What it is
P-Anisyl Butyrate is an ester compound synthesized from anisyl alcohol and butyric acid. It is a colorless to pale yellow liquid with a sweet, floral, and slightly fruity odor, commonly used in perfumery and cosmetic fragrances.
How it works
In a cosmetic product, P-Anisyl Butyrate acts solely as a fragrance ingredient. It evaporates from the skin or hair, releasing its scent. It does not provide any moisturizing, anti-aging, or other skincare benefits.

Low irritation risk for most
At typical low concentrations, it is generally non-irritating for the majority of users.
Cons and cautions
No skincare benefit

Potential allergen
As a fragrance ingredient, it can cause contact dermatitis or allergic reactions in sensitive individuals.
Best for
