A green-floral acetal with a fresh, slightly waxy hyacinth-rose character. Softer and less pungent than the free aldehyde it derives from, adding a diffusive leafy-petal facet with a mild fruity nuance in the drydown.AI · claude-opus-4-7

Colorless oily liquid.
Very slightly soluble in water, soluble in alcohol and oils.
Powerful, sweet-green, slightly floral, rosy odor of considerable tenacity. However, the overall character is not very distinct, since it seems to have notes from Rose, Hyacinth, etc. blended with winey-weedy tonalities in an overall odor impression that leaves the observer somewhat confused.
This acetal could find use in Rose, Hyacinth, Appleblossom, etc. as well as in various types of Oriental fragrances. It may lend part of the desirable 'natural' greenness, accompanied by a certain amount of sweet floral notes.
Produced from Formaldehyde-di-iso-Amyl-acetal plus Phenylethyl alcohol — usually by short-time boiling.
