Problems solved by technology

[0003] In the prior art, ultraviolet absorbers are added to absorb the energy of ultraviolet rays, and then released in the form of heat or visible light, thereby reducing skin damage. However, many chemically synthesized ultraviolet absorbers are highly irritating to the skin, and some have poor air permeability. It is easy to clog the pores and affect the secretion of sweat glands

Embodiment 1

[0028] Preparation of barrier sunscreen composition:

[0029] Put 28.4 grams of white tea extract, 5.2 grams of bee pollen extract, 6.1 grams of seaweed extract, and 60.3 grams of deionized water in a mixer, stir and mix evenly to obtain the isolation sunscreen composition.

[0030] UV protection test:

[0031] It is determined by QB / T2410-98 "Measurement method for UVB sunscreen skin care effect of sunscreen skin care products - ultraviolet absorption ℃ method", and the relevant data are as follows in Table 1:

[0032] Table 1

[0033]

[0034] From the data in Table 1, it can be seen that the barrier rate of the isolation sunscreen composition of Example 1 to ultraviolet rays is significantly higher than that of TiO 2 , ZnO to the blocking rate of ultraviolet rays, it shows that the isolation sunscreen composition of the present invention has excellent anti-radiation effect.

Abstract

The invention discloses an isolated sunscreen composition which comprises an ultraviolet light absorbent, an antioxidant and a calming and soothing agent, wherein the ultraviolet light absorbent comprises one or more of a white tea extract, ultra-fine nanometer titanium dioxide, nanometer zinc oxide, ethylhexyl salicylate, butyl methoxy dibenzoyl methane and rutin. The isolated sunscreen composition disclosed by the invention has the beneficial effects that the ultraviolet light absorbent added in the isolated sunscreen composition can absorb ultraviolet light and reduce the damage caused by the ultraviolet light to skin; the antioxidant added can remove free radicals and reduce the oxidative damage; the calming and soothing agent added can clam and sooth the skin and strengthen the ability to protect against ultraviolet radiation; by cooperated use of all the components, the isolated sunscreen composition can realize a good isolated sunscreen effect and give cosmetics a significant isolated sunscreen effect when being applied to the cosmetics, so that the skin is better protected.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to an isolation sunscreen composition. Background technique [0002] Ultraviolet rays are very harmful to human skin. The "ultraviolet rays" in people's mouth can actually be subdivided into long-wavelength UVA, medium-wavelength UVB and short-wavelength UVC. When UVC enters the atmosphere, it has been protected by the ozone layer. Under the isolation, only UVA and UVB can radiate to the ground. UVB can be isolated as long as it is properly covered. It is the main cause of skin redness, inflammation and sunburn; UVA will be refracted into the room, also known as "indoor ultraviolet rays", which can penetrate deep into the dermis and damage collagen, elastic fibers and even Fibroblasts are destroyed, so UVA not only stimulates pigment synthesis and darkens the complexion, but is also the main culprit of skin aging and fine lines. The skin is exposed to ultraviolet rays for a long time, whi...
