ABIES LASIOCARPA BRANCH/LEAF OIL.

Optional CAS 2446786-09-8 (generic) / FRAGRANCE

Subalpine fir oil is a pine-scented essential oil rich in monoterpenes like limonene and β-pinene, plus bornyl acetate esters. It delivers moderate antioxidant protection through free radical scavenging while providing natural fragrance benefits. The oil's rubefacient properties stimulate local circulation, though oxidation concerns limit its concentration ranges.

Summary
