How to keep a perfume formula record you can actually repeat

You know the scene. You are about to buy a fragrance oil, so you post in the group: "Which house did you get this one from, what percentage did you use, which alcohol do you recommend?" Five answers arrive within ten minutes. One says "I did 25% and it came out great", another names a different supplier, a third takes the thread somewhere else entirely. You buy the oil, you try it, it does not work. Three weeks later you are scrolling back through eight hundred messages to find that reply again.

The problem is not that the advice is wrong

The person answering you is usually telling the truth. They really did use 25% and they really were happy with it. That sentence just never turns into a formula you can repeat, because on its own it does not carry enough information.

• The fragrance house is missing. The same perfume's oil is sold under the same name by two suppliers, with different strength and character. A percentage that is right for one sits heavy in the other.
• You cannot tell which calculation the percentage came from. Is 25% volumetric or gravimetric? They are not the same number, and the grams change with the oil's density. The volume versus weight article goes through the difference.
• The alcohol type goes unsaid. Perfumer's alcohol, pharmacy alcohol and a cologne base are not interchangeable. The wrong alcohol ruins even the right percentage.
• Maceration time is skipped. On what day of the blend was it "great"? A one-day blend and a three-week blend do not smell alike; the maceration article covers that gap.
• The message disappears. A group feed is not an archive. Ask the same question three months later and five different people give five different answers.

The four things that make advice reproducible

To rebuild someone else's blend on your own bench you need these four together. Miss one and you are not following a formula, you are guessing.

1. 1The house and the product code. A brand name alone is not enough; the same house can carry two versions of the same perfume.
2. 2The percentage and the kind of calculation. Something like "22% by weight". Putting the method next to the number turns a guess into a measurement.
3. 3The base. A premixed solution, or your own alcohol, water and fixative mix, and in what proportions?
4. 4The time, and the note from that time. How did it smell on day one, week one and week three? This is the valuable part, and it is almost never written down.

Following a person is not the same as searching a group

Esansmatik is not trying to build a community. You already have a group, and there are a few people in it whose judgement you trust. What is missing is a steady place where their experience actually lives.

In the app, every batch is saved with its concentration, its fragrance house, the bottle size and the process notes side by side. You open the batches you choose on your own share page and hand out the link to that page. Whoever has the link reads it without signing in, and who can see it is decided entirely by who you gave the link to.

• Follow. Once you open someone's share link you can follow them. From then on, every batch they log shows up in your feed and you never scroll back through group notifications for it.
• Copy the formula. Instead of retyping percentages from a screenshot, you copy a formula you like into your own notebook in one step and recalculate it for your bottle size. Their note stays as a read-only reference.
• No discovery, on purpose. There is no user search in the app. You cannot stumble across anyone, and nobody stumbles across you. Your following list is made only of people who handed you their link.
• Costs stay private. Your cost and profit per bottle never appear on a share page, and a follower never sees them.

Write down your own batches too

You are the other half of this. The person posting "25%, came out great" today cannot reproduce their own blend three months from now. Record a batch with its percentage, its oil and its date, and you will both know what to change next time and be able to send a link instead of typing a message when someone asks.

If you do not know where to start with the percentage, what concentration to use gives the typical ranges; and if your first blend smells of alcohol, the reason is usually the time, not the formula.
