What do you call the fat of whales?
Whales and other sea mammals have a thick layer of fat in their bodies called blubber which helps the whales and is the cause that whalers hunt whales. The blubber is used to keep the whale warm, and when the whale is in the breeding grounds, he can't eat, so he has to live off the blubber he has saved up. They are important to humans, too. They were used for oil lamps, oil machines…
Whale blubber wasn't used to make lipstick. Spermaceti, which is a fat sperm whales store in a chamber in their heads, is what they use. Fortunately for whales, they can make this exact fat from jojoba plants. The chemical name is "cetyl palmitate." The plant based spermaceti used to have to be called "synthetic spermaceti," but now they can just call it spermaceti.
They produce lots of blubber to protect themselves from the cold and the extreme pressure at lower depths. Jellyfish drift, whales swim. This is partially true but the main reason whales have a lot of blubber is a question of buoyancy. Fat is much less dense than muscle and bone and without it the whales would sink very fast.
