Abstract:
An enhanced washability ink composition has enhanced rinsability and/or washability from fabric, walls, or skin. The composition may comprise about 70 wt % to about 95 wt % water; about 5 wt % to about 35 wt % one or more sugars (e.g., dextrins); about 1 wt % to about 40 wt % one or more optional dye blockers; about 0.1 wt % to about 15 wt % one or more dyes; and one or more optional additives. The rinsable ink composition is usable in a variety of instruments, including markers or pens. A method for making the rinsable ink composition comprises dissolving one or more sugars (e.g., dextrins) in water to form a sugar solution; subsequently adding one or more dyes to the sugar solution to form a sugar-dye solution; and subsequently adding one or more optional dye blockers to the sugar-dye solution.
