Actually, I have a long list of EOs. LOL! - Sweet Orange, 5-fold - Lavender - Lemongrass - Peppermint - Lime (steam distilled) - Rosemary - Vanilla (I think this is mixed w/jojoba oil...have to double check cause I've seen so many) - Rose (either absolute or Otto - both are not FCC, but it makes a nice "flavor") - Coffee CO2 (can't remember if this is FCC) - Bergamot FCF (not FCC, but safe to use in the sun) - Ginger - possibly cardamon & clove...not sure yet. I like to eucalyptus, but I know that may be too strong. Plus, only eucalyptus smithii (sp) is safe for children & elderly, but I don't think it's FCC. I'm not making lip balms specifically for children or the elderly, but I want it to be safe just in case they use them. BTW, I would love to use Lemon, Pink Grapefruit, Tangerine, & Mandarine, but I know they cause photosensitivity.
