Buying Sodium Percarbonate for Laundry

June 25, 2023 11:50 AM

Where to purchase Sodium Percarbonate in the US? Question is inspired by this recent comment.

A nearly identical question is asked here with no answers for Sodium Percarbonate.

An internet search has led me to chemistrystore.com, any experience with this site or other retailers that sell Sodium Percarbonate (and not Sodium Carbonate or Sodium Bicarbonate)?

I already know about Oxiclean; I'm looking for something that isn't branded or diluted while also avoiding Amazon.

Best answer: If you live near a brewery supply store, they’ll have it in stock. Chemistrystore.com is legit, as are countless other online retailers. It’s a normal and not particularly profitable chemical, so you’re unlikely to run into many “scam” sites advertising it.

Best answer: I’ve ordered from chemistry store in the past and it was fine. I don’t remember exactly what I ordered, tbh, possibly mango butter, but in any case, I had no problems with them.

Sodium percarbonate is sold as "washing soda" in the states. E.g, "super" washing soda. If it's washing soda, it's sodium percarbonate

Washing soda is generally going to be sodium carbonate. Close to sodium percarbonate, but not the same.

The key difference between sodium carbonate and sodium percarbonate is that sodium carbonate is a single molecule whereas sodium percarbonate is an adduct of sodium carbonate and hydrogen peroxide. Furthermore, sodium carbonate is a white solid, whereas sodium percarbonate is a colourless crystalline solid.

Oxiclean is 50-60% sodium percarbonate.
