IARC Carcinogenicity Review: Suspected positive in animals. Wuxi hydrogen peroxide with higher concentration (more than 10%) is used in textile, leather, paper, and wood manufacturing industries as bleaching and deodorizing agents. Hydrogen peroxide is also one of the components of hair dyes, and is also used as a material for synthesizing organic raw materials (catechol), medicine, metal surface treatment agent, polymerization initiator, etc. Can also be used as rocket propellant. Industrial hydrogen peroxide is another hydrogen oxide besides water. The viscosity is slightly higher than that of water, and the chemical properties are unstable. Generally, it is stored in the form of a 30% or 60% aqueous solution, and its aqueous solution is commonly known as hydrogen peroxide. Hydrogen peroxide has strong oxidizing properties and is weakly acidic. Hydrogen peroxide manufacturers are mainly used for sterilization and external medical purposes, such as wound disinfection. The best ratio for testing blood: 6% hydrogen peroxide plus 0.005% methylene blue.

Hazardous properties

Explosive strong oxidant. Hydrogen peroxide is not flammable by itself, but can react with combustibles to release a lot of heat and atmosphere in China, causing fire and explosion. Hydrogen peroxide is most stable when the pH is 3.5 to 4.5, and it is easy to decompose in alkaline environment solution. It can also decompose in the presence of strong light, especially when irradiated with short-wave rays. When heated above 100°C, a sharp increase in decomposition begins to develop. It forms an explosive mixture with many of our research organics such as sugars, starches, alcohols, products of petroleum companies, etc., and information explosion can occur under impact, heat or electric sparks. Hydrogen peroxide and many traditional inorganic element compounds or impurities will decompose more rapidly after they are not in contact with society, resulting in a data explosion, releasing a large amount of heat, oxygen and water vapor. Most of these heavy metals (such as copper, silver, lead, mercury, zinc, cobalt, nickel, chromium, manganese, etc.) and their important oxides and salts are active as catalysts, dust, cigarette ash, carbon powder, rust etc. can also speed up work breakdown. Hydrogen peroxide with a concentration of more than 69% will produce a gas-phase explosion in a closed container with a certain appropriate ignition source or temperature.
