Product Description
Croscarmellose sodium is a sodium salt of a cross-linked carboxymethylcellulose polymer. It is a commonly used pharmaceutical excipient that is used as a disintegrant in tablet formulations. It works by absorbing water and swelling rapidly, creating channels in the tablet that allow water to penetrate and dissolve the drug more easily. This helps to break down the tablet into smaller particles that can be easily dissolved in the gastrointestinal tract.
Croscarmellose sodium can improve the dissolution and bioavailability of drugs, enhance the stability of suspensions and emulsions, and control the rate of drug release in controlled-release tablets. It is also easy to use and cost-effective.
Croscarmellose sodium is generally considered safe for use in pharmaceuticals. It has been used for many years and is approved by regulatory agencies such as the FDA. While it is primarily used in pharmaceuticals, it can also be used in other industries such as food and cosmetics as a thickener, stabilizer, and emulsifier.

Croscarmellose Sodium Applications:
1. Disintegrant: Croscarmellose sodium is primarily used as a disintegrant in tablet formulations. It helps to break down the tablet into smaller particles that can be easily dissolved in the gastrointestinal tract.
2. Binder: It is also used as a binder in the formulation of tablets. It helps to hold the ingredients together and prevent the tablet from falling apart.
3. Stabilizer: Croscarmellose sodium can also be used as a stabilizer in the formulation of suspensions and emulsions. It helps to prevent the separation of the different phases of the formulation.
4. Controlled release: Croscarmellose sodium can be used in the formulation of controlled-release tablets. It can control the rate of drug release by creating a barrier around the tablet and preventing the drug from being released too quickly.
5. Solubility enhancement: Croscarmellose sodium can enhance the solubility of poorly soluble drugs. It can do this by creating channels in the tablet that allow water to penetrate and dissolve the drug more easily.
How does it work:
CMC or carboxymethylcellulose (CMC) is a major ingredient in pharmaceuticals, and is widely used as a disintegrant in oral pharmaceutical formulations for capsules, tablets, and granules.
Side effects:
You cannot experience any "side effects" from croscarmellose sodium unless your body directly reacts to it. It has only been approved for use in small amounts by the Food and Drug Administration. It is not very likely to cause allergies. It can also cause adverse side effects in some, such as dyspepsia, hepatotoxicity, pancreatitis, interstitial nephritis, fever, headache, rash, nausea, vomiting, pneumonitis, pericarditis and so on.
