Percent of total liquid released from towelette after wiping and bactericidal efficacy against S. aureus and P. aeruginosa (expressed as log10 reduction values) over varying surface areas wiped for each disinfectant towelette product tested. To determine the factors significantly impacting bacteria reduction, a generalized linear mixed model was developed with least squares means comparison and Tukey adjustment detecting significant differences in bacteria log10 reduction due to area, disinfectant, strain, and their interaction (n = 399). Data were fitted into a generalized linear mixed model with Proc Glimmix to determine the significant factors impacting the percent of liquid expended (n = 800). Least square means comparison with Tukey-Kramer adjustment was used to determine significant differences in the percent of liquid deposited onto a surface across eight areas, ten disinfectant products (with PBS wetted wipes as the control), and combinations of their interaction. a Percent of liquid released and efficacy over varying surface areas for a 0.55% sodium hypochlorite product; b Percent of liquid released and efficacy over varying surface areas for a 0.5% quat product + 55% alcohol; c Percent of liquid released and efficacy over varying surface areas for PBS-wetted control towelette; d Percent of liquid released and efficacy over varying surface areas for a 1.312% sodium hypochlorite product; e Percent of liquid released and efficacy over varying surface areas for a 1.4% hydrogen peroxide product; f Percent of liquid released and efficacy over varying surface areas for a 0.5% hydrogen peroxide product; g Percent of liquid released and efficacy over varying surface areas for a 0.21% quat product; h Percent of liquid released and efficacy over varying surface areas for a 0.28% quat product; i Percent of liquid released and efficacy over varying surface areas for a 0.76% quat + 22.5% alcohol product; j Percent of liquid released and efficacy over varying surface areas for a 0.308% quat + 21% alcohol product; k Percent of liquid remaining and efficacy over varying surface areas for 0.61% quat + 56% alcohol product
