ABSTRACT:
A water-soluble guar product is obtained by reacting guar gum with an aqueous phosphate solution and oxidizing the product in the presence of alkali. These two process stages can also be combined into a one-stage process. The desired product is also obtained by reaction of an already partially depolymerized guar gum with aqueous phosphate solution. The product whose viscosity in aqueous solution can be set very accurately is used as thickening agent, particularly in the paper industry.
