Surfactant systems are provided using microfibrous cellulose to suspend particulates. In one embodiment the surfactant system includes a microfibrous cellulose at a concentration from about 0.05% to about 1.0% (w/w), a surfactant at a concentration of about 51% to about 99% (w/w active surfactant), and a suspended particulate. Also provided herein are methods for preparing surfactant systems including microfibrous cellulose.
