on 4/13/17Only the ones that state that they are. Not many from Jade Bloom are best I can tell but I think there may be a blend or two that include a carrier oil, however they also clearly state that. When the bottle simply says 100% Peppermint essential oil for instance that should mean it does not contain a carrier and since this company does list a carrier in one or two cases it indicates to me they abide by this rule. Hope this helps
