I've used the Majestic and Sun (and others) essential oils from Amazon. (people give them to me and ask me to make them soap.
I don't have proof from a lab, but I am beyond highly suspicious that those products are not what they claim. At the very least they're a mix of eo and fragrance....at worst they are pure fragrance oil. Soaps with those brands of essential oils have NEVER acted in the manner that soaps with oils from Edens Botanicals or New Directions acted. The results were drastically different each time, strange colors developing, extreme softness, not being to unmold for up to 2 weeks (my recipe takes on average 36-48 hours to unmold.) and greatly extended cure times....only to end up with a soap that just doesn't really smell like an essential oil soap.
I don't trust them and will no longer use them to make soap for anybody. Nor will I support a dishonest business.
The cost per 4 ounce bottle is very appealing since the price of eo's seems to have one direction only - up. However, you'll have to consider the consequence to the people using the soap who might have an allergy to synthetic fragrance. They'll need that info on your soap label which, won't be there because your supplier lied to you. (assuming I'm correct about these eo's being bogus)
