Wiping products, such as facial tissues, contain an interior temperature change composition and an exterior hydrophilic lotion composition that can provide a cooling sensation when contacted with the skin of a user. The temperature change composition, for instance, can contain one or more phase change agents that undergo a phase change at slightly elevated temperatures. The phase change agents, in one embodiment, can have a relatively high heat of fusion. When undergoing a phase change, the phase change agents absorb heat and thereby provide a cooling feeling to the skin of a user. The hydrophilic lotion composition may contain a carrier and a thermo-reversible gelling agent. The hydrophilic lotion composition maintains the temperature change composition within the tissue and helps to prevent skin irritation.
