Запах

Fresh, clean rosiness on first contact — immediately recognizable as rose, with a citronellol softness and a geraniol brightness. More natural-smelling than phenylethyl alcohol, more specifically rose than geraniol alone. A sweet nerol layered adds delicacy. Less green than geranium oil, less honeyed than rose absolute, closer in spirit to the clean, dewy scent of a freshly opened Damascena rose. The dry-down is soft, warm, and persistently rosy.

Теруар і походження

Докладно

Rhodinol is the molecular soul of rose — not a single compound but a carefully isolated fraction of geranium essential oil that concentrates three terpene alcohols that are also major constituents of rose oil: chiefly citronellol and geraniol, with a smaller share of nerol.

The isolate is obtained by fractional distillation of geranium (Pelargonium) oil, separating the 'rose alcohol' fraction from the greener, mintier terpenes that give geranium its characteristic leafy bite. The finest grades — Rhodinol ex Geranium Bourbon — come from Reunion Island geranium, historically known for exceptionally rosy profile.

In perfumery, rhodinol is the workhorse of rose accords. It provides a natural-smelling rosiness that phenylethyl alcohol (the standard rose synthetic) alone cannot achieve — PEA gives the 'fresh rose petal' impression but lacks the fuller, more complex character of the natural alcohol mixture. Rhodinol is also used in geranium reconstitutions, lily of the valley accords (where it provides the rosy quality), and citrus-floral compositions where a clean, natural-smelling floral body is needed.

Отримання й хімія

Спосіб отримання

Fractional distillation of geranium (Pelargonium graveolens or P. roseum) essential oil. The geranium oil is itself steam-distilled from the leaves and stems of the plant. Rhodinol is isolated as a specific fraction — the 'rose alcohol' cut — that concentrates citronellol, geraniol, and nerol while removing the greener, mintier terpenes. The finest grades come from Bourbon geranium (Reunion Island) and Egyptian geranium. Rhodinol is a colorless to pale yellow liquid with a fresh, rosy scent.

У парфумерії

Rhodinol is a natural isolate obtained by fractional distillation of geranium (Pelargonium) essential oil, rich in citronellol and geraniol. Citronellol (CAS 106-22-9) provides the soft, rosy-fresh body; geraniol (CAS 106-24-1) adds the brighter, more geranium-like lift; nerol contributes a sweeter, more delicate floral layer. In perfumery, rhodinol functions as the backbone of rose accords, providing a natural-smelling rosiness that is more convincing than pure phenylethyl alcohol (the 'classic' rose synthetic). It is used in rose, geranium, lily of the valley, and citrus-floral compositions. The 'Bourbon' designation (Rhodinol ex Geranium Bourbon) refers to geranium oil from Reunion Island, historically considered the finest quality.
