I am planning to realize a project here with Basenoters about animal scents, more particularly with the little known Hyraceum.
You can have info about this material and the little animal at the Hyraceum page.
Hyraceum is the secret ingredient of Duchauffour and Denyse Beaulieu in "Aube a Seville".
This project would be about the effect of Hyraceum on your favorite perfume. How would it change it in intensity, longevity, sillage and above all would it raise the attention of people on you, being a pheromone ingredient.
It should be remembered that this aromatic material is rare, existing only in a small region of South Africa, where it is found in fossilized deposits whose number is very limited. As Hyraceum becomes known and requested, the deposits will likely be finished in 20 years or so.
However, by fortune the animal who produces it cannot be killed or held in captivity for its perfume. Read the details on the Hyraceum page.
