Published thresholds
2 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 water, medium unconfirmed
10.0 ppbReported as water, but the medium could not be confirmed from the source — not used for OAV.
| Threshold | Matrix | Source | Paper |
|---|---|---|---|
| 10.0 ppb | water (unverified; relabelled from air, audit 2026-10-14) | PMC open access | — |
Other matrix
1890 ppbMeasured in a non-aqueous medium (oil, starch, cellulose).
| Threshold | Matrix | Source | Paper |

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.
Thresholds in published tables
Numbers printed in open-access papers, grouped by the medium the table states. Median and full range of the values; “agree” means two or more papers whose middle 80% of values sit within 100×. Not reviewed.

|---|---|---|---|---|---|
| air | 6400 µg/L air | 41.9–6.4e+03 | 4 | 2 | no (2.2 decades) |
| ethanol solution | 1890 ppb | 1.89e+03–1.89e+03 | 4 | 4 | yes |
| food matrix | 25 ppb | 0.5–6.4e+03 | 6 | 6 | no (3.4 decades) |

Measured impact first, then profile shareEvery ingredient known to contain hexyl caproate. 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 hexyl caproate in it.
