Abstract: A cosmetic wipe that contains a first nonwoven layer having first and second opposing surfaces is provided. The first nonwoven layer contains fibers formed from a polymer composition and is generally opaque in nature. A second nonwoven layer is laminated to the first surface of the first nonwoven layer. The second nonwoven layer contains a colorant that imparts a certain color to the second layer.

Thus, at least a portion of the first layer becomes translucent or transparent so that the color of the second layer becomes visible to a user. This provides a variety of benefits, including the ability for a user to evaluate if or how much sebum was removed from the skin so that makeup, etc.
