Usage
Use (Hekserij)
Aldehyde C9 has the characteristic fresh, yet greasy and also green citrus scent
of aldehydes. The smell is quite strong and therefore it is wise to make a
dilution of, for example, 10%. If you make this in alcohol, you have the
advantage that the shelf life of the aldehyde improves. Typical use is in rose
and citrus accords. You usually use a maximum of 0,5% of this substance in the
fragrance composition. It combines well with other aldehydes, but also with many
floral scents. It adds a touch of natural freshness. Some perfumers see it as a
top note, because it has the most effect in the top. Others just as a base note,
because the scent can be perceived right down to the base. Stability is not too
bad for an aldehyde, it is also reasonably useful in soap. In scented candles it
mainly has a good cold throw, while the candle is burning it produces little
odor. Keep cool, dry, dark and out of reach of children.
Physical properties
Properties (Hekserij)
Aldehyde C9 is a colorless to pale yellow liquid at room temperature. The purity
is at least 97%. The substance does not last very long, we recommend replacing
it about once a year. Dissolving in alcohol extends the shelf life. The
substance occurs in nature, but the synthetic version is used for use as a
fragrance.
