Composition / Information on Ingredients

Chemical Name: Hexa Phenoxy Cyclo Tri-phosphazene   CAS Number: 1184-10-7   Concentration: ≥98% by weight   Impurities: Less than 2%, mostly oligomeric cyclophosphazenes and trace unreacted phenol   Other Components: No hazardous additives, stabilizers, or fillers; pure compound usually supplied as white crystalline powder or flakes

First Aid Measures

Inhalation: Move exposed person to fresh air, loosen tight clothing, if symptoms persist, seek immediate medical attention   Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water, use mild corticosteroid creams for irritation if recommended by a healthcare provider   Eye Contact: Rinse cautiously with water for at least fifteen minutes, remove contact lenses if present and easy to do, get prompt medical help if irritation continues   Ingestion: Do NOT induce vomiting, rinse mouth with water, provide medical observation, monitor for abdominal pain or nausea   Most Important Symptoms: Itchy skin, sneezing, sore throat, watery eyes if exposed to dust

Fire-Fighting Measures

Suitable Extinguishing Media: Use dry chemical, carbon dioxide, foam, or water spray for containment; water jets may scatter powder but control heat   Specific Hazards: Decomposition above 250°C yields toxic phosphorus oxides, phenol fumes may form at high temperatures   Protective Equipment: Full firefighter turnout gear, self-contained breathing apparatus, fire-resistant gloves, goggles   Advice for Firefighters: Approach upwind, cool exposed containers with water spray, avoid runoff into waterways due to solubility of some breakdown products   Combustion Products: Sharp, acrid smoke with possible traces of NOx, POx, and carbon monoxide

Accidental Release Measures

Personal Precautions: Wear dust mask or respirator, impervious gloves, eye protection, non-slip shoes if large amount spills   Environmental Precautions: Do not wash into drains or watercourses, cover spills to minimize airborne dust, inform local authorities for significant releases   Containment Methods: Use sand or inert absorbent for containment, sweep up to prevent spreading   Cleaning Up: Collect with shovel or vacuum designed for solids, avoid using compressed air, seal in puncture-proof containers for disposal   Decontamination: Wash affected area of floor with mild detergent, ventilate space after clean-up

Handling and Storage

Safe Handling Guidelines: Avoid contact with skin or eyes, do not breathe dust, keep work area well-ventilated, handle away from food, beverages, acids, and oxidizers   Storage Recommendations: Store in tightly closed, labeled containers away from moisture or direct sunlight, keep in a cool, dry place between 5–30°C, keep storage area free of incompatible chemicals   Special Packaging: Use lined drums or antistatic bags for large volumes, smaller quantities can go in HDPE bottles with tamper-evident seals   Other Precautions: Have a spill kit and eyewash station nearby, restrict access to trained workers, minimize dust formation during transfer

Exposure Controls and Personal Protection

Exposure Limits: No established occupational limit for this compound, general recommendations based on dust exposure standards (e.g., ACGIH TLV for nuisance dust at 10 mg/m³ total)   Engineering Controls: Local exhaust ventilation, fume extraction, intake hoods at mixing or loading points, sealed transfer systems in production   Personal Protective Equipment: Safety goggles, chemical-resistant gloves (nitrile or neoprene), long pants, work shirt, laboratory coat, N95 or P100 mask if dust present   Hygiene Measures: Wash hands before meals or breaks, launder clothing regularly, avoid touching face during handling   Environmental Controls: Avoid splashes or airborne dust, use containment barriers in production facilities

Physical and Chemical Properties

Appearance: White to off-white crystalline powder or small flakes, faint aromatic odor   Molecular Weight: 693.6 g/mol   Melting Point: 110–118°C   Boiling Point: Decomposes without boiling at standard pressure   Vapor Pressure: Negligible at room temperature   Solubility: Sparingly soluble in water, soluble in acetone, toluene, DMF   pH: Not applicable for solid   Flash Point: Not flammable below 200°C   Auto-ignition Temperature: >400°C   Bulk Density: 0.5–0.7 g/cm3   Viscosity: Not applicable in solid form

Stability and Reactivity

Stability: Chemically stable under recommended storage conditions, no rapid decomposition under ambient conditions   Conditions to Avoid: Excessive heat, open flames, strong UV light, strong acids, and oxidizing agents   Incompatible Materials: Hydrochloric acid, nitric acid, chlorine, peroxides   Decomposition Products: Phenol vapors, phosphorus oxides, nitrogen oxides with thermal breakdown   Polymerization: Does not polymerize spontaneously   Reactivity: May react with strong oxidizers to produce heat or toxic gases

Toxicological Information

Acute Toxicity: Low acute oral and dermal toxicity based on animal tests (LD50 oral: rat > 2500 mg/kg)   Inhalation: Dust may cause temporary respiratory irritation, sneezing, cough, sore throat   Skin Irritation: Repeated contact can cause redness, slight rash in sensitive individuals   Eye Effects: Direct exposure leads to watering, redness, possible stinging   Chronic Exposure Effects: No evidence for carcinogenicity or chronic organ-specific toxicity with normal use   Allergic Reactions: Sensitization unlikely, but dermatitis reported infrequently   Other Risks: Residual phenol impurities increase risk to skin or mucous membranes with large accidental exposures   Mutagenicity: No data for DNA damage; not classified as mutagenic

Ecological Information

Aquatic Toxicity: No measured LC50 but phenoxy phosphazenes persist in water and soil for weeks; low mobility but caution recommended for aquatic environments   Persistence and Degradability: Resists rapid biodegradation, probable slow breakdown into less toxic compounds   Bioaccumulation: Limited due to bulkiness and low water solubility, highly unlikely to build up in fish or wildlife   Soil Mobility: Absorbs to soil and sediments, not expected to migrate to groundwater   Other Effects: High concentration spills may be harmful to invertebrates and plants, report any major environmental release to authorities

Disposal Considerations

Waste Methods: Small amounts can go to licensed chemical waste incinerator, larger loads may need specialist organic disposal   Container Disposal: Triple rinse containers before recycling or disposal, puncture to prevent reuse, follow local hazardous waste codes   Precautions: Avoid mixing with incompatible wastes such as acids, solvents, or bio-waste, do not discharge to sewers or natural waters   Regulatory Requirements: Contact local environmental agency for regulated disposal or incineration   Unused Product: Send back to manufacturer or authorized recycler if possible, store in secure location until picked up for disposal
