US 2012/0237683 A1 · Absorbent Article Having a Stable Skin Care Composition

Abstract

The present invention relates to an absorbent article having a stable skin care composition disposed on its skin-contacting surface. The skin care composition is readily transferable to the skin via normal contact, wearer motion, and/or body heat. Importantly, the skin care composition contains at least one skin care ingredient imparting visible skin benefits to the skin upon transfer to the skin and at least one rheological agent for stabilizing the composition such that agglomeration, stratification and/or settling of the composition are minimized. The present invention also relates to a process for making the absorbent articles having a stable skin care composition disposed thereon.
