Inhalation: Remove to fresh air if aerosols or mists are inhaled; seek medical attention if coughing or irritation persists
Skin Contact: Wash exposed skin with soap and water; seek advice if redness or irritation develops
Eye Contact: Rinse thoroughly with plenty of water for several minutes; remove contact lenses if present and easy to do, continue rinsing; contact a physician if irritation persists
Ingestion: Rinse mouth out with water, do not induce vomiting, seek medical advice if feeling unwell
Most Important Symptoms: Mild irritation is rare but may include redness or itchiness with direct contact or accidental exposure
Advice for Medical Personnel: Treat symptomatically; no specific antidote known for this substance
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, foam, or water spray
Unsuitable Media: Direct water jet may spread material
Fire Hazard Characteristics: Burns with moderate smoke and potentially irritating fumes; may release carbon oxides (CO, CO2) when burned
Protective Equipment for Firefighters: Wear full protective gear, including self-contained breathing apparatus
Special Procedures: Move containers from area if safe to do so; use water spray to cool surrounding containers exposed to fire
Personal Precautions: Avoid direct contact with spilled material; use gloves and safety glasses in bulk situations; beware of slip hazards
Environmental Precautions: Prevent entry to drains or surface waters; dike large spills with inert material to minimize environmental movement
Clean-Up Methods: Use inert absorbent materials such as sand or earth; shovel into labeled containers for eventual disposal
Further Handling: Clean spill area thoroughly to remove residue; ventilate affected area if indoors
Safe Handling: Use local ventilation for large scale processes; avoid inhaling any mist or vapors generated during heating
Hygiene Measures: Wash hands after handling; avoid eating, drinking, or smoking in workplaces handling large volumes
Storage Conditions: Keep container tightly closed; store in cool, dry, well-ventilated area away from sources of ignition or heat
Incompatible Materials: Strong oxidizing agents
Packaging Materials: Use suitable containers made of HDPE or steel resistant to oils or fatty esters; keep out of direct sunlight
Occupational Exposure Limits: No established limits for this material
Engineering Controls: Use process enclosures and local exhaust as appropriate; minimize aerosol generation
Personal Protective Equipment:
Skin: Use gloves resistant to fatty materials when handling bulk quantities
Eyes: Safety glasses or goggles for bulk handling
Respiratory: Respirator only needed in case of persistent mist or aerosol generation, generally not required in normal use
Personal Hygiene: Thoroughly wash hands and affected skin before breaks and at end of workday
Appearance: Clear to pale yellow viscous liquid at room temperature
Odor: Mild, fatty, slightly waxy
pH: Not applicable (non-aqueous)
Melting Point: Approximately 12°C
Boiling Point: Decomposes before boiling
Flash Point: >200°C (closed cup)
Evaporation Rate: Negligible
Flammability: Not classified as flammable, but combustible at high temperature
Vapor Pressure: <0.01 mmHg at 20°C
Vapor Density: No data available
Relative Density: 0.88-0.89 g/cm³ at 20°C
Solubility in Water: Insoluble
Solubility in Other Solvents: Soluble in ethanol, most oils, and organic solvents
Partition Coefficient (n-octanol/water): High (log Kow >5, estimated)
Auto-Ignition Temperature: >300°C
Decomposition Temperature: Above 200°C, with degradation
Chemical Stability: Stable under recommended storage and normal use conditions
Reactivity: Not reactive under normal working conditions
Possible Hazardous Reactions: Reacts with strong oxidizing agents
Conditions to Avoid: Excess heat, open flame, oxidizing conditions
Incompatible Materials: Strong oxidants like peroxides and chromates
Hazardous Decomposition Products: Thermal decomposition produces carbon dioxide and carbon monoxide
Acute Toxicity: Low acute oral, dermal, and inhalation toxicity expected; estimated LD50 (oral, rat) > 5000 mg/kg based on similar esters
Skin Irritation: Minimal irritation potential based on structure and available data
Eye Irritation: Mild transient irritation possible on contact
Respiratory Sensitization: Not expected to cause sensitization
Chronic Toxicity: No long-term carcinogenicity, mutagenicity, or reproductive effects recorded in available studies
Other Effects: Not a skin sensitizer, not classified as reproductive toxin
Ecotoxicity: Not acutely toxic to aquatic life in typical use concentrations; high hydrophobicity means bioaccumulation is theoretically possible but degradation is expected in natural environments
Persistence and Degradability: Biodegradable by standard methods over time; large accumulations in soil or water not likely due to low water solubility
Bioaccumulative Potential: May accumulate, partitioning to sediments but expected to degrade with microbial action
Mobility in Soil: Low mobility due to insolubility in water
Other Adverse Effects: Avoid bulk release to environment to minimize impact to aquatic and terrestrial habitats
Waste Treatment Methods: Dispose of material according to local regulations and approved waste handler procedures
Disposal of Packaging: Empty containers can hold product residue, follow appropriate cleaning or disposal; recycling may be possible with proper rinsing
Special Precautions: Avoid incineration except in controlled facilities; do not discharge to sewers or open water
UN Number: Not regulated for transport under most international carriage rules (ADR, IATA, IMDG)
Proper Shipping Name: Not regulated
Transport Hazard Class: Non-hazardous
Packing Group: Not assigned
Environmental Hazards: Not a marine pollutant
Special Precautions for User: Handle in accordance with good industrial hygiene and safety practice during transport and transfer of bulk quantities
International Chemical Inventory: Listed on US TSCA, EU REACH, Canadian DSL, Japanese ENCS
Regulatory Status: Not subject to special restrictions under current global chemical safety laws
Labeling Requirements: No special hazard labels required under GHS
Other Regulatory Considerations: Used widely in cosmetics and personal care with no significant ingredient bans; must comply with general manufacturing purity and consumer safety standards
