ABSTRACT:
The present invention uses hydrophobically modified polyaminamide with standard wet strength agent to produce a softer and more absorbent paper material. The hydrophobically modified polyaminamide is substantive to cellulosic fibers, thus is able to carry polyethylene glycol esters or ethers, a non-substantive material to cellulosic fiber as stable complexes, into the paper product.
