Abstract:
1. An antimicrobial paper towel with a chromatic transfer indicator comprising: a) a cellulosic web; b) a transferable lotion composition comprising an emollient and anti-microbial agent, the lotion composition being immobilized on the cellulosic web in a semi-solid or solid form and selected and applied in amounts such that it imparts a water absorption rate delay of at least about 25% to the cellulosic web, wherein the transferable lotion composition is selected from lotion compositions which are transferable upon contact with water or lotion compositions which are transferable upon application of heat; c) a water soluble pH balancing agent disposed on the web at a plurality of discrete pH balancing agent locations; and d) a pH-sensitive transfer indicator disposed on the web at a plurality of discrete indicator locations which are apart from the pH balancing agent locations, wherein the pH-sensitive transfer indicator is chromatically responsive to the pH balancing agent in aqueous form; wherein the pH balancing agent and the pH-sensitive transfer indicator are selected and applied to the web such that the pH-sensitive transfer indicator undergoes a gradual color change upon contact of the paper towel with water to indicate effective transfer of the lotion, wherein the initiation of said color change is determined by the wicking time of the pH balancing agent.
