Abstract
Abstract Disinfecting compositions directed to the prevention of microbial infections are disclosed. The disinfecting compositions comprise a protic acid, a metal chlorite and a gelling agent which, when combined, provide an effective adherent matrix that acts as a disinfectant barrier for preventing transmission and propagation of microbial infections. The gelling agent includes at least 25% polyacrylamide. The compositions of this invention may be used as presurgical disinfectants or as antiseptics for wounds and injection, phlebotomy and catheter insertion sites.
