Sodium Sulfate is not a foaming agent.
Based on Aircrete Harry's videoat about minute 5 on foaming agents I have been writing about buying sodium sulfate at a low cost.

Great video Harry. Regardless of quality, Sodium Sulfate does have some negative qualities ie. can cause cancer, eye irritant and mild skin irritant.
Now for some good news. You can buy a 50 pound pail for about $40.00. Shipping to where I live in WV adds another $23.00 which is still very cheap. Buy it at dudadiesel dot com.

Thank You I just ordered 50 lb.
Well since Harry bought it I did also. I just rec'd it 2 days ago. It doesn't foam at ALL.
@gemniii This sounds like a disappointing experience. I expect that there is much you are learning from it, and much that we could all gain from your experience. Would you please post a photo of the label or invoice for this product that you purchased? There are several products on the market with very similar names that are actually very different in their nature. If you would be willing, please post a photo so that we can see exactly what product and brand of product did not work as a foaming agent.
here's the link:
here's the "invoice"

Product Name: Natural Sodium Sulfate, 40 lb - FREE SHIPPING,
99+% Pure, Crystalline/Granular, Anhydrous (without water), Food

@gemniii Ok, thank you so much for sharing your hard lesson. We can all learn from this just as much or more than we can learn from our "success stories".
According to what I have read, Sodium Sulfate is definitely not a foaming agent, never has been. There is a lot of confusion around names in this area of terminology. Here's a basic breakdown:
- Sodium Lauryl Sulfate (SLS): a serious foaming agent used in thousands of household products
- Sodium Lauryl Sulfoacetate (SLSA): a milder foaming agent that is less artificial and less toxic - this is what Aircrete Harry was showing in his video
- Sodium Laureth Sulfate (SLES): Is used very similarly to SLS as a powerful foaming agent, but it is not a skin irritant like SLS
- Sodium Sulfate: an industrial salt
There are still more terms that I have not mentioned that are similar and could be confused, so I would say pay very close attention when discussing or purchasing these items.
So what I came to realize is that in the video where Aircrete Harry discusses the 4 foaming agents and recommends SLS is that the bag he has is different than the product info he printed off Amazon. I ordered off Amazon and just ordered what was on his printout in the video. But the video is only Sodium Sulfate (salt) and thus I had absolute no foam. So I have ordered actually SLS and will see how that goes. It was great to realize the source of the confusion and now I have hope again.. It was so discouraging to have no bubbles at all...
