Ingredient review
Ethyl Isopropyl Bicycloheptene Carboxylate
INCI: ETHYL ISOPROPYL-BICYCLOHEPTENE-2-CARBOXYLATE
A synthetic fragrance ingredient that adds scent to products; generally considered safe at low levels but may cause sensitivity in some individuals.
In plain English
This is a man-made chemical added to skincare and beauty products to give them a specific smell. It doesn't do anything for your skin's health or appearance—it's purely for fragrance. Because it's used in tiny amounts, it's usually not irritating, but people with very sensitive skin or fragrance allergies might want to avoid it.

What it is
A synthetic ester compound specifically designed to provide a pleasant fragrance in cosmetic formulations. It belongs to a class of ingredients known as fragrance allergens, though it is not among the most common sensitizers.
How it works
It evaporates from the skin's surface, releasing scent molecules that are detected by the nose. In a product, it simply contributes to the overall fragrance profile and has no functional skincare benefit.
Pros

Adds a nice smell to products, making the application more enjoyable for many users.
Low irritation potential
At typical low concentrations, it rarely causes irritation for most people.
Cons and cautions
No skin benefit
This ingredient does not moisturize, protect, or improve skin health—it only adds fragrance.
Potential allergen
Like many fragrance ingredients, it can trigger allergic reactions or irritation in sensitive individuals.
Best for
- People who enjoy scented skincare and have no history of fragrance allergies
- Those looking for a pleasant sensory experience in their routine
Use caution if
- Individuals with known fragrance allergies or sensitive, reactive skin
