Strange Green Goo on sink water valves

[beyondo]

There's some sort of green goo dripping very slowly from where the water lines exit the water valves for the sink and dishwasherer (in the kitchen) and for the sink (in the bathroom). It's not corrosion on the pipe (not now at least, not sure where it came from). It's not water, it feels gooey like jelly. It's been there for several months (at least). Dime size spot on the wood below right now.

What is it?

Many times, installers use liquid soap as a lubricant when hooking up the hoses, but not knowing if this is a new or old installation, I would only be guessing.

Are these joints soldered? Could be excess flux.
