What is oxygen bleach?

it is the common term for sodium percarbonate, a compound of natural soda crystals and hydrogen peroxide.

Hi Kathleen, Unlike traditional bleach, oxygen bleach uses much gentler sodium percarbonate to get the job done. When mixed with water, the simple contents break down to hydrogen peroxide—essentially water and oxygen plus sodium carbonate, or soda ash. This amazing product contains no phosphorous or nitrogen, making it a perfect eco-friendly choice. It is odorless and colorless and comes in both a liquid and powder form.

Oxyclean

It is a bleach product that is made without chlorine so it is not toxic and doesn't have any of the harmful effects. It is very effective at cleaning, however.
