DO NOT use this I made that mistake once. It will kill your yeast. Quat is one of the most effective sanitizers out there but it is not yeast friendly.
I work at a seafood smoker so I have access to quat too. I tried it with horrible results.
I was too dang lazy to go get sanitizer and brought home some from work.

Neither is StarSan. By definition a sanitizer kills or disables microorganisms. StarSan may be "yeast friendly" in that in the correct dilution, once you've dumped it out the small amount remaining won't interfere enough with the process to be of concern. But I'm sure if you mixed your yeast starter into a volume of StarSan the future of the little guys would look pretty bleak.
+1 to the above post. Yeast added to straight starsan will kill them. When starsans ph is raised by adding wort to your starsan foamed carboy then starsan turns into yeast food
