Claim:
1. An absorbent article comprising: a moisture-impervious outer layer; an inner layer substantially co-extensive with the outer layer, the inner layer being treated with at least one antimicrobial booster such that the at least one antimicrobial booster is mixed throughout the material of the inner layer prior to forming the inner layer, the at least one antimicrobial booster including two or more 1,2-alkanediols; and an absorbent layer interposed between the outer layer and the inner layer, the absorbent layer being treated with at least one antimicrobial agent such that a wearer is insulated from the at least one antimicrobial agent, the at least one antimicrobial agent comprising polyhexamethylene biguanide, wherein the at least one antimicrobial booster is configured to synergistically combine with the at least one antimicrobial agent when moisture is introduced into the article in use to (i) achieve a microbe kill rate that is greater than the microbe kill rate achieved by the antimicrobial booster or the antimicrobial agent individually, and (ii) minimize the irritating effects of the antimicrobial agent on a user when the absorbent article is in use.
