Narrative:

Preflighting aircraft after it taxied in and safety zone was cleared for my entry. As I ducked under the nose a liquid started streaming off the side of the nose and fell onto the side of my head and then ran into my left eye. It caused a slight burning for two minutes. It had an orange smell. I ran up into the jetway and the inbound crew said it was rain repellent and they had an uncommanded discharge of it on approach; which obscured the fos windscreen so he asked the captain to land.I got my toiletry bag; found a custodian who directed me to a baby changing bathroom; and I removed my left contact lens and rinsed my eye under tap water for five minutes. I discarded my brand new contact lens. I called the operations center phone number and without knowing reached the dispatch desk and got a general dispatcher. They connected me with maintenance control who told me to rinse my eye; as a general precaution. They stated they could not find the material safety data sheet (msds). I asked that they text me when they found the information we needed. I didn't receive any texts.I dried my face and returned to my aircraft. I decided to get an official second opinion; so I called chief pilot on call. He said he would feel better if I got checked out by EMS. Firemen came with paramedics outside. Firemen said I should rinse. I told them I did. They said it looked good. I could leave or go in ambulance to hospital. What were they going to do besides rinse my eye? I returned to the aircraft. We had no luck searching for msds online but fireman pointed out msds third party phone number under glass on table top. I called and they emailed me msds; which I need to yet analyze. I plan on seeing a doctor after I return home.first of all; inbound crew should alert station in range to potentially hazardous chemical. They did not. Second of all; absolute best source of guidance; msds; was not available to me via maintenance control. Third; the data shows rain repellent as rainboe; the canister says lebozec. I would like an msds mailed to my home address for that product. Maybe it's the same chemical; maybe not. How are we to know? Find out; and then let me know. I'm kind of angrier about this situation the more I write about it.
