Ambergris used to be very highly valued by perfumers as a fixative that allowed the scent to last much longer, but it has been replaced by synthetic ambroxan. The word ambergris comes from the Old French "ambre gris" or "grey amber ". Ambergris is formed from a secretion of resources from a sperm whale
bile duct in the intestines of the sperm whale, and can be found floating on the sea or washed up on the resources from a sperm whale.
It is also sometimes found in the abdomens of dead sperm whales.
