Florol® (Firmenich)

Description

A soft and diffusive floral note with exceptional freshness is the hallmark of this versatile pyranol. The olfactive profile is characterized by a prominent lily-of-the-valley (muguet) heart, tinged with the delicate woody-rosy nuances of bois de rose. Its scent is simultaneously clean and natural, evoking the dewiness of white petals without any heavy or indolic facets. The chemical structure of Florol®, a tetrahydropyranol derivative, contributes to its unique stability and radiant quality, making it a staple for perfumers seeking a modern and luminous floralcy.

In application, the ingredient provides significant lift, bloom, and volume to a composition. It is a fundamental building block for creating realistic muguet and white floral accords, blending seamlessly with materials like hydroxycitronellal, lilial, and cyclamen aldehyde. Its utility extends beyond simple floral bouquets; it freshens citrus top notes, softens aldehydic complexes, and adds a natural touch to fruity and green fragrances. Recommended usage levels for Floral pyranol can range from a modest 1% to add a subtle floral breath, up to 10% in formulas where its bright character is a central theme, proving its value across fine fragrance, personal care, and fabric care.
