Ingredient review
Isopentyl Cyclohexyl Acetate
INCI: ISOPENTYL CYCLOHEXYL ACETATE
A synthetic fragrance ingredient that adds a pleasant scent but offers no skincare benefits; generally safe at low concentrations.
In plain English
Isopentyl cyclohexyl acetate is a man-made chemical that smells nice—like a light, floral perfume. It doesn't moisturize, treat, or improve your skin; it's only there to make the product smell good. In tiny amounts, it's considered safe, but if you have sensitive skin or allergies, you might want to avoid fragranced products altogether.

What it is
A synthetic ester compound created by combining isopentyl alcohol with cyclohexyl acetic acid. It is used exclusively as a fragrance ingredient in cosmetics and personal care products.
