NOTE Effect of Surfactant Concentration and Film Area on the Stability of Films of Surfactant Solutions
The long relaxation time, t 2 , of micelles reaches a maximum at 200 m M SDS and is related to the micelle lifetime. It plays an important
The effect of surfactant concentration and film area on film role in various technological processes ( 10 ) . The emulsion droplet size stability was investigated in thin liquid films of sodium dodecyl for the SDS / hexadecane / water system reaches a maximum at a SDS sulfate ( SDS ) solutions. Film stability was evaluated at various concentration of 200 m M ( 11 ) . The maximum rate of solubilization concentrations of SDS solutions and various film areas. In this for benzene and Orange OT dye into SDS solutions also occurs at 200 study, a maximum film stability was observed for the SDS conm M SDS ( 12 ) . At the same concentration, the foamability is at a centration of 200 m M . Interestingly, this concentration also minimum and the bubble size is at its maximum ( 13, 14 ) . The wetting corresponds to the maximum micelle lifetime or long relaxation time of textile is also maximum at 200 m M SDS ( 15 ) . This paper time ( t 2 ) . The results also show that film stability decreases attempts to show that the structuring phenomenon for SDS micelles with increasing film area, and that the larger films appear to within the thin liquid films is also related to the micelle stability or be more sensitive to the micelle stability and structuring effect micelle relaxation time, t 2 ( 12 ) . In addition, the effect of film area on film stability of SDS solutions at various concentrations is investigated.
in the film than films with smaller surface areas.
