Ethyl Cellulose [18-22mPa·s, 5% in Toluene/Ethanol (80:20) at 25°C](CAS: 9004-57-3)

Ethyl Cellulose (CAS: 9004-57-3) is a semi-synthetic polymer derived from cellulose, modified with ethyl groups. It is characterized by its viscosity range of 18-22 mPa·s at 5% concentration in toluene/ethanol (80:20) at 25°C. This compound is insoluble in water but soluble in organic solvents, making it versatile for various applications in pharmaceuticals, industry, and research.

Ethyl Cellulose (CAS: 9004-57-3) is widely used as a film-forming agent, binder, and controlled release matrix in pharmaceuticals. It also serves as an adhesive in industrial coatings, a thickener in food products, and a material for research in drug delivery systems. Its unique solubility and viscosity properties make it ideal for applications requiring sustained release or structural integrity.

Ethyl Cellulose (CAS: 9004-57-3) is generally considered non-toxic and safe for use in food, pharmaceuticals, and industrial applications. However, handling precautions include avoiding inhalation of dust and skin contact. Safety standards ensure compliance with regulatory guidelines, and proper protective measures such as gloves and ventilation are recommended during processing.

Ethyl Cellulose (CAS: 9004-57-3) should be stored in a cool, dry place at 25°C, away from direct light. It requires a sealed container to prevent moisture absorption and maintain stability. Proper storage ensures consistent viscosity and prevents degradation, preserving its quality for use in pharmaceuticals, industry, or research.
