Claim Text:
1. A method for making a debonded paper sheet, comprising: preparing a volatile debonder formulation comprising at least one volatile debonder and water, applying the volatile debonder formulation to a paper precursor to form a debonded paper precursor, wherein the volatile debonder formulation is applied to the paper precursor in an amount effective to reduce hydrogen bonding of the cellulose fibers of the paper precursor, and processing the debonded paper precursor through a papermaking machine, wherein the processing comprises a drying step, and wherein the volatile debonder evaporates from the debonded paper precursor during the drying step, without leaving debonder residua when detected using thermogravimetric mass spectrometry, thereby forming the debonded paper sheet, wherein the debonded paper sheet does not comprise a debonder that includes both a quaternary ammonium salt and a hydrophobic chain; and wherein the volatile debonder is a glycol ether.
