Ingredient review
Butylcyclohexanol
INCI: CIS-2-TERT-BUTYLCYCLOHEXANOL
A synthetic cooling agent that creates a refreshing sensation on skin, commonly used in products for a 'cooling' feel without actual temperature change.
In plain English
This ingredient is a man-made compound that tricks your skin's temperature receptors into feeling cool. It doesn't actually lower your skin's temperature—it just feels that way. You'll often find it in lotions, after-sun gels, or foot creams where a refreshing, cooling sensation is desired. It's generally well-tolerated and used at low levels.

Quick decision guide
Useful, but context matters
Butylcyclohexanol 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 Butylcyclohexanol.
- 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
CIS-2-TERT-BUTYLCYCLOHEXANOL is a synthetic organic compound from the cyclohexanol family. It is designed to mimic the cooling effect of menthol but with less intensity and a more subtle, longer-lasting sensation. It is not a natural extract; it is produced through chemical synthesis.
How it works
It activates the TRPM8 receptor (the same receptor that responds to menthol and cool temperatures) on sensory nerve endings in the skin. This triggers a signal to the brain that is interpreted as a cooling sensation, even though no actual heat is removed from the skin. The effect is purely sensory.
Pros
Gentle cooling alternative
Provides a noticeable but mild cooling sensation that is less intense than menthol, making it suitable for facial skincare and sensitive areas.
Good formulation stability
Stable in a wide pH range and compatible with most common cosmetic ingredients, so it won't break down or cause separation in your products.
Cons and cautions
Purely sensory effect
Does not moisturize, treat, or protect the skin—it only creates a temporary cooling feeling. Don't expect any long-term skincare benefits.
Potential for mild irritation
A small percentage of users may experience a slight stinging or tingling, especially if applied to broken or compromised skin.
Best for
- Anyone who enjoys a cooling sensation in skincare, especially after sun exposure or exercise
- People looking for a gentle alternative to menthol in facial or body products
Use caution if
- Those with very sensitive or reactive skin who may find any cooling agent irritating
- Individuals who prefer only natural or plant-derived ingredients
Usage tips
Safety summary
Considered safe for cosmetic use at typical concentrations. Low irritation and sensitization potential based on available safety assessments. Not recommended for use on damaged skin.
Research notes
Research focuses on its sensory effects and safety profile. It is well-documented as a TRPM8 agonist. No long-term human studies on cosmetic benefits beyond sensory modulation.
Common label clues
- Typical concentration
- 0.1% to 1%
- Regulatory status
- Approved for use in cosmetics in the EU, USA, and many other regions. Generally recognized as safe when used at typical cosmetic concentrations.
- Common uses
- Moisturizers, Serums, Sunscreens, After-shave products, Foot care
- Environmental note
- Synthetic production means it does not rely on plant harvesting, but it is derived from petrochemical feedstocks. Biodegradability data is limited.
Good to know
- Often listed near the end of ingredient lists because it's effective at very low concentrations.
- Not the same as menthol—it's a synthetic alternative designed to be milder.
- Commonly found in 'cooling' foot creams, after-sun gels, and lightweight face mists.
