Common Name(s): Essential oil,concentrated volatile aromatic,bioactive fragrance active
CAS Number: N/a
DESCRIPTION
What It Does: Provides aromatic sensory benefit alongside bioactive skin activity from concentrated plant volatile compounds — including antimicrobial activity (tea tree, thyme, clove), anti-inflammatory activity (lavender, chamomile), or circulatory stimulation (peppermint, rosemary).
Why It's Used: Essential oils provide authentic 'aromatherapy' narrative with genuine bioactive chemistry — the concentrated terpenoid constituents have documented biological activity in addition to olfactory benefit, justifying ingredient claims beyond pure fragrance.
How It Works: Essential oil complexity: steam distillation concentrates volatile terpenes (monoterpenes, sesquiterpenes), phenylpropanoids, and other volatiles. antimicrobial activity from terpenoid membrane disruption (terpinen-4-ol, eugenol, thymol disrupt bacterial membranes); anti-inflammatory from sesquiterpene nf-kb inhibition; sensitisation risk from electrophilic monoterpene oxides and aldehydes.
