REDUCTION OF SURFACE TENSION, INTERFACIAL TENSION, AND CRITICAL MI CELLE CONCENTRATION USING A PROTEIN-BASED SURF ACT ANT SYNERGIST
Surfactant-containing compositions are described which include a protein component that has the effect of improving the surface-active properties of the surfactants contained in the compositions. The surfactant-containing compositions having the protein component demonstrate significantly lower critical micelle concentrations (CMC), reduced surface tensions, and reduced interfacial tensions than do comparable compositions having no protein component. In addition, the surfactant-containing compositions having the protein component has the effect of converting greasy waste contaminants to surface active materials.
1 . A surfactant composition comprising:
a surfactant package of one or more surfactants, at least one of said one or more surfactants comprising a dioctyl ester of sodium sulfosuccinic acid, and
a protein component having a concentration sufficient to substantially increase the surface activity of the one or more surfactants relative to the surface activity of the one or more surfactants in the absence of the protein component.
