  • 10 drops Tea Tree Melaleuca alternifolia essential oil

using 91% isopropyl alcoholfinished hand sanitizer contains approximately 75.5% alcohol

  • 13/16 cup isopropyl alcohol (91%) – this is 3/4 cup plus 1 tablespoon
  • 2 teaspoons hydrogen peroxide (3%)
  • 1 teaspoon glycerin
  • 20 drops Ravensara Ravensara aromatica essential oil
  • 20 drops Thyme Thymus vulgaris essential oil, linalool chemotype
  • 20 drops Cape Chamomile Eriocephalus punctulatus essential oil
  • 10 drops Tea Tree Melaleuca alternifolia essential oil
  • 10 drops Lemon Citrus limon essential oil
  • 4 teaspoons distilled water

Instructions

In a pint-sized lidded glass jar, gently swirl together the isopropyl alcohol and the hydrogen peroxide. Add the glycerin and essential oils, screw on the lid, and shake or swirl gently until the glycerin is dissolved.

If using 91% isopropyl alcohol, add the 4 teaspoons distilled water and swirl again.

Divide the mixture evenly between two clean 4-oz spray bottles using a pipette or a mini-funnel to prevent spills. (Each bottle will be between 3/4 and 7/8 full.)

Screw on the caps, then label the bottles, including the date on which you’ve made the sanitizer. Let the bottles sit for 72 hours before use to allow time for any spores or other contaminants within the mixture to be destroyed.

To use, shake well, then spritz generously on your hands and rub over all sides and surfaces of your hands. Rub until hands are dry.

Cautions: Do not spray on the face or near the eyes. Keep out of the reach of children.

Notes

If you don’t have 70% isopropyl alcohol, you may use any alcohol that is at least 70% alcohol.
