Patent ID: 7267743

Claim:
A process for the removal of ink from a fibrous cellulosic product, in which a wax-water emulsion is added to an alkaline aqueous mixture (at a temperature ranging from about 120 degrees F. to about 180 degrees F.) including fibrous cellulosic products containing ink, and removes the ink: the emulsion comprising about 10% to about 50%, based on the total weight of the emulsion of a hydrogenated vegetable wax, the wax being characterized by having an iodine value of less than about 10, and a melting point of between 120 to about 200 degrees F. (Mettler drop point); about 55% to about 75% by weight water, based on the total weight of the emulsion; about 20% to about 45% solids, based on the total weight of the emulsion; about 1% to about 25% by weight of a surface-active agent, based on the total weight of the emulsion; and about 0.02% to about 2.5% of an acid or base, based on the total weight of the emulsion; and wherein the wax is chosen from the group consisting of castor, soybean, palm, corn, cottonseed, rape, canola, sunflower, palm kernel, coconut, crambe, linseed and peanut.
