Original, untested educational sketch for documented blotter studies. Percentages describe the relative masses of the named undiluted aromatic materials, not a ready-to-wear perfume. No finished-product safety, stability or IFRA conformity assessment has been performed. Account for stock solvents if substituting diluted materials and follow supplier handling guidance.
STUDY OBJECTIVE
Observe how benzyl acetate changes a methyl dihydrojasmonate-led composition.
Formula proportions
These are undiluted aromatic parts totalling 100. The builder initially assumes neat materials (100% stock strength). To preserve these aromatic ratios with diluted stocks, divide each material’s parts by its stock fraction before scaling: 10 neat parts at 10% strength require 100 stock parts. Changing only the stock-strength field changes the aromatic ratio; it does not adjust the amount weighed.
| Material | Relative parts |
|---|---|
| Methyl dihydrojasmonate | 70 |
| Linalool | 20 |
| Benzyl acetate | 10 |
| Total | 100 |
Study method
- Record the exact methyl dihydrojasmonate grade; do not silently substitute a high-cis product.
- Prepare a formula record on an undiluted-aromatic basis and account for any working stocks.
- Evaluate a small trial on blotter under documented conditions.
- Make a second study at 75:20:5 by shifting five percentage points from benzyl acetate to methyl dihydrojasmonate.
- Compare both studies using the same dilution and observation schedule.
What to evaluate
- Does the second trial seem less fruity?
- Can you distinguish a clear flower association from a more general floral impression?
- Which differences survive after the opening?
Record this trial
Keep a separate journal entry for each revision, dilution, and study date.
