Citronellyl Ethyloxalate
INCI: CITRONELLYL ETHYLOXALATE
Citronellyl Ethyloxalate is a synthetic fragrance ingredient that adds a fresh, citrusy scent but offers no skincare benefits and may cause irritation in sensitive individuals.
In plain English
Citronellyl Ethyloxalate is a man-made chemical used to give products a pleasant, citrus-like smell. It doesn't moisturize, treat, or protect your skin—it's purely there for fragrance.

What it is
Citronellyl Ethyloxalate is a synthetic ester created by combining citronellol (a natural alcohol found in rose and geranium oils) with ethyl oxalate. It is used exclusively as a fragrance ingredient in cosmetics and personal care products.
How it works
In a cosmetic product, Citronellyl Ethyloxalate contributes to the overall scent profile. It evaporates from the skin's surface, releasing a fresh, floral-citrus aroma. It does not have any active skincare function like moisturizing or exfoliating.
Pros
Pleasant scent
Adds a fresh, citrus-floral note that can make the product experience more enjoyable.
Low concentration needed
Only a tiny amount is required to achieve the desired fragrance, so overall exposure is minimal in most products.
Cons and cautions
No skincare benefit
This ingredient does not hydrate, soothe, or protect the skin—it's purely for scent.
Potential irritant
As a fragrance ingredient, it can cause contact dermatitis or allergic reactions in sensitive individuals.
Best for
- Those who enjoy scented products and have no history of fragrance allergies
- People with normal, non-reactive skin
Use caution if
- Individuals with sensitive, reactive, or eczema-prone skin
