Abstract
A process for making and using a ground product that includes the steps of: reacting a guar split with propylene oxide at a reaction temperature in a range of 120° F. to 180° F. to form a guar derivative; and treating the guar derivative with at least one of washing and drying to form a resultant treated derivative. The process includes transferring the resultant treated derivative to a co-grinder operably associated with a heated vacuum system; and co-grinding the resultant treated derivative with a powdered carboxylic acid to form a ground product.
