1. A skin preparatory composition for use with electrocardiograph and electroencephalograph monitoring electrodes, the composition functioning to suitably adhere the electrodes to the skin, to abrade the skin to reduce the impedance thereof to a satisfactory level for use in conjunction with an electrocardiograph or electroencephalograph, and to effectively remove perspiration, dirt, natural body oils, and moisturizing oils and lotions from the skin, the composition consisting essentially of:

  • karaya gum in an amount between about 1 wt % and about 15 wt % so as to adhere the electrodes to the skin and to remove said perspiration, dirt, natural body oils, and moisturizing oils and lotions from the skin;

    sodium citrate in an amount between about 1.5 wt % and about 30 wt % so as to impart sufficient electrolytic properties to said composition thereby rendering said composition useful with said electrodes;

    an abrasive in an amount between about 5 wt % and about 40 wt % effective to reduce the impedance of said skin to said satisfactory level when said composition is applied thereto; and

    an aqueous vehicle in an amount between about 35 wt % and about 85 wt %.
