Dispersion of hydrophilic gums to form non-swelling aqueous alcoholic mixtures

摘要

A process is presented for dispersing hydrophilic gums swiftly into formulations containing water wherein the lumping problem is avoided. The method of obtaining lump-free aqueous gum compositions comprises: (a) preparing a blend of water and an effective amount of water-miscible alcohol (I): <IMAGE> I wherein n and m are the same or different integers from 0 to 500, and when Y is hydrogen, (I) has a molecular weight of at least 200, and when Y is C1-C4 alkyl, (I) has a molecular weight of at least 32; (b) introducing into said aqueous alcohol blend a hydrophilic gum, resulting in a final weight ratio water:gum of about 20:1 to 1.3:1; (c) intimately mixing the resultant slurry; and (d) feeding the slurry into a water containing formulation.
