Nope.
For greenstuff you don't even need IPA at all.
For working with it I recommend using plain water.
Just mix up the greenstuff using your fingers until its all green in your hand. Equal parts blue and yellow is the default, but you can add more of one than the other for either a stronger final cure or a more malleable one, though I forget which does which.
Then wet your tools that you are working with with standard water. This helps stop the greenstuff sticking to them but still lets you manipulate it. Rewet your tools every so often as you work.
Once you're done simply leave the greenstuff in the air to cure, it takes about 24 hours to cure fully, but can be fairly firm after an hour or two. You can also bake it (heat) to speed this process up.
For tools themselves I find that standard clay tools are great. You can get a whole set of metal clay tools for not very much on ebay and the like. In addition I'd strongly suggest getting some clay/colour shapers (same tool just different names). They are fantastic as they are a soft silicon tipped tool that lets you smooth over greenstuff. This can create very soft and smooth edges and surfaces and they are invaluable tools. They typically come in sets of 5 different head shapes and in 3 colours - black hardest, then grey then white as the softest. Though even the black tip is very soft. In theory you can smooth over from black to white to get a really smooth surface, though I have to admit a lot of the time my most used is a cone tipped black colourshaper/clayshaper.
Again I'm only using water on the tool to stop the greenstuff sticking too it as I work .
If you want a bit more work time than water you can use regular oil (eg olive oil, vegetable oil); though if you use oil, once the model is cured you want to give it a light wash in warm (not hot) and lightly soapy water to get the oil residue off otherwise it will mess with any primer and paint adhesion.
I think if you look up standard "greenstuff modelling" and hobby type stuff on youtube and the like you should find some good guides on it.
