Features Of Ashland Natrosol HHX Pharm Hydroxyethyl Cellulose

  1. Pharmaceutical-grade purity compliant with USP/NF, EP, and JP monographs for use in parenteral, oral, and topical formulations.

  2. Consistent rheology profile with high solution clarity and low intrinsic viscosity variability across batches.

  3. Excellent cold-water solubility with rapid hydration and minimal gel lump formation under standard mixing conditions.

  4. Non-ionic nature ensures compatibility with cationic, anionic, and non-ionic excipients and active pharmaceutical ingredients (APIs).

  5. Thermally stable in aqueous solutions up to 80 °C and pH-stable across the range of 3–11.

Typical Applications Of Ashland Natrosol HHX Pharm Hydroxyethyl Cellulose

  1. Suspension stabilizer in oral liquid dosage forms (e.g., antibiotic suspensions and pediatric elixirs).

  2. Viscosity modifier and binder in immediate-release and extended-release tablet granulations.

  3. Rheology control agent in ophthalmic solutions and gels for enhanced corneal residence time.

  4. Matrix former in transdermal gels and hydrophilic wound dressings requiring controlled hydration and film integrity.

  5. Protective colloid in lyophilized protein formulations to prevent aggregation during freeze-drying and reconstitution.
