What It Does
Betula Alba (Birch) Bark Oil (rectified) is the redistilled essential oil/tar oil obtained from the bark of white birch (Betula alba). The crude product is birch tar, and rectification (redistillation) removes heavier PAH fractions, yielding a cleaner product suitable for fragrance use. It is well-known in perfumery for imparting smoky, leathery, tar-like notes (classic 'Russian leather' accord). The INCI name in CosIng is BETULA ALBA BARK OIL. The parenthetical '(rectified)' is a processing qualifier rather than part of the formal INCI but is important for regulatory and quality purposes. CAS 8001-88-5 is commonly assigned to birch tar oil. Confidence is slightly below 1.0 because the exact CAS can vary between sources (some assign different CAS numbers to crude vs. rectified grades), and INCI naming conventions for Betula species have evolved (Betula alba vs. Betula pendula).
