Blanose CMC Sodium Carboxymethylcellulose | 25 kg Bag
Blanose CMC is a high-purity sodium carboxymethylcellulose from Ashland. Commonly referred to as CMC, sodium CMC, or cellulose gum, this 9M31XF grade is used as a rheology modifier in formulations where controlled viscosity and water-soluble functionality are required. Ashland identifies the material as 99.5% high-purity sodium carboxymethylcellulose with CAS number 9004-32-4.
Blanose CMC 9M31XF is supplied as an off-white, odorless powder. It is soluble in water, with solubility limited by viscosity, making it suitable for aqueous systems where formulators need to modify flow and viscosity characteristics.
Ashland specifies a 2% solution viscosity of 1,500 to 3,100 mPa·s, a degree of substitution of 0.80 to 0.95, and a pH range of 6.5 to 8.5. These defined specifications help formulators select a consistent CMC grade for manufacturing and product development.
The accompanying Certificate of Analysis also lists a minimum purity of 99.5% and states that the tested lot complies with current FCC, E466, and JECFA INS 466 requirements.
Common Applications
- Rheology-modification applications
- Aqueous formulations requiring viscosity control
- Formulations requiring sodium carboxymethylcellulose
- Applications requiring a water-soluble cellulose gum
- Food formulations where a compliant CMC grade is appropriate
Suitability and use level should be evaluated for the specific formulation, processing conditions, intended market, and applicable regulatory requirements.
