Ingredient review
Ethylcyclohexene-1-Carboxylate
INCI: ETHYLCYCLOHEXENE-1-CARBOXYLATE
A synthetic fragrance ingredient that adds a pleasant scent but offers no skincare benefits; generally considered safe at low concentrations.
In plain English
Ethylcyclohexene-1-Carboxylate is a man-made chemical used to give cosmetics and skincare products a specific scent. It doesn't moisturize, treat, or improve your skin in any way—it's purely there for fragrance. Because it's used in tiny amounts, it's unlikely to cause problems for most people, but those with very sensitive skin or fragrance allergies may want to avoid it.

What it is
A synthetic ester compound created in a lab, belonging to the family of cyclohexene carboxylates. It is not found naturally and is designed specifically for its aromatic properties.
How it works
In a cosmetic product, it acts as a fragrance ingredient by releasing volatile molecules that interact with olfactory receptors in the nose, creating a perceived scent. It does not interact with the skin's biology or provide any functional skincare benefit.
Pros
Pleasant scent
Provides a consistent, pleasant fragrance that can make your skincare routine more enjoyable.
Low irritation risk
At typical low concentrations, it rarely causes irritation for most users, making it a common choice in perfumery.
Cons and cautions
No skincare benefit
This ingredient adds only scent—it doesn't hydrate, soothe, or protect your skin in any way.
Potential allergen
Like many fragrance ingredients, it can trigger allergic reactions or contact dermatitis in sensitive individuals, especially with repeated use.
Best for
- People who enjoy scented skincare products
- Those without fragrance allergies or sensitivities
