Tonka bean is a fragrance note derived from the seeds of the tonka bean tree (Dipteryx odorata), which primarily grows in South America, particularly in Venezuela. The seeds of this tree are dried and ground to produce tonka bean absolute, a commonly used fragrance in perfumes.

The scent of tonka bean is warm, sweet, and sensual, with vanilla-like and almond-like tones. It also has slightly spicy and woody nuances. Tonka bean is often used as a fixative in perfumes, which means it helps to retain the scent longer and harmonize the various fragrance notes in a fragrance.

Perfumes with tonka bean give a feeling of comfort and warmth. The sweet and creamy scent often has a calming and reassuring effect. Tonka bean can be found in both men's and women's perfumes and is often used in oriental, gourmand, and vanilla fragrances. It adds a certain depth and sensuality to a fragrance and is loved for its pleasant and cozy aroma.
