Surface and Antimicrobial Activity of Sulfobetaines

Sulfobetaines belong to the group of zwitterionic surfactants. They are electroneutral salts, which have in the same molecule, two ionic centers with different charge. Due to the specific structure they exhibit excellent properties such as good solubility in water and detergency. In this paper we present surface properties and adsorption parameters of sulfobetaines in water/air systems. From the adsorption isotherms the CMC value, the surface tension and surface pressure at the CMC as well as the efficiency of adsorption were determined. Physicochemical analyses of the data allowed for the further description of adsorption process. Results showed that sulfobetaines exhibit good surface properties especially low CMC and p20 values. Additionally the antimicrobial activity of sulfobetaines solutions against gram-positive and gram-negative bacteria were tested by the well-diffusion method. MIC values and growth kinetics were determined by microdilution method. Antimicrobial assays demonstrated that sulfobetaines can be good antibacterial agents, but the activity of surfactants strongly depends on alkyl chain length.

Synthesis, characterization and surface properties of series sulfobetaine surfactants

A series of surface active sulfo-propane betaines and sulfo-butane betaines were synthesized with high yields by the reaction of an appropriate N,N-dimethyl alkylamine with an excess of 1,3-propane sultone and 1,4-butane sultone. The structures were characterized by 1H-NMR spectroscopy and elemental analysis. The micellar properties of these compounds were determined by surface tension methods. Surface tension measurements also provide information about the dependence of the surface tension at the CMC (γcmc), pC20 (negative logarithm of the surfactant molar concentration C20 required to reduce the surface tension by 20 mN/m), the surface excess (Γmax) at air/solution interface, the minimum area per surfactant molecule at the air solution interface (A).
