Stability

A highly volatile monoterpene, Allo-Ocimene is prone to oxidation when exposed to air and light, potentially forming sensitizing hydroperoxides. Best stored in amber glass at cool temperatures to maintain stability.

Synergies

  • Enhances skin penetration for other lipophilic actives

Conflicts

  • Strong oxidizing agents
  • UV light (catalyzes degradation)
  • High heat (increases volatility and degradation)
