Compositions comprising quaternary ammonium compounds and dendritic polymers with antimicrobial activity

Abstract

The present invention provides compositions comprising quaternary ammonium compounds and dendritic polymers, which can be applied to hard surfaces. The compositions form transparent films and do not cause any unsightly residue on the surface to which is applied. The compositions provide immediate antimicrobial efficacy upon application as well as residual antimicrobial activity, especially broad-spectrum efficacy over prolonged periods, and may be used at low levels to prevent toxicity problems to the user. The film is water-soluble, easily removed completely with warm water, and does not require special techniques or harsh chemical treatments to effect its complete removal. The present invention also provides a method of disinfecting a substrate, preferably a hard surface, comprising applying a disinfecting composition of the invention to the substrate.
