In short
Florhydral is a trade name for 3-(3-isopropylphenyl)butanal, an aromatic aldehyde with a powerful, fresh green-muguet odour. It brings a watery, dewy freshness to floral accords.
What Florhydral smells like
Florhydral (Givaudan) is a powerful, fresh, green muguet aldehyde. Givaudan's description is floral, green, muguet, fresh and powerful, with a natural-smelling lily-of-the-valley and hyacinth character. Other sources add a watery-green freshness and a light cucumber-melon facet. Its two mirror-image forms differ: one green and powerful, the other with a marine, plastic tone.

What makes Florhydral distinctive
The green muguet: more stem and leaf than petal, with a hyacinth side the softer alcohols do not have.
How Florhydral is used
Used as a freshener in florals and to exalt citrus, giving a lily-of-the-valley note.
Typical role: modifier (used in small amounts to change the character of a blend).
How Florhydral differs from similar materials
- Cyclamen Aldehyde
- Cyclamen aldehyde is more vegetal, with pronounced cucumber-melon notes; Florhydral is a fresher, more floral green muguet with hyacinth.
- Bourgeonal
- Bourgeonal is more aldehydic and watery-aquatic, with a woody drydown; Florhydral is greener, with a hyacinth facet.
- Silvial
- Silvial is a fresh, watery muguet aldehyde with a citrus undertone; Florhydral is greener and more natural, with hyacinth.
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.
