What exactly is non-chlorinated bleach? i was checking the tag of my clothes before i wash them...

i was checking the tag of my clothes before i wash them and all of them utter something like, 'use non-chlorinated bleach when needed' or something close to that
how is non-chlorinated bleach different from regular bleach?
[i mean i know there's no chlorine, but how does that affect my clothes?]

Answers:    Basically "oxygen" bleaches. Clorox II is a non-chlorine bleach (Clorox short the II is a chlorine bleach). There are other non-chlorine brands but that's the one that comes to mind first.

Looking for a good explanation of Oxygen Bleaches I found a to some extent article and have put a intertwine in sources below.

Its bleach that does not own chlorine in it.
