Chemical Name: Isopropylated Triphenyl Phosphate
Common Names: IPPP, IPPP50
Use Cases: Plasticizer in PVC and polymers, flame retardant in electronics, fluid in hydraulic systems
Physical State: Clear, viscous liquid with faint aromatic odor, slightly oily feel
Key Identifiers: Water-insoluble, colorless to light yellow
Odor Threshold: Pleasant, hard to detect in open environments, can build up in closed rooms
Flammability: Can burn if exposed to open flame or high heat
Exposure Routes: Inhalation, skin contact, eye exposure, accidental ingestion
Health Effects: Headaches, breathing irritation, skin redness, eye discomfort, nausea in higher doses
Chronic Risks: Prolonged exposure can affect nervous system; some testing hints at liver and kidney impacts
Environmental Risks: Persistent in the environment, builds up in sediment, harmful to fish and aquatic invertebrates
Signal Words: Warning due to chronic risks and aquatic toxicity
Main Ingredient: Isopropylated Triphenyl Phosphate, typically 50-60 percent isopropyl content
Minor Components: Triphenyl phosphate and partially isopropylated derivatives
Impurities: Trace unreacted raw materials, potential manufacturing byproducts under 1 percent
Inhalation: Move affected individual to fresh air, watch for difficulty breathing or coughing, seek medical care for strong symptoms
Skin Contact: Wash hands or exposed area with plenty of soap and water, remove contaminated clothing
Eye Contact: Rinse carefully for up to 15 minutes with clean water, avoid rubbing, get checked if irritation lingers
Ingestion: Rinse mouth, do not force vomiting, look for nausea or trouble swallowing, call medical help if symptoms persist
Fire Risk: Flammable at high temperature, fumes can build up in closed storage
Suitable Extinguishing Media: Carbon dioxide, foam, dry chemical powder
Hazardous Combustion Products: Toxic phosphorus oxides, irritating smoke when burned
Protective Equipment for Firefighters: Wear full gear with breathing protection, keep upwind if responding to warehouse fires
Personal Precautions: Shield skin, wear gloves, use goggles, keep area ventilated
Containment: Prevent liquid spills from reaching drains or streams, use absorbent material like sand
Cleanup: Collect absorbed material in sturdy containers, dispose as chemical waste, wash area with detergent and water
Safe Handling Tips: Avoid direct contact, keep capped, work with in ventilated areas, don’t eat or drink near product
Storage Guides: Store in cool, dry, well-ventilated spaces, away from heat and ignition sources
Compatibility: Avoid mixing with strong acids or oxidizers, separate from food or feed stocks
Inventory Controls: Rotate stock, use older batches first to limit long-term storage complications
Recommended Exposure Limits: No strict OSHA standard; minimize repeated or lengthy exposure
Engineering Controls: Use fume hoods, local exhaust fans, open windows
Personal Protective Equipment: Nitrile gloves, splash goggles, protective aprons, mask or respirator for large spills or poor ventilation
Hygiene Practices: Wash hands after handling, don’t touch face or eyes, change out of work clothes after shift
Appearance: Colorless to pale yellow, viscous oil
Odor: Mild, aromatic
Solubility: Insoluble in water, dissolves in most organic solvents
Boiling Point: Above 350°C
Melting Point: Below -50°C, remains liquid at low temperatures
Vapor Pressure: Very low at room temperature
Density: About 1.16 to 1.20 g/cm³
Viscosity: High, slow-pouring
Chemical Stability: Stable for years in sealed drums away from moisture
Conditions to Avoid: Open flames, prolonged ultraviolet exposure, strong oxidizers
Hazardous Decomposition: Breaks down into phosphoric acid fumes and carbon oxides at high heat or flame
Incompatibility: Strong acids, bases, oxidants
Polymerization: Does not self-polymerize
Likely Health Effects: Short-term exposure can trigger mild irritation, headaches, or upset stomach; eyes are more sensitive
Long-term Outcomes: Lab animal studies show signs of liver and nerve impact at high or repeat exposures, evidence still debated by experts
Carcinogenicity: Not regulated as cancer-causing, still called out for further research by regulators
Sensitization: No clear sign of allergy risk, caution still advised for sensitive workers
Persistence: Chemically stable in soil and water, does not break down quickly
Bioaccumulation: Buildup over time in sediment and aquatic wildlife
Aquatic Toxicity: Toxic to fish and invertebrates, especially at high concentration
Mobility: Tends to bind to soil and suspended matter, less likely to leach, can travel far in waterways attached to particles
Preferred Methods: Controlled incineration at approved facilities, never dump down drains
Container Disposal: Triple rinse or puncture before landfill, follow hazardous waste codes
Alternative Methods: Consult local waste authorities for take-back programs in large quantities
Transport Class: Not usually restricted for small shipments, larger bulk lots may need labeling for hazardous substances
Special Precautions: Use sealed drums, check for leaks or residue on outer surfaces before shipment
Compatibility: Ship separate from strong acids or oxidizers, avoid mixing loads with food or animal feed
Safety Practices: Notify receiving facilities ahead of time, handle only with trained staff
Regulation Status: Listed under priority pollutant registers for aquatic impacts in several countries
Use Restrictions: European and some Asian regulations restrict or monitor use in products likely to contact food or the public
Worker Rights: Facilities expected to share chemical safety data and train staff on responsible handling
Reporting Requirements: Significant spills or environmental releases must be reported to state or national authorities, especially near water bodies
Ongoing Updates: Laws around flame retardants and plasticizers change as new science and public concern drive reforms
