Hydroxypropyl Methylcellulose

Hydroxypropyl methylcellulose, also known as carbohydrate gum, is made from natural cellulose obtained from pine trees (Pinus species) or cotton (Gossypium species) linters (the fuzz that adheres to cottonseeds). The natural cellulose is then modified to form a gum or gel like material (modified cellulose).


Hydroxypropyl methylcellulose serves as an excellent means of binding tablet ingredients together. As a component of the tablet coating, it also aids the ease of tablet swallowing.
