There is debate about whether wipes are mekabel tumah (susceptible to ritual impurity, so that stains found on them could be halachically significant). Our site’s rabbinic supervisor follows the view that wipes are not mekabel tumah, as long as they are less than 50% cotton.
Disposable wipes that are not mekabel tumah are halachically comparable to toilet paper.
