Out of intererest, just to broaden my understanding, could you comment further on what constitutes iron in solution? I imagine this could be found in spring/non-ionised water etc. How about the use of an iron containing compound such as brown algae in a product? Would that lend iron in solution to the mix? If so would a chelator bind this from reacting with sodium benzoate contained in another product layered on top? Kind thanks for educating me.

Thank you both.

For clarification, the iron oxides in the products are CI 77492, CI 77491 and CI 77499.

Thank you Bob! It all seems rather obvious now, I’m relieved and have purchased the scales you suggsted. 

Proteasyl looks interesting, I am in the U.K so buy my goodies online. Can anyone recommend a source?

I can’t even begin to thank you guys! If I could buy you a beer I would! Really nice of you to take the time to help. This makes it a great deal more clear to me! THANK YOU!
