Caramel notes in perfume can be created with accords made from multiple aroma chemicals, both synthetic and natural. The aroma chemical maltol is a powder that smells like cotton candy with a sweet, sugary, caramel scent; it is found naturally in cocoa, strawberries, coffee, malt, and some pine bark. Another example of an aroma chemical with a caramel note is the extremely potent caramel furanone, which has a sweet, caramelic, nutty, roasted scent. Many ingredients with a caramel note must be used judiciously because they can be quite strong.
