Usage
Use (Hekserij)
Cinnamic aldehyde has a sweet spice fragrance reminiscent of cinnamon and
cinnamon flavored candy. The scent is strong, so making a dilution of, for
example, 10% in DPG can be useful. Typical use is in spice accords, especially
cinnamon, or as a spice accent in fruit and floral fragrances. You usually use
between 0,1% and 2% of this substance in the fragrance composition. It combines
well with other spice scents, as well as sweeter fruit and floral scents. It
adds warmth and sweetness to the fragrance. In perfumes it is mainly a base
note. Although not very stable, it is sometimes used in soap.

Properties (Hekserij)
Cinnamic aldehyde is a colourless to slightly yellow liquid at room temperature.
The purity is at least 98% and the substance has a limited shelf life: it is
sensitive to attack by oxygen, where it turns into cinnamic acid. Although
cinnamic acid is not more harmful to the skin than cinnamic aldehyde, it has a
much less strong odour. It occurs in nature, but for use as a fragrance, the
synthetic version is used. This is based on petrochemicals.
