Ingredient review
Ethyl Tetramethylcyclohex-2-enecarboxylate
INCI: ETHYL TETRAMETHYLCYCLOHEX-2-ENECARBOXYLATE
A synthetic fragrance ingredient that adds scent but offers no skincare benefits; generally safe at low levels but may cause irritation in sensitive individuals.
In plain English
This is a man-made chemical used to give products a pleasant smell. It doesn't moisturize, treat, or improve your skin in any way—it's purely there for the sensory experience. Because it's a fragrance ingredient, it can sometimes cause irritation or allergic reactions, especially if you have sensitive skin.

What it is
A synthetic ester compound used exclusively as a fragrance ingredient in cosmetics and personal care products. It is not a natural extract but is created in a lab to provide a specific scent profile.
How it works
It evaporates from the skin after application, releasing scent molecules that are detected by your nose. It does not interact with the skin's biology or provide any functional benefit beyond fragrance.
Pros
Pleasant scent
Adds a subtle, pleasant fragrance that can make your skincare routine more enjoyable.
Low irritation potential at low levels
When used at very low concentrations, it is generally well-tolerated by most skin types.
Cons and cautions
No skincare benefit
This ingredient does nothing for your skin—no hydration, anti-aging, or protection. It's purely for scent.
Potential allergen
As a synthetic fragrance, it can cause contact dermatitis or allergic reactions in people with fragrance sensitivities.
Best for
- People who enjoy scented skincare and have no history of fragrance allergies
- Those looking for a subtle, non-overpowering scent in their products
Use caution if
- Individuals with sensitive, reactive, or eczema-prone skin
- Anyone with a known allergy or sensitivity to synthetic fragrances
