A LITTLE CARE GOES A LONG WAY

Using it thoughtfully

Read the full safety context before bringing this oil into your routine.

Cited dermal maximum · leave-on: 8%
Phototoxicity: Not flagged in this profile
Oxidation risk: medium

A cited maximum is a limit, not a suggested dilution. Missing restrictions do not establish safety.

TGSC's bergamot-leaf entry gives a bergapten guidance note rather than a leaf-oil phototoxic warning, and Hermitage describes the material as steam-distilled leaves rather than expressed peel; no public source reviewed in this pass identified a phototoxic leave-on ceiling for bergamot leaf oil itself.

Contraindications & cautions

moderateUse within the published fragrance-usage guidance because the material contains sensitizing restricted components including citral, geraniol, citronellol, and linalool-bearing fractions.

THE SCIENCE BEHIND THE SCENT

Inside the oil

8 constituents

An oil's character comes from its natural chemical composition. Explore each constituent to understand the connections.

About this composition

Hermitage identifies this seasonal material as small-scale Italian steam-distilled bergamot leaf oil. Public bergamot-leaf chemistry sources agree that petitgrain bergamotier is much more oxygenated than bergamot peel oil and is centered on linalyl acetate and linalool, with smaller alpha-terpineol, limonene, beta-pinene, gamma-terpinene, geranyl acetate, and neryl acetate fractions. The archive record keeps directly readable quantitative values from Turkish bergamot leaf oil literature and the TGSC bergamot-leaf entry's bergapten/citral notes for safety context.

What we're still learning · 3 data gaps

Good decisions start with knowing what is — and isn't — in the evidence.

The public 8% maximum comes from TGSC's fragrance-concentrate usage guidance for bergamot leaf oil, not a directly readable category-5A finished-product IFRA certificate for this exact seasonal Hermitage lot.
Odor intensity 85 is an archive normalization of Hermitage's 'very powerful' aromatic description rather than a directly published 0-100 measurement.
Missing public source type for stronger compositional certainty: a directly readable full GC-MS or COA tied to the exact Italian seasonal lot sold by Hermitage rather than open bergamot-leaf literature summaries and database extracts.
