The microfibrillated cellulose, a form of cellulose having a very large available surface area per unit of weight, acts to confer, among other benefits, greater stability on the suspension. The suspensions are useful in a variety of end use products including foods, cosmetics, pharmaceuticals, paints and drilling muds. | |
