What it is
A synthetic ester formed from cis-3-hexenol (a natural compound found in green leaves) and valeric acid. It is used exclusively as a fragrance ingredient in cosmetics and personal care products.
How it works
It evaporates from the skin after application, releasing a green, leafy aroma. It does not interact with the skin's biology or provide any functional benefit beyond scent.
Pros
Pleasant green scent
Adds a fresh, natural leafy aroma that many find appealing and less cloying than floral or sweet fragrances.
Low irritation potential
At typical use levels, it is considered a low irritant and is widely accepted in fragrance formulations.
Cons and cautions
No skin benefit
This ingredient is purely for scent and does not hydrate, soothe, or improve skin health in any way.
Potential allergen
Like all fragrance ingredients, it can cause allergic reactions in sensitive individuals, especially with prolonged use.
Best for
- Anyone who enjoys fresh, green fragrances in their skincare
- Those looking for a non-floral, natural-smelling scent
Use caution if
- Individuals with known fragrance allergies or very sensitive skin who prefer fragrance-free products
