By and large of little or no use to the perfumer, there is yet one application for which this aldehyde seems to be quite suitable: for artificial Mimosa absolute, or in “Mimosa” bases. The choice of materials truly suitable for Mimosa bases is extremely small, and any material which has a useful effect should be very welcome. This special application may also lead to the use of Hexadecanal in other floral fragrances or bases, e. g. Tuberose, Cassie, Peony, etc. and the aldehyde blends very well with the Ionones in an artificial Cassie composition.
