Blanose 7HF Sodium Carboxymethylcellulose (CMC) | 25 kg Bag
Blanose CMC 7HF is an Ashland sodium carboxymethylcellulose, commonly referred to as CMC, sodium CMC, or carboxymethylcellulose. Ashland identifies this grade as a high-purity sodium carboxymethylcellulose used as a rheology modifier and in pharmaceutical applications.
Blanose CMC 7HF is supplied as an off-white, odorless powder. It is soluble in water, with solubility limited by viscosity, and is designed for formulations where controlled viscosity and rheological modification are required.
Ashland specifies a 1% solution viscosity of 1,500 to 2,500 mPa·s, along with a degree of substitution range of 0.65 to 0.90 and a pH range of 6.5 to 8.5. These defined specifications help formulators evaluate Blanose CMC 7HF for processes requiring a consistent sodium carboxymethylcellulose grade.
Common Applications
- Rheology-modification applications
- Pharmaceutical formulations
- Formulations requiring sodium carboxymethylcellulose
- Applications requiring controlled viscosity in aqueous systems
Suitability and use level should be evaluated based on the specific formulation, processing conditions, and applicable regulatory requirements.
