Abstract
This invention relates to a blend of cellulase-free xanthan gum with a number of cellulosics, including carboxymethyl cellulose, hydroxyethyl cellulose and hydroxypropylmethyl cellulose. At 1:1 weight ratio, these blends show surprising viscosities when tested in aqueous solutions of 1%, 0.5%, 0.25% and 0.1% total gum concentration. The blends have utility in any application where cellulosics are used as thickeners, such as industrial or food applications, e.g., toothpaste, or drink mix formulations.
