How it behaves

Descriptors
floralgreen

A fresh floral-green material with a bright, dewy lily-of-the-valley character and a soft citrus-aldehydic lift. Smoother and less pungent than hydroxycitronellal itself, with a clean, slightly waxy floral trail that lasts well into the dry-down.AI · claude-opus-4-7

Appearance

Colorless viscous oil.

Solubility

Insoluble in water, soluble in alcohol and oils.

Odor

Very mild, refreshing, green-floral, citrus-like, lemon-type odor of good tenacity.

Uses in perfumery

This acetal remains therefore, largely a curiosity, rather than a standard shelf item in the perfume laboratory.

Production

Produced from formaldehyde diethyl acetal plus hydroxycitronellol by short-time boiling.
