Common Name(s): Linalool epoxide,furanoid linalool oxide
CAS Number: 1365-19-1
DESCRIPTION
What It Does: Provides linalool oxide floral fragrance with mild anti-inflammatory activity.
Why It's Used: Linalool metabolite fragrance — linalool oxide provides the oxidised form of linalool's floral fragrance with distinct olfactory character and potential sensitisation requiring eu allergen labelling.
How It Works: Oxidation product of linalool in essential oils (especially aged oils exposed to air). mild anti-inflammatory from ether structure. different fragrance note from linalool — more earthy, camphoraceous. eu declared allergen requiring labelling.

SCIENTIFIC NOTE
Linalool oxide's formation in aged essential oils illustrates autoxidation: linalool's allylic double bond reacts with atmospheric oxygen forming the linalool-2,3-oxide and 5,6-oxide. this aging/oxidation-generated sensitiser explains why old or improperly stored lavender oil can become more allergenic than fresh oil — fragrance allergen content increases with improper storage conditions.
