Is Peladow a safe alternative to Dowflake?

[reddfish]

So I've finally tracked down some Dow calcium chloride products in my local area, (which rarely freezes, so this was a challenge). I had a local Ace hardware special order some Peladow, which is made by Dow, but has a higher concentration of calcium chloride. It also appears to have different salts than Dowflake. On the bag it lists its contents as 90-96% calcium chloride, 2-6% water, sodium chloride -%, strontium chloride -%, and potassium chloride-%. On the peladow datasheet (http://www.dow.com/calcium/product/pelad_pp.htm), found on the product information page from the Dow website, there is a list of "Typical Chemical properties" that says nothing about the strontium, potassium, or sodium chloride concentrations, but does list the same 'items' as the datasheet from the product page for Dowflake (http://www.dow.com/calcium/product/dowfl_pp.htm).

So, my question for Mr. Holmes-Farley, or any other competent source, is whether or not the Peladow could be a safe alternative to Dowflake (in Mr. Holmes-Farley's DIY 2 pt. Kalkwasser recipe) if one adjusts recipe quantities for the difference in calcium chloride composition.

Thanks in advance for any response.

After taking a closer look at the datasheet pages of both Peladow and Dowflake, I've found one main difference, though I have yet to track down the significance. Dowflake is made from "Type S; Grade 1, Class A" calcium chloride, and Peladow is made from "Type S, Grade 2, Class B" calcium chloride. These are under the ASTM classification system. Will get to a search on that asap, but would still appreciate any knowledge on the topic that anyone (like Mr. Holmes-Farley might have to offer. Cheers

Apartly Peladow is a more dehydrated version which is about about 10-20% more potent.

Thats what I concluded as well. I bought a bag, but haven't tried using any of it yet.
