A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Croscarmellose sodium (CAS 74811-65-7), the internally cross-linked sodium salt of carboxymethylcellulose. Used as a superdisintegrant excipient in pharmaceutical and nutraceutical tablets and capsules, where it swells on wetting to break dosage forms apart. Supplied as a white powder.
Frequently Asked Questions
What is croscarmellose sodium used for in supplements and tablets?
Croscarmellose sodium (CAS 74811-65-7) is used as a superdisintegrant excipient in pharmaceutical and nutraceutical tablets and capsules. On contact with water it swells rapidly, breaking the dosage form apart to aid dissolution. It functions as a formulation aid in solid oral dosage manufacture.
Is croscarmellose a natural ingredient?
Croscarmellose sodium is the internally cross-linked sodium salt of carboxymethylcellulose, a cellulose derivative. The base cellulose is plant-derived, but the material is chemically modified (carboxymethylated and cross-linked), so it is a processed cellulose derivative rather than an unmodified natural substance.
Is croscarmellose sodium water soluble?
Croscarmellose sodium is not freely water soluble; the internal cross-linking causes it to swell and absorb water rather than dissolve, which is exactly what drives its disintegrant action. Refer to the product SDS and technical data sheet for handling and dispersion details.
What grade and packaging does RawSource supply croscarmellose sodium in?
RawSource supplies croscarmellose sodium as a white powder for excipient use, classified under HS code 3912.31 (carboxymethylcellulose and its salts). Grade documentation, packaging, and lot size are confirmed per order, with a CoA and SDS provided. Request a bulk quote with your required specification and quantity.
What is the cost of bulk croscarmellose sodium?
Bulk pricing varies by grade, packaging, order volume, and destination, so it is quoted per order rather than published. Submit a bulk RFQ with your quantity and spec and RawSource will return current pricing.
