Because my mouse is dead and I am lost without it, and am not good at using the touch pad on the laptop...I can't figure out how to quote in my message LOL. So sorry, I am probably all over the place in responding to messages.
Anyway, there are lots of studies on aromatherapy. Just the smell affects a person. Not so much is believed in the power of fragrance in the United States as it is in France... I feel that we are behind the times on this study, whereas France has long been using aromatherapy, even in hospitals to aid healing and well-being.
I don't have any scientific documentation on how well an essential oil properties holds up in soap as far as applying it to your skin. I am going to go with none. But I do know that I healed a fresh burn on my finger nearly overnight by putting a couple of drops of lavender on it and covering it with a band aid...but I wouldn't rub a bar of lavender soap on a burn, even if I made it with lavender EO.
I also know that just the smell of lavender is calming, relaxing, and sleep inducing. So yeah, if I were permitted to make a claim about the smell of lavender in soap, I would put that on my label. Soap retains the AROMA of lavender, so why wouldn't the aromatherapy properties be retained?
Does soap retain the chemical properties in lavender that make it anti-fungal, anti-viral, etc....stay in soap? Probably not. But the aroma sticks, at least for a little while in soap. An aroma can evoke emotions, memories, as well as other stimuli. I woke up this morning groggy because I was up late last night. I made my coffee and didn't even drink it for a while, and I was awake and alert, just because the aroma of coffee was filling the house (don't get me wrong, drinking it helped a lot after lol).
So to respond to the OP, I think that you are trying to find a fragrance that matches the smell you are looking for. I wish you luck. Maybe you can find a dupe or find out what the notes are to recreate it, or at least part of it. My friends husband passed away. Unknowingly I bought her a bunch of these "petals" room fragrance plug ins from bath and body works. She cried because it made her think of her husband. To me, this fragrance and her husbands cologne didn't smell alike in the least. Somehow it did to her...The power of aroma.
