Product name: Polyvinylpyrrolidone Common names: Povidone Chemical formula: (C6H9NO)n CAS number: 9003-39-8 Appearance: White to off-white powder or flakes Odor: Slight, characteristic Usage: Thickener, binder, film former across pharmaceutical, cosmetic, and industrial fields
Hazard class: Not classified as hazardous under most international standards Routes of exposure: Inhalation, skin contact, eye contact, ingestion Main health risks: Dust may irritate the respiratory tract and mucous membranes; contact may cause mild eye or skin irritation; ingestion of large quantities could possibly upset the stomach Chronic risks: Prolonged inhalation of dust in industrial settings can contribute to respiratory discomfort Label elements: Not required under OSHA; in workplaces, precautions against dust are generally noted
Main component: Polyvinylpyrrolidone (over 99%) Contaminants: Trace levels of unreacted monomer or solvents may remain from production, but routine quality control keeps impurities minimal Additives: Additives rare, but always consider variations for specialized grades
Eye contact: Flush immediately with plenty of water for several minutes; seek medical attention if irritation persists Skin contact: Wash with soap and water; persistent irritation deserves a doctor visit Inhalation: Move to fresh air if dust inhaled, monitor for coughing or wheezing Ingestion: Rinse mouth, offer water to dilute; for large amounts or symptoms, get medical help
Suitable extinguishing media: Use water spray, CO2, foam, or dry powder Specific hazards: Polyvinylpyrrolidone burns, producing CO, CO2, and other decomposition gases Protective equipment: Firefighters need self-contained breathing apparatus due to risk of toxic gas Fire scene considerations: Dust can form explosive mixtures with air; avoid stirring up dust
Personal precautions: Avoid dust generation; wear approved respirator in case of high exposure Environmental precautions: Prevent entry into drains and water courses by sweeping up or vacuuming without dispersing dust Clean-up methods: Collect mechanically by sweeping or vacuuming with HEPA filter; dispose of according to local waste regulations Spill area ventilation: Increase ventilation to clear dust from the air
Safe handling: Minimize airborne dust by pouring gently, keep containers closed, avoid inhaling powder Personal hygiene: Wash hands after use, avoid eating or smoking when handling material Storage: Store in tightly sealed containers in a cool, dry place, away from sources of ignition and combustible materials Storage incompatibilities: Avoid strong oxidizing agents
Eye protection: Safety glasses or goggles Skin protection: Gloves recommended for long or repeated contact Respiratory protection: Dust mask or respirator for dusty environments Engineering controls: Use local exhaust ventilation to reduce airborne dust Occupational exposure limits: No specific regulatory threshold set, but minimize exposure to airborne particulate Hygiene: Wash thoroughly after handling, change clothes if dust builds up
Physical state: Fine powder, sometimes granular Color: White or light yellow Odor: Mild, specific to product Melting point: Decomposes before melting Solubility: Freely soluble in water, ethanol pH: Slightly acidic to neutral (3–7 in aqueous solution) Molecular weight: Varies by grade, can range from thousands to over a million daltons Density: Roughly 1.2–1.3 g/cm³ Flammability: Dust may form explosive clouds; bulk material is combustible
Stability: Chemically stable under normal conditions Incompatible substances: Strong oxidizers, strong acids Hazardous decomposition: Thermal breakdown releases nitrogen oxides, carbon oxides Reactivity: Not highly reactive, but decomposes under excessive heat Polymerization: No dangerous polymerization reported under typical use
Acute toxicity: Low toxicity, adverse effects rare unless large quantities ingested or dust inhaled over long period Skin irritation: Very mild or none Eye irritation: Possible discomfort, rarely severe Sensitization: No common reports of allergy or sensitization Carcinogenicity: Not classed as carcinogen by IARC, NTP, or OSHA Long-term exposure: No significant effects noted under recommended conditions LD50: Oral rat > 100,000 mg/kg (very low toxicity)
Aquatic toxicity: Not expected to harm aquatic life in normal concentrations Biodegradation: Slowly biodegradable, but breaks down over time in soil and water Bioaccumulation: No bioaccumulation expected due to high solubility Mobility: High in water; can travel with runoff if released in large quantities Persistence: May linger in the environment if released in bulk
Waste treatment: Collect and deliver to local facilities compliant with regional regulation Incineration: Suitable for incineration under controlled conditions Sewage disposal: Avoid putting large amounts into drains or sewage systems Packaging: Clean and reuse or recycle containers, or dispose as general industrial waste Regulatory observation: Follow local guidelines for non-hazardous polymer waste
UN number: None required Classification: Not regulated as dangerous goods by most shipping authorities Packaging group: Not applicable Shipping precautions: Prevent spillage, avoid creating dust during transfer
Global inventory listings: Included in TSCA (US), EINECS (EU), DSL (Canada), and many other national inventories Labeling requirements: Not subject to hazard labeling in most regions, though workplace dust controls apply Worker safety: OSHA workplace standards recommend limiting exposure to nuisance dusts Restrictions: Very few, but always refer to local chemical safety regulations for region-specific rules
