Science
Mechanism of Action
The extract operates primarily through its monoterpene alcohol content, specifically linalool, which exerts antimicrobial effects against pathogens like S. aureus. It acts as a mild astringent to refine pore texture and provides antioxidant defense by neutralizing free radicals, thereby preserving the structural integrity of the skin's moisture barrier.
Research
Clinical Evidence
Medium confidence0.04%
Key findings
- 01 Demonstrated significant antioxidant activity (EC50) at a concentration of 15.46 µg/mL through ABTS radical inhibition.
- 02 In vitro cytotoxicity tests on peritoneal macrophages confirmed no cellular toxicity at concentrations as high as 1000 µg/mL.
- 03 Chemical analysis confirms a high-purity profile featuring approximately 93.6% linalool.

Dusting Analysis
Due to its potent aromatic properties and high linalool content, this extract is frequently used at trace levels (below 0.01%) purely for scent masking rather than therapeutic benefit. To achieve its documented antioxidant and antimicrobial effects, it should be formulated near the 0.04% benchmark.
The Formula
Formulation
Stability
Highly prone to oxidation when exposed to atmospheric oxygen. Formulations must be stabilized with 0.1% Vitamin E (alpha-tocopherol) or BHT to prevent the formation of sensitizing hydroperoxides.
Synergies
- Alpha-tocopherol
- BHT
- Glycerin
Conflicts
- Strong oxidizing agents
- High oxygen exposure
- Unstabilized aqueous bases
Safety
Safety Profile
While GRAS designated by the FDA, IFRA standards mandate that peroxide levels remain below 20 mmol/L to mitigate the risk of skin sensitization caused by oxidized linalool.
