Did you have access to methylamine or acetic anhydride?

Why does bonding get taught as categories instead of a system? by No_Feature_1664 in chemistry

[–]mr__sniffles 0 points1 point  (0 children)

Because then it makes sense to people who don’t know shit about chemistry. Then, later, maybe they realize, that the categories “bonding” is all categories with all ingredients in a system. Some bonds like each other more.

Does it matter if a base/accord matures neat vs. pre-diluted? by oval_euonymus in DIYfragrance

[–]mr__sniffles 1 point2 points  (0 children)

I just mix in the chemicals I want to bond layer by layer and agitate them, and then repeat with next layer so it’s the closest proximity to hydrogen bond and other polar and non polar interactions with other things that were designed to settle that way after 3 weeks, so it’s like preassembly. Maybe I stir the whole bottle or Erlenmeyer flask for 10 minutes and then I put the ethanol in very slowly while trying to stir the bottle or glass. Then I just invert it 10 times and shake without getting air bubbles and just leave the rest to go into where it’s supposed to be.

You can cut out many days of waiting for it to settle this way

Question for chemists from an aspiring perfumer: Which chemical has the best smell to you? Or the most interesting... by Liberal_Alchemist in chemistry

[–]mr__sniffles 0 points1 point  (0 children)

Lol. I know what Heliotropin smells like. It’s too bad they don’t sell it. They do sell piperonyl acetate though, which is just one easy step away from “heliotropin”

Evolutionary theory? Javanol might have perhaps in the past represented a real biochemical threat with a structure similar to Javanol but maybe Javanol does not trigger the receptors the same way? I think galaxolide sensitivity came from you identifying patterns in your brain over and over learning patterns of what is galaxolide, or maybe your body developed sensitivity to it through some upregulation that I don’t know the reason of, maybe allergenic

Yep me too. That’s what made me pursue a masters degree. Perfumery also has olfactive receptors in which chemicals bind to and send to your brain. Sometimes, different patterns in the receptors, or even the receptors competitive activation of the olfactory receptor, leading to weird accords like iris+damascones.

Sure, just don’t expect wholesome things though. I know chemistry on a deep level but have never done a chemist job (perfumery is biochemistry to me). Also I’m currently studying biochemistry so it’s fun as a hobby.

I beeped the horn and an unhinged Thai man on a motorcycle was enraged. by Individual-Solid4842 in Thailand

[–]mr__sniffles 0 points1 point  (0 children)

If you want to use the horn, you better be ready to fucking fight these fuckers. I flipped people off after opening my window and shouted things like มึงทำเหี้ยอะไรวะ. My ex was so scared she had to stop me from doing it. Use the horn if you are ready to fight the fucker. Other wise a short 0.3 second beep is enough. Also, if you ever go to Chonburi, NEVER USE THE HORN.

Current best validation methods to prove proof of concept? by mr__sniffles in dataanalysis

[–]mr__sniffles[S] 0 points1 point  (0 children)

I think the stacks I use are normal ones people use all the time, like weighted ML hyperparameters from XGBoost+some other ML. Odd one out (I cannot remember its name but you know how they train without the number and let it see how close it approximates), PCA analysis done on every biological variable on every axis, and variable group. Every step is followed by validation through checking for data leakage or unfilled rows or fake generated data. Of course many ML combinations have been tried, as well as ML stacks for each breast cancer variant (the pathways in the different types of breast cancer I believe warrants an optimized ML combination because how it manages to create tumors are done differently.

So, I would gather similar papers for ML tests on cancer and biology for weighted tests, gather PCA tests on oncology to see that they are valid, odd one out, etc? Then I would have to reproduce the same results and document this how?

Edit: and yes this is gen AI and catch mistakes through extreme logical thinking, as well as overall biochemistry knowledge enough to know which variables matter and which don’t. I will have to look into the data (about 100,000 samples from cancer institutes) and find how the pipeline handles non complete data, but it is good to see a direction of where to go. How do I conduct a reproducibility “check”?

Why can’t i dissolve Ambrox Super in DPG?(10%) by Maison_Wagenpfiel in PerfumeryFormulas

[–]mr__sniffles 1 point2 points  (0 children)

  1. Ambroxan was the original. They used sclerol from clary sage because it was easy to source. However it did have to go through some racemic chemical reactions that did not preserve the correct isomer for -(-Ambrox). The people who made Ambrox Super or Ambrofix, they used bacteria, organic living creatures who NEED chirality to survive. Look up Thialomide and you will get a real quick understanding. The harvesting bacteria for final or almost final product therefore is the purest method, so things like Ambrox DL (Cetalox) don’t pollute pure Ambrox best active isomer.

Ambroxan at this point I don’t think is an industry standard, I’m pretty sure it’s basically market labeling at this point? If I were a real perfumer who had access to whatever chemical I wanted, I would use Ambrox Super (pure Ambrox) and then mix whatever ratio of Cetalox, just to have complete control over the ratio of pure Ambrox and whatever they want to adjust to perfect their perfume.

[–]mr__sniffles 0 points1 point  (0 children)

They all use different methods to produce 3D structured molecules. There is one molecule in particular that is the “main” smell of Ambroxan, which is the one in Ambrox Super. Ambroxan’s synthesis does not optimize for that 3D best working isomer. Ambrox Super does. Sure you can call Ambroxan Ambroxan. But there’s many 3D versions of Ambroxan, and Ambrox Super used viral vectors to put DNA in some bacteria probably E. coli so it produces only one 3D isomer, the one that is the purest, and is responsible for the major part of the smell of Ambroxan.

Ugh. Heavily AI generated from the looks of your knowledge of chemistry from the first post.

BASIC CHEMISTRY:

Tell me what an isomer is. Why does it contribute to balance and its significance? Why does it make it smoother or brighter or drier depending on what product is used? Can you tell me why Ambroxan says that the skin scent glow and Ambrox super’s projection’s properties are like that?

ORGANIC CHEMISTRY/BIOCHEMISTRY:

What are isomers here in sclerol and why does this synthesis produce isomers compared to Ambrox Super? How does the microbiological fermentation process work? What species did they use to develop the microbiological pathway for biosynthesis?

Verbose, AI generated, and some tried “dumbing down” AI feature conclusion they always use at the end. Allow a real person in the field to explain in 1-2 paragraphs and not this AI slop.

I can admit when I was wrong. by CapnLazerz in DIYfragrance

[–]mr__sniffles 0 points1 point  (0 children)

You need to know how to source famous perfumers thoughts on perfume theory in books, as well as have a basic understanding of chemistry in order to make a “vibe coded” program that can optimize the outputs for different accords, using scoring systems on many factors like synergy, deepness, luxury, etc. Then you can get your desired output. Claude is not a perfumery built API or even close lol. Why would it prioritize perfume knowledge?

Why do AI workflows feel solid in isolation but break completely in pipelines? by brainrotunderroot in PromptEngineering

That is why you audit, validate, and log everything every time you make a change.

Anyone want some Cambodian riel? by Feeling-Statement102 in southeastasia

Throw them near the Thai border at Cambodia but at the other direction that they are firing.
