Summary

Antioxidant Antimicrobial Anti-inflammatory Perfuming Skin Conditioning

Science

Mechanism of Action

The extract operates through a dual-action pathway: first, it neutralizes oxidative stress by scavenging free radicals; second, it modulates the inflammatory response by inhibiting the release of arachidonic acid. Its primary constituents, eugenol and cinnamaldehyde, provide targeted antimicrobial activity against acne-causing bacteria, while cinnamyl acetate stimulates microcirculation to enhance nutrient delivery and skin vitality. Furthermore, it supports structural integrity by encouraging collagen synthesis and moisture retention.

Stability

The extract is thermolabile and should be incorporated during the cool-down phase of formulation. It exhibits optimal stability in a pH range of 6.0–8.0, and its chemical integrity can be bolstered by the addition of ascorbic acid as a stabilizer.

Synergies

  • Ascorbic Acid (stabilization)
  • Humectants (enhanced moisture retention)

Conflicts

  • Strong acids (may destabilize pH-sensitive components)

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Moderate

While leaf extract is generally less irritating than bark extract, it contains volatile compounds like eugenol (70-85%) and cinnamaldehyde, which are known contact allergens. Sensitive individuals should perform a patch test, as these compounds can trigger reactions in predisposed skin.
