Additives: No known hazardous stabilizers or preservatives in the pure material
Other Identifiers: RTECS Number QU2450000, EINECS 200-470-9
Inhalation: Move person to fresh air, seek medical attention if symptoms persist
Skin Contact: Wash with soap and water, remove contaminated clothing, seek medical attention if irritation develops
Eye Contact: Rinse immediately with plenty of clean running water for at least 15 minutes, keep eyelids open, consult eye specialist if irritation occurs
Ingestion: Rinse mouth, do not induce vomiting, seek medical help if feeling unwell
Note to Physician: Symptomatic treatment as there are no specific antidotes
Suitable Extinguishing Media: Dry chemical, foam, CO2, water spray in case of large fire
Specific Hazards: Combustion may yield noxious fumes including carbon monoxide, carbon dioxide, acrolein
Special Protective Equipment for Firefighters: Self-contained breathing apparatus, full protective gear
Explosion Risk: Not explosive, but heated vapors could ignite with strong ignition source
Hazardous Combustion Products: Thermal breakdown can release irritating and toxic gases
Fire Fighting Instructions: Cool fire-exposed containers with water spray to prevent rupture
Personal Precautions: Wear gloves, goggles, protective clothing, avoid breathing mist
Environmental Precautions: Prevent release into soil and local waterways, contain spilled material
Cleanup Methods: Absorb spillage using sand, earth, or inert absorbent, collect in lidded container for disposal
Decontamination: Clean spill area with soap and water after pickup
Disposal: Dispose waste in accordance with local, state, and federal regulations
Handling: Handle with good ventilation, wear recommended personal protection, avoid static discharge
Safe Storage Requirements: Keep tightly closed in original container, store in cool, dry, and well-ventilated area away from direct sunlight and heat sources
Storage Temperature: Preferably below 25°C
Incompatible Materials: Strong oxidizers, strong acids and bases
Hygiene Practices: Wash hands after use, keep work area clean, prevent food and drink exposure
Bulk Storage: Use stainless steel or glass for storage facilities, avoid long exposure to moisture or high temperature to minimize product degradation
Exposure Limits: No OSHA, ACGIH or NIOSH exposure limits set for linoleic acid

Materials to Avoid: Strong acids, alkalis, oxidizers
Decomposition Products: Carbon monoxide, carbon dioxide, aldehydes from thermal decomposition
Acute Toxicity: LD50 (oral/rat): >5,000 mg/kg (low toxicity)
Skin Irritation: Mildly irritating on prolonged exposure
Eye Irritation: May cause temporary mild irritation
Respiratory Effects: Inhalation of mist or spray may irritate airways
Chronic Exposure: No reported long-term adverse health effects at normal exposures
Carcinogenicity: No evidence of carcinogenic potential
Mutagenicity/Teratogenicity: Not expected to be mutagenic, not shown teratogenic in animal studies
Sensitization: Not classified as a skin sensitizer
Ecotoxicity: Expected to be low toxicity to aquatic species due to low solubility
Persistence and Degradability: Biodegradable, breaks down in soil and water through microbiological processes
Bioaccumulative Potential: High log Kow signals potential for bioaccumulation, but rapid biodegradation reduces long-term risk
Mobility in Soil: Strong adsorption limits mobility; runoff under heavy spill possible
Other Hazards: Large releases may contribute to oxygen demand in natural environments and affect aquatic life
Waste Disposal Methods: Dispose of unused product/sweepings according to local, national, and international regulations; preferred disposal by incineration
