Examples
Embodiment 1-4
[0061] Embodiment 1-4: skin conditioning agent, it is prepared by the following method:
[0062] Step i, taking raw materials for screening, washing with water, infrared sterilization, and freeze-drying at -20-0°C to remove all water;
[0063] Step ii, taking 100 g of the raw material obtained through step i, adding an extraction solvent, raising the temperature to reflux, and distilling to obtain the extract;
[0064] Step iii, passing the extract through a chromatographic column to obtain a skin conditioning agent with a purity ≥ 99% by weight;
[0065] The substance information of Examples 1-4 is shown in Table 1.
[0066] Table 1 Material information statistics of Examples 1-4
[0067]
Embodiment 5-7
[0068] Embodiment 5-7: the first sunscreen composition, it is prepared by the following method:
[0069] Step i, pulverizing all the raw materials to a particle size range of 10-50 μm;
[0070] Step ii, stirring and mixing the pulverized raw materials, and pulverizing again to obtain a first sunscreen composition with a particle size ranging from 5 to 50 μm;
[0071] The raw material information of Examples 5-7 is shown in Table 2.

[0073]
Embodiment 8-10
[0074] Embodiment 8-10: the second sunscreen composition, which is prepared by the following method:
[0075] Step i, taking titanium dioxide and pulverizing it until the particle size ranges from 5 to 50 μm;
[0076] Step ii, taking silicon dioxide and pulverizing it, adding water and sonicating until the particle size ranges from 5 to 50 μm, and spray-drying to the outer layer of titanium dioxide treated in step i;
[0077] Step iii: Take dimethylsiloxane and grind it, add water and ultrasonically sonicate until the particle size ranges from 5 to 50 μm, and spray dry to the outer layer of the silicon dioxide treated in step ii to obtain the second silicon dioxide with a particle size range from 5 to 50 μm. Two sunscreen compositions;
[0078] The raw material information of Examples 8-10 is shown in Table 3.
