Grey amber is an animal substance coming from a
pathological secretion in the intestines of the sperm whale. Its
obtention in no way endangers the animal as it can be found floating
on the ocean's surface or simply along the coastline. The perfume
industry uses it as a trace, like musk or civet, to fix or exalt
other perfumes which might be too delicate or fleeting. It is
too expensive to be used in soap.
Origin
Sumatra Isles, Madagascar; along the coasts of America, Brazil,
China, and Japan.
