Science
Mechanism of Action
The primary active component of Cajuput Leaf Oil is cineole (1,8-cineole). Topically, cineole can act as a mild counter-irritant, generating a warming sensation that may contribute to underlying pain relief. Beyond this, it demonstrates broad-spectrum activity, providing antiseptic, anti-inflammatory, and antibacterial effects against various gram-positive and gram-negative bacteria, yeasts, molds, and even demodex mites.

Key findings
- 01 Exerted significant antibacterial activity against key pathogens including Staphylococcus aureus, Streptococcus pyogenes, methicillin-resistant Staphylococcus aureus (MRSA), Klebsiella pneumoniae, and Escherichia coli.
- 02 In a facial serum formulation, these concentrations demonstrated bactericidal effects, reducing Cutibacterium acnes by over 3 log10 CFU/mL within 8 hours of treatment.
- 03 Also within a facial serum, this concentration shortened the killing time against Cutibacterium acnes and exhibited notably high antioxidant and immunomodulatory activity.

Dusting Analysis
The research indicates specific effective concentrations ranging from 0.714% to 4% for various antimicrobial actions. Formulations utilizing concentrations below this empirically supported range may not deliver the full intended benefits.
The Formula
Formulation
Stability
Cajuput oil, like most essential oils, is composed of volatile compounds. While no precise optimal pH range for stability is documented, it is generally considered stable and non-reactive under standard storage and transportation conditions.
Conflicts
- strong oxidizing agents
- direct, undiluted application to skin
Safety
Safety Profile
Cajuput oil is generally regarded as 'POSSIBLY SAFE' for topical application to unbroken skin when adequately diluted. However, it can induce allergic reactions and is identified as an irritant to both skin and eyes, as well as a dermal and respiratory sensitizer. Inhalation is 'LIKELY UNSAFE,' especially for children, due to the risk of severe breathing issues. The FDA does not regulate the purity or quality of essential oils.
