Signal Word: Danger
Hazard Statements: May cause fire, yields oxygen, causes skin/eye irritation, may cause respiratory irritation
Pictograms: Flame over circle, exclamation mark
Precautionary Statements: Keep away from heat/sparks/open flames, use non-sparking tools, avoid breathing dust, wash exposed skin thoroughly
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Target Organs: Skin, eyes, respiratory system
Chronic Effects: Extended exposure can lead to dermatitis or respiratory sensitization
Bis(Peroxydodecanedioic Acid): ≤ 42%
Sodium Sulfate: ≥ 56%
Stabilizers: Minor proprietary stabilizers, amounts below hazardous thresholds
Impurities: Trace amounts of organic reactants and side products
Inhalation: Remove victim to fresh air at once, monitor breathing, seek medical help if symptoms persist
Skin Contact: Rinse affected skin with plenty of water for at least 15 minutes, remove contaminated clothing, seek attention for irritation
Eye Contact: Flush with running water for at least 15 minutes while holding eyelids open, do not rub, consult medical professional
Ingestion: Do not induce vomiting, rinse mouth with water, get immediate medical attention
Delayed Effects: Watch for possible breathing discomfort or delayed hypersensitivity
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, do not use foam
Specific Hazards: Strong oxidizer, releases oxygen, may enhance other fires, decomposition can generate toxic fumes like carbon oxides and sulfur oxides
Protective Equipment for Firefighters: Full SCBA gear, chemical-resistant suit
Firefighting Procedures: Approach from upwind, cool containers with water, remove spills from fire area
Explosion Risk: Peroxides may decompose explosively with heat or contamination
Personal Precautions: Evacuate spill area, wear goggles, gloves, and respiratory protection
Environmental Precautions: Avoid release to drains, prevent soil and water contamination
Methods for Clean-Up: Use clean non-sparking tools to scoop material into dry containers, avoid creating dust, flush residual with large water amounts
Special Procedures: Contain leaks, notify emergency response if large quantity spills or environmental release occurs
Safe Handling: Keep container closed and dry, handle away from acids, reducing agents, combustibles, avoid shock and friction
Personal Hygiene: Wash hands after handling, keep work clothes separated, minimize bare-skin contact
Storage: Store in original container below 25°C (77°F), away from heat, direct sunlight, incompatible materials
Incompatibles: Organic materials, strong acids/bases, amines, heavy metals, flammable substances
Storage Area Features: Well-ventilated, temperature-controlled, segregated from foods and feeds
Exposure Limits: No OSHA or ACGIH limits for compounds; treat as nuisance dust or oxidizer
Engineering Controls: Local exhaust ventilation, wet handling to reduce airborne dust
Personal Protection Equipment: Chemical-resistant gloves, goggles, long-sleeve apron or coveralls, dust mask or NIOSH-approved respirator for dusty conditions
Workplace Hygiene: Clean workspaces often, do not eat/drink/smoke near material, launder protective clothing
Appearance: Granular or powder, off-white color
Odor: Slight, non-offensive
pH (1% solution): 5–7
Melting Point: About 110°C (for pure peracid), blend decomposes before melting
Boiling Point: Not applicable, decomposes
Flash Point: Not flammable, but accelerates burning of other substances
Solubility: Water solubility varies, sodium sulfate is soluble, peracid weakly soluble
Decomposition Temperature: Above 60°C, increases hazard of rapid breakdown
Vapor Pressure: Negligible at room temperature
Bulk Density: 500–900 kg/m³
Chemical Stability: Stable under recommended conditions, decomposes with heat, sunlight, or contamination
Conditions to Avoid: Temperatures above 25°C, friction, shock, exposure to acids, bases, organic material
Incompatible Materials: Strong reducing agents, heavy metals, flammable materials
Hazardous Decomposition Products: Carbon oxides, sulfur oxides, possible peracids, oxygen gas
Hazardous Polymerization: Does not occur under correct storage
Likely Routes of Exposure: Eyes, skin, inhalation, ingestion
Acute Effects: Skin and eye irritation, possible burns, respiratory discomfort
Chronic Effects: Repeated contact may cause skin dryness, eczema, coughing
LD50 (oral, rat): Data limited, estimated >2,000 mg/kg for mixture
Irritation/Corrosivity: Causes moderate to severe irritation to mucous membranes
Sensitization: No confirmed data, but peroxides may induce allergic reaction in sensitive individuals
Carcinogenicity: Not listed by IARC, NTP, or OSHA
Environmental Data: Not persistent in environment, peracid breaks down to organic acids, sodium sulfate is naturally occurring
Aquatic Toxicity: High concentrations can harm aquatic organisms due to oxidizing action
Bioaccumulation: Unlikely, rapid breakdown in media
Mobility: Sulfate highly mobile in water, peracid less so
Other Ecotoxic Effects: Overdosing in waterways can lead to temporary oxygen depletion affecting aquatic life
Waste Treatment Methods: Incineration under controlled conditions (with approval), do not landfill reactive material
