Quaternary ammonium caprylyl glycol disinfectant wipes

Abstract

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 preimpregnated 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.

 (iv) about 0.01 w/w % to about 3.0 w/w % of an ethoxylated nonionic surfactant; 
 (v) alcohol in an amount of about 0 w/w % to about 15% w/w %; and 
 (vi) the balance being water; 
   wherein the substrate is impregnated with the composition at a loading level from about 1 .5 xow to about 10 xow.   
     
     
         2 . The antimicrobial wipe of  claim 1 , wherein the alcohol is present in the composition in an amount of about 0 w/w % to about 10% w/w %. 
     
     
         3 . The antimicrobial wipe of  claim 2 , wherein the alcohol is present in the composition in an amount of about 0 w/w % to about 5% w/w %. 
     
     
         4 . The antimicrobial wipe of  claim 3 , wherein the composition is free of alcohol. 
     
     
         5 . An antimicrobial wipe for use on hard surfaces comprising:
 (a) an absorbent nonwoven substrate; and   (b) a liquid composition comprising:
 (i) a quaternary ammonium salt at a range of about 0.01 w/w % to about 1 .0 w/w %; 
 (ii) a 1,2 alkandiol at a range of about 0.05 w/w % to about 6.0 w/w %; 
 (iii) a glycol ether at a range of about 0.5 w/w % to about 7.5 w/w %; 
 (iv) a surfactant at a range of about 0.01 w/w % to about 3.0 w/w %; 
 (v) alcohol in an amount of about 0 w/w % to about 15% w/w %; and 
 (vi) the balance being water; 
   wherein the substrate is pre-impregnated with the composition at a loading level from about 1 .5 xow to about 10 xow.   
     
     
         6 . The antimicrobial wipe of  claim 5 , wherein the alcohol is present in the composition in an amount of about 0 w/w % to about 10% w/w %. 
     
     
         7 . The antimicrobial wipe of  claim 6 , wherein the alcohol is present in the composition in an amount of about 0 w/w % to about 5% w/w %. 
     
     
         8 . The antimicrobial wipe of  claim 7 , wherein the composition is free of alcohol. 
     
     
         9 . A disinfecting composition, comprising:
 (i) a quaternary ammonium salt at a range of about 0.01 w/w % to about 1.0 w/w % of the composition;   (ii) a 1,2-alkanediol at a range of about 0.05 w/w % to about 6.0 w/w % of the composition;   (iii) a glycol ether at a range of about 0.5 w/w % to about 7.5 w/w % of the composition;   (iv) a surfactant at a range of about 0.01 w/w % to about 3.0 w/w % of the composition;   (v) alcohol in an amount of about 0 w/w % to about 15% w/w %; and   (vi) water.   
     
     
         10 . The disinfecting composition of  claim 9 , wherein the alcohol is present in the disinfecting composition in an amount of about 0 w/w % to about 10% w/w %. 
     
     
         11 . The disinfecting composition of  claim 10 , wherein the alcohol is present in the disinfecting composition in an amount of about 0 w/w % to about 5% w/w %. 
     
     
         12 . The disinfecting composition of  claim 11 , wherein the composition is free of alcohol. 
     
     
         13 . A method of disinfecting a surface comprising the step of:
 applying an effective amount of a disinfecting composition onto a 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, and 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, and 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;   about 0 w/w % to about 15% w/w % of alcohol; and   water.
