Look now - oxygen is a gas of diatomic molecules. In fact, it makes up 21% of the air. The so-called "active oxygen" is also a gas, but consisting of individual oxygen atoms. They are so reactive that in practice they cannot be released as a gas in the free state, but react immediately upon receipt. And they are obtained from preparations that RELEASE active oxygen. These are bleach (a solution of sodium hypochlorite in water), hydrogen peroxide (30% is called perhydrol, 3% is called oxygenated water), even chlorine dissolved in water releases active oxygen. Now, it is probably a preparation that releases "soft" active oxygen, ie it releases it slowly and in small amounts. In this way he manages to do his job, arranging the tissues minimally. Such preparations can be dozens, with a variety of trade names. But to say simply "active oxygen" is, to put it mildly, meaningless. That and "poured" - ha-ha ... It's like saying "low pH" - well, it can be brought in any way, buffered or not. If you do not know exactly who the preparation is, which company it belongs to, are there similar other preparations, etc. - you are just wasting your time, as well as ours.

Hydrogen peroxide from the pharmacy 30%. Be careful not to burn yourself. This is active oxygen. It costs pennies. I am convinced that they sold you this for a lot more money. But when you don't understand simple chemistry, you're stuck. In addition, it only whitens and after a few washes damages the tissues.
