Hi! I'm a chemist. I've formulated (figured out how to make on a huge scale) things like mouthwash--and I have to tell you, I hadn't thought of this one and we hadn't come across it at the companies where I've worked. You actually have a great idea for bad breath. The fat in the coconut can dissolve a chemical called cadaverine, which was named after the way it smells. That's a really good thing not to have on your breath. Thanks for posting this, and I'm following you!
