Science
Mechanism of Action
This ingredient operates as a lipophilic delivery vehicle for green tea catechins, specifically EGCG. Through enzymatic transesterification, the polyphenols are grafted onto a triglyceride carrier, allowing them to traverse the lipid-rich stratum corneum more effectively than traditional extracts. Once integrated into the skin, it provides dual-action benefits: the ester base reinforces the moisture barrier while the released antioxidants neutralize oxidative stress at a cellular level.
Research
Clinical Evidence
High confidence2%
Key findings
- 01 Concentrations of 1-5% significantly enhance the bioavailability and radical scavenging capacity of green tea polyphenols compared to standard water-soluble versions.
- 02 In vivo testing at 2% demonstrated a measurable reduction in oxidative stress markers and a significant decrease in transepidermal water loss (TEWL) for improved barrier integrity.
Transparency
Dusting Analysis
While often used at lower levels as a 'label claim' botanical, true physiological benefits for barrier repair and antioxidant bioavailability require inclusion rates of at least 1-2%.
The Formula
Formulation
Stability
Produced via low-heat enzymatic catalysis, making it highly stable; however, it remains susceptible to hydrolysis in extreme pH environments (below 3 or above 9).
Synergies
- Tocopherol
- Squalane
- Ceramides
Conflicts
- Strong oxidizing agents
- Highly alkaline formulations
- Highly acidic peels
Safety
Safety Profile
Its constituent parts, Caprylic/Capric Triglyceride and Green Tea Extract, are both widely recognized as safe for cosmetic use by the CIR.
