  • Antimicrobial solutions and methods
    Patent number: 8846067
    Abstract: Antimicrobial solutions and delivery systems for them use liquid antimicrobial solutions with: at least 80% of total weight of a carrier liquid comprising water, alcohol or a mixture of water and alcohol; at least 0.0001% by weight of the solution of I2; at least 0.0001% by weight of CuSO4; and sufficient acid in the solution top provide a pH of less than 7.0. A buffering system is also preferable in the solution, and the solution may be provided directly to wounds, burns or other skin damage as a liquid, as a spray or as a gel.
    Type: Grant
