Oxygen-providing material with the function of skin whitening

A material providing skin-whitening gas, wherein said material comprises a solid oxygen source, a solid activator, and a solid catalyst;

• wherein:
• the solid oxygen source is selected from the group consisting of calcium peroxide, magnesium peroxide, sodium peroxide, potassium peroxide, sodium percarbonate, and calcium percarbonate;
• the solid activator is selected from the group consisting of tetraacetyl ethylene diamine (TAED), sodium nonanoyloxy benzene sulfonate (NOBS), tetraacetyl glycoluril, pentaacetyl glucose, N-acetyl phthalimid, 1-acetyl ethyl benzoate, triacetyl ethanolamine, and nonanoyl acetyl phenyl tosylate;
• the solid catalyst is catalase;
• a solid mass ratio between the activator and the solid oxygen source ranges from 0.5:100 to 10:100;
• a mass ratio between the solid catalyst and the solid oxygen source ranges from 0.5:100 to 5:100;
• and the material can react with fluid to produce whitening gas;
• wherein a citric acid can be further added into the material, and the mass ratio between the citric acid and the solid oxygen source ranges from (5-8):(2-5);
• wherein the material is placed in skin-contact products.
