Quaternary ammonium caprylyl glycol disinfectant wipes
View Patent ↗A disinfectant wipe and disinfectant composition which exhibits exceptional antimicrobial activities as a result of the synergistic combination of a quaternary ammonium salts and 1,2-alkandiol is provided. The wipe is pre-impregnated with a disinfectant composition which comprises a quaternary ammonium salt, a 1,2-alkanediol with 5-10 carbon atoms, a glycol ether, a surfactant, a pH regulating agent, and water, and optionally alcohol. A method of preparation and a process for disinfecting a surface with the wipe composition are also provided.
1. A method of disinfecting a surface having mycobacterium thereon comprising:
applying an effective amount of a disinfecting composition onto a hard surface, using an applicator containing the disinfecting composition, said disinfecting composition comprising:
about 0.01 w/w % to about 1.0 w/w % of C 12 -C 18 alkyl dimethyl benzyl ammonium chloride, C 12 -C 14 alkyl dimethyl ethylbenzyl ammonium chloride, or mixtures thereof;
about 0.05 w/w % to about 6.0 w/w % of a 1,2-alkanediol;
about 0.5 w/w % to about 7.5 w/w % of dipropylene glycol mono-n-butyl ether, dipropylene glycol mono-n-propyl ether, or mixtures thereof;
about 0.01 w/w % to about 3.0 w/w % of a nonionic surfactant;
a pH regulating agent to make the pH of the composition between about 5.0 and about 11.5; and
water;
wherein said disinfecting composition disinfects the hard surface and kills the mycobacterium thereon, and
said disinfecting composition meets the United States Environmental Protection Agency's DIS/TSS-6 Efficacy Data Requirements for Supplemental Efficacy claims with respect to mycobacterium tuberculosis.
2. The method of claim 1 , wherein the applicator comprises a wipe.
3. The method of claim 2 , wherein the surface comprises a hospital area or hospital equipment.
4. The method of claim 2 , where the surface is exposed to the disinfecting composition for at least three minutes.
5. The method of disinfecting a surface of claim 1 , said method being effective to kill mycobacterium on the hard surface within 5 minutes of wiping the hard surface with the applicator containing the disinfecting composition.
6. The method of disinfecting a surface of claim 1 , said method being effective to kill mycobacterium on the hard surface within 3 minutes of wiping the hard surface with the applicator containing the disinfecting composition.
