In short
Tuberolide, sold by Givaudan as methyl tuberate, is a gamma-lactone with a lactonic, floral tuberose character. It is used as a modifier in floral accords.
What Tuberolide smells like
The Good Scents Company quotes Givaudan's description of methyl tuberate as lactonic and floral with a tuberose character, used as a modifier in floral accords, and its own panel's waxy, lactonic, coconut, floral, plum and winey. Fraterworks describes white floral with metallic edges and subtle plum-like fruit.

What makes Tuberolide distinctive
The lactone of tuberose, rather than of peach or coconut.
How Tuberolide is used
Givaudan, as The Good Scents Company quotes it, uses methyl tuberate as a modifier in floral accords.
Typical role: modifier (used in small amounts to change the character of a blend).
How Tuberolide differs from similar materials
- Jessemal
- Jessemal is a creamy jasmine with a lactonic smoothness; Tuberolide is lactonic itself, coconut and waxy with plum, the note of tuberose rather than jasmine.
- Tuberose Absolute
- Tuberose absolute is cream with a cool, wintergreen-green sharpness; Tuberolide is its lactone note alone, coconut-waxy with plum.
Each difference compares the published descriptions of the two materials. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
