If it was a "wet" capacitor with a gel / liquid electrolyte, that was likely either ethylene glycol (aka "anti-freeze") or boric acid (think Borax laundry soap). If it was a solid capacitor, the equivalent of an electrolyte was another film of manganese dioxide (MnO2). Wet caps usually pop, but not smoke.

The two scientists initially determined, by ion chromatography and mass spectrometry, that there was hydrogen gas present in failed capacitors, leading to bulging of the capacitor's case or bursting of the vent. Thus it was proved that the oxidation takes place in accordance with the first step of aluminium oxide formation.
