Abstract:
1. A feminine care absorbent article comprising; a generally liquid-impermeable layer; a liquid-permeable layer; an absorbent core positioned between the generally liquid-impermeable layer and the liquid-permeable layer; an antimicrobial composition that is uniformly disposed on the liquid-permeable layer, wherein the antimicrobial composition comprises an acidic compound, wherein the acidic compound is a weak organic carboxylic acid; and a sensor that comprises a pH-sensitive composition, wherein the sensor is integrated into the article and positioned such that the pH-sensitive composition is in fluid communication with a bodily fluid from a user of the feminine care absorbent article, wherein the pH-sensitive composition includes a chromogen that undergoes a visible color change upon contact with the bodily fluid, the visible color change occurring at a pH level of from 3 to 9 so that the pH-sensitive composition exhibits a first color at pH levels of less than 3 and a second color at pH levels of 9 or more, and wherein the pH-sensitive composition further includes an organic hydrophilic binder present in an amount ranging from 40 wt.% to 85 wt.% based on a dry weight of the pH-sensitive composition, wherein the presence of the second color signals to the user whether the antimicrobial composition is effective in inhibiting microorganism growth or is beginning to lose or has lost its efficacy.
