Abstract

Provided are alcohol-free antimicrobial compositions comprising benzalkonium chloride, antimicrobial phospholipid, water, and optionally, polyol co-solvent and/or surfactant. Also provided are alcohol-free antimicrobial compositions comprising quaternary ammonium salt, polyol co-solvent and/or surfactant, and water. Preferably, the compositions are formulated for use as a skin sanitizer.

Claims

exact text as granted — not AI-modified
1 - 17 . (canceled) 
     
     
         18 . An antimicrobial composition comprising benzalkonium chloride in an amount of 0.1-2.0% w/w, antimicrobial phospholipid in an amount of 0.1-1.0% w/w, and water in an amount of at least 60% w/w, wherein the composition is alcohol-free and wherein the composition is formulated for use as a skin sanitizer. 
     
     
         19 . The antimicrobial composition according to  claim 18 , comprising benzalkonium chloride in an amount of 0.13%. 
     
     
         20 . The antimicrobial composition according to  claim 18 , further comprising polyol co-solvent in an amount of 0.5-8.0% w/w. 
     
     
         21 . The antimicrobial composition according to  claim 20 , wherein the polyol co-solvent comprises propylene glycol. 
     
     
         22 . The antimicrobial composition according to  claim 20 , wherein the polyol co-solvent comprises a polyethylene glycol. 
     
     
         23 . The antimicrobial composition according to  claim 18 , further comprising surfactant in an amount of 0.05-20% w/w. 
     
     
         24 . An antimicrobial composition comprising benzalkonium chloride in an amount of 0.1-2.0% w/w, antimicrobial phospholipid in an amount of 0.1-1.0% w/w, polyol co-solvent in an amount of 0.5-8.0% w/w, surfactant in an amount of 0.05-20% w/w, and water in an amount of at least 60% w/w, wherein the composition is alcohol-free and wherein the composition is formulated for use as a skin sanitizer. 
     
     
         25 . The antimicrobial composition according to  claim 24 , comprising benzalkonium chloride in an amount of 0.13%. 
     
     
         26 . The antimicrobial composition according to  claim 24 , further comprising polyol co-solvent in an amount of 0.5-8.0% w/w. 
     
     
         27 . The antimicrobial composition according to  claim 26 , wherein the polyol co-solvent comprises propylene glycol. 
     
     
         28 . The antimicrobial composition according to  claim 26 , wherein the polyol co-solvent comprises a polyethylene glycol. 
     
     
         29 . The antimicrobial composition according to  claim 24 , further comprising surfactant in an amount of 0.05-20% w/w. 
     
     
         30 . An antimicrobial composition comprising quaternary ammonium salt in an amount of 0.1-2.0% w/w, polyol co-solvent in an amount of 0.5-8.0% w/w, and water in an amount of at least 60% w/w, wherein the quaternary ammonium salt comprises benzalkonium chloride and a second active agent selected from the group consisting of monoalkyltrimethyl ammonium salts, dialkyldimethyl ammonium salts, heteroaromatic ammonium salts, polysubstituted quaternary ammonium salts, bis-quaternary ammonium salts, and polymeric quaternary ammonium salts, wherein the composition is alcohol-free, and wherein the composition is formulated for use as a skin sanitizer. 
     
     
         31 . The antimicrobial composition according to  claim 30 , comprising benzalkonium chloride in an amount of 0.13%. 
     
     
         32 . The antimicrobial composition according to  claim 30 , further comprising surfactant in an amount of 0.05-20% w/w. 
     
     
         33 . The antimicrobial composition according to  claim 32 , wherein the surfactant comprises cocamidopropyldimethyl betaine. 
     
     
         34 . The antimicrobial composition according to  claim 32 , wherein the surfactant comprises cetyltrimethyl ammonium chloride. 
     
     
         35 . An antimicrobial composition comprising quaternary ammonium salt in an amount of 0.1-2.0% w/w, surfactant in an amount of 0.05-20% w/w, and water in an amount of at least 60% w/w, wherein the quaternary ammonium salt comprises benzalkonium chloride and a second active agent selected from the group consisting of monoalkyltrimethyl ammonium salts, dialkyldimethyl ammonium salts, heteroaromatic ammonium salts, polysubstituted quaternary ammonium salts, bis-quaternary ammonium salts, and polymeric quaternary ammonium salts, wherein the composition is alcohol-free, and wherein the composition is formulated for use as a skin sanitizer. 
     
     
         36 . The antimicrobial composition according to  claim 35 , comprising benzalkonium chloride in an amount of 0.13%. 
     
     
         37 . The antimicrobial composition according to  claim 35 , further comprising polyol co-solvent in an amount of 0.5-8.0% w/w.
