Carboxymethylcellulose sodium (CMC-Na) is a water-soluble cellulose ether widely used as a thickener, stabilizer, binder and suspending agent across pharmaceutical, food and personal care applications. Produced by substituting carboxymethyl groups onto a cellulose backbone, it dissolves easily in water to form clear, viscous solutions with excellent rheological control.
Carboxymethylcellulose Sodium – Thickener, Stabilizer & Suspending Agent from TCS GROUP is tailored for oral liquids, topical preparations and solid dosage forms. In syrups, suspensions and emulsions, CMC-Na provides viscosity and suspension stability, helping to keep insoluble drug particles evenly dispersed and preventing sedimentation. Its film-forming and water-binding capabilities also contribute to smooth mouthfeel and long shelf life.
In semi-solid dosage forms such as gels and creams, CMC-Na acts as a gel matrix and stabilizer, improving spreadability and preventing phase separation. In tablets and capsules, it can function both as a binder and, at higher levels or specific grades, as a disintegrant or controlled-release aid.
TCS INDUSTRIES LIMITED positions CMC-Na as part of a comprehensive excipient toolkit. For example:
- Croscarmellose Sodium – Superdisintegrant for Rapid Tablet Disintegration can be combined with CMC-Na to deliver fast disintegration while CMC-Na fine-tunes viscosity or binding in direct compression and wet granulation formulas.
- Anhydrous Sodium Carbonate can be used alongside CMC-Na in effervescent or pH-adjusted systems where controlled viscosity and suspension behaviour are critical.
Formulators can explore the full excipient line-up via the Pharmaceutical Excipients page, matching CMC-Na with fillers, disintegrants and lubricants for optimised performance.
Key advantages of CMC-Na from TCS GROUP include high purity, consistent degree of substitution (DS), controlled viscosity grades and excellent batch-to-batch reproducibility. These attributes help secure predictable rheology and processing behaviour across different dosage forms.
Whether used in oral suspensions, topical gels or multifunctional tablets, Carboxymethylcellulose Sodium from TCS GROUP offers formulators a versatile, well-understood polymer backbone for modern, patient-friendly products.
