Usage
Use (Hekserij)
Aldehyde C12 lauryl has the characteristic aldehyde smell: a bit greasy and
soapy, but more in the direction of soapy. With some effort, it also has
something orange-like. The scent is strong, for that reason alone making a
dilution of, for example, 10% is recommended. We generally don't recommend using
alcohol when making dilutions, but this is an exception: alcohol stabilizes many
aldehydes so they last longer. Typical use is in aldehyde and citrus accords. In
addition, it is used in floral scents, especially cyclamen, rose and green
floral scents. You rarely use more than 0,2% in the fragrance composition. It is
always an accent that promotes freshness and radiance. In perfumes it is often
dominant in the top, but because it does not evaporate quickly, it is actually a
base note. It can be used in soap, but dose a little higher, it's not very
stable in it.

Properties (Hekserij)
Aldehyde C12 lauryl is a colorless to pale yellow liquid at room temperature.
The purity is at least 97% immediately after making. The substance does not have
a long shelf life, not only is it sensitive to oxygen, it also reacts with
itself. It polymerizes and forms trimers, which become visible as white flakes
in the liquid. You can filter this out, but it is better to replace this
substance regularly, at least once a year.
