## Abstract

Polymer-based composition effective for disinfecting and for sterilizing plus cleaning and/or lubricating devices. The composition contains, in solution, a hydrophilic polymer serving as a water-based lubricant, a disinfectant, and a surfactant. The addition of a hydrophilic polymer forms an anti-corrosive formula for sterilizing, disinfecting, cleaning, and lubricating devices including medical and dental devices where the efficacy of cleaning and sterilizing is enhanced by the addition of a hydrophilic polymer.
