(a) one or more layers of water-insoluble substrate; and (b) a safe and effective amount of antimicrobial cleansing composition, comprising by weight of the antimicrobial composition:
(i) from about 0.001% to about 5% of an antimicrobial agent; (ii) from about 0.01% to about 20% of an amphoteric surfactant; (iii) from about 0.1% to about 20% of 2-pyrrolidone-5 carboxylic acid; and (iv) from about 3% to about 99% of an aqueous component, wherein the composition has a pH in the range of about 2.0 to about 5.5.
- 14. A method for cleansing and disinfecting skin comprising the applying a safe and effective amount of the composition of claim 1 on mammalian skin.
- 15. A method for cleansing and disinfecting skin comprising the applying the antimicrobial cleansing wipe of claim 13 on mammalian skin.
