Pepper-spray is not just capsaicin. The capsaicin is emulsified in propylene glycol and then mixed into water and pressurized. Other emulsifiers in the past have been ethanol. The capsaicin for law enforcement use is ~2%, personal pepper-spray is about the same, though it varies more. Propylene glycol is mostly non-irritating to the eyes, even in pretty high dosages times, barring allergies to it. Likely it was the pressurization issue that just blasted the person's eyes. Meaning that the pepper-spray had to be right up in there. I would not want to take a hist from a garden hose at full blast to my eyes, let alone something like that. https://en.wikipedia.org/wiki/Pepper_spray https://en.wikipedia.org/wiki/Pepper_spray https://en.wikipedia.org/wiki/Propylene_glycol https://en.wikipedia.org/wiki/Propylene_glycol
