For a long time now, ambergris which is a waxy substance secreted from within sperm whales to protect their digestive systems against sharp objects has been prized by perfume-makers. The reason they like using ambergris in perfume is because that is what stops the smell from dissipating quickly. When the whales vomit, the ambergris from inside the whale reacts with the salt-water and solidifies into chunks that wash up a shore and get sold at nearly $10,000 a kilo. Scientists have been searching for an alternative since ambergris itself is expensive and excessive demand of it can lead to whale hunting.
