A synthetic fragrance ingredient that adds a pleasant floral scent but offers no skincare benefits and may be unnecessary for sensitive skin.
In plain English

What it is
P-Cresyl Propionate is a synthetic ester derived from p-cresol and propionic acid. It is used as a fragrance ingredient in cosmetics and personal care products to impart a floral, sweet, or honey-like scent.
How it works
In a cosmetic product, P-Cresyl Propionate evaporates from the skin, releasing its scent molecules into the air. It does not interact with the skin's biology or provide any functional benefit beyond fragrance.

Low irritation risk for most

Best for
