What it is
Ethyl Hydroxyheptyl Ketone is a synthetic organic compound classified as a ketone. It is manufactured in a lab and used exclusively as a fragrance ingredient in cosmetics and personal care items.
How it works
In a cosmetic product, Ethyl Hydroxyheptyl Ketone contributes to the overall fragrance profile. It does not have any active skincare function; its sole purpose is to add or modify scent. It evaporates from the skin after application, leaving behind the intended fragrance.
