Score terms in plain English

Irritation risk

moderate

Can bother some users, especially with frequent use, damaged skin, or strong companion ingredients.

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 from the cyclohexanol family, designed to mimic the cooling effect of natural menthol without the strong minty odor.

How it works

It activates the TRPM8 receptor in the skin, the same receptor that responds to menthol and cool temperatures, creating a temporary cooling sensation without actually lowering skin temperature.

Pros

Instant cooling feel

Provides a noticeable cooling sensation that can make products feel more refreshing, especially after sun exposure or exercise.

Low comedogenic risk

Unlikely to clog pores, making it suitable for oily or acne-prone skin types when used at typical concentrations.

Cons and cautions

Potential skin irritation

At higher concentrations or on sensitive skin, it can cause stinging, redness, or discomfort, similar to menthol.

Fragrance sensitivity

As a synthetic fragrance ingredient, it may trigger allergic reactions or contact dermatitis in fragrance-sensitive individuals.

Best for

  • People looking for a cooling sensation in after-sun or refreshing products
  • Those with normal to oily skin who enjoy sensory skincare

Use caution if

  • Individuals with sensitive, reactive, or eczema-prone skin
  • Anyone with known fragrance allergies

Usage tips

Patch test before using products with this ingredient, especially if you have sensitive skin.
Avoid applying to broken, sunburned, or irritated skin to prevent stinging.

Safety summary

Generally recognized as safe for cosmetic use at typical concentrations, but can cause irritation in sensitive individuals. Regulatory bodies consider it safe when used as directed.

Research notes

Limited peer-reviewed studies specifically on this ingredient; safety is largely extrapolated from related cooling agents and fragrance safety assessments by industry panels.

Common label clues
