Profile

Citronellal is curated in this catalog as a zesty material, with a secondary reading of green.

On the strip it reads citronella lemon green.

It is registered under CAS 106-23-0.

The catalog records an average working dose of 5% Max%, which is a starting point for a trial rather than a limit.

How it behaves

volatility index 0.68 · the opening

A boiling point of 205 °C and a molecular weight of 154.25 g/mol give Citronellal a volatility index of 0.68, which places it in the opening of a composition.

It leaves the strip early and does its work in the first minutes, before the heart arrives.

The index runs from 0 for a material that barely leaves the strip to 1 for one that flashes off, and it is computed from boiling point and molecular weight. Inside a real formula the surrounding materials shift where the boundaries fall, so a material can read differently there than it does here.

Questions about Citronellal

What does Citronellal smell like?

Citronellal reads as zesty and green, described in the catalog as citronella lemon green.

Is Citronellal a top, heart or base note?

Citronellal sits in the opening. Its volatility index of 0.68 is computed from a boiling point of 205 °C and a molecular weight of 154.25 g/mol, rather than assigned by hand. It leaves the strip early and does its work in the first minutes, before the heart arrives.

How much Citronellal should I use?

The catalog records an average working dose of 5% Max% for Citronellal. Treat that as the starting point for a trial: the right dose depends on what else is in the formula and what you want it to do there.

What can I use instead of Citronellal?

The closest materials in this catalog by olfactive profile and physical behaviour are LIME OIL DISTILLED 5X (Non-Sensitizing) (88.5% match), Lemongrass Oil P&N (87.4% match) and Aldehyde C-10 (decanal) (81% match). Closeness is scored on descriptor taxonomy and on measured properties, so the nearest match is the one that behaves most like Citronellal. Ranking ignores price.

What is the CAS number for Citronellal?
