  • Patent number: 8987438
    Abstract: A method for making a derivatized guar, comprising: (a) contacting derivatized guar splits, which have not been treated with a boron compound to crosslink the guar splits, with an aqueous wash medium comprising, based on 100 parts by weight of the aqueous wash medium: (i) from about 0.1 to about 30 parts by weight of a water soluble non-boron salt, or (ii) less than about 0.1 parts by weight water soluble salt, and (b) separating the washed derivatized guar splits from the aqueous wash medium, provided that the contacting of the derivatized guar splits with the aqueous wash medium comprising less than about 0.1 parts by weight water soluble salt is limited to a duration effective to maintain the water content of the washed derivatized guar splits at less than or equal to about 80 percent by weight.
