Science

Mechanism of Action

Schinus Terebinthifolius Seed Oil primarily functions through its anti-inflammatory effects and broad-spectrum antimicrobial activity against bacteria and fungi. Its antibacterial action involves disrupting bacterial cell walls and membranes, inhibiting enzymes, and depleting proton motive force. Furthermore, it offers antioxidant protection and contains essential fatty acids vital for skin barrier support and nourishment. Traditionally recognized for healing, it also helps to brighten dull or blemish-prone skin.

Stability

The oil's terpenes are prone to oxidation and polymerization over time, which can elevate its skin sensitizing potential. It has also shown solubility challenges in perfume formulations and possesses low bioavailability, necessitating specialized formulation techniques to prolong its active period in cosmetic applications.

Safety

Safety Profile

CIR Status

Sensitization risk Moderate

The neat oil is classified as a Category 1B skin sensitizer. However, a human repeat insult patch test (HRIPT) at 10% concentration did not induce skin irritation or sensitization. Due to its propensity to oxidize over time, its sensitizing potential may increase. Maximum reported use concentrations in consumer products are typically 0.2%, up to 1% in fine fragrances. Beta-caryophyllene, a constituent of the essential oil, is FDA-approved as a flavor enhancer.
