| GHS signal word | Danger |
|---|---|
| Hazard classification | EU harmonised classification - CLP Annex VI, Index 606-001-00-8: Flam. Liq. 2 - H225; Eye Irrit. 2 - H319; STOT SE 3 - H336; plus supplemental EUH066 (repeated exposure may cause skin dryness or cracking) |
| Substance | Acetone |
|---|---|
| C.A.S. number | 67-64-1 |
| Molecular weight | 58.1 (ILO ICSC 0087 and NIOSH Pocket Guide) |
| Composition | 99.5% min |
| Eye contact | Rinse immediately and thoroughly with plenty of lukewarm running water for at least 15 minutes, holding the eyelids apart and rinsing under the eyelids; remove contact lenses if easily possible and continue rinsing. Refer for medical attention if pain, redness or visual disturbance persists. |
|---|---|
| Skin contact | Remove contaminated clothing and shoes immediately. Wash the affected skin with plenty of soap and water. Refer for medical attention if irritation develops. Launder clothing before reuse; repeated or prolonged contact defats the skin and causes dryness and cracking (EUH066), so gloves and barrier cream matter for routine handlers. |
| Inhalation | Move the casualty to fresh air at once and keep them at rest in a position comfortable for breathing; loosen tight clothing. Give oxygen if breathing is difficult and artificial respiration if breathing has stopped. Because the vapour causes drowsiness and dizziness (H336), do not allow the casualty to walk about unaccompanied or return to the area until it is ventilated. Refer for medical attention. |
| Ingestion | Do NOT induce vomiting - aspiration of acetone into the lungs must be avoided. Rinse the mouth with water. Give nothing by mouth to an unconscious or drowsy casualty. Call a physician or poison centre immediately and obtain medical attention. |
| Flash point | -18 C closed cup (ILO ICSC 0087). Producer sheets give -17 C and the NIOSH Pocket Guide gives 0 F (-17.8 C). Always quote the closed-cup value and say so. |
|---|---|
| Suitable extinguishing media | This material has a flash point and burns. Use alcohol-resistant foam, dry chemical powder or carbon dioxide; water spray or fog to cool surrounding surfaces and containers. Confirm the medium against the producer’s safety data sheet for the grade supplied. |
| Unsuitable extinguishing media | Do not use a high-pressure water jet: it will spread the material and the fire. A vapour flash-back to the source and re-ignition of cooled but still-hot material are both foreseeable; do not approach a container that may be pressurised or a pool fire without cover. |
| Special hazards arising from the substance | Hazardous gases and decomposition products may be formed in a fire, from this substance or from its packaging and the materials stored with it. Packaging and pallets are themselves a substantial fire load. |
| Advice for fire-fighters | Fire-fighters must wear self-contained breathing apparatus and full protective clothing. Keep unnecessary personnel away and upwind. Prevent firefighting run-off from entering drains, surface water or groundwater. |
Keep unnecessary personnel away and upwind, and ventilate. Wear the protective equipment in section 8 before approaching. Stop the leak if it is safe to do so, then bund or dike the spill and prevent entry to drains, surface water and groundwater. Absorb with an inert absorbent and collect into labelled, closable containers for disposal under section 13. Do not return spilled material to the original container.
• Highly flammable (Class 3, UN 1090), with a flash point well below room temperature. The vapour is heavier than air and can travel to an ignition source — store in a ventilated flameproof area, earth and bond drums and tankers during transfer, and allow no naked flames or sparks.
• Acetone attacks many plastics, rubbers and paints. Check gaskets, hoses and seals: PTFE, EPDM or butyl for seals and hoses; stainless or carbon steel for tanks and lines. Viton (FKM), nitrile, neoprene and PVC are attacked.
• Keep it away from strong oxidisers. The vapour causes drowsiness and dizziness and the liquid irritates eyes; use with good ventilation and eye protection.
Storage: Store in the original, tightly closed, correctly labelled container in a cool, dry, well-ventilated, fire-resistant store, away from all sources of ignition, heat, hot surfaces, sparks, open flames and direct sunlight, and separated from oxidisers, acids and bases. Earth and bond drums, tanks and transfer lines and use non-sparking tools and explosion-protected electrical equipment - the liquid is a poor conductor and accumulates static. Keep the store bunded and without drain or sewer access. Do not store with foodstuffs. Keep containers closed when not in use; do not use compressed air to transfer.
Engineering controls. Enclose every transfer, tipping, bag-slitting and sampling point and fit local exhaust extraction at each, and keep airborne concentrations below the limit in force at the place of use. Provide an eyewash within reach of the working position, and a safety shower wherever the material is classified corrosive or irritant or is handled in quantity. Do not eat, drink or smoke in the handling area; wash before breaks. Where no limit is stated above, occupational exposure limits vary by jurisdiction: check the limit in force at the place of use and the producer’s sheet for the grade supplied, and record which value your assessment adopted. Select eye, skin and respiratory protection on the strength of a measured or modelled exposure assessment, not on this sheet alone.
| Appearance | Clear, colourless, mobile, volatile liquid with a characteristic sweet mint-like solvent odour |
|---|---|
| Physical state | Liquid |
| Melting / freezing point | -95 |
| Boiling point | 56 (producer sheets give 55-57 C; NIOSH gives 133 F = 56.1 C) |
| Relative density | 0.79 g/cm3 at 20 C (relative density 0.79, water = 1); vapour density about 2.0 relative to air, so vapour sinks and travels along the ground |
| Solubility in water | Completely miscible with water in all proportions; also miscible with ethanol, diethyl ether and most organic solvents |
| pH | Not applicable - acetone is a neutral, non-ionising organic liquid and no meaningful aqueous pH is defined. Producer SDSs state 'not applicable'. Commercial 99.5% grades specify acidity as % free acid (as acetic acid) rather than pH. |
| Flash point | -18 C closed cup (ILO ICSC 0087). Producer sheets give -17 C and the NIOSH Pocket Guide gives 0 F (-17.8 C). Always quote the closed-cup value and say so. |
| Auto-ignition / ignition temperature | Not available |
| Explosive / dust-explosion properties | Not available |
| Vapour pressure | Not available |
| Vapour density | Not available |
| Partition coefficient (log Pow) | Not available |
| Particle characteristics | Not available |
| Molecular weight | 58.1 (ILO ICSC 0087 and NIOSH Pocket Guide) |
| Incompatible materials | Strong oxidising agents - nitric acid, sulfuric/nitric mixtures, hydrogen peroxide, peroxides, chromic acid, chlorates, perchlorates (contact can generate explosive peroxides and cause violent reaction). Strong acids and strong bases. Alkali metals and alkaline-earth metals. Amines and ammonia. Halogens, and bromoform/chloroform in the presence of base (forms explosive products). Acetone also dissolves or crazes many plastics, coatings, resins and rubbers - check gasket, hose and liner compatibility before use. |
|---|---|
| Conditions to avoid | Store in the original, tightly closed, correctly labelled container in a cool, dry, well-ventilated, fire-resistant store, away from all sources of ignition, heat, hot surfaces, sparks, open flames and direct sunlight, and separated from oxidisers, acids and bases. Earth and bond drums, tanks and transfer lines and use non-sparking tools and explosion-protected electrical equipment - the liquid is a poor conductor and accumulates static. Keep the store bunded and without drain or sewer access. Do not store with foodstuffs. Keep containers closed when not in use; do not use compressed air to transfer. |
The health hazards classified for this substance are listed in section 2, and the corresponding first-aid measures in section 4. Numerical toxicological endpoints are not reproduced here: refer to the producer's safety data sheet for the grade supplied, and to the ECHA and PubChem entries for the substance.
Where section 2 or section 14 classifies this substance as hazardous to the aquatic environment, prevent any release to drains, surface water or groundwater and treat aqueous effluent before discharge. Otherwise, refer to the producer's sheet.
Dispose of the substance and its container through an authorised facility under the Hazardous and Other Wastes (Management and Transboundary Movement) Rules, 2016 where the waste is scheduled under those Rules, and otherwise as non-hazardous industrial waste, in each case under the conditions of the State Pollution Control Board consent in force at the site. Whether a particular waste stream is scheduled depends on the substance and on what it has been mixed with, so classify the waste before consigning it. Do not reuse empty containers for any other purpose.
| UN number | UN 1090 |

| Proper shipping name | ACETONE |
Supply in India is subject to the Manufacture, Storage and Import of Hazardous Chemical Rules, 1989 where the substance is scheduled, and to any product-specific licensing named on the product page. Classification and labelling follow the GHS as adopted in the jurisdiction of use.
Note: The practical hazard exceeds what the flash point alone suggests: acetone's vapour is about twice as dense as air, so it collects in pits, sumps and along floors and can reach an ignition source many metres from the point of release. Flash point figures differ between sheets only because of open-cup versus closed-cup method, not because of product quality; the closed-cup value is about -18 C. Auto-ignition temperature 465 C; explosive limits about 2.2-13 vol% in air (ILO ICSC 0087), with one producer sheet giving an upper limit of 14.3 vol% - the lower figure is the conservative one to design to. Vapour pressure is high (24 kPa / about 180 mmHg at 20 C), so drums breathe and partly emptied containers develop flammable headspaces. A 99.5% min commercial grade behaves as the pure solvent for all safety purposes. Acetone is not classified as hazardous to the aquatic environment and carries no environmental transport marking, but it is fully water-miscible and must still be kept out of drains.
