Problems solved by technology

In my country's "Safety and Technical Specifications for Cosmetics" (2015 edition), there are 27 approved sunscreens, including 25 organic sunscreens and 2 inorganic sunscreens, but these are artificially synthesized chemical sunscreen structures, and these The ingredients usually only protect against ultraviolet rays in the UVB and UVA bands, and do not involve protection against near-infrared and visible blue light bands

Abstract

The invention relates to a plant sunscreen synergism combination and a preparation method thereof. The plant sunscreen synergism combination is characterized in that a hydrolyzed rice bran extract, a cistus incanus flower / leaf / stem extract, a tagetes erecta extract, a porphyra umbilicalis extract, a leontopodium alpinum extract, gamma-cyclodextrin and hydroxypropyl guar gum prepare into the plant sunscreen synergism combination according to the weight ratio of (3-5):(1-3):(1-3):(3-5):(3-5):(15-20):(5-10). The plant sunscreen synergism combination has the function of protecting near-infrared bands and visible blue bands and can enhance sunscreen effects of existing sunscreen preparations.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a plant-derived sunscreen synergistic composition and a preparation method thereof. Background technique [0002] Ultraviolet rays can be divided into UVC (short-wave ultraviolet, 200nm-290nm), UVB (medium-wave ultraviolet, 290nm-320nm) and UVA (long-wave ultraviolet, 320nm-400nm) according to their wavelengths. The UVC that reaches the ground after passing through the ozone layer is very weak, UVB is only partially absorbed by the ozone layer, and UVA is not absorbed at all. Therefore, the ultraviolet rays on the ground are mainly composed of 10% UVB and 90% UVA. UVB has a strong ability to act on the skin, and after irradiation, edema, blisters, erythema, peeling, and skin aging will appear. UVA has strong penetrating power and can reach deep into the dermis of the skin. It has a cumulative effect on the skin. Long-term exposure will cause skin browning, collagen fiber brea...
