Abstract
Wiping products, such as facial tissues, contain a temperature change composition that can provide a cooling sensation when contacted with the skin of a user. The temperature change composition includes a phase change material and a non-interfering molecular scaffold. The phase change materials, in one embodiment, can have a relatively high heat of fusion. When undergoing a phase change, the temperature change composition absorbs heat and thereby provides a cooling feeling or cooling sensation to the skin of a user.
