How is it used?

Isoeugenol is a fragrance chemical used in cosmetic* and household products. Often called only fragrance on ingredients list, it can be found in formulations for products such as shampoo, makeup, soaps, detergents and oral products.

Isoeugenol is also used as a flavoring agent (substances added to improve the taste in foods and medicine). The substance is for example been used in the production of vanillin. Vanillin is the synthetic version of natural vanilla. Nowadays it is more common to find synthetic vanillin than natural vanilla in consumer products like beverages, pharmaceuticals and foods.
