Dupical

What Dupical smells like

Dupical (Givaudan) is a powerful, fresh, transparent aldehydic muguet, which Givaudan presents as a modifier and enhancer of lily-of-the-valley character. Fraterworks describes a fresh, green, slightly watery lily-of-the-valley quality with a light marine-aldehydic undertone and no heavy indolic side; The Good Scents Company lists floral, sweet, muguet, aldehydic and waxy. It is very potent — a trace is very noticeable, and overdosing flattens the materials around it.

What makes Dupical distinctive

It is an enhancer rather than a muguet on its own: used in traces to make a lily-of-the-valley accord brighter and more transparent.

Concentration and dilution

Very potent; evaluated at 1% or less.

How Dupical is used

Used in traces as a modifier and enhancer of muguet character in floral compositions.

Typical role: modifier (used in small amounts to change the character of a blend).

How Dupical differs from similar materials

Bourgeonal

Bourgeonal is more watery and metallic, with a woody drydown; Dupical is a transparent aldehydic enhancer.

Nympheal

Nympheal is opulent and diffusive, with linden and cyclamen; Dupical is more transparent and aldehydic.

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.

Formulation considerations

Very potent; dose from dilution.
