Isopropyl alcohol

Isopropyl alcohol is readily available. Like acetone, it dissolves a wide range of non-polar compounds. It also evaporates quickly and is relatively non-toxic, compared to alternative solvents. Thus it is used widely as a solvent and as a cleaning fluid, especially for dissolving li pophilic contaminants such as oil.

Examples include cleaning electronic devices such as contact pins (like those on ROM cartridges), magnetic tape and disk heads (such as those in audio and video tape recorders and floppy disk drives), the lenses of lasers in optical disc drives (e.g. CD, DVD) and removing thermal paste from IC packages (such as CPUs.) It is used to clean LCD and glass computer monitor screens (at some risk to the anti-reflection coating on some screens [citation needed]), and used to give second-hand or worn non-vinyl phonograph records newer-looking sheens.

Isopropyl alcohol should not be used to clean vinyl records as it may leach plasticizer from the vinyl making it more rigid [citation needed]). Isopropyl alcohol removes smudges, dirt, and fingerprints from cell phones and PDAs. It is effective at removing residual glue from some sticky labels although some other adhesives used on tapes and paper labels are resistant to it. It can also be used to remove stains from most fabrics, wood, cotton, etc.

Isopropyl alcohol is also used to remove brake fluid traces from hydraulic braking systems, so that the brake fluid (usually DOT 3, DOT 4 or mineral oil) does not contaminate the brake pads, which would result in poor braking. In addition it can also be used to clean paintballs or other oil based products so that they may be reused, commonly known as “repainting”. As a biological specimen preservative, isopropyl alcohol provides a comparatively non-toxic alternative to formaldehyde and other synthetic preservatives. Isopropyl alcohol solutions of 90-99% are optimal for preserving specimens, although concentrations as low as 70% can be used in emergencies.

Disinfecting pads typically contain a 60–70% solution of isopropyl alcohol in water. Isopropyl alcohol is also commonly used as a cleaner and solvent in industry.

Isopropyl alcohol is a major ingredient in “gas dryer” fuel additives. In significant quantities, water is a problem in fuel tanks, as it separates from the gasoline, and can freeze in the supply lines at cold temperatures. It does not remove water from gasoline; rather, the alcohol solubilizes water in gasoline. Once soluble, water does not pose the same risk as insoluble water as it will no longer accumulate in the supply lines and freeze. Isopropyl alcohol is often sold in aerosol cans as a windscreen de-icier.

Isopropyl alcohol is used in keyboard, LCD and laptop cleaning, is sold commercially as a whiteboard cleaner, and is a strong but safer alternative to common household cleaning products.

Isopropyl alcohol is often used in DNA extraction. It is added to a DNA solution in order to precipitate the DNA into a ‘pellet’ after centrifuging the DNA. This is possible because DNA is insoluble in isopropyl alcohol.

Isopropyl alcohol is used as a water-drying aid for the prevention of otitis externa, better known as swimmer’s ear

Explosive Limits: LEL: 2.5% UEL: 12.1%
Extinguishing Media
Water, fog, dry chemical, CO2, Alcohol foam
Fire Fighting Instructions
Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes. Water may be ineffective for fire fighting. Use water spray to keep fire-exposed containers cool and to protect personnel. If a leak or spill has not ignited, use water spray to disperse the vapors. Either allow fire to burn under controlled conditions or extinguish with alcohol-type foam and dry chemical. Try to cover liquid spills with foam.
Flammable Properties and Hazards
Flammable liquid. Vapors are heavier than air and may travel considerable distance to a source of ignition and flash back. Run-off from fire control may cause pollution.
Hazardous Combustion Products
No data available.

**LARGE SPILLS** Evacuate hazard area of unprotected personnel. Wear appropriate respirator and protective clothing. Shut off source of leak only if safe to do so. Dike and contain. If vapor cloud forms, water fog may be used to suppress; contain run-off. Remove with vacuum trucks or pump to storage/salvage vessels. Soak up residue with an absorbent such as clay, sand or other suitable material; place in non-leaking containers for proper disposal. Flush area with water to remove trace residue; dispose of flush solution as above.
**SMALL SPILLS** Take up with an absorbent material and place in non-leaking containers; seal tightly for proper disposal.
