Common Names: PVA, PVOH, Polyvinyl Alcohol Resin
Synonyms: PVA Modified, Water-Soluble Polymer
Manufacturer: Provided on request per regulatory rules
Recommended Use: Adhesives, paper coatings, textile sizing, specialty films
Emergency Telephone Number: Local Poison Control and Fire Services
Hazard Classification: Not classified as hazardous in most finished forms, but dust and powder forms may irritate eyes and respiratory system
Physical Hazards: Low risk, can support combustion in dust form
Health Hazards: Eyes and skin may experience dryness, irritation after direct and prolonged contact; inhaled dust can aggravate asthma or respiratory issues
Environmental Hazards: Not acutely toxic to aquatic life at normal concentrations but large spills in waterways increase chemical oxygen demand
GHS Label Elements: No pictogram required; advisory “avoid generating dusts”
Precautionary Statements: Wear eye, skin, and respiratory protection in dusty conditions
Signal Word: None
Principal Ingredient: Polyvinyl Alcohol – 90% to 99%
CAS Number: 9002-89-5
Modifying Agents: Less than 10% (Usually acetate, aldehyde, or carboxylic groups)
Additives: Small quantities of surfactants or plasticizers may be present
Impurities: Residual monomers, sodium acetate, trace unreacted catalysts
Eye Contact: Flush open eyes gently with running water for minimum 10 minutes; remove contact lenses; seek medical attention if irritation persists
Skin Contact: Wash with soap and water; remove contaminated clothing and wash before reuse
Inhalation: Move to fresh air; observe for coughing, persistent irritation, or shortness of breath; consult a healthcare provider if symptoms present
Ingestion: Rinse mouth with water; drink water to dilute; medical advice for large amounts or adverse symptoms
Most Important Symptoms/Effects: Temporary redness, itching, sore throat, or mild cough
Suitable Extinguishing Media: Water spray, foam, dry chemical, or carbon dioxide; avoid high-pressure direct streams on dust
Specific Hazards: Burning may produce carbon monoxide, carbon dioxide, acetic acid vapors, and other gases; dust in air forms explosive mixtures
Special Protective Equipment: Full protective clothing and self-contained breathing apparatus; control and contain runoff
Special Procedures: Clear personnel downwind; cool fire-exposed containers; ventilate fire area
Personal Precautions: Use appropriate glove, mask, and eye protection; prevent inhalation and direct contact
Environmental Precautions: Prevent bulk material from entering sewers or waterways; absorb small releases with sand or soil
Cleanup Methods: Shovel or vacuum spilled solid into labeled containers; sweep up residue and minimize dust generation; dispose of in accordance with regulations
Precautions for Safe Handling: Keep containers tightly closed; avoid breathing dust or mists; handle with appropriate engineering controls
Storage Conditions: Store in a dry, cool, well-ventilated area away from strong acids, oxidizers, and heat sources; avoid moisture to prevent clumping
Incompatibilities: Strong acids, strong oxidizing agents
Packaging Materials: Use moisture-barrier bags, drums lined with plastic, or sealed fiber boxes
Occupational Exposure Limits: No established ACGIH, OSHA, or NIOSH exposure limits; manufacturers recommend keeping airborne concentration below 10 mg/m3 (total particulate)
Engineering Controls: Local exhaust ventilation, dust collection systems on process lines, and closed transfer techniques
Personal Protection: Safety goggles, chemical-resistant gloves, respiratory protection in dusty environments, protective clothing if large exposure possible
Hygiene Measures: Wash hands before eating, drinking, smoking, or after handling; avoid touching eyes and face
Appearance: White to off-white powder, fine granules, or pellets; clear when dissolved in water
Odor: No noticeable odor
pH: 5.0 to 7.0 in aqueous solution (4% solution)
Melting Point: Begins to soften above 200°C; decomposes before melting
Boiling Point: Not applicable—decomposes
Flash Point: Over 200°C, dust can ignite at much lower temperatures
Solubility: Easily dissolves in water at 70–90°C; insoluble in organic solvents
Density: 1.19–1.31 g/cm3 (solid)
Vapor Pressure: Negligible at room temperature
Viscosity: Highly variable, depends on molecular weight and degree of polymerization
Chemical Stability: Stable at room temperature in dry, inert atmospheres
Conditions to Avoid: High humidity, excess heat, ignition sources, strong acids, and oxidizing agents
Hazardous Decomposition Products: Burning generates carbon monoxide, carbon dioxide, and possibly volatile organic acids
Hazardous Polymerization: Does not occur under normal conditions
Acute Toxicity: Modified polyvinyl alcohol shows very low acute oral and dermal toxicity in animal studies; large doses may irritate gut
Chronic Effects: Available data does not suggest chronic health risks from occupational exposure under standard handling practices
Skin Irritation: Prolonged or repeated contact may dry or redden skin
Eye Irritation: Direct contact causes temporary mild to moderate irritation
Respiratory Effects: Inhaled dust can irritate the nose and throat
Carcinogenicity: Not listed as a carcinogen by NTP, IARC, or OSHA
Mutagenicity & Reproductive Toxicity: No evidence found in published studies
Aquatic Toxicity: Low acute toxicity to aquatic life; death unlikely except in cases of huge spills
Persistence and Degradability: Biodegradable under typical environmental conditions due to microbial action
Bioaccumulation Potential: Not bioaccumulative, does not build up in aquatic organisms
Mobility in Soil: Water soluble, low adsorption in soils, moves with groundwater
Other Adverse Effects: Bulk releases may deplete oxygen in waterways; runoff control essential near streams and lakes
Waste Treatment Methods: Dispose of by landfill or incineration in accordance with government regulations
Unused Product: Collection for chemical recycling or energy recovery where available
Contaminated Packaging: Rinse and recycle empty containers where permitted; otherwise dispose with normal waste
Special Considerations: Avoid uncontrolled dumping into surface waters and drains
UN Number: Not regulated by DOT, IATA, or IMDG as a hazardous material
Transport Hazard Class: Not classified
Packing Group: Not assigned
Proper Shipping Name: Polyvinyl Alcohol, Modified
Transport Labels: None required
Special Transport Precautions: Protect containers from moisture and rough handling during transit
TSCA Status: All major components listed on the EPA TSCA Inventory
EINECS/ELINCS: Polyvinyl alcohol assigned EINECS number within EU chemicals framework
RoHS/REACH: Does not contain restricted substances; registration not required for major forms
SARA Title III: Not subject to reporting requirements under SARA 302, 304, 313
