Patent ID: 8133825

Claim:
A wet wipe comprising a nonwoven material; wherein the nonwoven material comprises a binder composition; wherein the binder composition comprises a cationic ion-sensitive emulsion polymer; wherein the cationic ion-sensitive emulsion polymer comprises the emulsion polymerization product of at least one hydrophobic monomer which has been stabilized by a solution-polymerization-derived cationic ion-sensitive polymer stabilizer; wherein the cationic ion-sensitive emulsion polymer comprises between 1 wt % and 55 wt % of the solution-polymerization-derived cationic ion-sensitive polymer stabilizer; wherein the nonwoven material comprises a fibrous material; and wherein the solution-polymerization-derived cationic ion-sensitive polymer stabilizer is the polymerization product of methyl acrylate and [2 (acryloxy)ethyl]trimethyl ammonium chloride.
