Dear Latif,

Here in the U.S.A., and in many other areas, the formulations of brighteners and other additives are very tightly held trade secrets. The suppliers have invested a fortune in them.

I doubt that anyone is going to help you, and we can only print references to literature, not actual formulas anyway, but a good starting point would be journal articles (Plating & Surface Finishing, Metal Finishing, Transactions of the IMF, etc.)

For nickel brighteners specifically, though, ASM Metals Handbook vol. 5 has a very good chapter on the subject. Good luck.
