What does the back say? I can't imagine that it is food safe. Not much of a good reason to make potable caulk though. What are you looking to use it for.

As long as it's 100% silicone with no mold inhibitors it should be OK. I'd go with clear one in the middle.
 
I wouldn't want to trust it. It's just not worth putting your tank at risk to save a few dollars. You savings in only a few dollars over typical aquarium grade silicone, and put your tank at risk.
 
I am stopping at HD on the way home and getting a tube of good ole GE Silicone I which I have used for years. Not worth the risk.
