Safety
Isopropyl alcohol vapor is heavier than air and is highly flammable (http://en.wikipedia.org/wiki/Flammable) with a very wide combustible range. It should be kept away from heat and open flame. When mixed with air or other oxidizers it can explode through deflagration (http://en.wikipedia.org/wiki/Deflagration).[4] (http://en.wikipedia.org/wiki/Isopropyl_alcohol#_note-3)
Isopropyl alcohol is oxidized by the liver into acetone (http://en.wikipedia.org/wiki/Acetone). Symptoms (http://en.wikipedia.org/wiki/Symptom) of isopropyl alcohol poisoning include flushing (http://en.wikipedia.org/wiki/Flushing_%28physiology%29), headache (http://en.wikipedia.org/wiki/Headache), dizziness (http://en.wikipedia.org/wiki/Dizziness), CNS depression (http://en.wikipedia.org/wiki/CNS_depression), nausea (http://en.wikipedia.org/wiki/Nausea), vomiting (http://en.wikipedia.org/wiki/Vomiting), anesthesia (http://en.wikipedia.org/wiki/Anesthesia), and coma (http://en.wikipedia.org/wiki/Coma). Use in well-ventilated areas and use protective gloves while using. Poisoning can occur from ingestion, inhalation, or absorption.
Long term application to the skin can cause defatting (http://en.wikipedia.org/wiki/Defatting).

Medicine/Toxicology

Isopropyl alcohol is about twice as toxic as ethanol (http://en.wikipedia.org/wiki/Ethanol). Isopropyl alcohol does not cause an anion gap (http://en.wikipedia.org/wiki/Anion_gap) acidosis (http://en.wikipedia.org/wiki/Acidosis) (like ethanol (http://en.wikipedia.org/wiki/Ethanol) or methanol (http://en.wikipedia.org/wiki/Methanol)). It produces an elevated osmolal gap (http://en.wikipedia.org/wiki/Osmolal_gap), but generally no abnormal anion gap (though this may be seen as a result of hypotension (http://en.wikipedia.org/wiki/Hypotension) and lactic acidosis (http://en.wikipedia.org/wiki/Lactic_acidosis)). Overdoses may cause a fruity odor on the breath as a result of its metabolism to give acetone (http://en.wikipedia.org/wiki/Acetone) (which is not further metabolised)[5] (http://en.wikipedia.org/wiki/Isopropyl_alcohol#_note-4). While large quantities of isopropanol can be fatal if left untreated, it is not nearly as toxic as methanol or ethylene glycol.

This is important info to know - that not all alcohols are created equal.

Especially important since Isopropyl is a first choice for cleaning many airbrush body paints.

And of course it is smart to be carefull with open flames and smoking around any work environment. In a typical airbrush environment, we've not been able to make a blow torch out of any alcohol in an airbrush. And boy, did we try.

You also have to take into account that that MSDS is for PURE Isopropyl alcohol, which you will pretty much never find commercially. You won't find it at WalMart anyway.
Most Iso products are pretty heavily diluted. Not that you shouldn't be smart about where, when, and how you use it, or any chemical, but any MSDS basically assumes worst case senario, which makes sense since thats what they're for.

i use the stuff all the time, some use vodka or gin, Atelier sell it under thier brand name as an unlocking formula for thier interactive acrylic systems. Golden do a flow additive with some pretty nasty stuff in it that can cause permanent eye damage but so many folk fail to read the labels and take it for granted that becouse its an aditive for artist grade acrylic paint it is therefor safe

isopropyl must be used wisely but its safe enough compared to solvent based paint systems .propylene glycol is a completly non toxic alternative to isopropyl alcohol and doese much the same job

i feel people get worried when they hear chemicals being described under thier correct name acetic acid for example is plain viniger but sounds pretty nasty if you are unaware of its common name

i little homework and understanding goese a long way when useing additives and keeping things in perspective helps

im perfectly at home useing it as are many othere artists past and present
