First Aid Measures

Inhalation: Move to fresh air; keep at rest in a position comfortable for breathing; seek medical attention if symptoms persist.
Skin Contact: Remove contaminated clothing; wash affected area with soap and water; rinse thoroughly; consult a doctor if irritation appears.
Eye Contact: Rinse cautiously with water for several minutes; remove contact lenses if present; continue rinsing; seek medical attention for persistent symptoms.
Ingestion: Rinse mouth; do not induce vomiting; drink water if conscious; seek immediate medical help.
Important Symptoms: Mild, reversible skin and eye irritation.
Note to Physicians: Treat symptomatically.

Fire-Fighting Measures

Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide, water spray (avoid water jet)
Unsuitable Media: High-pressure water jets may spread the fire
Special Hazards from Combustion: May form carbon monoxide, carbon dioxide, smoke, and other toxic fumes
Protective Equipment: Wear self-contained breathing apparatus and full protective gear
Other Advice: Keep containers cool with water spray to prevent rupture
Explosion Sensitivity: Product does not present a fire or explosion hazard in its typical liquid state

Accidental Release Measures

Personal Precautions: Wear suitable protective clothing, gloves, and eye/face protection
Environmental Precautions: Prevent further leakage or spillage; do not discharge into drains, surface water, or soil
Containment: Dike spill with inert material, such as sand or earth, to prevent spreading
Cleanup Methods: Absorb with inert material; collect and place in properly labeled containers for disposal; wash area with water and detergent
Secondary Hazards: Spills may create slip hazards

Handling and Storage

Handling: Avoid contact with eyes, skin, and clothing; wash thoroughly after handling; use with adequate ventilation; refrain from eating, drinking, or smoking in work area
Storage: Store in tightly closed, clearly labeled containers; keep away from heat, sparks, and open flame; store in cool, dry, and well-ventilated area
Incompatible Materials: Strong oxidizing agents, acids, strong bases
Other Requirements: Protect containers from physical damage
Hygiene Measures: Maintain good industrial hygiene practices; ensure emergency eyewash stations and showers are at hand

Exposure Controls and Personal Protection

Occupational Exposure Limits: No established limits for didecyl adipate
Engineering Controls: Use local exhaust or general dilution ventilation to keep exposures below recommended limits
Personal Protective Equipment:
- Eye/Face Protection: Safety goggles or face shield
- Skin Protection: Impermeable gloves; long-sleeved clothing
- Respiratory Protection: Not needed under normal use conditions; use approved respirator in presence of mist/vapor
- Environmental Protection: Follow best management practices to reduce environmental impact
Other Protective Measures: Ensure eyewash stations and safety showers are nearby

Toxicological Information

Acute Toxicity: Oral LD50 > 5,000 mg/kg (rat); dermal LD50 > 2,000 mg/kg (rabbit)
Inhalation: Low vapor pressure limits inhalation hazard under ambient conditions
Skin Corrosion/Irritation: Non-corrosive; repeated exposure may cause temporary dryness or mild irritation
Eye Damage/Irritation: May cause mild, reversible irritation
Respiratory Sensitization: No evidence of respiratory sensitization
Skin Sensitization: Sensitization not expected
Carcinogenicity: No component listed by IARC, NTP, or OSHA as carcinogenic
Reproductive Toxicity: No data available indicating reproductive risk
Specific Target Organ Toxicity (STOT): Not expected to cause toxicity at typical occupational exposures
Other Effects: Extensive handling can cause defatting of skin; accidental ingestion can result in gastrointestinal upset

Ecological Information

Ecotoxicity: Relatively low acute toxicity to aquatic life (estimated LC50 for fish > 1,000 mg/L)
Persistence and Degradability: Biodegradable with time; generally breaks down under aerobic conditions
Bioaccumulative Potential: High potential for bioaccumulation based on log Kow, but rapid biodegradation limits environmental persistence
Mobility in Soil: Low mobility due to low water solubility and high adsorption to particulates
Other Adverse Effects: Large spills can coat gills of aquatic animals and surface of water bodies, creating oxygen transfer barriers

Disposal Considerations

Waste Disposal: Dispose of in accordance with local, regional, national, and international regulations; incineration preferred for large quantities; avoid uncontrolled releases;
Contaminated Packagings: Containers should be emptied completely and can be recycled after proper cleaning or disposed of as hazardous waste
Special Instructions: Do not allow product or contaminated rinse water to enter drains or watercourses
