Chemical name: 2-Methyl-2,4-Pentanediol
Synonyms: Hexylene glycol, 2,4-Pentanediol, 2-methyl-, 2-Methylpentane-2,4-diol
Appearance: Clear, viscous liquid without strong color
Odor: Mild, not overpowering
Uses: Many industries use hexylene glycol in paints, coatings, solvents, and industrial cleaners because it mixes well with water and organic materials
Main hazards: Exposure can cause irritation to eyes and skin, and inhalation of vapors may upset breathing or cause dizziness
Acute symptoms: Direct contact might cause redness, burning, and in severe cases blisters; breathing high concentrations could irritate the respiratory tract
Chronic effects: Prolonged exposure has not been linked to cancer, but frequent skin contact could dry out skin leading to dermatitis
Safety statements: Keep out of reach of children and avoid direct skin or eye contact during handling
Main ingredient: 2-Methyl-2,4-Pentanediol, typically at a level above 99% purity
Impurities: May contain trace amounts of water or byproducts from synthesis, usually in fractions far below one percent
Inhalation: Remove affected person to fresh air as soon as possible, seek medical advice for continued breathing trouble
Skin contact: Wash area with plenty of soap and water for at least 15 minutes, take off contaminated clothing
Eye contact: Rinse with water for at least 15 minutes, lifting lids frequently, and seek further medical evaluation if pain continues
Ingestion: Do not attempt to induce vomiting, rinse mouth thoroughly, get prompt medical attention
Suitable extinguishing media: Use water spray, dry chemical, carbon dioxide, or foam
Specific hazards: Upon burning, the product can generate carbon oxides and other toxic fumes
Protective equipment: Firefighters should wear self-contained breathing apparatus and chemical-resistant clothing
Advice: Stay upwind in open areas and avoid breathing vapors
Personal precautions: Use gloves and splash-proof goggles to keep contact away from eyes and skin
Environmental precautions: Prevent entry into drains or water systems to avoid environmental contamination
Clean-up: Absorb liquid using sand, earth, or inert material and place in proper waste disposal containers, ventilate area thoroughly after cleanup
Handling: Work in well-ventilated places, wear protective gear, avoid inhaling vapors, do not eat, drink, or smoke during handling
Storage: Keep containers tightly closed, away from heat, incompatible materials including strong oxidizers, and out of direct sunlight
Special instructions: Prevent spills and keep the work area dry and orderly
Exposure limits: There is no specific workplace limit, yet minimizing exposure always lowers risk
Ventilation: Use good local or general exhaust to keep air concentrations below levels that cause irritation
Personal protective equipment: Wear nitrile or neoprene gloves, safety goggles, and protective clothing; respiratory protection may be needed for high vapor concentrations
Hygiene measures: Always wash hands after use and before eating or drinking, store work clothes separately from regular clothing
Physical state: Liquid
Color: Clear, colorless
Odor: Faint, slightly sweet
Boiling point: Above 200°C
Melting point: Below room temperature
Solubility: Completely soluble in water and most organic solvents
Flash point: About 107°C (closed cup); remember that high vapor concentrations can still ignite around ignition sources
Chemical stability: Stable under standard conditions if not exposed to high heat or sunlight
Reactivity: Can react strongly with strong oxidizers leading to fire or explosions
Decomposition: Burning or overheating releases hazardous fumes, including carbon monoxide and carbon dioxide
Routes of exposure: Can get into the body through inhalation, ingestion, or skin and eye contact
Symptoms of exposure: Inhalation might cause headache or nausea; skin and eye contact can lead to redness, discomfort, or burns; swallowing can irritate stomach and digestive tract
Chronic effects: Long exposure raises skin drying risk, especially among workers not using protective gloves
Carcinogenicity: Evidence does not link 2-Methyl-2,4-Pentanediol to cancer in humans
Other long-term risks: Repeated inhalation of high levels could stress the kidneys and liver
Aquatic toxicity: Large spills may harm fish and aquatic life, since the substance can lower oxygen in water
Mobility: High water solubility means leaks can spread quickly in water systems
Degradability: Breaks down under most environmental conditions, though large releases can overwhelm local areas
Bioaccumulation: Unlikely to build up within living organisms
Waste management: Collect waste in clearly labeled, secure containers and send to licensed chemical disposal centers
Drain disposal: Never pour into sinks, drains, or sewers because of risk to water supplies and aquatic life
Container disposal: Empty containers should be triple rinsed, punctured, and sent to facilities designed for chemical recycling or disposal
Land, sea, and air transport requirements: While 2-Methyl-2,4-Pentanediol does not fall under strict hazardous goods classes, proper labeling and secure packaging limit leaks and spills in transit
Labeling advice: Use the correct chemical name on containers and include hazard labeling to help carriers and emergency personnel respond quickly if a spill occurs
Workplace safety laws: Most guidance centers around keeping exposure to a minimum using established industrial hygiene controls
Environmental rules: Regulations prevent dumping or uncontrolled release
Worker protection: Employers must ensure personal protective equipment is available for employees directly handling this chemical
