First of all, I think you should take any chemistry discussion on a DIY Perfume sub with a massive grain of salt. I've seen posts recently, purporting to educate on the chemistry of perfumery. They use a lot of chemical terms and maybe even some of them correctly. But mostly, the information is just "science-adjacent," that isn't helpful. A recent example:
There was a recent post about a lot of chemistry things, but the one that stood out to me was talking about "Linalool flood." This is not a thing. Linalool doesn't create a "waxy matrix layer," that "prevents volatiles from escaping."
We see a whole bunch of ideas like this that take something that sounds chemistry-related but isn't actually based in chemistry. Or even if there is some grain of truth there, it's much too simplistic. It reminds me of the way my father-in-law thinks of medical issues when he talks to my wife, a doctor. "Mija, just give me the antibiotics because the pain in my knee is caused by bacterias attacking the joint." Uh, sure, Dad . . . I guess we just ignore the arthritis damage evident on x-rays, lol.
For all practical purposes in home-based perfumery, chemistry knowledge isn't going to help you craft a perfume. Yes, there are intermolecular forces at work in every solution with multiple chemicals. Knowing what these are is very interesting information. I love learning about any scientific knowledge. As amazing as the world of molecules is, you actually have an excellent, built-in measurement instrument that can detect the entire range of relevant information in regards to perfume creations. Your brain can use its sensory extension called your olfactory system to tell you when something is off. Your brain can use this information to learn to judge which materials tend to suppress others, which enhance each other, when a perfume doesn't smell right, when it's too soapy/strong/muddy . . .
It's not "linalool flood," that causes a problem, it's a simple matter of having an unbalanced perfume. You can have too much linalool, sure. So use a little less.
The bottom line is that, it is not necessary to understand chemistry in order to make your own perfumes. Indeed, trying to apply superficial and most likely erroneous knowledge of chemistry is just going to confuse the whole endeavor. We should definitely take a scientific approach to our craft -observe, experiment, record, rethink and repeat. Just don't bog your mind down trying to make sense of the very complex subject of chemistry.
