Hydrogen Peroxide White Spots Reason
The reason why hydrogen peroxide leaves white spots
Hydrogen peroxide often leaves white spots in things, and there are many differences in people. Why is it safe?
Hydrogen peroxide has strong oxidizing properties. When it is encountered, its molecules are easily cracked, releasing reactive oxygen atoms. This reactive oxygen atom is extremely active and can chemically react with many substances.
If it acts on fabrics, the color of fabrics is mostly derived from dyes. Dyes often contain chromophore groups. When reactive oxygen atoms meet chromophore groups, they can break their structure. The chromophore group is bad, the color of fabrics becomes lighter, and even white spots.
As for wood, stone and other substances. Wood contains cellulose, etc., and stone has various minerals. The reactive oxygen species of hydrogen peroxide either oxidizes and decomposes cellulose, or chemically reacts with minerals, causing the structure of the surface material to change. This change in structure makes light reflection and absorption different from normal places, resulting in white spots.
Or on the surface of the metal, although the metal is resistant to corrosion, the strong oxidation of hydrogen peroxide may cause an oxide film on the surface of the metal. This film is different from the original metal surface in light reflection, and also shows the appearance of white spots.
In short, hydrogen peroxide leaves white spots, and the cover is chemically reacted with the components in the material, causing the surface physical and chemical properties of the material to change, resulting in white spots.
