Hydrofleur ® BRI

from €7.90

Premium Synthetic Aldehydic Muguet Floralizer

Hydrofleur (CAS 62439-42-3) is a proprietary synthetic floralizer developed by Bedoukian Research Inc. in collaboration with P2Science, utilizing 100% renewable feedstocks under the principles of green chemistry. This high-impact aldehydic material presents a crisp ozonic and mossy-fresh opening that rapidly transitions into a clean, radiant muguet (lily of the valley) profile. The core floralcy is further characterized by subtle, aquatic-luminous nuances and distinct fruity facets of melon and raspberry, offering a modern, highly diffusive alternative to traditional floral modifiers like hydroxycitronellal.

Functionally, Hydrofleur acts as a powerful freshener and floral booster, requiring extremely low dosages (typically trace amounts to <1.0%) to achieve significant olfactory impact. Its radiant character enhances projection in white floral accords, particularly tuberose and muguet reconstructions, while maintaining stability across complex bases.

As a fully biodegradable molecule with no currently listed EU allergens, it provides formulators with a highly compliant, sustainable tool for introducing aquatic-floral transparency and lift to contemporary fine fragrance applications.

What is Hydrofleur?

Hydrofleur is a novel synthetic ingredient designed to support high-impact olfactory performance at minimal dosage, introduced by Bedoukian Research Inc. in partnership with P2Science. It debuted at the World Perfumery Congress (WPC) 2018 in Nice, during a session on sustainable innovation in signature ingredients.

The molecule belongs to a class of proprietary aldehydic floralizers and was developed to replicate the complexity and radiance of traditional floral modifiers like Hydroxycitronellal, but with improved sustainability and performance at extremely low concentrations.

Olfactory Profile & Perfumery Applications

Hydrofleur opens with a crisp ozonic freshness touched by aldehydic and mossy aspects. Within minutes, the heart reveals a clean muguet floralcy, accompanied by white floral notes of tuberose and a subtle sweetness suggestive of melon and raspberry. It imparts a radiant and aquatic-luminous character, contributing to both projection and complexity.

Applications:

  • Floral and fruity fragrances

  • Lily of the valley, tuberose, and aquatic florals

  • Radiant top notes and clean white flower effects

  • Green aldehydic blends

  • Modern clean-fresh or marine perfumery

Its role is similar to traditional floralizers, but it is distinguished by extremely high impact at trace concentrations, clean character, and formulation compatibility. Hydrofleur performs well even in complex bases like Chanel No.5-type blends.

Sustainable Manufacturing & Green Chemistry Alignment

Hydrofleur is manufactured using renewable raw materials and adheres to the 12 Principles of Green Chemistry, including:

  • Use of renewable feedstocks

  • Design for degradation

  • Less hazardous chemical synthesis

  • Atom economy

  • Real-time pollution prevention

This aligns the material with modern Clean Beauty and Clean Fragrance standards, providing a functional aromatic material with minimal environmental impact.

Regulatory & Safety Overview

  • IFRA: No specific restrictions listed under current IFRA Amendments

  • Allergens: No known EU-listed allergens in pure form

  • Sustainability: 100% renewable origin

  • Biodegradability: Aligned with principles of degradable molecular design

  • Formulation Notes: Extremely powerful — typically used at <1%; compatible with most media types

Additional Information

  • First Presentation: WPC 2018 (Nice) by Robert Bedoukian

  • Collaborators: Developed with P2Science

  • Recommended Concentration: Trace to <1.0% in fragrance concentrate

  • Comparative Benchmark: Hydroxycitronellal (less green opening, more stable radiance in Hydrofleur)

  • Material Class: High-impact aldehydic floral
