trans-2-tert-Butylcyclohexanol

INCI: trans-2-tert-Butylcyclohexanol

A synthetic cooling ingredient that creates a refreshing, minty sensation on skin without the strong scent of menthol, but may cause mild irritation in sensitive individuals.

In plain English

This is a lab-made ingredient that tricks your skin into feeling cool, similar to menthol but without the strong minty smell. It doesn't actually lower your skin temperature—it just feels that way. You'll often find it in products meant to refresh or soothe, like after-sun lotions, eye creams, or foot creams. It's generally well-tolerated, but people with very sensitive skin might notice a slight tingling or irritation.

Quick decision guide

Useful, but context matters

trans-2-tert-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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging trans-2-tert-Butylcyclohexanol.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

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

A synthetic organic compound derived from cyclohexanol, designed to mimic the cooling sensation of menthol but with a milder, less pungent profile. It is a clear, colorless liquid at room temperature and is used in very small amounts in cosmetic formulations.

How it works

It activates the TRPM8 receptor (the same cold-sensing receptor that menthol triggers) on sensory nerve endings in the skin. This sends a signal to the brain that feels like a cooling sensation, even though no actual temperature change occurs. In a product, it provides an immediate, noticeable 'fresh' feel that can make the skin feel invigorated or soothed.

Pros

Pleasant cooling without strong scent

Unlike menthol, this ingredient provides a cooling sensation without a strong minty or medicinal smell, making it more versatile for unscented or lightly fragranced products.

Enhances product feel

It adds a noticeable 'fresh' or 'invigorating' feel to creams, serums, and lotions, which can make the routine feel more luxurious and soothing, especially in warm weather.

Cons and cautions

Potential for mild irritation

In some people, especially those with sensitive or compromised skin, it can cause a temporary stinging or tingling sensation that may be uncomfortable.

Purely sensory effect

The cooling is only a perception—it does not actually cool the skin or provide any therapeutic temperature reduction, so it won't help with heat-related skin issues.

Best for

  • People who enjoy a refreshing, cooling feel in their skincare
  • Those looking for a non-minty cooling option for after-sun or foot care

Use caution if

  • Individuals with very sensitive, reactive, or damaged skin

Usage tips

Start with a product that contains this ingredient at a low concentration if you have sensitive skin.
Apply after cleansing and before heavier creams to let the cooling sensation be most noticeable.
Avoid applying to broken, sunburned, or irritated skin to prevent stinging.

Safety summary

Generally recognized as safe for cosmetic use at typical concentrations. Some individuals may experience mild, temporary skin irritation or stinging. It is not considered a common allergen or sensitizer. Always patch test if you have sensitive skin.

Research notes

Research on trans-2-tert-Butylcyclohexanol focuses on its sensory effects as a TRPM8 agonist. Studies confirm it produces a cooling sensation similar to menthol but with lower volatility and odor. Safety assessments by cosmetic ingredient review panels have found it safe for topical use at low concentrations.

Common label clues

Typical concentration
0.1% to 1%
Regulatory status
Approved for use in cosmetics in the EU, US, and many other regions. It is not a restricted ingredient, but formulators must follow safe concentration guidelines (typically under 1%).
Common uses
Moisturizers, Serums, Eye creams, Foot creams, After-sun products
Environmental note
As a synthetic compound, it is produced through chemical synthesis. There is limited public data on its biodegradability or environmental persistence, but it is used in very low concentrations in rinse-off and leave-on products.

Good to know

  • This ingredient is often listed near the end of an ingredient list because it's used in very small amounts.
  • It is not the same as menthol—it's a synthetic alternative designed to be less pungent.
  • The cooling effect typically lasts 15–30 minutes after application.
