Ingredient review
Amyl Isovalerate
INCI: AMYL ISOVALERATE
Amyl Isovalerate is a synthetic fragrance ester that adds a fruity, apple-like scent to products, but offers no skincare benefits and may cause sensitivity in some individuals.
In plain English
Amyl Isovalerate is a man-made ingredient that smells fruity, like apples or pineapple. It's added to lotions, creams, and perfumes just for the scent. It doesn't moisturize, treat, or improve your skin in any way.

What it is
Amyl Isovalerate is a synthetic ester created by combining amyl alcohol and isovaleric acid. It is a clear, colorless liquid with a strong fruity, apple-like odor. In cosmetics, it functions solely as a fragrance ingredient.
How it works
Amyl Isovalerate works by evaporating from the skin or hair, releasing its fruity scent molecules into the air. It does not interact with the skin's biology or provide any functional benefit beyond fragrance.
Pros
Pleasant fruity scent
Adds a natural-smelling apple or pineapple note that many people find enjoyable in lotions and perfumes.
Low irritation for most
At typical low concentrations, it is well-tolerated by the majority of users without causing redness or breakouts.
Cons and cautions
No skincare benefit
This ingredient is purely for scent; it does not moisturize, soothe, or improve skin health in any way.
Potential allergen
As a fragrance ingredient, it can trigger contact dermatitis or allergic reactions in people with fragrance sensitivities.
Best for
- People who enjoy lightly fragranced products and have no known fragrance allergies
