It was found in our laboratory that anomalous rubber-like hydrogel is prepard by repeated freezing of aqueous poly (vinyl alcohol). The hydrogel can be sterilized by means of γ-rays or disinfectants such as chlorhexidine and benzalkonium chloride. In this study, the adsorption of aqueous chlorhexidine onto the gel was examined. Employing 0.1% chlorhexidine, adsorption equilibrium was almost established in 2 hours. After immersing the fully adsorped gel twice in water of fifty-fold amount, further elution of chlorhexidine was reduced to 0.9〜1.5 ppm. Potassium permanganate consumption of warmed extract was 0.2 ml ; which is far below the restricted value of 2.0 ml for medical materials.
