ABSTRACT:
A system comprising a moisture containing cleansing article and a visual pH indicator changing color at a pH above 4.0. The system can comprise a buffer, having preferably a pKa above 5.5. The system can comprise a set of instructions for evaluating moisture containing cleansing articles. The pH buffer of the system can have a pKa value equal to or greater than the pH of the color change of the visual pH indicator. The pH of color change of the visual pH indicator can be equal to or greater than the pH of the lotion. The system can be used to evaluate the pH of moisture containing cleansing article lotions and to quantify the ability to neutralize alkalinity such as the alkalinity provided by residues of feces and urine over time on the skin of a baby.
