  • Patent number: 10292927
    Abstract: 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.

  • Publication number: 20090306254
    Abstract: Paint formulations that exhibit improved performance characteristics due to the presence of a combination of a cellulose ether (carboxymethylcellulose and/or hydroxyethylcellulose) and a network building polymer (gellan gum, carrageenan, etc., as examples) as a thickening system therein are provided. Such a combination permits long-term shelf stability of the paint formulation while simultaneously according effective flow, leveling, and other important properties to the final paint formulation. The combination of the cellulose ether and a network building polymer allows for a lower viscosity cellulosic compound to impart the desired rheological behavior therein while also permitting the other desirable characteristics noted above. Such paint compositions also exhibit improved atomization for spray applications with such a thickening system.
