Abstract

The present invention provides a sunscreen composition, a sunscreen gel containing the same and a preparation method thereof. The sunscreen composition includes an ultraviolet absorber and a photoprotective additive. The ultraviolet absorber includes microsphere particles loaded with a chemical sunscreen agent. UV absorbers also include free chemical sunscreens; the sunscreen gel includes the sunscreen composition, thickeners, polyols, preservatives, pH regulators and water. The sunscreen gel can protect against UVA, UVB, HEV and IRA, prevent photoaging, improve the barrier function and resistance of the skin, make the skin moist and silky, mild and non-irritating, and avoid "sunscreen loopholes" when applying , has broad development prospects in the field of sunscreen and skin care products.

Description

technical field [0001] The invention relates to the technical field of cosmetics, and relates to a sunscreen composition, a sunscreen gel containing it and a preparation method thereof. Background technique [0002] Ultraviolet (UV) is part of the electromagnetic spectrum (light) that reaches the earth from the sun. The wavelength is shorter than visible light and invisible to the naked eye. According to the wavelength, ultraviolet rays can be divided into long-wave ultraviolet (Ultraviolet A, UVA), medium-wave ultraviolet (Ultraviolet B, UVB) and short-wave ultraviolet (Ultraviolet C, UVC), most of UVC is absorbed by the ozone layer and does not reach the earth. Scientific research has proved that excessive exposure to ultraviolet rays can damage the human immune system, accelerate skin aging, and lead to the occurrence of various skin diseases and even skin cancer. [0003] Blue light, also known as High Energy Visible Light (HEV), is light with a wavelength between 400-5...
