Abstract
A diaper containing a liquid pervious topsheet coated with a lotion composition is disclosed. The lotion composition reduces the adherence of BM to the skin of the wearer, thereby improving the ease of BM clean up, and improves skin softness. The lotion composition comprises a liquid polyol polyester and an immobilizing agent such as a fatty alcohol or paraffin wax to immobilize the liquid polyol polyester on the surface of the diaper topsheet. The polyol polyester(s) remains at or near the skin surface, providing the desired BM cleaning and/or therapeutic benefits.
