Usage
Use (Hekserij)
Omega pentadecalactone has a somewhat sweet fruity musky scent. The scent is
quite strong, however, because the substance is solid at room temperature, it
can be useful to make a solution of it. Making a 10% dilution can actually be
done in all common solvents, if you heat it on a water bath. For a more
concentrated solution, IPM is a good choice. Typical use is in a musk accord.
You usually use between 0,2% and 20% of this substance in the fragrance
composition. It combines well with other musks, but also with floral and fruity
scents. In perfumes it is mainly a base note, it is stable in most products,
also in soap.

Properties (Hekserij)
Omega pentadecalactone is a colourless solid at room temperature. We pour this
in the molten state into the packaging, after which it solidifies. The purity is
at least 98,5% and the substance has a fairly long shelf life. Men are said to
smell this substance better than women, but convincing evidence for that idea is
lacking. By the way: as with almost all musks, there are relatively many people
who do not notice the smell at all. It occurs in nature, angelica extracts
contain up to 5% of this substance. The material we sell is synthetic. This
version has been in production since 1927, a remarkable achievement at the time,
it is not a simple process. We sell the same molecule under the name Macrolide
(Sym), but because that Symrise branded product is sometimes temporarily
unavailable, we also sell this unbranded alternative.
