Ingredient review
Octanicotinoyl Epigallocatechin Gallate
INCI: Octanicotinoyl Epigallocatechin Gallate
A next-generation green tea antioxidant that's more stable and penetrates skin better than plain EGCG, but research is still early.
In plain English
This is a lab-enhanced version of EGCG, the powerful antioxidant found in green tea. By attaching a fatty acid-like molecule (octanicotinoyl), scientists made it more stable in formulas and better at getting into skin. Once inside, it works like a shield against free radicals from UV and pollution, and may help calm redness and support collagen. Because it's newer, most evidence comes from lab studies rather than large human trials.

Quick decision guide
Useful, but context matters
Octanicotinoyl Epigallocatechin Gallate is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Octanicotinoyl Epigallocatechin Gallate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A semi-synthetic derivative of epigallocatechin gallate (EGCG), the main antioxidant in green tea. The octanicotinoyl group is added to improve stability and oil solubility, making it easier to formulate into creams and serums.
How it works
It donates electrons to neutralize free radicals before they can damage skin cells. The modified structure allows it to penetrate the stratum corneum (the outer skin layer) more effectively than plain EGCG. It also may inhibit enzymes that break down collagen and elastin, helping preserve skin firmness.
Pros
Better stability than plain EGCG
The octanicotinoyl modification prevents rapid oxidation, so the ingredient remains active longer in the bottle and on the skin.
Enhanced skin penetration
The fatty chain helps the molecule slip through the skin's lipid barrier, delivering antioxidant power deeper than water-soluble EGCG.
Cons and cautions
Limited human research
Most studies are lab-based or small-scale. Larger, long-term human trials are needed to confirm anti-aging benefits compared to established antioxidants.
Premium price point
Because it's a specialized derivative, products containing it tend to cost more, which may not fit every budget.
Best for
- Anyone looking for a stable, potent antioxidant that works well in oil-based or emulsion formulas
- People with normal to dry skin who want anti-aging protection without irritation
Use caution if
- Those with very sensitive skin should patch-test first, as even low-irritation ingredients can cause reactions in rare cases
Usage tips
Safety summary
Considered safe for topical use at typical concentrations. Low irritation and comedogenic risk based on available data. As with any new ingredient, patch-testing is recommended for sensitive individuals.
Research notes
Preclinical studies show strong antioxidant activity and improved skin penetration compared to EGCG. Human studies are limited but promising for anti-aging and photoprotection. More clinical trials are needed to confirm long-term efficacy.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Approved for cosmetic use in most regions including the EU, US, and Asia. Not classified as a drug ingredient.
- Common uses
- Anti-aging serums, Brightening treatments, Protective day creams
- Environmental note
- Synthesized in a lab, so it does not require agricultural land or water like plant extracts. Biodegradability data is not yet publicly available.
Good to know
- This ingredient is often listed near the middle or end of an INCI list because effective concentrations are low.
- It is not the same as plain green tea extract — it's a modified molecule with different properties.
