CALLITRIS INTRATROPICA WOOD OIL.

Valuable CAS 180287-43-8 / FRAGRANCE

A rare, cobalt-blue botanical oil steam-distilled from the heartwood of the Australian Northern Territory Cypress. It serves as a potent remedial agent, combining sesquiterpene-rich anti-inflammatory properties with exceptional antioxidant capacity to stabilize reactive skin environments.

Summary

Soothing Antioxidant Anti-inflammatory Astringent Natural Fragrance

Science

Mechanism of Action

The oil's efficacy is driven by its high sesquiterpene content, specifically guaiazulene and chamazulene, which inhibit inflammatory pathways and provide its characteristic blue hue. These compounds, alongside guaiol and eudesmols, offer antimicrobial support and mild astringency to refine pore texture, while its high radical-scavenging activity (measured at 78.6% in ABTS assays) neutralizes oxidative stress.

Key findings

  1. 01 Ranked as the second highest antioxidant among eleven Australian essential oils tested via ABTS radical-scavenging assays.
  2. 02 Demonstrated significant dose-dependent protection and anti-erythema effects at concentrations between 0.1% and 1.0%.
  3. 03 High-concentration studies (5%–20%) confirm significant biological activity, specifically in insect repellency, compared to synthetic controls.

Due to its intense blue color and high cost, this ingredient is frequently used at trace levels (<0.05%) merely to tint a formula or for marketing 'label claims' rather than for its therapeutic anti-inflammatory or antioxidant benefits.

Stability

Highly sensitive to photo-oxidation and thermal degradation; exposure to light or temperatures exceeding 30°C will cause the vibrant blue color to fade and reduce its antioxidant potency.

Synergies

  • Bisabolol (enhanced soothing)
  • Tocopherol (oxidative stability)
  • Squalane (improved dermal delivery)

Conflicts

  • Strong oxidizing agents
  • PVC materials
  • High-heat processing
