Features Of Ashland BLANOSE CMC 7LF PH Carboxymethylcellulose Sodium

  1. Highly purified, low-ash sodium carboxymethylcellulose optimized for pH-sensitive formulations.

  2. Controlled low viscosity profile (7 mPa·s in 2% aqueous solution) enabling easy handling and rapid hydration.

  3. Consistent neutral to slightly alkaline pH (6.5–8.5), minimizing risk of degradation in acid-labile systems.

  4. Excellent water solubility and colloidal stability across a broad temperature range (5–60 °C).

  5. Complies with USP/NF, EP, and JP monographs for pharmaceutical and food-grade use where permitted.

Typical Applications Of Ashland BLANOSE CMC 7LF PH Carboxymethylcellulose Sodium

  1. Stabilizer and thickener in liquid oral suspensions and ophthalmic solutions.

  2. Rheology modifier in low-pH personal care products, including facial toners and exfoliating gels.

  3. Viscosity builder and suspension aid in agricultural adjuvants and pesticide concentrates.

  4. Binding agent in pharmaceutical wet granulation processes requiring minimal thermal or shear sensitivity.
