a little more google and this came up.
http://experts.about.com/q/2460/2671970.htmsodium percarbonate/sodium carbonate mix which is a stabilized mix of
sodium carbonate and hydrogen peroxide with extra sodium carbonate
thrown in. Hydrogen peroxide is released when you add it to water.
Sanitize? For food, I doubt it has been approved and may not be
strong enough. For general cleaning, it really would not work on many
things. It is better for spots not crud removal. Doesn't work at all
on oil/grease. If you search www.google.com for sodium percarbonate
you will find info from various suppliers.
