Science
Mechanism of Action
It functions by integrating high-purity fatty acids—specifically oleic (approx. 80%), linoleic, and palmitic acids—directly into the stratum corneum. As an ethyl ester, it features a lower molecular weight than the raw oil, allowing for superior spreadability and the creation of a breathable, semi-occlusive film that prevents transepidermal water loss (TEWL) and shields skin from pollutants.

Key findings
- 01 Clinical testing by the KC Skin Clinical Research Center (2021) demonstrated that formulations containing this ester significantly improved transdermal moisture retention within 60 minutes and maintained hydration for 24 hours.
- 02 In vivo studies on the parent Camellia japonica oil indicate its ability to stimulate Type I procollagen production and drastically reduce barrier permeability within 1–2 hours of application.

Dusting Analysis
Because this is often used as a primary solvent or emollient base in 'dry oils' or mists, it is rarely 'dusted.' However, in complex emulsions, levels below 1% may be insufficient to provide the 24-hour hydration benefits observed in clinical settings.
The Formula
Formulation
Stability
Significantly more resistant to oxidation than traditional triglyceride oils. It remains stable unless exposed to extreme pH levels (below 3 or above 8), which can trigger hydrolysis into ethanol and fatty acids.
