First off I want to say congratulations on the beginning of your journey making perfume. Second off, I want to say I'm sorry you've come across that information that's been commonly blow horned that you need synthetics to make a proper perfume because that is absolute bollocks. True, naturals will not have the sillage and longevity of synthetics. Asking yourself what is the goal of your perfume? People do not consider that the desire for a longer lasting perfumes & ones so strong that announce themselves before they even enter a room are frying peoples olfactory receptors and limiting perfumers ability to create creative and nice perfumes with-naturals because it is those fragrances that have high impact aroma, chemicals that are drowning in out the naturals. Naturals are the soul and life of the perfume-in music we can think of the sound of a acoustic guitar, voice or violin..Aroma chemicals can be the additional structure, and like in music can reach octaves or provide instrumentation that the acoustic-such as a synthesizer, effects processor reaching ranges an acoustic cannot provide so it can lead to additional artistic use. But you may often smell this in synthetic perfumes(lore, hear it as I'm are using this music example) if everyone's using the same few aroma chemicals for the smell of rain Petrichor pretty much we're getting the same "song "smelled all over the place. A lot of the time I find people are not being very creative and relying on these verses turning to naturals naturals which challenges the perfumer to use creatively what they have to express more personally. People tend to put the cart before the horse, jumping to copying formulas to make their perfumes before the absolute essential, which is smell training. How old is someone supposed to make a Perfume if they don't know what the material smell like? These problems are huge when it comes down to making perfumes because something won't be smelling wrong in the perfume in the perfume and won't know what it is to be copying formula and a lot of the times the formulas are incorrect. Natural materials and I agree natural perfumery is much more difficult because one must have the actual patients to smell the materials and they can be textually challenging, such as they are sticky residents that must be diluted. I gave this as some advice as a primer it might be helpful smell training primer :)

I do not suggest moving to a synthetic aroma chemical kit until you familiarize yourself with the basics of naturals because aroma chemicals are very taxing to the olfactory nerves, and at this point he want to strengthen them as much as possible. You first want to start with single materials and then you can exercise further by olfactory differentiate and think simulator in your own words and perspective, be able to know between materials. Just for example: when one smelled a Yuzu what are you smelling that makes you think personally it smells different or alike a pink grapefruit (or other citrus you have) or Dark patchouli from Cypriol, Sandalwood from Amyris-This is helpful so you will know how each one affects your composition, and MOST importantly, "direct impact and evaporation" -which is how strong a scent is when you first encounter it on a scent strip , or on your arm and all of what you smell until it fades . This is an exercise. Hopefully you will do as much as you can if you are working hard-it will save you so so much headache in the future, and I have apprentice to established perfumers coming to me with problems with their perfumes it is because they have not done this enough. The interaction between materials -how do you choose to put them together to create a perfume- this process is the fundamentals of perfumery and with your own unique, creative sensibilities you will find a lot of creative fulfillment and create perfumes people will want to experience. Any quick giveaway is you may notice in Fragrances fresh perfumes tend to not last long that is because they have a lot of high impact , short diffusive materials- for example, citrus it will give you quite the presentation at first, but then fade quickly. And then on the alternate spectrum, you can think of labdanum which is used to make an amber accord- it wasn't quite give the nose the impact, but it will last on a scent strip much longer- same with patchouli- and in the middle, you can guess there are the heart notes such as florals predominantly some woods and if you want to get more complex particular distillations, but let's not go there right now. I wish you great fun on your journey. And have fun. https://www.edenbotanicals.com/natural-perfumery-basics.html Hey Siri
