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: 2%
Phototoxicity: Phototoxic — use caution
Maximum for sun-exposed skin: 2%
Oxidation risk: high

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

Cold-pressed lemon is phototoxic. AromaWeb cites Tisserand and Young's dermal maximum of 2.0% for cold-pressed lemon oil to avoid phototoxic reaction.

Contraindications & cautions

majorKeep at or below 2% in leave-on products exposed to UV because expressed lemon oil is phototoxic.

About this composition

This record is anchored to a public organic lemon peel COA with GC data. It is a limonene-dominant expressed peel oil with beta-pinene and gamma-terpinene as the main secondary constituents and smaller amounts of alpha-pinene and myrcene. Citrus & Allied's lemon overview also notes that expressed lemon oil composition varies by variety and region but is characteristically built from limonene, aldehydes, alcohols, and sesquiterpenes, with citral as a characterizing aroma component.

What we're still learning · 3 data gaps

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

The public COA supports the limonene-dominant cold-pressed profile directly, but the chemotype wording 'monoterpene hydrocarbons ~92%' is an archive summary label rather than a phrase printed verbatim in the COA.
Odor intensity 80 is an archive normalization from AromaWeb's qualitative strength label 'Strong' and its aromatic description, not a native published 0-100 measurement.
No public source located in this pass gave directly measured volatility-rate or tenacity-hour values for this lemon profile.
