Got my STPP in the mail today. It's a bit more pure than the stuff in your pic, but most likely will have the same results. I'm doing a load now. Fyi, it seems to cut down the suds level, which is a plus in my book.
You can see the suds level in this video. Without the STPP, there are about twice the suds.
