Ethyl Cellulose CAS 9004-57-3

1. Ethyl cellulose is a versatile cellulose derivative used as a film-forming agent, binder, and viscosity modifier in pharmaceutical formulations for controlled-release tablet coatings, taste masking, and moisture protection .
2. Ethyl cellulose CAS 9004-57-3 serves as a thickening agent and stabilizer in food products, and as a non-caloric, non-allergenic binder in processed foods and nutritional supplements .
3. Ethyl cellulose is employed in industrial coatings for paper, textiles, and leather, providing water resistance, gloss, and durability, and is used as a carrier for inks, adhesives, and printing pastes .
4. In cosmetics and personal care products, ethyl cellulose functions as a film former and thickening agent in mascaras, hair sprays, and lotions, offering improved texture and water resistance .

1. Ethyl cellulose must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, protected from heat, sparks, and open flames; recommended storage at room temperature in a cool, dark place .
2. Ethyl cellulose CAS 9004-57-3 is classified as a combustible solid (flash point 75-110°C depending on the solution grade) and may form explosive dust mixtures with air when finely dispersed .
3. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance, ensuring adequate ventilation and avoiding formation of dust and aerosols .
4. Keep away from incompatible materials such as strong oxidizing agents, strong acids, and strong bases to prevent decomposition; store separately from foodstuff containers .

1. Isolate the spill area immediately, ensure adequate ventilation, and eliminate all sources of ignition; wear full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable dust respirator .
2. Collect Ethyl cellulose CAS 9004-57-3 by sweeping or vacuuming without creating dust using non-sparking tools, and place into suitable closed containers for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; prevent the product from entering drains or water courses .
4. Dispose of collected material according to local, state, and federal environmental regulations through licensed chemical destruction or controlled incineration .

1. Ethyl cellulose is a combustible solid with a flash point ranging from 75°C to 110°C; under fire conditions, it may decompose, emitting toxic fumes including carbon monoxide, carbon dioxide, and other irritant gases .
2. Use water spray, dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires involving the product; do NOT use a direct water jet as Ethyl cellulose CAS 9004-57-3 may scatter burning material .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning ethyl cellulose due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; contain fire runoff to prevent environmental contamination .
