Spill Cleanup Methods: Collect spilled material with dry inert absorbent and place in properly labeled containers for disposal. Wash area with plenty of water and ventilate.
Decontamination: Use detergent and water to thoroughly clean contaminated surfaces.
Disposal: Refer to waste disposal section for guidance.
Handling: Wear suitable protection against contact with eyes, skin, and clothing. Keep container closed. Work in a well-ventilated area. Avoid inhalation of dust or vapor. Do not eat, drink, or smoke while handling material.
Storage: Store in cool, dry, and well-ventilated place. Keep away from incompatible materials, such as strong oxidizers and acids. Keep container tightly sealed. Avoid storing near heat or open flame. Maintain good housekeeping to minimize contamination and spills.
Packaging Materials: Use containers made of compatible material such as polyethylene or glass.
Occupational Exposure Limits: No specific exposure limits established for this compound.
Engineering Controls: Use local exhaust ventilation or general room ventilation to maintain airborne levels below recommended exposure limits.
Personal Protective Equipment: Use chemical-resistant gloves, safety goggles, and appropriate clothing. In case of insufficient ventilation, wear an approved respirator.
Hygiene Measures: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Do not allow contact with food or beverages.
Monitoring: Regular workplace monitoring not typically required unless large volumes handled or dusts generated.
Appearance: White to pale yellow solid or wax, characteristic odor
Molecular Weight: 288.95 g/mol
Melting Point: 28–34°C
Boiling Point: 358°C at 101.3 kPa
Solubility: Insoluble in water, soluble in most organic solvents such as chloroform, ether, and hexane
Density: 0.85 g/cm³
Vapor Pressure: Negligible at 20°C
pH: Not applicable (does not form aqueous solution)
Flash Point: >150°C
Autoignition Temperature: Not established
Explosive Properties: Not explosive
Partition Coefficient (log Kow): High, indicates potential for bioaccumulation
Chemical Stability: Stable under recommended storage conditions.
Hazardous Reactions: Will not polymerize or undergo violent reactions under normal conditions.
Incompatible Materials: Strong oxidizing agents, strong acids, bases
Decomposition Products: Hydrogen chloride, chlorine-containing compounds, carbon oxides on combustion
Conditions to Avoid: Exposure to flames, high temperatures, incompatibles
Acute Toxicity: Data on 1-chlorooctadecane is limited; no significant acute oral, dermal, or inhalation toxicity reported in available studies.
Skin Irritation: May cause mild irritation after prolonged contact.
Eye Irritation: May cause temporary discomfort and redness.
Respiratory Sensitization: Dusts or vapors may cause irritation with repeated or extended exposure.
Chronic Effects: No evidence of carcinogenicity, mutagenicity, reproductive, or developmental toxicity found in standard reference sources.
Target Organs: No known specific target organs identified for this substance.
Symptoms: Redness, discomfort, mild itching or irritation of skin and mucous membranes if exposed
Ecotoxicity: Fish, invertebrate and algae toxicity data limited. Likely low acute toxicity due to low solubility in water.
Persistence and Degradability: Slow degradation anticipated in soil and sediment, due to long alkyl chain; not readily biodegradable.
Bioaccumulation Potential: High log Kow value suggests potential for accumulation in aquatic organisms.
Mobility in Soil: Strong adsorption to soil particles expected; unlikely to leach into groundwater.
Aquatic Environmental Fate: Insoluble; likely to partition to sediment rather than remain in water column.
Waste Disposal Methods: Dispose of in accordance with local, regional, and national regulations. Incineration in approved facility recommended. Do not discharge untreated material into water bodies or municipal sewers.
Waste Packaging: Contaminated containers must be emptied and disposed of or reused in compliance with relevant laws.
Special Considerations: Do not attempt to incinerate in unapproved facility. Residues and spillage require appropriate cleanup methods to prevent environmental release.
RCRA Code: Not classified under US EPA hazardous waste codes.
UN Number: Not regulated as hazardous for transport under IMDG, IATA, ADR, or USDOT.
