Floral Butanal (Florhydral)
Premium Synthetic Ingredient for Perfumery
Florhydral® (Floral Butanal) is a synthetic aldehyde developed by Givaudan, prized in perfumery for its ability to impart a natural, green floral freshness reminiscent of lily-of-the-valley. Unlike many muguet-type molecules, it carries no IFRA restrictions, making it especially valuable in modern perfumery. Available in two enantiomeric forms, the (+)-(S)-isomer provides a greener, more powerful aroma, while the (−)-(R)-isomer leans toward a marine-plastic tone. Florhydral® performs well across formats—from fine fragrance to candles and joss sticks—and enhances both citrusand aldehydic top notes with clarity and modernity.

What is Florhydral®?
Florhydral®, chemically known as 3-(3-isopropylphenyl)butanal, is a synthetic linear aldehyde specifically formulated for perfumery use. It belongs to a class of floral-green modifiers often used to build lily-of-the-valley (muguet) accords. Unlike restricted materials such as hydroxycitronellal, Florhydral® is IFRA-unregulated, making it a flexible and safe choice for contemporary formulations.
The compound exists in two enantiomeric forms:
(+)-(S)-Florhydral®: Greener, more powerful, less watery
(−)-(R)-Florhydral®: Fresher, more marine, plasticky
These optical isomers differ significantly in olfactory profile and odor threshold:
(+)-(S): 0.035 ng/L (air)
(−)-(R): 0.88 ng/L (air)
Their distinct sensory qualities make Florhydral® a versatile tool in custom floral direction and diffusion control.
Olfactory Profile and Perfumery Applications
Florhydral® is widely appreciated for its muguet-type freshness—floral, green, and subtly watery. It is an excellent:
Top-note freshener for floral compositions
Modifier for citrus and aldehydic accords
Key muguet-builder in the absence of regulated materials
Supporter for green florals like hyacinth and lily
Its performance on paper and skin demonstrates medium strength, with a notable tenacity of around 7 days on blotters. In functional perfumery, it withstands heat, making it effective in:
Candles
Joss sticks and incense
Air fresheners
Synergy tip: When combined with Hedione or Lyral alternatives, Florhydral® boosts transparency and enhances bouquet clarity in white floral creations.
Industrial and Technical Uses
Florhydral® is used in:
Fine fragrance (muguet soliflores, floral-green bouquets)
Functional fragrance (cleansers, candles, room sprays)
Incense and combustion-safe applications
Botanical diffusers and green-themed accords
Its molecular design ensures stability under heating, making it suitable for burning delivery systems, where other floral materials may degrade or caramelize.
It is not authorized for flavor applications and has no FEMA GRAS status.
Regulatory and Safety Overview
IFRA: ✅ Not restricted (as of 51st Amendment)
EU Allergen Listing: ❌ Not among the 26 declarable fragrance allergens under Regulation (EC) No 1223/2009
FEMA GRAS: ❌ Not listed for ingestion
ECHA: Registered; not classified as hazardous in standard perfumery use
Toxicology: No known sensitization or phototoxicity reported at standard use concentrations
Stability: Good oxidative and thermal stability; low odor threshold allows low dosage for strong effect
✅ Suitable for wide use across perfumery applications, including heat-exposed formats.
