This poster provides an overview of our efforts toward designing biopolymer and toilet paper-based wet wipes that turn back into regular toilet paper when flushed. To date, we have examined two approaches to achieving this: one based on surfactant/biopolymer complexation and another based on ethanol-induced biopolymer gelation. Both strategies form solvated matrices of toilet paper interspersed with biopolymeric gels that turn back into regular toilet paper when placed in excess water. However, only one of these approaches (the ethanol-induced gelation) imparts the wipes with the target mechanical strength. Plans for future work and anticipated outcomes and conclusions are also briefly discussed.
