Chemical Name: Lauroyl Peroxide
Common Synonym: Dodecanoyl Peroxide
Physical Appearance: Often appears as a white, waxy solid or granular powder
Odor: Faint, waxy scent that may only be noticeable near the material
Uses: Initiator for polymerization, often found in the plastics and resins industries
CAS Number: 105-74-8
Classification: Organic peroxide, unstable, strong oxidizer, hazardous upon contact and in storage
Health Risks: Skin, eye, and respiratory irritation, May cause allergic skin reactions, Harmful if swallowed
Environmental Risks: Toxic to aquatic life with potential for lasting effects
Flammability: High—decomposes explosively under heat or impact, fuels fires much more violently than ordinary combustibles
Main Component: Lauroyl Peroxide; concentration levels typically range between 97-99 percent in pure technical material
Impurities: Small traces of lauric acid, peroxides, and residual solvents from manufacturing
No known added stabilizers
Inhalation: Move the person to fresh air; difficulty breathing requires medical attention
Skin Contact: Rinse skin with plenty of water; contaminated clothing should be removed; seek medical advice for persistent irritation
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes; consult a doctor
Ingestion: Rinse mouth, avoid inducing vomiting, call poison control or a doctor right away
Suitable Extinguishing Media: Water spray, dry chemical, foam; avoid direct streams which can spread material
Unusual Hazards: Decomposition releases flammable gases, possible explosion in confined spaces
Protective Equipment: Full gear including self-contained breathing apparatus is critical; also, firefighters need to keep their distance as exploding containers send dangerous fragments
Special Note: Water alone is not always effective; keep containers cool with water spray to prevent explosion
Personal Protection: Gloves, goggles, and respiratory protection required in case of spills
Spill Response: Prevent dust formation; ventilate the area; cover spill with damp inert material like sand; shovel into well-marked containers
Disposal: Prevent entry into sewers, soil, or waterways; consult an environmental professional for cleanup
Notification: Report large spills to local authorities; monitor for heat and gas buildup in confined areas
Handling: Use only in well-ventilated areas away from heat, sparks, flames, and incompatible substances; avoid shock or friction
Storage: Keep in tightly closed containers, away from sunlight, temperatures above 30°C, and all ignition sources
Segregation: Store away from reducing agents, acids, alkalis, metals, and combustibles to avoid accidental reactions
Labeling: Always label storage areas and containers clearly as containing organic peroxide
Engineering Measures: Proper fume hoods or local exhaust required; avoid open handling in confined or poorly ventilated spots
Personal Protective Equipment: Chemical-resistant gloves, splash-proof goggles, flame-retardant lab coat, and respiratory protection for dusts or vapors
Hygiene: Wash hands thoroughly after handling; no eating, drinking, or smoking where the chemical is used or stored
Exposure Limits: National and industrial safety standards do not always specify airborne limits for this chemical, but sticking to the strictest protocols keeps everyone safer
Appearance: White or slightly off-white granular solid or powder
Odor: Slight, waxy odor
Melting Point: Decomposes above 50°C, often melts and breaks down violently
Boiling Point: Not applicable—decomposition occurs
Solubility: Practically insoluble in water, soluble in organic solvents like chloroform, acetone, and ether
Vapor Pressure: Negligible at room temperature
Density: Around 1.0 g/cm³
Chemical Stability: Sensitive to heat, friction, light, and shock; decomposes rapidly above its active temperature
Incompatible Materials: Strong acids, bases, heavy metals, reducing agents, and combustible materials trigger hazardous reactions
Hazardous Decomposition: Carbon oxides, irritating fumes, and potentially explosive gas release
Polymerization: Normally stable with inhibitors but may run away under poor storage or contamination
Acute Toxicity: May cause skin burns, respiratory distress, eye damage, or gastrointestinal symptoms on exposure
Irritation: Documented as a moderate to severe irritant to skin and mucous membranes
Sensitization: Repeated contact sometimes leads to allergic skin reactions
Long-Term Risks: Chronic exposure data is limited, but organic peroxides show no evidence of wide-scale carcinogenic or reproductive risks in available literature
Toxicity: Proves toxic in aquatic environments, with documented effects on fish and invertebrate populations
Degradation: Breaks down fairly rapidly in water and soil, especially when exposed to light and microbes
Persistence: Doesn’t bioaccumulate, but decomposition products may still pose risks downstream
Waste Handling: Collect and seal in specialized hazardous waste containers; do not incinerate in open flames
Disposal Methods: Work with licensed hazardous waste handlers; do not pour down drains or landfill directly
Environmental Precautions: Prevent loss to soil, water, or air; manage all cleanup debris as hazardous material
UN Number: 3106 for organic peroxides, solid, type D (Lauroyl Peroxide falls here)
Transport Class: 5.2 (Organic Peroxide)
Packaging: Rigid, shatterproof, and labeled containers required
Special Transport Notes: Always separate from food, feed, combustibles, and strong acids or bases in transit; vehicles must allow for temperature control
Health and Safety Regulations: Occupational exposure standards may guide permissible handling in workplaces; listed under organic peroxides by national chemical safety agencies including OSHA and the European Chemicals Agency
Environmental Regulations: Inclusion in chemical inventory lists like TSCA and REACH means tracking, reporting, and risk management requirements apply
Hazard Communication: Labels and safety training necessary wherever use or storage takes place; SDS documentation must always be available for reference on-site
