A wet wipe with a substrate having cellulosic fibers and a lotion is provided. The lotion may have between about 96.0% and about 99.5%, by weight of the lotion, of water. The lotion may have a preservative system having benzoic acid and/or a salt thereof, succinic acid and/or a salt thereof, and phytic acid and/or a salt thereof. The lotion may also have a surfactant, pH buffering system, and a pH of about 3.5 to about 5.

Described are sensors and methods of detecting hydrogen gas. The sensor includes a polymer matrix and a dye molecule in an amount sufficient such that exposure of the polymer matrix to hydrogen gas causes a change in a spectroscopic property of the dye molecule wherein the spectroscopic property includes at least one of color, absorbance, or luminescence. The polymer matrix may further include a catalyst, such as a transition metal, sulfonated Wilkinson's catalyst, colloidal Pt, sulfonated iridium cyclooctadiene triphenylphosphine, sulfonated rhodium cyclooctadiene triphenylphosphine, sulfonated ruthenium triphenylphosphine, or combinations thereof. Embodiments of the sensor may further include a gas permeable, water impermeable membrane, an outer covering, or combinations thereof.
