Peppermint essential oil in the sanitizer both for its pleasing scent but also because it has antiviral properties. The two remaining ingredients are glycerin and distilled water, both in very small amounts. The sanitizer is packaged in an aluminum spray bottle so it is recyclable and holds 2.25 oz. To use; just spritz a couple of times into the palm of your hand and then rub all over your hands for about 20 seconds.
