How this molecule is described

Sources disagree about odour more often than they disagree about chemistry. Rather than show one answer, here is every description on file with how many ingredient records carry it.

Descriptions on file

Ordered by how many independent descriptor streams give each wording, then by how often it appears. The bar is still replication — one source copied onto many ingredients scores high there — so the two can disagree.

Bars are the share of ingredient records carrying each description. High agreement means the sources replicate each other — not necessarily that they are right.

Published thresholds

5 measured values from the literature. Grouped by what was actually measured — a threshold smelled in clean water, tasted in the mouth, or measured in a real food are three different quantities and are not pooled.

Orthonasal, in clean water

3.0 ppb

The reference measurement — smelled in water. OAV is computed against this.

Threshold	Matrix	Source	Paper
3.0 ppb	water_odor	Leffingwell	—

In a food matrix

425 ppb

Measured in a real food, where the matrix shifts detection — not a clean-water value.

Threshold	Matrix	Source	Paper
425 ppb	water (food: reference standard (water))	Literature corpus	—

Retronasal / in-mouth

31.0 ppb

Tasted rather than smelled — a different sense, not comparable.

In air

100 ppb

Airborne detection — not comparable to a water threshold.

Other matrix

20.0 ppb

Measured in a non-aqueous medium (oil, starch, cellulose).

Only values we can attribute are listed. Where a compendium's licence does not permit public attribution its figures are omitted here, so every number on this page traces to a citable source.

Where you'd actually smell it

Odor Activity Value = measured concentration ÷ odor threshold (425.0 ppb, the engine's canonical value — see the 5 published values). OAV ≥ 1 = perceptible.

Concentrations from PubMed Central Open Access papers (free literature corpus, MIT-style licensed). Copper = OAV ≥ 10 (strongly perceptible). Green = OAV ≥ 1 (perceptible).

Measured impact first, then profile share

Every ingredient known to contain 1-heptanol. Ingredients with a measured concentration come first, ranked by odour activity; the rest follow by how large a share of that ingredient's profile this molecule is. The figure beside each is how many different compounds that ingredient has in total — not the concentration of 1-heptanol in it. Full concentrations are in the OAV table above.
