| Résumé : |
A disinfectant composition having prolonged activity against microorganisms contains a biocide, particularly chlorhexidine or biguanide such as polyhexamethylene biguanide, in combination with a film-forming component including polyvinyl alcohol, polyvinyl pyrrolidone or polyalkylene glycol, and optionally a tertiary amine. The disinfectant composition forms a film on a hard surface that is abrasion resistant and exhibits biocidal activity over an extended period of time while being fully dispersible in water. |
