ABSTRACT:
A composition and method for the improved deinking of groundwood newsprint is disclosed. The composition comprises an amount, effective for the intended purpose, of: 1) an anionic surfactant, e.g., the ammonium or sodium salts of a sulfated ethoxylate derived from a 12 to 14 carbon linear primary alcohol blend, and 2) a dispersant, e.g., naphthalene-formaldehyde condensates.
The method comprises administering a sufficient amount of this combined treatment to a sample of groundwood newsprint for which treatment is desired.
