Not in FEMA GRAS publications 1-33. Of 3,367 listed flavoring substances, none match this compound name. May still be food-safe under other regulatory routes (FDA 21 CFR 172, EFSA, JECFA) — check femaflavor.org for the authoritative current list.

Published thresholds

3 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

2.7 ppb – 45.0 ppb

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

Threshold	Matrix	Source	Paper
2.7 ppb	water (food: unknown)	Literature corpus	22417543, 23758650, 25879935 +13
4.8 ppb	water (food: tea)	Literature corpus	36323840
45.0 ppb	water (food: soy sauce)	Literature corpus	17898513

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 (4.85 ppb, the engine's canonical value — see the 3 published values). OAV ≥ 1 = perceptible.

Measured impact first, then profile share

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