  • Water-soluble, low substitution hydroxyethylcellulose, derivatives thereof, process of making, and uses thereof
    Publication number: 20060199742
    Abstract: This invention relates to water-soluble hydroxyethylcelluloses (HECs) and derivatives thereof having a hydroxyethyl molar substitution (HE-MS) from about 0.7 to 1.3. These HECs are more efficient in thickening aqueous systems than prior art HEC products and show unique rheology in low water activity systems. These HECs can be distinguished from prior art and commercial HEC products by having an unsubstituted anhydroglucose trimer ratio (U3R) less than 0.21 and a water solubility greater than 90 wt %. This invention also relates to a unique continuous caustic reduction hydroxyethylation process for making the water-soluble, lowly substituted HECs and uses thereof in functional systems.
