BLANOSE®Sodium Carboxymethylcellulose USP/NF, EP, JP
BLANOSE, Carboxymethylcellulose Sodium is the sodium salt of carboxymethylcellulose (CMC) which is an anionic, water-soluble polymer derived from cellulose reacted with sodium monochloroacetate. BLANOSE is soluble in cold or hot water, insoluble in organic solvents, compatible with water / alcohol systems & imparts low water and oxygen transmission to coatings.
BLANOSE grades find application as thickeners, binders, stabilizers, suspending agents and rheology modifiers. The grades designated P or PH are purified grades which meet pharmaceutical standards. A wide range of substitution types are also available, based on number of carboxymethyl groups present on the cellulose backbone. The low substitution grades (7 types) provide thixotropy whereas the higher substitution grades (9 and 12 types) provide smooth solutions without thixotropy.
*Also avaialbe in finely (X) ground grades.
*Viscosity in milli Pascal per second (mPas or cps) determined on aqueous solutions as per indicated weight %. at 250 C + 0.50 C using a Brookfield ‐ Syncro‐Lectric LVF viscometer.
