Sodium carboxymethyl cellulose (CMC) is a widely used pharmaceutical excipient in the pharmaceutical industry. It is a white, odorless, tasteless powder that is composed of cellulose and sodium carboxymethyl groups. CMC is used in a variety of pharmaceutical formulations, including tablets, capsules, suspensions, and emulsions. It is also used as a stabilizer, thickener, and binder in many pharmaceutical products.
CMC is used in the pharmaceutical industry for a variety of purposes, including:
1. As a binder: CMC is used to bind together active ingredients in tablets and capsules. It helps to increase the strength and stability of the tablet or capsule.
2. As a disintegrant: CMC helps to break down tablets and capsules in the digestive tract, allowing for faster absorption of the active ingredients.
3. As a suspending agent: CMC helps to suspend active ingredients in a liquid medium, allowing for easier administration of the drug.
4. As an emulsifier: CMC helps to keep oil and water-based ingredients mixed together in emulsions.
5. As a stabilizer: CMC helps to stabilize active ingredients in a formulation, preventing them from separating or settling out.
6. As a thickener: CMC helps to thicken liquid formulations, allowing for easier administration of the drug.
7. As a lubricant: CMC helps to reduce friction between tablet components, allowing for easier tablet manufacturing.
