration (CMC), a relevant foaming capacity and lower Krafft point, so as to display more potent abilities to form micelles reduce the interface tension compared with their corresponding conventional single-chain surfactant counterparts [7-11].
Present investigation is based on the critical micelle concentration (CMC) point and either any type of surfactants only or mixtures with starches, same results are found due to saturation and maximum interaction occurred in this points.
Above the critical micelle concentration (CMC) increase of surfactant concentration is associated with constant concentration of free amphiphilic molecules (ions), whereas level of micellar phase (association colloid) is elevated.
Only PSS appears to irreversibly adsorb onto metal oxides surface because of multisite adsorption and kinetic limitations while the adsorption of surfactant is almost completely prevented at concentration higher than critical micelle concentration (CMC).
Above the critical micelle concentration (CMC), the surfactants aggregate into micelles or differently shaped assemblies.
Above the cloud point temperature, aqueous solution of a nonionic surfactant separates into two phases, namely, a surfactant rich phase, which has small volume compared to the solution and is called coacervate phase, and the other is dilute bulk aqueous phase containing surfactant concentration slightly above the critical micelle concentration (CMC) [6].
When SLs are solved in water, they lower the surface tension from 72.8 mN/m down to 40 to 30 mN/m, with a critical micelle concentration of 40 to 100 mg/L.
The critical micelle concentration (CMC) of SDS in water was found to correspond to 0.2 % mass fraction which is equivalent to a molarity of 0.008 mol/L.
