Looking for suppler of Bis(3-sulfopropyl)-disodium-sulfonate

I have some unique Cu applications (about all I can say) for which there is no specific Shipley or Enthone formulation. We are working with one of those companies, but are facing the task of having to do the development work ourselves. Given the fact that we must do development, doing so on known ingredients is compelling. I have been unable to locate a supplier of Bis(3-sulfopropyl)-disodium-sulfonate (C6H12Na2O6S4) "SPS" through internet searches and would appreciate information on a supplier. In addition I would like to know specifically what types of resonant quaternary nitrogen compounds are being used as brighteners/grain refiners.

Thanks,

There are Indian companies, including Alcatraz Chemicals, who can supply such materials Michael.

Proprietary addition agents are a huge and important business, and because of the anonymity typical of web sites such as this one, we resist printing formulations or replies to your closing question because there is no practical way to be assured that the postings are truly public domain as opposed to a trade secret being disclosed by a disgruntled employee or other illegitimate source posting with a fictitious name.

Thanks for the reply RE: Alcatraz Chemicals. I have located several micro-levelers in the public domain in the meanwhile, but was still unable to locate a source for SPS due to its _many_ chemical names.
