Claim:
A disposable, single use personal care article, comprising: a) a water insoluble substrate consisting of a single layer having an active zone, a non-active zone adjacent to the active zone, and an interface therebetween; b) a coating composition with a melting point below 30 C, the coating composition containing at least one benefit agent selected from an active agent, a conditioning agent, an aesthetic agent and a mixture thereof for treating the skin or hair, the coating composition being releasably associated with the active zone; c) a carrier solvent with an effective diffusion rate within the water insoluble substrate, the carrier solvent being selected from water, a water miscible compound, an oil, an oil soluble compound, and a mixture thereof; wherein the coating composition is dissolved, dispersed, or emulsified in the carrier solvent; wherein the carrier solvent in the active or non-active zone is in a concentration range of about 5 to about 160 wt. % based on the substrate; and d) wherein the effective diffusion rate of the carrier solvent across the interface is substantially identical to the diffusion rate of the carrier solvent adjacent to the interface.
