Ferrous sulfate and copper sulfate suspension

Wanderer0 - 20-3-2019 at 18:26

Hello everyone,
I am new to this forum, and this is not precisely my field of expertise, but I'm hoping I could find some help on some things I'm currently working on.
Thanks for every helpful information.

Now, I'm reproducing an expired patent in a home setting. It involves the topical application of ferrous and copper sulphate salts.
The salts are to be dissolved in equal amounts up to total of 4g/100ml
The solution is to be left on skin for several hours.

I am unsure of the stability of ferrous ions in such a setting.
More confusing: the preferred pH is specified as ~9.0.
I have never had both salts in the same solution, and i have always had precipitate with ferrous suphate in water (unless there was an acid enviroment).
Is there a way to make a suspension instead of a solution so that applicaton is possible?
How is a base a preffered enviroment for the stability of the active substances?

Thanks in advance for any answers

What is this solution supposed to do to the skin?

(I should find a link on the expired patent. It expired 2 days ago)
It was supposed to cause dermal papilla inactivation, after unplucking hair from the follicle and applying it on the area for several hours. Several sessions were required.
The combination of copper and iron in salt form is presented as much more effective than iron salt alone.
Application of copper salt alone was found to have no effect.
Since both sulphates are in hydrate forms, I made a conclusion that a water solution is in question. (I might be wrong).
