I'm not a chemist, so I prefer to ask this question to some people, who definitely have knowledge in that area.
WHO Handrub Formulation is available here. Ingridients: Ethanol 96%, Hydrogen peroxide 3%, Glycerol 98%, Sterile distilled or boiled cold water.
I would like to use it to produce 4l of handrub (I have 92% alcohol, and I re-calculated needed amounts). Can I also add some essential oil to the formula? Only few drops or more ~10 ml?
- Orange, ingridients: citrus aurantium dulcis peel oil expressed, linalool, citral
- Spruce, ingridients: limonane, linalool, geraniol. INCI: oleum picea excelsa
- Pine, ingridients/INCI: oleum phus silvestris
- Lavender, ingridients/INCI: lavandula angustifolia oil, linalool, limonene
I just want to make sure that the final substance wouldn't be irritating to the hands nor cause any allergies etc. I also found this paper, where they added Piper nigrum Essential Oils to the formula.
Thank you for suggestions.
