Abstract
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.
Claims21
An aqueous composition comprising a high surfactant system consisting essentially of water, a microfibrous cellulose present in the aqueous composition at a concentration from about 0.05% to about 0.155% (w/w), a surfactant present in the aqueous composition at a concentration from about 51% to about 99% (w/w active surfactant), and a suspended particulate, wherein the aqueous composition is clear.
A surfactant system comprising a microfibrous cellulose, a surfactant, and a suspended particulate, wherein the microfibrous cellulose is present at a concentration of about 0.125% and the surfactant is present at a concentration of about 99% (w/w active surfactant).
Method of preparing a surfactant system comprising:
- combining a microfibrous cellulose with water and mixing with high shear,
- adding a surfactant and then mixing, and
- adding particulates followed by mixing,
- wherein the microfibrous cellulose is present at a concentration from about 0.05% to about 0.15% (w/w), the surfactant is present at a concentration from about 51% to about 99% (w/w active surfactant), and the resulting system is clear and the particulates are suspended therein.
Method of preparing a surfactant system comprising a microfibrous cellulose, a surfactant, and particulates comprising:
- combining a microfibrous cellulose with water and mixing,
- adding a surfactant and then mixing, and
