Description

Technical Field

[0001] The present invention relates to the technical field of sunscreen creams, and in particular to a children's sunscreen cream and a preparation method thereof. Background Art

[0002] Common children's sunscreen products on the market are mainly divided into the following categories: Using a combination of conventional sunscreens, this type of product is cheap and has a high sun protection factor, but because the small-fraction sunscreen has a certain permeability, it has certain safety risks.

[0003] A combination of macromolecular chemical sunscreens, including ethylhexyl triazone, bis-ethylhexyloxyphenol methoxyphenyl triazine, polysilicone-15, and diethylbutyramido triazone. This type of product has reasonable safety, but suffers from lower SPF and PA values.

[0004] Purely physical sunscreens, such as those made with non-nano titanium dioxide and non-nano zinc oxide, are safe, but suffer from poor feel, high resistance to application, and a discolored appearance that affects the skin. Therefore, a children's sunscreen and its preparation method are urgently needed to address these issues. Summary of the Invention
