Abstract

A process for making surfactant granules involving: (a) providing a surfactant component selected from the group consisting of a surface-active protein, a surface-active protein derivative, and mixtures thereof; (b) providing a disintegrator component; (c) combining the surfactant component and the disintegrator component to form a surfactant mixture; and (d) granulating and compacting the surfactant mixture to form the surfactant granules.
