Catalog › Smoky › Birch tar oil rectified
Smoky, phenolic, charred-wood tar note that is the historical soul of 'cuir de Russie' - burning campfire, smoked leather and creosote with a sweet balsamic underlay. Only rectified qualities are usable and IFRA-restricted; traces suffice for potent leather-smoke effects.
An estimated breakdown, not a certificate of analysis, and it is what PerfuMate sums when it checks a formula: a molecule arriving from three naturals at once is counted once rather than missed three times. Paste your own supplier analysis and it takes over.

Restricted under IFRA. This material carries a restriction. PerfuMate checks your formula against the current standard as you build, including the same molecule arriving from several naturals at once.
PerfuMate's own reference accords, published to its community, that reach for this material. The figure is its share of the concentrate.
Read from the published accords rather than asserted: these materials appear beside Birch tar oil rectified in at least two of the reference accords published to the PerfuMate community.
Ranked by how many olfactive sub-categories they share with Birch tar oil rectified, not alphabetically.
What this page carries, beside what the whole catalog carries. Every figure on the right is counted from the file the app ships, at the moment this page was built, so it cannot drift from the product the way a sentence somebody typed would.
And the limits, because they decide how far the rest can be trusted. Every regulatory join - IFRA, GHS, allergens - is by CAS number, and a material can supply one through its constituents as well as its own row, so of the 428 materials carrying no CAS number the 127 without a constituent table are the ones that return "nothing known" rather than "nothing applies". The blotter hours are sourced rather than measured by us, and the app labels every one of them an estimate. There is no physical chemistry on a row: no molecular weight, no vapour pressure, no boiling point. The longer answer, or the whole catalog counted.
