Abstract

The present disclosure provides an antimicrobial composition that includes: an antimicrobial component having at least one quaternary ammonium compound; a synthetic polymer that includes: at least one cationic monomer Ab, optionally, at least one anionic monomer Ba, and optionally, at least one non-ionic monomer Ca; an organic acid; and a surfactant selected from cationic surfactants, amphoteric surfactants and combinations thereof; and at least one non-ionic surfactant selected from the group consisting of low hydrophilic-lipophilic balance (HLB) non-ionic surfactants with a delocalized electronic structure that have moderate to poor water solubility. This composition when applied to a surface demonstrates good cleaning ability and provides robust long lasting disinfection.

What is claimed is: 
     
         1 . A hard surface treatment composition comprising:
 a. an antimicrobial component comprising at least one quaternary ammonium compound;   b. a synthetic polymer comprising:

 ii. optionally, at least one anionic monomer B a , and 
 iii. optionally, at least one non-ionic monomer C a ; 
   c. an organic acid;   d. a surfactant selected from the group consisting of cationic surfactants, amphoteric surfactants and combinations thereof; and   e. and at least one non-ionic surfactant selected from the group consisting of low hydrophilic-lipophilic balance (HLB) non-ionic surfactants with a delocalized electronic structure that have moderate to poor water solubility.   
     
     
         2 . The composition of  claim 1 , wherein a film formed from the composition kills at least 95% of microorganisms for at least 3 abrasion cycles according to RSS-12h. 
     
     
         3 . The composition of  claim 1 , wherein the antimicrobial component is selected from the group consisting of monoalkyldimethylbenzyl ammonium salts, dialkyldimethyl ammonium salts, and combinations thereof. 
     
     
         4 . The composition of  claim 1 , wherein the monomer A b  is selected from the group consisting of diallyldimethylammonium halides. 
     
     
         5 . The composition of  claim 1 , wherein the polymer comprises monomer B a  selected from the group consisting of acrylic acid, methacrylic acid, and combinations thereof. 
     
     
         6 . The composition of  claim 1 , wherein the polymer comprises monomer C a  selected from the group consisting of 2-(dimethylamino)ethyl methacrylate (DMAEMA); N-vinyl pyrrolidone (NVP); N-vinylimidazole; acrylamide; methacrylamide; alkyl acrylate; and combinations thereof. 
     
     
         7 . The composition of  claim 1 , wherein the organic acid is selected from the group consisting of citric, malic, maleic, lactic, succinic, glutaric, adipic acids and combinations thereof. 
     
     
         8 . The composition of  claim 1 , wherein the surfactant comprises a cationic surfactant selected from the group consisting of cationic amine oxides. 
     
     
         9 . The composition of  claim 1 , wherein the surfactant comprises an amphoteric surfactant selected from the group consisting of sultaines, taurates, and combinations thereof. 
     
     
         10 . The composition of  claim 1  further comprising a polar solvent. 
     
     
         11 . A method of providing a surface with residual antimicrobial action that comprises the step of applying the composition of  claim 1  to the surface. 
     
     
         12 . A substrate with residual antimicrobial action comprising a substrate wherein at least a portion of the substrate is coated with the composition of  claim 1 . 
     
     
         13 . The use of a composition of  claim 1  to substantially reduce or control the formation of microbial colonies on or at a surface. 
     
     
         14 . The use of  claim 13 , wherein a film formed from the composition kills at least 95% of gram-positive bacteria and gram-negative bacteria, or enveloped and non-enveloped viruses according to a modified version of Environmental Protection Agency (EPA) Protocol #01-1A residual self-sanitizing activity test.
