Hydrogen Peroxide as a Bleaching Agent

H202 as a Bleaching AgentIn the late 20th century when it was discovered that chlorine based bleaching processes used in wood pulping and the paper industry were creating a serious dioxin hazard, chlorine compounds were replaced with hydrogen peroxide throughout the industry.

Additionally, hydrogen peroxide has long been recognized as an important and effective bleaching agent for fabrics as it does not damage the fibers of many fabrics in the same way that other more caustic and toxic chemical bleaches do.

Hydrogen peroxide is also an active ingredient in many hair bleaches and dyes.

Concentrations of hydrogen peroxide at 6 percent or higher are strong enough to cause bleaching, while lower concentrations can be very effective cleaning agents without a bleaching effect. Hydrogen peroxide is also used in bleaching natural products such as wood, wool, and other natural fibers.
