What Am I? Number 5

Below I’ve listed the key chemicals found in a common household product.  I’ve drawn the chemical structures of principal components where simple and appropriate; given the E number or CAS number (however tempting Sigma-Aldrich catalogue numbers would be) if no simple chemical structure exists for an additive; and given the chemical formulae or name if neither of the above make sense.  See if you can guess what this is!  If no one gets it within 24 hours, I will post a clue.

  1. Correct! I think the NaF gave it away for many people. I’ll have to come up with a harder one next week.
