While considering tricks that a non-fighter warforge could use when up against a more powerful adversary, I came across an article which mentioned that one could carry a small bag of sand with them for throwing into the eyes of their enemies in order to escape. Although this might be sometimes more effective then just running away, it likely isn't that effective from what I believe the rules said would happen if such a technique was used. My question is if my warforge character is in a tight spot (I'm unsure if I'm going to use a scout, mage, or cleric yet) and IF I don't have to worry about effecting any PCs or other friendlies, what would the the effects of throwing a handful of lye into an enemy's eyes verses something like sand or blinding powder;  or perhaps a mixture of blinding powder and lye.     >:)

I'm not sure if there are official rules about such a thing. Lye is a powder much like chalk or flour so is not easy to throw. It's also corrosive so will need a special container and gloves. You might be better off using flasks of oil or alchemist fire. If you have the right proficiency, nets are effective for tying up opposition (hard to hit with though).

I wasn't aware that lye had the consistency of powder but I'm pretty sure such an issue could be resolved by mixing it with other substances which are not powder-like so that the lye is merely covering the surface yet still present enough to burn an attacker's eyes if any sand/blinding powder enters it and/or breathes it. Also as I mentioned that character I considering doing this is a Warforged (ie. metal/wood construct who doesn't breath, immune to many things that hurt organic beings) who would likely NOT require gloves special protection from the handling/side effects of being using lye as such a weapon.  Also I'm aware of flasks of oil and alchemist fire and considering using them as well, but not for close combat use (other than for a suicide type scenario) since the area of effect would surely hurt my PC just as much as any enemy.  As I mentioned before, this is just a last-ditch-effort type of weapon, where no other PC are near enough to help me (or be hurt by it) and I have something like an huge ogre barreling done on my level 1 or 2 non-fighter type PC so that they may have an extra round or two to run away or whatever.      

Ok....Since coming up with how with the effects of how blinding powder mixed with lye might behave might be difficult, here is a description of regular blinding powder:

========================================================================================================================

 I'm unsure how someone rubbing their eyes for one round or so can successfully remove powder glass and/or metal shavings from their eyes so that it no longer bothers them but other than that I more or less agree however IMHO I would also say that whatever they do after that they would do at either a disadvantage and/or with a penalty until they spend a couple rounds flushing their eyes out with water.   

I'm guessing if someone used a mixture of sand/powder glass and/or metal shavings/lye (sand being the easiest to coat/throw and the other two being the extra nastiness added to the mix) that it would at LEAST take more than one round to remove the substances from their eyes and perhaps their might even be a penalty/addition danger to anyone who breathes it.  I'm pretty sure the effects might be even equivalent to  an D&D spell that causes coughing and choking.  Also lye has an addition NASTY effect of being triggered when exposed to water (with it is so detrimental to organic/water based beings)  and when it gets into either one's eyes and/or lungs it is very, very painful and can cause permanent blindness and possible asphyxiation.  

At least this is my thoughts on the matter..... 

That looks like you have to ask your GM about it.
