So I'm in the habit of checking MSDS sheets now, thanks to the TFP. However in one case, it has me more confused. Natural Chemistry Metal Free shows 1% citric acid. What is the other 99%? I'm trying to determine if this is a HEDP sequestrant. They claim it is phosphate free, so that rules out phosphonic acid.

I have a bottle of this left over and would like to use it up this week.
