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: 0.66%
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.

Not a furocoumarin-driven phototoxic oil. The principal safety constraint is IFRA restriction on rectified birch tar use and PAH marker control rather than phototoxicity.

Contraindications & cautions

majorOnly rectified birch tar oils compliant with IFRA PAH marker limits should be used; recent IFRA certificates cap leave-on body applications (Category 5A) at 0.66%.

THE SCIENCE BEHIND THE SCENT

Inside the oil

5 constituents

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

About this composition

This record describes the rectified smoky birch-tar material sold as white birch essential oil, not sweet birch methyl-salicylate oil. Public quantitative composition was not available as a full GC profile, but recent IFRA conformity documents expose several restricted constituents with exact percentages for rectified birch tar, which are used here as verified anchor constituents.

What we're still learning · 3 data gaps

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

No public full GC profile was located for this rectified white birch tar material; the constituent list is therefore limited to exact restricted constituents disclosed in public IFRA documents.
Odor intensity 85 is a normalized archive inference from supplier language describing strong smoky, charred, tar, leather nuances and overpowering strength, not a directly published 0-100 measurement.
No public source located in this pass gave directly measured volatility-rate or tenacity-hour values.
