What is the concentration hydrogen peroxide (H2O2) in glow sticks?

by Selma | Posted in Chemistry

What is the concentration hydrogen peroxide (H2O2) in incandescence sticks? I need to know for a science project and I can only find the make room-your-own-glow sticks concentrations. Does anyone know this, is this on the package deal of the glow sticks or anything?

30% H2O2 finding out. You can dilute H2O2 to slow the oxidation process, which will make your gleam stick glow less intensely but will continue to glow longer.
