Palmitoyl Green Tea Extract

INCI: PALMITOYL CAMELLIA SINENSIS EXTRACT

A stabilized, oil-friendly version of green tea extract that brings antioxidant and soothing power to formulas without the instability of plain green tea.

beautyskincareantioxidant

In plain English

This is green tea extract that has been chemically linked to a fatty acid (palmitic acid) so it mixes better with oils and stays active longer in skincare products. It helps protect skin from environmental damage and calms irritation, much like regular green tea, but it's more shelf-stable and can penetrate deeper into the skin.

Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

Score terms in plain English

Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

Palmitoyl Camellia Sinensis Extract is green tea (Camellia sinensis) extract that has been reacted with palmitic acid, a common fatty acid. This creates a more lipophilic (oil-loving) molecule that is less likely to degrade and can be incorporated into oil-based and emulsion formulas more easily.

How it works

Once applied, the palmitoyl group helps the green tea polyphenols (especially EGCG) absorb into the outer layers of skin. There, the antioxidants neutralize free radicals from UV and pollution, while the catechins help reduce inflammation and soothe redness. The palmitic acid part also contributes mild moisturizing properties.

Pros

Enhanced stability

The palmitoyl modification prevents the green tea polyphenols from oxidizing quickly, so the ingredient stays effective longer on the shelf and in the bottle.

Better oil compatibility

Unlike plain green tea extract, this version blends easily into creams, serums, and oil-based products, giving formulators more flexibility.

Cons and cautions

Potentially reduced potency

The chemical modification may slightly lower the antioxidant activity compared to fresh, unmodified green tea extract, though it remains effective.

Less research

Most studies on green tea's skin benefits use the unmodified extract. There is less published research specifically on the palmitoyl version, so its exact efficacy is less documented.

Best for

Anyone looking for antioxidant protection in a stable, oil-friendly form
People with sensitive or easily irritated skin who want a soothing ingredient

Use caution if

Those with a known allergy to green tea or palmitic acid (rare)

Usage tips

Look for this ingredient in the middle to upper half of the ingredient list for meaningful antioxidant levels.

Store products containing this ingredient in a cool, dark place to preserve its activity, even though it is more stable than plain green tea.

Safety summary

Palmitoyl Camellia Sinensis Extract is considered safe for topical use. The palmitoyl modification is a common cosmetic chemistry technique and does not introduce known toxicity. Patch testing is recommended for those with very sensitive skin or green tea allergies.

Research notes

Green tea extract has strong evidence for antioxidant and anti-inflammatory effects on skin. The palmitoyl version is less studied directly, but its mechanism is well understood and supported by the broader research on green tea polyphenols and fatty acid conjugation.

Common label clues

Typical concentration: 0.1% to 2%
Regulatory status: Generally recognized as safe for cosmetic use in the EU, US, and other major markets. No specific restrictions beyond general cosmetic ingredient safety.
Common uses: Anti-aging serums, Moisturizers, Eye creams
Environmental note: Palmitic acid is often derived from palm oil, which can have environmental impacts related to deforestation. Look for brands that use sustainably sourced or certified palm derivatives.

Good to know

Palmitic acid is a common fatty acid found in palm oil and animal fats, so sourcing may be a concern for some users.
This ingredient is often used in anti-aging and soothing products because it combines antioxidant and calming benefits.
