Frozen nutes still good?

I bought a bottle of Power Cloner to help with my next batch of clones. The bottle fell out of the bag while in my truck and was left outside overnight. It was below freezing and when I found it the next morning it was frozen solid. If I let it thaw out will it be just as good or will the freezing / thaw cause adverse effects of some kind. Would rather not have to buy this stuff again as its crazy expensive.
