Abstract
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) 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.

A method of making a liquid detergent, comprising:
- providing a detersive surfactant package of one or more surfactants;
- providing at least one adjunct detergent ingredient,
- providing a protein component comprising a mixture of multiple intracellular proteins, at least a portion of the mixture including yeast polypeptides obtained from fermenting yeast cells and yeast heat shock proteins resulting from subjecting a mixture obtained from the yeast fermentation to stress, the 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, and
- combining the detersive surfactant, adjunct detergent ingredient, and protein component to obtain a liquid detergent composition.
