Ingredient review
Isopropyl Hydroxycyclohexene Ethanol
INCI: ISOPROPYL-HYDROXYCYCLOHEXENE-ETHANOL
A synthetic cooling agent found in some cosmetics, but with limited safety data and potential for skin irritation.
In plain English
This ingredient is a man-made chemical that adds a cooling or fresh feeling to skincare and beauty products. It is often used in small amounts to create a pleasant sensory experience, like a minty or icy sensation. Because it is a fragrance ingredient, it can sometimes cause irritation, especially for people with sensitive skin. There is not a lot of research on this specific compound, so it is best to approach it with caution if you have reactive skin.

Quick decision guide
Useful, but context matters
Isopropyl Hydroxycyclohexene Ethanol can be useful, but watch for some irritation potential.
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 Isopropyl Hydroxycyclohexene Ethanol.
- 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
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 synthetic organic compound from the cyclohexene family, designed to impart a cooling or refreshing sensation in cosmetic formulations. It is not a natural extract but a lab-created molecule.
How it works
It interacts with temperature-sensitive receptors on the skin, similar to how menthol works, creating a perceived cooling effect without actually lowering skin temperature. This sensory effect is used to enhance the user experience in products like lip balms, lotions, and cleansers.
Pros
Cooling Sensation
Creates a pleasant, refreshing feel on the skin, which can be soothing in warm weather or after exercise.
Low Comedogenic Risk
Unlikely to clog pores, making it suitable for non-acne-prone skin types when used in low concentrations.
Cons and cautions
Limited Safety Data
There is not enough published research on this specific ingredient to fully understand its long-term effects or irritation potential.
Potential Irritant
As a synthetic fragrance component, it may cause redness, stinging, or allergic reactions in sensitive individuals.
Best for
- People who enjoy a cooling sensation in their skincare
- Those without fragrance sensitivities
Use caution if
- Individuals with sensitive or reactive skin
- Anyone with a known fragrance allergy
Usage tips
Safety summary
Considered safe for most people at low concentrations, but the lack of robust safety data and its nature as a fragrance ingredient mean it carries a moderate risk of irritation for sensitive skin.
Research notes
Research on this specific ingredient is sparse. Most safety assessments rely on general knowledge of similar cyclohexene compounds and fragrance ingredients. More studies are needed to confirm its safety profile.
Common label clues
- Typical concentration
- Typically used at very low concentrations, often below 1%
- Regulatory status
- Approved for use in cosmetics in the EU and US, but subject to general fragrance ingredient safety requirements. No specific restrictions are widely noted.
- Common uses
- Fragranced products, Cooling gels, Lip products
- Environmental note
- As a synthetic compound, its environmental persistence and biodegradability are not well-documented. It is typically used in very small amounts.
Good to know
- This ingredient is not a natural essential oil but a synthetic molecule designed for sensory effects.
- It is often used in combination with other cooling agents like menthol to enhance the sensation.
