FreezePruf has Arrived! (back label scan)

Post by Doug-Tews » Thu Sep 17, 2009 7:48 pm

My gallon of FreezePruf concentrate arrived today. :D I've scanned the back label for those interested. I know a lot of people will be interested in the ingredients. However, I believe that information is likely deliberately mislabeled.

In the US, one must list "active" vs. "inactive" ingredients. By definition, active ingredients are the ones delivering the desired effect. Inactive ingredients are usually carriers for the active ingredients, or simply fillers. Percentages of active ingredients must be listed, however, inactive ingredients may be lumped together without specifying their individual percentages.

For example, Potassium salt is listed as an inactive ingredient. However, in a previous discussion (in this, or another forum) someone mentioned potassium can help strengthen cell walls and might be one of the ingredients used in this formulation. It turns out this is the case, and therefore should be listed as an active ingredient.

I suspect, that in reality, the most important ingredients are listed as "inactive" so the exact percentages are not revealed. One article stated the exact ratio of all the ingredients in this formulation was critical for maximum effect. It should also be noted that "Bicyclic Oxozolidines" are apparently a family of related chemicals, so again we don't know precisely what is being used here.

Of the so-called "active ingredients", I suspect the Polyethylene glycol 8000 is likely a carrier for the more important ingredients. And Glycerin is perhaps being used as a wetting agent. Glycerin in particular would normally be listed as an inactive ingredient, so I suspect some subterfuge in the labeling is occurring until the patent is granted.

One nice surprise: When purchased, the online info said this gallon of concentrate would make two gallons of solution. However, it's actually 4 to 1 dilution, so I'm getting twice as much as I had hoped! icon_cheers
