Yes . It has been tested in labs and it is approved .
Hydrogen peroxide (H2O2), breaks down into water and oxygen. The oxygen created is a gas, so it bubbles out of the liquid. Since there's soap in the mixture for the elephant toothpaste reaction, the bubbles get trapped, making the foam.
The bubbles could be viewed as a sign that the peroxide is "eating" the bacteria. You will notice after a while that fewer and fewer bubbles appear, that is because the bacteria is getting killed.
Hydrogen peroxide (H2O2) is always decomposing to release oxygen and water, but it does so slowly. In elephant toothpaste, the hydrogen peroxide is mixed with detergent and food color and then saturated iodide solution is added. The iodide acts as a catalyst so that the H2O2 breaks down really quickly. All the gas bubbles released makes the detergent bubble up suddenly.
Little bubbles form around it...
When the catalase comes in contact with hydrogen peroxide, it turns the hydrogen peroxide (H2O2) into water. The bubbles you see in the foam are pure oxygen bubbles being created by the catalase.
The hydrogen peroxide, H2O2 , is being decomposed into water and oxygen gas (the bubbles).
The substance that changes is the hydrogen peroxide. After it reacts, it forms bubbles of oxygen and water.
When hydrogen peroxide bubbles when its pored on an open wound, is because it is cleaning out all of the germs and infection.
The white you see is many microscopic bubbles of oxygen released by a reaction between the Hydrogen Peroxide (H2O2) and your saliva.
Putting peroxide on a blood stain on fabric, it will bubble because of the reaction called catalase. After putting on the peroxide, cold water will help bring stain to the surface.
It has a cooling effect while it works and bubbles.
The enzyme is catalase. It can exist without adding hydrogen peroxide. The hydrogen peroxide simply activates the enzyme.
