Microfibrous cellulose (MFC) broths are provided having improved performance as compared to wet cake microfibrous cellulose (MFC) and powdered microfibrous cellulose (MFC). In embodiments, compositions having an effective amount of an MFC broth and an effective amount of a surfactant have an improved yield value as compared to a composition having a surfactant and a wet cake MFC, a powdered MFC, or a combination thereof at the same concentration as the MFC broth. Also, methods are provided for improving the yield value of surfactant compositions by adding an effective amount of a microfibrous cellulose broth to an effective amount of surfactant to provide a surfactant composition having a yield value that is higher than a composition having the surfactant and a wet cake MFC, a powdered MFC, or a combination thereof at the same concentration as the microfibrous cellulose broth.

Microfibrous cellulose composition comprising fermentation media and surfactant

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 5% to about 50% (w/w active surfactant), and a particulate. Also provided herein are methods for preparing surfactant systems including microfibrous cellulose.

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.

Cationic surfactant systems, using microfibrous cellulose to suspend particulates therein, are described. Methods of making these systems are also described.

Rheologically modified compositions, and rheologically modified fluid compositions prepared therefrom, containing reticulated bacterial cellulose in a polyol base fluid, are disclosed. The amount of reticulated bacterial cellulose present in the composition is an amount effective to viscosify the polyol base fluid.

Reticulated bacterial cellulose as a rheological modifier for polyol

This invention is directed to a rheologically modified composition containing scleroglucan in an polyol base fluid. The amount of scleroglucan present in the composition is an effective amount to viscosity an polyol base fluid to the point of substantially reducing convection flow in the composition. The composition may be used as an effective thermal insulation material. Applications for this type of insulating material include, among others, use as a de-icing fluid and use as a pipeline insulator. The rheologically modified insulation composition of this invention may be particularly suitable for maintaining high oil temperature during conveyance within a pipe located in a relatively low temperature environment such as sea water.

Scleroglucan as a rheological modifier for thermal insulation fluids

A liquid carrier fluid that is used as a carrier system to suspend and deliver water soluble polymers which act to adjust the rheological properties of the aqueous systems to which they are added.
