Chemical Name: Isobutyl Methyl Ketone Common Names: 4-Methyl-2-pentanone, Hexone CAS Number: 108-10-1 Molecular Formula: C6H12O Appearance: Colorless liquid with a characteristic odor Use Cases: Employed in paints, coatings, adhesives, and some industrial cleaning applications
Main Risks: Flammable liquid and vapor, causes irritation to eyes and respiratory system, possible long-term effects with chronic exposure Acute Symptoms: Dizziness, headache, drowsiness, nausea, eye and throat irritation Chronic Exposure: Prolonged or repeated contact irritates the skin, vapors over time damage liver and kidneys Fire Hazards: Vapors form explosive mixtures with air; ignition source can trigger a flash fire Regulatory Classification: Flammable (GHS Category 2); Irritant; Harmful
Main Ingredient: Isobutyl Methyl Ketone (100%) Purity: Generally available in concentrations above 98% Impurities: Trace amounts of related ketones or residual solvents rarely exceed 1%
Inhalation: Remove the person to fresh air without delay. Give oxygen if breathing stays difficult. Seek medical attention for persistent symptoms or if exposure was significant. Skin Contact: Wash affected area thoroughly with soap and water. Remove contaminated clothing promptly. Skin irritation should prompt a medical check. Eye Contact: Rinse eyes immediately with running water for at least 15 minutes, holding eyelids open. Seek medical attention for pain or vision changes. Ingestion: Rinse mouth with water. Don’t induce vomiting unless instructed by a professional. Get medical evaluation swiftly, making the chemical clear to responders.
Suitable Extinguishing Methods: Dry chemical, carbon dioxide, or alcohol-resistant foam. Use water spray to cool surrounding containers but avoid using water jets directly on the burning liquid, as that spreads fire Specific Hazards: Vapors travel to distant ignition sources and flash back; combustion releases carbon monoxide and carbon dioxide Protective Equipment: Firefighters should don self-contained breathing apparatus and full protective gear to keep vapors and combustion products out of their respiratory system Special Precautions: Evacuate area if fire cannot be quickly controlled, and keep upwind of fire and vapors
Precautions: Evacuate personnel from the leak area. Remove all sources of ignition, including open flames, sparks, and equipment that can generate static electricity Personal Protection: Wear chemical-resistant gloves, goggles, and suitable respirators when tackling spills Cleanup Approach: Contain spill using non-combustible absorbents such as sand or earth, then collect residues in sealed metal containers for safe disposal Ventilation: Ensure strong airflow to prevent vapor buildup
Safe Handling Advice: Transfer with care to avoid spills and vapor release. Don’t smoke or use open flames near the area Storage Conditions: Keep containers in cool, dry, well-ventilated locations away from sources of heat or ignition. Store separately from strong oxidizers, acids, or bases Container Requirements: Use tightly sealed metal or chemically compatible plastic containers, never leaking or rusted Workplace Practices: Label storage clearly, restrict access to trained staff, and keep eye wash stations and showers nearby
Occupational Exposure Limits: OSHA and ACGIH recommend exposure limits around 50 ppm (parts per million) as an 8-hour time-weighted average Ventilation: Use local exhaust ventilation or process enclosures to capture vapors at the source Personal Protective Equipment: Chemical splash goggles and face shields protect the eyes, nitrile gloves or equivalent safeguard hands, and respirators with organic vapor cartridges shield airways during high exposure Hygiene Measures: Make hand-washing frequent, especially after handling. Never eat, drink, or smoke in work areas
Appearance: Clear, colorless, mobile liquid Odor: Mildly sweet, strong, characteristic of ketones Boiling Point: Near 117°C (243°F) Melting Point: About -84°C (-119°F) Flash Point: Roughly 14°C (57°F), making it easy to ignite under standard conditions Specific Gravity: Around 0.8 (water at 1.0) Solubility: Slightly soluble in water, but mixes well with most organic solvents Vapor Pressure: Relatively high, contributing to fast evaporation
Chemical Stability: Stable when stored and handled in ordinary conditions, but decomposes if heated strongly or exposed to fire Reactivity: Reacts with strong oxidizers, acids, or bases and may produce hazardous products Decomposition Products: Flames can release carbon monoxide, carbon dioxide, and small amounts of hazardous organic chemicals Special Conditions: Avoid heat, sparks, electrical discharges, and incompatible materials
Routes of Exposure: Inhalation, ingestion, skin or eye contact Short-Term Effects: Headaches, nausea, and fatigue, even at low concentrations; high doses cause unconsciousness or central nervous system depression Long-Term Effects: Regular inhalation can slow liver and kidney function and bring skin allergies or dermatitis Cancer Risk: Some animal tests indicate possible carcinogenicity, but human evidence remains unconvincing
Environmental Fate: Evaporates quickly from surface water or soil, but breakdown in air is slow Aquatic Toxicity: Harmful to aquatic organisms at low concentrations, causing stress for fish and invertebrates Persistence: Rapid loss from open environments limits its buildup, but spills or large releases overwhelm natural balance Mobility: Moves swiftly through soil and groundwater in liquid form if spilled, so leaks near water sources bring lasting threats Bioaccumulation: Unlikely to pile up in animal tissue, but repeated exposure matters
Preferred Disposal Method: Incineration in a licensed chemical waste facility Restrictions: Never pour down drains, natural water bodies, or onto soil Special Handling: Collect waste in sealed, clearly labeled containers and hand off to professionals familiar with flammable, toxic materials Legal Requirements: Check and respect local or national hazardous waste regulations throughout the disposal process
UN Number: 1245 Shipping Name: Methyl Isobutyl Ketone Hazard Class: 3 (Flammable liquids) Packing Group: II (medium danger) Transport Advice: Ship securely in covered vehicles, keep containers upright and tightly closed, use warning labels required for flammable liquids, and provide special handling in case of accident or leakage en route
International Requirements: Covered by the Globally Harmonized System for Classification and Labeling of Chemicals (GHS) and numerous national worker safety laws Hazard Symbols: Flammable, Harmful, Irritant Restrictions: Strict workplace limits on concentrations, hazard communication on containers, and requirements for training workers on health risks and safe practices Reporting Obligations: Large users must keep documentation for compliance inspections and legal liability
