## Abstract

The present invention provides an oxygen-providing material with the function of skin whitening, characterized in that said oxygen-providing material comprises a solid oxygen source, an activator, and a catalyst; wherein the solid oxygen source is selected from the group consisting of peroxide and percarbonate; wherein the oxygen-providing material with the function of skin whitening can be placed in household products, said household products comprising respirator, mask, facial mask, bra, chest paste, spill proof pad, sanitary napkin, diaper, panty liner, disposable hygiene product, band-aids, wrapping sponge, and box-shaped container.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The material according to claim 1, wherein the solid mass ratio between the activator and the solid oxygen source ranges from 2:100 to 3:100; wherein the mass ratio between the solid catalyst and the solid oxygen source ranges from 1.5:100 to 2.5:100.

### Claim 3 (depends on 1)

The material according to claim 1, wherein the material is in the form of particle, powder, or compressed powder, wherein the particle size of the material ranges from 2000 meshes to 2 mm.

### Claim 4 (depends on 1)

The material according to claim 1, wherein the skin-contact products comprising respirator, mask, facial mask, bra, chest paste, spill proof pad, sanitary napkin, diaper, panty liner, disposable hygiene product, band-aids, wrapping sponge, and box-shaped container.

### Claim 5 (depends on 1)

The material according to claim 1, wherein the whitening gas contains oxygen or reactive oxygen species (ROS).

### Claim 6 (depends on 1, 2, 3, 4, 5)

A skin-whitening structure, wherein the skin-whitening structure is a breathable package wrapping the material according to claims 1, 2, 3, 4 or 5, wherein a particle size of the material ranges from 2000 meshes to 2 mm, the breathable package contains small pores, a diameter of the small pores are less than the particle size of the material, and the diameter of small pores are larger than the whitening gas.
