I am assuming aerosol products are not used inside the living environment of a spacecraft while it is microgravity. Is that correct, or are there examples of such products being used while an individual or crew are in microgravity?

    $\begingroup$ The same sources I used in this answer about WD-40 returned nothing about aerosols. I don't recall having read about them anywhere else. I would expect them difficult to control and possibly fouling the cabin air. $\endgroup$

    $\begingroup$ I am unaware of any aerosol cans ever being carried on Shuttle. No idea how to confirm this though. $\endgroup$ Sep 18, 2019 at 13:21

    $\begingroup$ Given that such products would have undoubtedly been included in the following study, I have to conclude that they are not allowed on the ISS: ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20150000882.pdf $\endgroup$
