Ashland Aqualon EC N7 PHARM is a pharmaceutical - grade non - ionic ethyl cellulose, tailored for pharmaceutical preparation coating and industrial film - forming scenarios. It is a white powder, water - insoluble, soluble in various organic solvents such as ethanol and acetone, forming tough films that maintain flexibility at low temperatures
Preparation Isolation and Protection - Isolates APIs and components, prevents mutual reactions and discoloration of oxidizable components, ensuring stable drug efficacy
Excellent Membrane - Controlled Sustained Release - Can be used alone or combined with water - soluble components to prepare membrane - controlled sustained - release coatings, accurately regulating the release rate
Optimized Processing Performance - Improves powder flowability and compressibility, suitable for efficient molding of tablets/granules, reducing production loss
Organic Phase Solubility and Adaptability - Soluble in various organic solvents, suitable for different coating processes, forming uniform and dense films
