Ingredient review
Butyl Butyrate
INCI: Butyl Butyrate
Butyl Butyrate is a synthetic ester that adds a fruity, sweet scent to products, but it offers no direct skin benefit and may cause irritation in sensitive individuals.
In plain English
Butyl Butyrate is a man-made chemical that smells fruity, like pineapple or apple. It's added to lotions, creams, and perfumes to make them smell nice. It doesn't moisturize or treat your skin—it's purely for scent. While generally safe, people with very sensitive skin or fragrance allergies might want to avoid it.

What it is
Butyl Butyrate is a synthetic ester formed from butyl alcohol and butyric acid. It is a clear, colorless liquid with a strong fruity odor, commonly used as a fragrance ingredient in cosmetics.
How it works
In a cosmetic product, Butyl Butyrate functions solely as a fragrance ingredient. It evaporates from the skin's surface, releasing its scent. It does not have any active skin-care benefits like moisturizing, exfoliating, or protecting.

Low irritation potential for most

Potential allergen
Like many fragrance ingredients, it can cause allergic reactions or irritation in people with sensitive skin or fragrance sensitivities.
