Q: I know that regular chlorine bleach is not green and I avoid using it. But what about non-chlorine bleach? What is it exactly, and is it safe to use?
Asked by Tammi
Editor: While standard chlorine bleach is a 5.25% solution of sodium hypochlorite solution in water, non-chlorine bleach is made up of other chemical compounds like hydrogen peroxide, sodium percarbonate or sodium perborate that can also whiten clothes through oxidation. The oxidizing (or whitening) power isn't as effective as chlorine bleach, which is why non-chlorine bleach is usually listed as "color safe." But it's definitely more eco-friendly.
