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.
