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.

Abstract
A disposable paper towel with an anti-microbial lotion and is provided with a chromatic transfer indicator which undergoes a delayed, visually perceptible color change at a predetermined time after the towel is wetted. An anti-microbial lotion on the towel increases water absorbency times (WAR) to further promote lotion transfer to the skin and increase lotion transfer effectiveness.

58. An anti-microbial paper towel comprising:
-
a) a cellulosic web; b) a waterless micro-emulsion which is substantially liquid at room temperature immobilized on the web in a semi-solid or solid state and selected and applied in amounts such that it imparts a water absorption rate delay of at least about 75% to the cellulosic web; c) wherein, the waterless mien-emulsion comprises an anti-microbial agent, a polar emollient, a non-polar emollient and a surfactant composition including a nonionic surfactant; and
wherein further the waterless micro-emulsion is capable of forming an aqueous micro-emulsion upon contact with water;d) a water soluble balancing agent disposed on the web at a plurality of discrete pH balancing agent locations; and e) 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 balancing agent in aqueous form; and wherein further 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 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.
