That's not what this is. Sodium silicate is part of the process but so are lots of other things. The patent is posted here in the comments that would be a good place to start if one wanted to experiment with it.
No, it's basically just sodium silicate and fumed silica. The patent mentions lots of other things you could hypothetically substitute or add, but gives no indication that they've tried any of them — they just wanted to write the patent as broadly as possible. Some of the hypothetical ingredients mentioned in the patent don't seem to actually exist.
