A white floral, indolic · the worked cases

Worked out when the page was built

The HTML equivalents of the accord’s two tools, for reading without JavaScript. Back to A white floral, indolic.

What happens if… every single change, worked out

The same model, run when this page was built. Figures are modeled: parts, and shares per 100 parts; odour space is the share of the accord whose components carry each word; the dry-down uses the half-lives top 1.5 h, heart 6 h, base 12 h (the simulator’s site constants, not measurements); odour activity is share ÷ measured threshold, compared within one medium and unit, never across (a teaching ratio, not a measurement of this accord). This teaching accord is not a finished product and is not assessed. Nothing is for sale.

Double jasmine absolute (×2)
1 · Composition
jasmine absolute 45 → 90 parts (45.0 → 62.1 per 100); the others ×0.69.
2 · Molecules
with jasmine absolute rise indole (no shares on record).
3 · Odour space
“animalic” 45.0 → 62.1, “narcotic” 48.0 → 64.1, “floral” 67.0 → 77.2, “jasmine” 30.0 → 20.7.
4 · Perceived character
A modeled reading, not a prediction: more “animalic” and “narcotic” and less “jasmine” and “citrus”.
5 · Dry-down
top / heart / base 0.0 / 97.0 / 0.0 → 0.0 / 97.9 / 0.0; half gone at 6.0 h (unchanged); no class on record, left out: indole. The curve cannot move: every component with a class is heart.
6 · Odour activity
jasmine absolute: no threshold on record.
7 · Regulation flags
The accord’s flags do not change.
Why did this change matter?
  1. Components carrying “animalic” go from 45.0 to 62.1 per 100 parts, because jasmine absolute carries it (its descriptors field).
Remove jasmine absolute
1 · Composition
jasmine absolute 45 → 0 parts (45.0 → 0.0 per 100); the others ×1.82.
2 · Molecules
with jasmine absolute leave indole (no shares on record).
3 · Odour space
“animalic” 45.0 → 0.0, “narcotic” 48.0 → 5.5, “floral” 67.0 → 40.0, “jasmine” 30.0 → 54.5.
4 · Perceived character
A modeled reading, not a prediction: more “jasmine” and “citrus”, less “narcotic” and “floral” and no “animalic” left.
5 · Dry-down
top / heart / base 0.0 / 97.0 / 0.0 → 0.0 / 94.5 / 0.0; half gone at 6.0 h (unchanged); no class on record, left out: indole. The curve cannot move: every component with a class is heart.
6 · Odour activity
jasmine absolute: no threshold on record.
7 · Regulation flags
Flags leaving the accord: Regulation (EU) 2023/1545 (labelling of fragrance allergens).
Why did this change matter?
  1. It takes the “Regulation (EU) 2023/1545 (labelling of fragrance allergens)” flag (a labelling condition, extended to more fragrance allergens) off the accord: it names jasmine absolute and no other component.
  2. jasmine absolute carried “animalic” and no other component does on record, so the word leaves the modeled profile.
  3. Components carrying “narcotic” go from 48.0 to 5.5 per 100 parts, because jasmine absolute carries it (its descriptors field).
Double benzyl acetate (×2)
1 · Composition
benzyl acetate 30 → 60 parts (30.0 → 46.2 per 100); the others ×0.77.
2 · Molecules
benzyl acetate itself rises.
3 · Odour space
“jasmine” 30.0 → 46.2, “floral” 67.0 → 51.5, “narcotic” 48.0 → 36.9, “animalic” 45.0 → 34.6.
4 · Perceived character
A modeled reading, not a prediction: more “jasmine” and less “floral” and “narcotic”.
5 · Dry-down
top / heart / base 0.0 / 97.0 / 0.0 → 0.0 / 97.7 / 0.0; half gone at 6.0 h (unchanged); no class on record, left out: indole. The curve cannot move: every component with a class is heart.

The accord’s flags do not change.
Why did this change matter?
  1. Components carrying “jasmine” go from 30.0 to 46.2 per 100 parts, because benzyl acetate carries it (its descriptors field).
Remove benzyl acetate
1 · Composition
benzyl acetate 30 → 0 parts (30.0 → 0.0 per 100); the others ×1.43.
2 · Molecules
benzyl acetate itself leaves.
3 · Odour space
“jasmine” 30.0 → 0.0, “floral” 67.0 → 95.7, “narcotic” 48.0 → 68.6, “animalic” 45.0 → 64.3.
4 · Perceived character
A modeled reading, not a prediction: more “floral” and “narcotic” and no “jasmine” left.
5 · Dry-down
top / heart / base 0.0 / 97.0 / 0.0 → 0.0 / 95.7 / 0.0; half gone at 6.0 h (unchanged); no class on record, left out: indole. The curve cannot move: every component with a class is heart.
6 · Odour activity
benzyl acetate: no threshold on record.
7 · Regulation flags
The accord’s flags do not change.
Why did this change matter?
  1. benzyl acetate carried “jasmine” and no other component does on record, so the word leaves the modeled profile.
  2. Components carrying “floral” go from 67.0 to 95.7 per 100 parts, because benzyl acetate, which does not carry it, now takes less of the accord.

7 · Regulation flags
The accord’s flags do not change.
Why did this change matter?

7 · Regulation flags
The accord’s flags do not change.
Why did this change matter?
  1. The modeled dry-down moves: heart-class components go from 97.0 to 94.2 per 100 parts (indole has no class on record, so the curve moves with the others’ shares alone).
  2. Components carrying “fecal” go from 3.0 to 5.8 per 100 parts, because indole carries it (its descriptors field).
Remove indole
1 · Composition
indole 3 → 0 parts (3.0 → 0.0 per 100); the others ×1.03.
2 · Molecules
indole itself leaves.

7 · Regulation flags
The accord’s flags do not change.
Why did this change matter?
  1. indole carried “fecal” and no other component does on record, so the word leaves the modeled profile.
  2. The modeled dry-down moves: heart-class components go from 97.0 to 100.0 per 100 parts (indole has no class on record, so the curve moves with the others’ shares alone).
  3. Components carrying “floral” go from 67.0 to 69.1 per 100 parts, because indole, which does not carry it, now takes less of the accord.
