Features Of Ashland Aqualon N7 Ethyl Cellulose

High ethoxy content (47.5–49.5%) for excellent organic solvent solubility and film-forming capability.
Low viscosity grade enabling easy handling, efficient dispersion, and compatibility with high-solids formulations.
Thermoplastic behavior with good thermal stability up to 160°C, supporting hot-melt and melt-processing applications.
Non-ionic nature ensures broad compatibility with APIs, pigments, resins, and plasticizers without ionic interference.
USP/NF and EP compliant, suitable for pharmaceutical and food-contact applications where regulatory acceptance is critical.

Typical Applications Of Ashland Aqualon N7 Ethyl Cellulose

Controlled-release matrix tablets and multiparticulate systems in oral solid dosage forms.
Binders and film formers in pharmaceutical tablet coatings and granulation processes.
Viscosity modifiers and rheology control agents in industrial coatings and inkjet inks.
Encapsulation matrices for fragrances, pesticides, and agrochemical active ingredients.
Base polymer for hot-melt extrusion (HME) and melt-blending of functional composites.
