Florol®

Uses in perfumery :

Florol® is used to replace Hydroxycitronnellal, for regulatory reasons, for lily of the valley or lilac accords in particular. However, it is less fresh and floral-lily of the valley than Hydroxycitronellal. Also used for its stability.

Year of discovery :

Discovered in 1986. "Florol®" tradename has been published and protected by Firmenich SA since 18/02/1988 (brand N°521114)

Natural availability :

Florol® is not available in its natural state.

Isomerism :

The molecule has an asymmetric carbon, but it is the racemic mixture of Florol® that is used in perfumery. Hydroxycitronellal is a constitutional isomer of Florol®. Moreover, these two molecules are used for the same purpose in perfumery: often for reproductions of lily of the valley notes. In compositions, Florol® tends to replace Hydroxycitronellal as it is not regulated.

Synthesis precursor :

Florol® is not a precursor to the synthesis of another compound of olfactory interest.

Synthesis route :

The synthesis of Florol® is made by cyclocondensation between 3-methyl-3-buten-1-ol and 3-methylbutanal, on silica gel and aluminum oxide, and in the presence of solvent.

Stability :

Unstable in acidic products, except in fabric conditioners, and in alkaline products, except powder detergents.

Other comments :

Unlike Hydroxycitronellal, Florol® is not regulated or allergenic.

Allergens :

This ingredient does not contain any allergen.
