Wow, my association with oleoresin of capsaicin has been very painful. Now I am reminded (again) of the wonderful feeling of it in my eyes, mouth, nose and all over my face. This is the active ingredient in pepper spray! I have been hosed down once, and the second time it was applied to my eye with a q-tip; this was a requirement to be allowed to carry it in a Law Enforcement (LE) capacity (old life, never again. Not only did I lose any desire to continue in LE, my AS would never let me do it anyway). Never did figure it out why, they never shot me with a pistol to allow me to carry it! On the notes about allergies, that is why my agency quit doing full face sprays. Apparently a couple of people had severe reactions after getting sprayed in the face. Although, it is still carried and used. I personally think that the risk of severe reaction is enough reason to stop using it on the public.
Word of advice: If you EVER touch your eyes or face when you have capsaicin cream on your hands it is the same as getting sprayed. Baby shampoo works wonders for getting it out of your eyes and face though.
