Does anyone know the percentage of water to rubbing to alcohol to make cold packs with zip lock bags that are pliable? Someone told me once, but i have forgotten. I have a patient who needs these, and they are not inexpensive.

Bags of frozen peas are inexpensive, last 10 to 20 minutes, and mold well to your body.
Mix 3 cups (709.78 mL) water and 1 cup (236.59 mL) denatured alcohol in a freezer bag. Seal the bag and place it in freezer until slush forms. Refreeze the bag when the slush melts.
