Patent number: 9011643Abstract: Disclosed herein are cellulase compositions useful as papermaking performance additives for improving paper dry strength of a paper product and reducing refining energy in papermaking processes, and improving paper production. These cellulase compositions are formulated using cellulase, papermaking contaminant control polymers, protein stabilizers and cellulase enhancers. These cellulase compositions measure higher in endo-cellulase activity with better stability than conventional cellulase, and have shown differentiating performance in improving paper dry strength properties versus cellulase alone.Type: GrantFiled: October 8, 2013Date of Patent: April 21, 2015Assignee: Solenis Technologies L.P.Inventors: Qu-Ming Gu, Frank J.
