Maltol

About Maltol

Maltol is a synthetic aroma chemical and naturally occurring flavoring molecule with a caramelized, cotton-candy-to-burnt-sugar profile. In perfumery it is used as a sweetener and modifier rather than as a headline note, helping formulas read warmer, rounder, and more edible. In dilute use it can shift toward a fruity strawberry-jam nuance, which is why it often supports gourmand accords instead of standing alone. PubChem describes it as a white crystalline powder with a fragrant caramel-butterscotch odor, while fragrance and flavor references note its role in sweetening and rounding compositions.

Scent Profile

Chemically, maltol is 3-hydroxy-2-methyl-4H-pyran-4-one, CAS 118-71-8. It is widely used in flavors and also appears in fragrance materials, but it is not a botanical extract or a captive trade-name accord. Its effect is usually felt most clearly in traces, where it can increase the impression of cooked sugar, bakery crust, and jammy sweetness without adding obvious spice or smoke.

Use in Perfumery

Maltol can shape a central accord or work as an accent that adds texture and definition. Its exact impression depends on dosage and the surrounding materials.
