Abstract
A liquid biocidal agent that has bacteriostatic and viricidal activities is described. The composition includes about 100 to 400 parts per million sodium polypectate, about 13 to 250 parts per million silver ion, about 4 to 8% glycerine, sufficient base such as ammonium hydroxide to maintain a pH in the range of from about 7.2 to 7.8, and distilled water. The composition is useful for treating Herpes virus, condyloma, and for preventing Staphylococcus aures infection.
