Geoff,
I will add my simpler take: If I don't know what is in a product I put into my pool, it doesn't go into my pool.
Coca-Cola may have a secret formula but it doesn't have secret ingredients. That is the object of the Pure Food And Drug Act signed by Teddy Roosevelt. So the analogy isn't valid.

When it comes to what I will recommend to our users, it is very simple. If I don't know what it is, I do not recommend it. For me, that is a line I simply will not cross. My children get into my pool, ingest some of the water, as we all do, and I will not have them ingest any unknown chemical. How well the product works, all the assurances of safety you can provide do not matter to me.

If I don't know what is in it, I won't use it. I won't recommend it.
