Bluing content?

Considering using cold bluing for a project but can't seem to find what's actually in the product I have in mind.

Does anyone know, maybe someone who has seen the back of this product and knows what it says?

I have tried that product, and you might as well use narvsvärta; it has just as poor an effect as that product on metal surfaces.

When doing a proper bluing, you force a chemical reaction using various chemicals. Cold bluing is more like painting the surface with volatile paint.

Are you aware of the ingredients?
