[0168] Comparative Examples 1-3 and Examples 1a-14

[0169] Pad samples were prepared and tested for artificial urine odor as described above. For these examples, the antimicrobial composition was manually applied to a nonwoven substrate. The amount of SA ranged from 4% to 20% by weight, and the PEG3350:CA carrier ratio was 2:1 or 1:1. Several samples of unmodified pads were also tested as controls. The antimicrobial coating compositions and odor test results are shown in Table 1.

[0173] Pantiliner samples were prepared and tested for artificial urine odor as in Examples 3a-3e above, except that the antimicrobial composition was applied to the nonwoven substrate using the spray application method described above. A sample of the unmodified pad was also tested as a control. The results are provided in Table 2.

[0177] Antimicrobial coatings were prepared using organic acids other than SA. Samples were prepared and subjected to the artificial urine odor test as described above. The amount of organic acid was 8 wt% or 20 wt%, and the PEG3350:CA carrier ratio was 2:1 or 1:1. The antimicrobial coating formulations and odor test results are shown in Table 3.
