Abstract
The instant invention is directed to a process for enhancing the efficacy of alcohol-based skin antiseptics comprising adding at least one alcohol-soluble viscosifying agent to an alcohol-based disinfectant, thereby lowering its alcohol evaporation rate and markedly increasing the exposure time that disinfecting concentrations of alcohol are present on skin. The improved alcohol-based antiseptics thus obtained are also claimed.
Claims2
A method for enhancing the efficacy of an alcohol-based skin disinfectant containing about 30 to 90 percent, based on total composition weight, of at least one alcohol selected from the group consisting of n-propyl alcohol, isopropyl alcohol and ethyl alcohol comprising adding about 0.25 to about 5 percent, based on total composition weight, of at least one alcohol-soluble hydroxypropyl cellulose polymer viscosifying agent to said alcohol-based skin disinfectant, thereby increasing its antimicrobial effectiveness against Serratia marcescens, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa or Candida albicans.
