CAS number: 9004-57-3
Recommended Use: Industrial binder, coating agent, film former, pharmaceutical excipient
Manufacturer: Refer to product packaging or supplier details
Contact Information: Supplier emergency phone number available on outer packaging
Emergency Overview: Off-white powder or granules, odorless
Classification: Not classified as hazardous by OSHA or GHS guidelines
Major Hazards: Fine dust can form combustible mixtures with air; minimal health hazard with normal use, but inhalation of dust can irritate nasal passages
Pictograms: No symbol required under GHS
Signal Word: None
Precaution Statements: Avoid generating or breathing dust, avoid contact with eyes, provide adequate ventilation
Potential Health Effects: Eye contact causes mild irritation, dust may dry or irritate skin, dust inhalation can bother airways if exposure is excessive
Chemical Name: Ethyl Cellulose
CAS Number: 9004-57-3
Concentration: ≥ 99% by weight
Additives or Impurities: None required for typical food or pharmaceutical grade
Other Ingredients: Non-detectable levels of residual ethanol or ethyl chloride may be present due to manufacturing process
Eye Contact: Rinse with cool water for several minutes, remove contact lenses, lift eyelids to flush thoroughly; seek medical attention if irritation continues
Skin Contact: Wash exposed area using soap and water, remove contaminated clothing, observe for persistent irritation
Inhalation: Move to open space to breathe fresh air, loosen tight clothing, rinse mouth and nose with water if necessary
Ingestion: Rinse mouth out; seek medical care if feeling unwell or significant amount swallowed
Symptoms That Need Prompt Attention: Persistent cough, wheezing, severe skin or eye discomfort
Flammability: Product is combustible; powder or dust suspended in air can be explosive under certain conditions
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, foam
Unsuitable Media: Avoid strong water jets that could scatter burning dust
Special Hazards: Burns with formation of hazardous smoke (carbon monoxide, carbon dioxide, possible organic chemicals)
Personal Protection for Firefighters: Full protective gear and self-contained breathing apparatus recommended
Combustion Products: Carbon oxides, minor quantities of aldehydes or hydrocarbons from incomplete combustion
Personal Protection: Use disposable respirator or dust mask, goggles, gloves
Environmental Precautions: Avoid unintentional release into drains, ditches, or surface water
Methods for Clean-up: Sweep up carefully, avoid stirring up dust, use anti-static cleaning tools, collect in sealable container for proper disposal
Spill Volume Management: Dike to prevent spreading in case of large spill; keep away from sources of ignition
Emergency Procedures: Remove personnel not involved in cleanup and ventilate area
Safe Handling Advice: Store in tightly sealed original container, minimize dust production, handle only in well-ventilated places, wash hands after use
Storage Conditions: Keep container cool, dry, away from direct sunlight and heat sources, no contact with oxidizing substances
Incompatibilities: Keep separate from strong oxidizing agents, acids, bases
Material Packaging: Seal after each use; bulk quantities need grounding to prevent electrostatic ignition
Occupational Exposure Limits: No specific OSHA or ACGIH limits, but nuisance dust limits (15 mg/m³ total dust, 5 mg/m³ respirable) apply
Engineering Controls: Local exhaust or general mechanical ventilation recommended in dust-generating operations
Personal Protective Equipment: Dust mask or N95 respirator for heavy dust exposure, goggles for eye protection, nitrile or vinyl gloves
Good Hygiene: Clean up dust regularly, remove contaminated clothing, avoid eating or drinking while handling
Physical State: Fine powder or granules
Appearance: White to off-white

Relative Density: 1.08 – 1.18 g/cm³
Melting Point: Softens at above 120°C, decomposes above 200°C
Solubility: Insoluble in water, soluble in many organic solvents such as ethanol, toluene
pH: Not applicable (insoluble in water)
Flash Point: > 190°C
Auto-ignition Temperature: > 400°C
Vapor Pressure: Negligible
Partition Coefficient (n-octanol/water): Not determined
Other Properties: Forms static and combustible dust in dry air
Chemical Stability: Stable when stored under recommended conditions
Thermal Decomposition: Begins to break down above 200°C; forms carbon oxides and potential organic compounds
Hazardous Polymerization: Not expected under normal households or industrial settings
Incompatibility: Strong oxidizers (e.g., peroxides, chlorates), strong acids or alkalis
Reactivity: Exposed dust cloud may ignite with static, heat, or naked flames
Conditions to Avoid: Open flames, hot surfaces, uncontrolled sparks, strong static discharge
Acute Toxicity: Low oral and skin toxicity (not expected to cause acute health issues at normal exposure doses)
Chronic Exposure: No evidence of cumulative toxicity, no published evidence of carcinogenicity
Routes of Exposure: Inhalation, skin, eyes, ingestion
Symptoms: Mild respiratory tract irritation, mild skin or eye dryness
Sensitization: Not known to cause allergic sensitization
Reproductive Effects: No known risk in animal or human studies
Other Data: Not classified as hazardous under OSHA or EU chemical safety guidelines for end users
Environmental Impact: Not acutely toxic to aquatic or terrestrial life in typical usage or accidental release levels
Persistence: Biodegradable over time; natural microorganisms can break it down in landfill or soil
Bioaccumulation: Not expected to bioaccumulate
Mobility: Dust may disperse with wind and settle on soil or water
Other Effects: Large spills may temporarily raise BOD (biological oxygen demand) in aquatic environments
Aquatic Toxicity: No available data suggesting risk with practical concentrations
Waste Disposal: Collect and store for approved landfill disposal; can be incinerated at authorized facility
Disposal Regulations: Handle in accordance with local, regional, and national waste regulations
Recycling: Not suited for individual recovery from waste due to application (often mixed with other substances)
Container Handling: Empty containers must be thoroughly cleaned before recycling or re-use; avoid dust release during cleaning
UN Number: Not regulated for ground, air, or sea transport
Transport Hazard Class: Not regulated as dangerous cargo
Packing Group: Not applicable
