Moisturizing liquid composition with cationic biocide

Abstract

A liquid cleaning composition including: at least 80 wt. % liquid solvent; a cationic quaternary amine biocide; and a non-cationic moisturizing agent, wherein the composition reduces bacteria by at least 2.0 log 10 when assessed using ASTM E1174 and reduces drying of the stratum corneum compared with a water control between 30 and 180 minutes after application.

         1 . A liquid cleaning composition, the composition comprising:
 at least 80 wt. % liquid solvent;   a cationic quaternary amine biocide; and   a non-cationic moisturizing agent,   wherein the composition reduces bacteria by at least 2.0 log 10 when assessed using ASTM E1174 and reduces drying of the stratum corneum compared with a water control between 30 and 180 minutes after application.   
     
     
         2 . The composition of  claim 1 , further comprising an ionic zinc compound, wherein the zinc compound comprises 0.01 wt. % to 0.5 wt. 5 of the composition. 
     
     
         3 . The composition of  claim 1 , further comprising a second cationic quaternary amine biocide, wherein the second cationic quaternary amine biocide comprises 0.5 wt. % to 5 wt. % of the composition. 
     
     
         4 . The composition of  claim 1 , wherein the composition is substantially free of low molecular weight mono-alcohols.

         6 . The composition of  claim 1 , wherein the reduction in drying of the stratum corneum is assessed with a lower leg controlled application test (LCAT). 
     
     
         7 . The composition of  claim 1 , wherein the cationic quaternary amine biocide is benzalkonium chloride (BAC). 
     
     
         8 . The composition of  claim 1 , further comprising two non-ionic surfactants. 
     
     
         9 . The composition of  claim 1 , further comprising 0.002 wt. % to 5 wt. % of an unmodified polyglycol of 6 to 12 repeat units. 
     
     
         10 . A liquid cleaning composition, the composition comprising:
 at least 80 wt. % water;   a first cationic quaternary amine biocide;   a second cationic quaternary amine biocide; and   an unmodified polyglycol,   wherein the composition reduces bacteria by at least 2.0 log 10 when assessed using ASTM E1174 and reduces drying of the stratum corneum compared with a water control between 30 and 180 minutes after application as assessed with a lower leg controlled application test (LCAT).   
     
     
         11 . The composition of  claim 10 , further comprising an ionic zinc compound, wherein the zinc compound comprises 0.01 wt. % to 0.5 wt. % of the composition. 
     
     
         12 . The composition of  claim 10 , wherein the first cationic quaternary amine biocide is benzalkonium chloride (BAC) and the second cationic quaternary amine biocide is a cetrimonium salt. 
     
     
         13 . The composition of  claim 10 , further comprising a non-ionic surfactant, wherein the non-ionic surfactant comprises 0.03 wt. % to 6 wt. % of the composition. 
     
     
         14 . A liquid cleaning composition, the composition comprising:
 at least 80 wt. % water;   0.06 wt. % to 1 wt. % of a cationic biocide;   0.7 wt. % to 3 wt. % glycerin;   0.01 wt. % to 5 wt. % of a polycarboxylic acid and/or salt thereof; and   0.01 wt. % to 1 wt. % myristamidopropylamine oxide.   
     
     
         15 . The composition of  claim 14 , wherein the cationic biocide comprises benzethoium chloride (BZC). 
     
     
         16 . The composition of  claim 14 , wherein the polycarboxyllic acid and/or salt thereof is comprises three carboxyl groups per molecule. 
     
     
         17 . The composition of  claim 14 , wherein the polycarboxylic acid and/or salt comprises an acid selected from the group consisting of: citric acid, a citrate salt, ethylenediaminetetraacetic acid (EDTA), an EDTA salt, oxalic acid, an oxalate salt, and mixtures thereof. 
     
     
         18 . The composition of  claim 14 , wherein the composition is at least 90 wt. % water. 
     
     
         19 . The composition of  claim 14 , further comprising a non-ionic surfactant. 
     
     
         20 . The composition of  claim 14 , further comprising an unmodified polyethylene glycol of 5 to 18 C 2 H 4  repeat units linked by ether bonds and also comprising a non-ionic surfactant.
