gelatin• It is derived from collagen found in the bones,

cartilage, connective tissue, and skin of animals, traditionally cows. Most commercially produced gelatin nowadays is produced from pig skin. If you have ever roasted a chicken or ham, you made your own gelatin. The juices in the bottom of the pan contain gelatin rendered from the collagen, and if you put the roasting pan in the refrigerator, you'll find some of the juice setting into a gel.

Musk• Musk is the name originally given to a

substance with a penetrating odor obtained from a gland of the male musk deer, which is situated between its stomach and genitals. The substance has been used as a popular perfume fixative since ancient times and is one of the most expensive animal products in the world. The name, originated from Sanskrit muṣká meaning "testicle," has come to encompass a wide variety of substances with somewhat similar odors although many of them are quite different in their chemical structures.
