Published thresholds

4 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.

In a food matrix

1.6 ppb – 58.8 ppb

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

Threshold	Matrix	Source	Paper
1.6 ppb	water (food: unknown)	Literature corpus	38730294, 40241179, 40761387 +1
7.4 ppb	water (food: tea)	Literature corpus	39996838
58.8 ppb	water (food: fish)	Literature corpus	36950329

In air

2500 ppb

Airborne detection — not comparable to a water threshold.

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 (7.39 ppb, the engine's canonical value — see the 4 published values). OAV ≥ 1 = perceptible.

Food	Concentration (ppb)	OAV	Source
tea	7.7	1.04	—

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 cyclohexane. 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 cyclohexane in it. Full concentrations are in the OAV table above.
