In short
The capstone regulatory review applies your Level 10 method to the exact final version of your formula, for one market and one product type, and ends with a plain status note saying what the fragrance may and may not be used for. Most capstones finish with work still outstanding, and that's fine. Say what it is. The danger lies in the gap between a good-smelling fragrance and a finished product that people could safely use.
What you will learn
- Review the final version against one market
- State the formula's permitted status plainly
- Decide what the capstone may be used for now
Before this lesson: Cost Calculation for the Capstone
What to do
- Freeze the version. Name it. Any later change means reviewing again.
- Repeat the compliance review. Reuse your structure, and update each source and date.
- Check the amendment. Has anything changed since you started? See amendment awareness.
- Draft the label. Ingredient list with allergens, as you currently understand them, marked as a draft.
- List what remains. Usually, at the least, a safety assessment, complete supplier data and formal stability work.
The status note
End with a paragraph like this invented one, which you will use in your case study:
V9 is a study composition. By my own calculation on November 9, 2026, against the source versions listed, I found no exceeded limit for a Category 4 product at 15% concentrate. Two naturals lack allergen data. It has had no safety assessment and only informal stability checks. It has been evaluated on strips and fabric only. It is not to be applied to skin or sold.
Notice how much information that gives. A reader knows exactly what has been done.
What you can do from here
| You want to | What you need |
|---|---|
| Share it for study on strips | The status note, and a label saying what it is and how to handle it |
| Present a case study | The note, with the formula itself kept private if you choose |
| Wear it, or give it for wear | A proper safety assessment first, for that use |
| Sell it | Everything on your market route, starting with a responsible party |
| Hand it to a brand | Your documentation and a clear statement of what remains |
It may be tempting to treat one personal use as different. We won't tell you what you do on your own, but this Academy's method doesn't validate skin use. A self-check isn't a safety assessment, however carefully you've done it.
If you find a problem
Suppose a line exceeds a limit you had missed. Do not hide it. Treat it as a real reformulation: make a new version, test it blind against the previous one, and run the evaluation points that matter again. Record this in your iteration log and case study. Finding this before anyone is exposed is exactly what the review is for.
Practical exercise: Capstone review and status note
- Freeze your final version, and run the full review.
- Have someone rework two restriction calculations.
- Draft your label, and mark it as a draft.
- Write your status note, and put it at the front of your capstone file.
- If you found a problem, reformulate and record it.
You have done this well if your note states what has and hasn't been done, your sources are dated, and nothing implies the fragrance has been validated.
Common mistakes
- Reviewing an earlier version. Reviews belong to a version.
- Writing "compliant". Say what you checked instead.
- Dropping the status note from later documents. It should travel with the fragrance.
Safety
This review supports your learning. It does not clear a product for use on skin, for sale or for distribution.
