Chemical Name: Nonylphenol
Synonyms: 4-Nonylphenol, p-Nonylphenol
Concentration: ≥ 95% by weight
Impurities: Trace amounts of related alkylphenols, water (≤ 1%)
Inhalation: Move to fresh air. If breathing becomes difficult, seek medical attention. Remove from exposure, monitor for respiratory distress.
Skin Contact: Remove contaminated clothing. Wash affected skin thoroughly with soap and water. If irritation develops and persists, consult a healthcare professional.
Eye Contact: Rinse eyes gently with plenty of water for several minutes. Remove contact lenses if easy to do. Continue rinsing. Get medical advice if irritation occurs.
Ingestion: Rinse mouth. Do not induce vomiting. Drink water if conscious. Call poison control or seek immediate medical help if symptoms appear.
Suitable Extinguishing Media: Use dry chemical, CO2, foam, or water spray.
Unsuitable Extinguishing Media: Direct water stream may scatter liquid, risk of fire spread.
Specific Hazards: Combustion produces carbon monoxide, carbon dioxide, toxic organic vapors.
Protective Equipment: Wear self-contained breathing apparatus and full protective gear.
Additional Advice: Keep containers cool by spraying with water to prevent rupture.
Personal Precautions: Evacuate area if necessary. Wear appropriate gloves, goggles, and chemical resistant clothing. Ventilate area to avoid vapor buildup.
Environmental Precautions: Prevent entry into soil, ditches, sewers, waterways. Nonylphenol can cause irreversible damage to aquatic systems.
Methods for Cleanup: Use absorbent materials such as sand or vermiculite. Shovel into approved chemical waste containers. Wash spill site with plenty of water but prevent runoff into natural water bodies.
Handling: Wear gloves, goggles, and protective clothing. Use chemically resistant containers and equipment. Avoid creating aerosols or breathing vapors. Practice good industrial hygiene.
Storage Conditions: Store tightly closed in cool, dry, well-ventilated area away from heat, sparks, open flames, alkaline substances, and strong oxidizers. Keep away from foodstuffs and animal feed.
Incompatible Materials: Strong acids, oxidizing agents, bases
Engineering Controls: Use local exhaust ventilation to minimize vapor exposure. Work outdoors or in a chemical fume hood when possible.
Exposure Limits: No established OSHA or ACGIH exposure limits exist for nonylphenol; minimize exposure based on risk assessments and regulations.
Personal Protective Equipment: Wear chemical-resistant gloves (nitrile recommended), safety goggles or face shield, long-sleeved clothing, and, for large-scale use, respiratory protection such as an organic vapor respirator.
Hygiene Measures: Wash hands thoroughly after handling. Remove and wash contaminated clothing before reuse.

LD50 (oral, rat): Approximately 580 mg/kg
Carcinogenicity: Not classified by IARC, NTP, or OSHA as a known human carcinogen.
Other Risks: Prolonged or repeated exposure can cause dermatitis.
Ecotoxicity: Highly toxic to aquatic organisms, causes long-term adverse effects in the aquatic environment.
Bioaccumulation: Tends to bioaccumulate in aquatic organisms; significant concentrations found in fish tissue.
Degradability: Slowly biodegradable in water and soil; persistent in sediments.
Mobility in Soil: Potential for limited mobility; adsorbs strongly to sediment and organic matter.
Waste Disposal Method: Incinerate or dispose at approved hazardous waste facilities; follow all local, state, and federal requirements.
Disposal of Contaminated Packaging: Rinse containers, then send for industrial disposal or recycling as hazardous waste.
Precautions: Avoid release to environment during disposal; do not flush to sewer.
