Adding essential oils to unscented (baby mild) dr bronner's? - patchouli soap

I've heard that you can essential oils, the baby, Dr. Sweet add. Bronner's to create their own fragrances. (with no detergent) as an institution. have patchouli lotion, but no soap makes me sad. So I ask myself whether I have a bottle of 32 ounces (liquid, of course) doc Bronner, how much essential oil should I add? In addition, the effect of the soap itself in any way?
