LONG LASTING DISINFECTANT CLEANING COMPOSITIONS AND METHODS OF USE THEREOF
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 A b , optionally, at least one anionic monomer B a , and optionally, at least one non-ionic monomer C a ; 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.
