The problem with using IPA is that you can easily die if you drink it.

Random fact - IPA is not that toxic. If you drink it, your body will happily oxidize it to acetone. Acetone is not that toxic since your body produces it when burning fat. Estimated fatal dose of IPA is 500mL.

TIL. However, the CDC quotes a source saying it’s about half that:

> Human data: Ten volunteers exposed for 3 to 5 minutes to 200, 400, or 800 ppm reported mild to moderate irritation of the eyes, nose, and throat at the two higher concentrations [Nelson et al. 1943]. The probable lethal oral dose has been reported to be 190 grams [Gosselin et al. 1984].

https://www.cdc.gov/niosh/idlh/67630.html

IPA has a density of 0.786 g/cm3 (20 °C) (per Wikipedia), so that’s 190/0.786 = 242 ml (about 8 oz).

LD50 and estimation of fatal doses can be tricky. Opting for “overly conservative” is hardly inappropriate either. So I wouldn’t be surprised if both of these numbers were correct for different testing criteria.

Should’ve said “more easily die”. It’s definitely no methanol though.
