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
Learn how a shared rose theme changes when phenethyl alcohol, geraniol and citronellol are balanced differently.
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 |
|---|---|
| Phenethyl alcohol | 65 |
| Citronellol | 20 |
| Geraniol | 15 |
| Total | 100 |
Study method
- Study the three materials separately using documented evaluation dilutions.
- Enter the relative aromatic percentages in a new formula and choose a small measurable trial.
- Account for every stock strength and solvent before weighing; these percentages are not stock-solution percentages.
- Evaluate the trial on labelled blotters at a recorded dilution appropriate to the materials.
- For a comparison, move five percentage points from phenethyl alcohol to geraniol while keeping citronellol fixed.
What to evaluate
- Which material’s character is easiest to recognize?
- Does the variation change your impression of freshness, sweetness or greenness?
- Which version preserves a clearer rose idea at the later observation?
