Ingredient decoder
INCI name: Eugenol
Scent ingredient that can cause allergic reactions in some people.
Eugenol is the warm, spicy compound that gives clove its scent, added to products for fragrance and also found in cinnamon and bay oils. It is one of the scent components that must be named on EU labels above set levels because it can trigger allergic reactions in some people. For acne-prone skin it does not clog pores, but irritation and redness can make breakouts look and feel worse, so sensitive skin may do better without it.
Not usually, but it is worth watching. Eugenol is not a proven pore-clogger, but scent ingredients like this can irritate sensitive skin, and irritated skin can make breakouts look and feel worse. Notice how your skin reacts when a product lists it near the top.
Clean routine and still breaking out? The cause may be internal. See what is driving it
Eugenol has no published comedogenic rating in Fulton's 1989 table. It is not a proven pore-clogger, but it is worth watching on acne-prone skin.
In short: scent ingredient that can cause allergic reactions in some people. In formulas it is used for denaturant, perfuming and tonic.
On ingredient lists, eugenol can also appear as 4-allyl-2-methoxyphenol.
