Title:
水溶性、低い置換度のヒドロキシエチルセルロース、それらの誘導体、それらの製造方法および使用
Document Type and Number:
Japanese Patent JP5739081
Kind Code:
B2
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.
