In short
A minimalist perfume formula uses very few lines, often ten or fewer, so each one has to do visible work. Such formulas tend to be linear and clear, and they leave nothing to hide behind. A short list is not automatically simple, however, since one natural oil can hold dozens of constituents, and it is not automatically better either. The purpose of this lesson is to learn what each material in a formula is really doing.
What you will learn
- Explain what a short formula gains and loses
- Design with ten materials or fewer, each with a stated job
- Use removal tests to justify each material
Before this lesson: Overdose Technique: Study Guide
What you gain, and what you give up
| Gain | Cost |
|---|---|
| Clarity: each material can be followed | Less richness and complexity |
| Easier records, sourcing and restriction checks | A supply problem with one material affects everything |
| A cleaner way to study one idea | Weighing errors are more visible |
| Often a stronger signature | Harder to give a real evolution over time |
A well-known extreme is Escentric Molecules' Molecule 01 (2006), marketed as essentially a single aroma chemical, Iso E Super. That is an argument about what a perfume can be. It is not a template, and our Iso E Super guide explains why that material can carry so much.
A worked plan, on paper
Here is a study design for a clear woody musk, with parts per 100 for illustration. It has not been made or tested by us. Treat it as a starting hypothesis, and check any restriction before you use it.
| Material | Parts | Job |
|---|---|---|
| Bergamot oil FCF | 8 | Opening light |
| Hedione | 25 | Air and bridge |
| Iso E Super | 30 | Soft woody body |
| Virginia cedarwood oil | 7 | Recognizable wood |
| Ambroxan | 5 | Dry warmth, length |
| Habanolide | 25 | Skin-like base |
The parts add to 100: 8 + 25 + 30 + 7 + 5 + 25. Notice what a plan like this cannot tell you. You cannot know from arithmetic whether the bergamot is too brief to form an opening, or whether the musk disappears for some of your assessors.
Removal testing
The core tool of minimalism also works on any formula.
- Make the whole formula, plus a version missing one material, adjusted back to 100%.
- Code them, and compare them at the times you care about.
- If you cannot tell them apart blind, consider removing the material or giving it a new job.
- If removal improves things, keep it out and retest.
- Check again at a later stage, since materials may matter only in combination.
Making a short formula evolve
A short formula can still change over time if its lines span volatilities. Use your volatility records. A top material that vanishes, a middle that bridges and a base that stays can be enough. If the fragrance smells the same at all stages, that may be what you wanted, in which case you are writing a linear fragrance, as the linear and pyramidal guide describes. Either way, you should state which you intend.
Practical exercise: A ten-material formula
- Write one sentence on what the fragrance is about.
- Choose at most ten materials, giving each a job in a single phrase.
- Make the formula, and record it in full.
- Run a removal test on the two materials you are least sure of.
- Decide what stays, then revise, and compare the final version blind with your first.
You have done this well if every remaining material has a stated job and a test behind it, and you can say what the formula gave up by being short.
Common mistakes
- Counting lines rather than constituents. Restriction checks must consider what is in each natural.
- Equating short with good. A short formula still has to smell of something worthwhile.
- Removing by opinion. Test blind.
