Ethyl Tricyclodecanecarboxylate
INCI: ETHYL TRICYCLODECANECARBOXYLATE
A synthetic fragrance ingredient that provides a fresh, woody scent but offers no direct skincare benefits.
In plain English
Ethyl Tricyclodecanecarboxylate is a man-made chemical added to products to give them a pleasant, fresh, woody smell. It doesn't moisturize, exfoliate, or treat skin concerns—it's purely for scent. While generally considered safe at low levels, it can be a potential irritant for those with sensitive skin or fragrance allergies.

What it is
A synthetic ester compound used as a fragrance ingredient in cosmetics and personal care products. It is not derived from natural sources but is created in a lab to produce a specific scent profile.
How it works
It works by evaporating from the skin's surface, releasing molecules that interact with olfactory receptors in the nose to create the perception of a fresh, woody scent. It has no active effect on the skin itself.
Pros

Provides a fresh, woody aroma that can make your skincare routine more enjoyable.
Low irritation for most
At typical low concentrations, it is generally well-tolerated by people without fragrance sensitivities.
Cons and cautions
No skincare benefit
This ingredient does not hydrate, repair, or protect the skin—it only adds fragrance.
Potential allergen
Like many synthetic fragrances, it can cause contact dermatitis or allergic reactions in sensitive individuals.
Best for

- People without fragrance sensitivities or allergies
Use caution if
