Published thresholds

9 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

0.230 ppb – 91.0 ppb

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

In air

170 ppb – 18197 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 (7.3149999999999995 ppb, the engine's canonical value — see the 9 published values). OAV ≥ 1 = perceptible.

Measured impact first, then profile share

Every ingredient known to contain ethylbenzene. 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 ethylbenzene in it. Full concentrations are in the OAV table above.
