Isoeugenyl Acetate
INCI: ISOEUGENYL ACETATE
Isoeugenyl Acetate is a synthetic fragrance compound with a warm, spicy scent, but it can be a skin sensitizer for some people.
In plain English
Isoeugenyl Acetate is a man-made chemical that smells like cloves or carnations. It's added to perfumes, lotions, and other scented products to give them a warm, spicy aroma. Because it's a known allergen, it must be listed on the label in the EU and some other regions. For most people it's fine, but if you have sensitive skin or a fragrance allergy, it might cause irritation or redness.

What it is
Isoeugenyl Acetate is an ester derived from isoeugenol, a naturally occurring compound found in essential oils like clove and nutmeg. In cosmetics, it is typically synthesized to ensure purity and consistency.
