Hi, I'm Stephanie from stehanieknaturals.com and I'm going to tell you about the ratio of essential oils to alcohol in perfume. In my perfumes, I'll always use about twenty percent essential oils to eighty percent alcohol. You can go up to about thirty percent essential oils, but then you might start running into issues with allergic reactions so I keep it down to twenty and it's plenty a strong enough to to have a good, strong scent, and any lower, and then it's it's not so much a perfume. It's more like a cologne, or an EDT. And so use about twenty percent essential oil to about eighty percent alcohol, and that will be a good ratio to use.
