Ingredient review
Ethyl Menthane Carboxamide
INCI: Ethyl Menthane Carboxamide
A synthetic cooling compound that delivers a refreshing, long-lasting chill without menthol's strong odor or volatility.
In plain English
Ethyl Menthane Carboxamide is a lab-made ingredient that tricks your skin into feeling cool. Unlike menthol (which evaporates quickly and can smell like peppermint), this molecule binds to the same cold-sensing receptors on your skin cells and keeps them activated for a longer period. The result is a gentle, steady cooling sensation that can last for hours, making it popular in products meant to soothe, refresh, or reduce the feeling of heat.

Quick decision guide
Useful, but context matters
Ethyl Menthane Carboxamide 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 Ethyl Menthane Carboxamide.
- 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
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A synthetic amide derivative of menthol, designed to provide a cooling sensation without the strong minty odor or high volatility of natural menthol.
How it works
It activates the TRPM8 receptor (a cold-sensing ion channel) on sensory nerve endings in the skin. This triggers a signal to the brain that mimics the sensation of cooling, even though no actual temperature change occurs. Because it doesn't evaporate like menthol, the effect lasts longer.
Pros
Long-lasting cooling
The cooling effect can persist for hours, unlike menthol which fades quickly, making it ideal for products intended to provide sustained refreshment.
Odorless and non-volatile
It has no strong minty smell and doesn't evaporate rapidly, so it won't clash with other fragrances or cause eye irritation from fumes.
Cons and cautions
Sensory-only benefit
It doesn't moisturize, treat, or change skin health — the cooling is purely a sensory trick, so it shouldn't be relied on for therapeutic effects.
Potential tingling in sensitive skin
Some users may experience a prickly or overly intense cold sensation, especially at higher concentrations or on broken skin.
Best for
- Anyone who enjoys a refreshing, cooling feel in skincare or body care
- People looking for a non-minty cooling option for after-sun or post-workout products
Use caution if
- Individuals with very sensitive skin or a history of reactions to cooling agents
Usage tips
Safety summary
Generally recognized as safe for topical cosmetic use at typical concentrations (0.1–1%). Mild skin irritation is rare but possible in sensitive individuals. Avoid contact with eyes and mucous membranes.
Research notes
Human sensory studies confirm its ability to activate TRPM8 receptors and produce a cooling sensation lasting several hours. No significant safety concerns have been raised in cosmetic ingredient reviews.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Approved for cosmetic use in the EU, USA, and many other regions. It is not a drug ingredient and is regulated as a cosmetic sensory additive.
- Common uses
- Moisturizers, Serums, Eye creams, Foot creams, Lip balms, After-sun products
- Environmental note
- Synthetically produced, so it does not rely on natural menthol harvesting. Its environmental impact is considered low at typical use levels.
Good to know
- Ethyl Menthane Carboxamide is often listed under the trade name WS-3.
- It is stable in most formulations and works well in both water-based and oil-based products.
- The cooling effect is dose-dependent — higher concentrations feel more intense.
