Q: I see Sodium Carbonate listed on the label. Is Concrobium Mold Control just Sodium Carbonate (washing soda) and water?
A: No. Sodium Carbonate is the listed “active ingredient” on the Concrobium Mold Control label, but in fact there are two other ingredients in the solution which, when combined with the sodium carbonate and the water, result in this patented tri-salt polymer that eliminates and prevents mold. (Sodium Carbonate and water alone are not effective against mold.) The solution contains no bleach, ammonia or VOCs. Our Material Safety Data Sheet is posted on our website.
The MSDS lists two particular ingredients:
Chemical Name CAS # % by Wt
Trisodium phosphate 7601-54-9 1-5
Sodium Carbonate 497-19-8 < 1
I'm guessing the third might be water.
Question: What might the term "tri-salt polymer" refer to in general, and if possible to answer, what might it be in this particular case?
I did find a patent in a google search but I'm not sure of it's relevance and I don't understand it.
