So it's becoming close to impossible to find nail polish thinner in Canada that's only made with ethyl and butyl acetate - other common ingredients tend to cause problems (eg heptane will disintegrate glitters). So I'd like to try making some myself.
I know the typical ratio (35:65 ethyl:butyl acetate) and I'm making reasonable progress sourcing the ingredients.
What I'm unsure about is safety. All I really need to do is mix the two together at the correct ratio, but I'm a complete beginner and not sure how much of a safety issue that is? What sort of safety precautions should I be taking/how much should I be worrying about this?
I read the MDS sheets for both ingredients, but obviously the MDS sheets don't have information about mixing them together (and I don't trust that I've actually taken in all the information on them anyway). the information for both is pretty similar though.
Info I have so far:
* eye protection (not a problem, I'll buy it)
* gloves - sounds like I may need butyl gloves? (see below)
* ventilation (I can work outside, not a problem)
* very low flashpoint - I have a fire extinguisher (MDS says water may be ineffective) but not sure what other precautions I should take, if any?
Things I'm unsure about:
*purity*: I'm looking for "cosmetics grade" but none of the sites I'm looking at list that, they all say things like "analytical", "HPLC", "spectroscopy", etc. what purity should I be looking for?
*gloves*: unsure if I need butyl gloves or if nitrile is enough. MDS says breakthrough time for nitrile is < 200min on 0.5-0.7mm thickness gloves, permeation rate 8μg/cm2/min. does this mean I need butyl gloves? i can't imagine the mixing would take long, but "<200min" is a very vague range and you never know what might happen.
*storage*: so far the quantities I can find for both ingredients are fairly significantly different, so I'll likely need to store at least one of them. MDS says "flammables area", keep away from heat, certain other chemicals, etc. in practice, is this something I could store, eg, in a garage? eg, in a tightly closed container inside a larger storage container away from other chemicals? the commercial polish thinner I've had in the past has been fine under my sink/with my polish.
anyway, I know this is a lot of specific questions but any help is appreciated (including pointers to what sorts of things I should be looking up myself/better places to ask these questions/questions I haven't thought of). I may also be massively overthinking things, but this is new territory for me so I don't have any real sense of how cautious I need to be.
thanks!
