    Abstract: Methods of treating hydrocarbon fluids to reduce the apparent viscosity of hydrocarbon fluids encountered in petroleum operations and reducing deposits within a well annulus or a pipeline are disclosed. The method comprises contacting such fluids with a hydrophobically modified polysaccharide to create water external emulsions. The disclosed hydrophobically modified polysaccharides have been demonstrated to reduce interfacial tension to below 65 mN/m and thereby improve the transportability of inherently viscous hydrocarbon fluids, such as heavy crude oils.

    Abstract: A chemical softening composition includes a amide-substituted quaternary imidazolinium salt, a nonionic surfactant, and a polyhydroxy compound for use in treating cellulosic materials including papers, textiles and fabrics. The chemical softening composition can be applied to papermaking fibers during a papermaking process to provide a softened paper web and product possessed of sufficient tensile strength for its regular employment. A chemical softening composition according to the invention can also be applied to fabric to soften the fabric, provide easier handling of the fabric, and also reduce the tendency of the fabric to generate and store static electricity.
