Chemical Name: 4-Hexylresorcinol
Concentration: ≥98%
Chemical Family: Alkylresorcinols
Impurities/Additives: May contain trace process chemicals from manufacturing, typically below 1%
Inhalation: Move exposed individual to fresh air, keep at rest, monitor for respiratory distress, seek medical help if symptoms develop or persist
Skin Contact: Remove contaminated clothing, wash affected skin thoroughly with water and mild soap, monitor for irritation, seek medical care for persistent redness or rash
Eye Contact: Promptly rinse eyes with water for at least 15 minutes, lift eyelids occasionally, remove contact lenses if present, consult ophthalmologist for severe irritation
Ingestion: Rinse mouth with water if conscious, do not induce vomiting, consult health provider immediately if more than a small quantity consumed or symptoms appear
Suitable Extinguishing Media: Water spray, dry chemical, foam, or carbon dioxide
Fire Hazards: Emits toxic fumes including carbon monoxide and carbon dioxide in fire conditions, combustible dust may form
Protective Equipment: Firefighting personnel wear full turnout gear and approved self-contained breathing apparatus
Special Procedures: Cool containers with water spray, move containers from fire area if safe, avoid inhalation of combustion products
Personal Precautions: Use appropriate PPE including gloves, goggles, dust mask
Environmental Precautions: Prevent release into drains, surface waters, or soil; inform authorities if significant spill occurs
Spill Clean-Up: Sweep up and collect spilled material without raising dust, place in labeled container, wash area with water, ventilate space
Handling: Avoid dust generation and accumulation, refrain from breathing dust, wash hands before eating or drinking, keep away from incompatible materials—strong oxidizers and acids
Storage: Keep container tightly closed in a dry, cool, and well-ventilated place, minimize moisture exposure, store away from strong oxidizing agents, segregate from food and feedstuffs, label containers properly
Engineering Controls: Use efficient local exhaust ventilation, maintain proper air exchange; explosion-proof equipment for dust-prone environments
Personal Protective Equipment: Gloves resistant to chemical penetration, safety goggles with side protection, dust mask or respirator when airborne particles present, lab coat or coveralls
Hygiene Measures: Remove contaminated clothing before eating, smoking, or leaving work area; wash hands, arms, and face thoroughly at end of shift
Occupational Exposure Limits: Not established specifically for 4-Hexylresorcinol; recommend general nuisance dust threshold limits (10 mg/m³ total dust, 3 mg/m³ respirable)
Appearance: Pale yellow to white crystalline solid
Odor: Faint phenolic
pH: Not applicable (solid)
Melting Point: 66–69°C
Boiling Point: Decomposes before boiling
Flash Point: Above 130°C (closed cup)
Solubility: Slightly soluble in water, highly soluble in ethanol, ether, and organic solvents
Partition Coefficient (log Kow): ~3.3
Relative Density: ~1.04 g/cm³
Vapor Pressure: Very low at ambient temperature
Other: Stable in normal conditions, slow degradation under strong UV or oxidizing chemicals
Chemical Stability: Stable at room temperature and pressure, does not decompose in typical storage
Reactivity: May react with strong oxidizing agents; avoid strong acids or bases
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, potential irritant organic vapors
Incompatible Materials: Strong acids, oxidizers, halogenating agents
Hazardous Polymerization: Does not occur under normal conditions
Likely Routes of Exposure: Inhalation, skin, eyes, mouth
Acute Toxicity: Estimated oral rat LD50 ranges from 400-800 mg/kg; skin absorption not thoroughly documented, mild irritant tendency
Skin Corrosion/Irritation: Irritation on repeated or prolonged contact, possible allergic response
Eye Damage/Irritation: Immediate eye stinging, possible persistent redness or watering
Respiratory Sensitivity: Breathing dust may cause cough, throat irritation, mild bronchospasm in sensitive individuals
Chronic Effects: Data limited, prolonged exposure can lead to dermatitis; not listed as a carcinogen or mutagen by NTP, IARC, or OSHA
Aspiration Hazard: Low due to low volatility
Aquatic Toxicity: Harmful to aquatic life in moderate concentrations (acute EC50 for daphnia & algae: 1–10 mg/L)
Persistence and Degradability: Expected to degrade slowly—partial breakdown in soil driven by microbial activity, low hydrolysis in water
Bioaccumulation Potential: Log Kow suggests potential for moderate bioaccumulation
Mobility in Soil and Water: Limited movement in soil, leaching not expected under proper use
Other Environmental Effects: Toxic in large persistent spills to aquatic environments—remediation actions advised for significant release
Product Disposal: Small amounts, if uncontaminated, may be disposed with household waste in many areas; larger quantities require incineration or chemical landfill approved for organic chemicals
Contaminated Packaging: Clean containers can be recycled or disposed per local guidelines; containers not to be reused unless decontaminated
Sewage Disposal: Avoid discharge to municipal wastewater, will disrupt biological treatment efficiency at significant concentrations
UN Number: Not regulated as hazardous for transport
Transport Hazards Class: Not listed under ADR, IATA, IMDG hazardous goods
Packing Group: No classification
Special Precautions: Protect from moisture and physical damage during transport, check for leaks before shipment, routine documentation per standard chemical best practices
Workplace Classification: Not specifically regulated by OSHA as a hazardous chemical, treated as hazardous by good laboratory standards
