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 solid polyol polyester and an emollient to improve the lubricity of the solid polyol polyester. The polyol polyester(s) and emollient remains at or near the skin surface, providing the desired BM cleaning or therapeutic benefits.
