What it is
A synthetic ester derived from furylpropionic acid and isobutyl alcohol, used exclusively as a fragrance ingredient in cosmetics and personal care products.
How it works
It evaporates from the skin's surface, releasing a pleasant fruity aroma that masks the natural scent of other ingredients. It does not interact with skin cells or provide any functional benefit beyond fragrance.

Low irritation risk for most
At typical low concentrations, it is unlikely to cause problems for people without fragrance sensitivities.

This ingredient only provides fragrance and does not hydrate, protect, or improve skin health.
Potential allergen
Like many fragrance ingredients, it can trigger allergic reactions or irritation in sensitive individuals, especially with repeated use.
Best for
- People who enjoy scented skincare and have no history of fragrance allergies
- Those using products where scent is a priority
Use caution if
- Individuals with sensitive, reactive, or eczema-prone skin
