Described herein are compositions having durable antimicrobial activity. Durable antimicrobial compositions include carbonate / bicarbonate salts of quaternary ammonium cations, organic acids, hydrogen peroxide, surfactants and cationic polymers. Cationic polymers include (3-acrylamidopropyl) trimethylammonium chloride monomers or [2- (acryloyloxy) ethyl] trimethylammonium chloride monomers. The cationic polymer also includes another monomer selected from polar water soluble monomers, hydrophobic silicone-containing monomers or mixtures of the two types of monomers, in combination with one trimethylammonium chloride monomer. The surfactant is selected from cationic surfactants, nonionic surfactants, amphoteric surfactants and combinations thereof. |
