Embodiment 1-5

[0033] Embodiment 1-5 and contrast 1-7

[0034] Examples 1-5 and Comparative Examples 1-7 provide a sunscreen composition with cell-level repairing effect and a preparation method thereof. The components and contents of the sunscreen composition are shown in Table 1. The preparation method of the sunscreen composition is as follows:

[0035] After the fresh green tea leaves are finished at high temperature, they are dried, pulverized and sieved. According to the ratio of green tea powder: water: ethanol = 1:10:10, ultrasonic extraction is carried out at 40°C for 30 minutes. The clarified liquid is obtained by filtration with a microporous membrane, and concentrated to obtain the green tea extract.

[0036] Brown algae extracts are used as raw materials, including Fucus serrata and Sargassum platensis, dried, pulverized and sieved, and ultrasonically extracted at 40°C for 30 minutes according to the ratio of seaweed powder: water: ethanol = 1:10:10, and left to stand After 3...

Embodiment 4

[0042] This embodiment is basically the same as the sunscreen composition and preparation method thereof in Example 1, except that the Qingxuan extract used in this embodiment is camellia seed oil (wt%): camellia flower extract (wt%): Camellia tea extract (wt%)=90:7:3.

Embodiment 5

[0044] This embodiment is basically the same as the sunscreen composition and preparation method thereof in Example 1, except that the Qingxuan extract used in this embodiment is camellia seed oil (wt%): camellia flower extract (wt%): Camellia tea extract (wt%)=98:1:1.

Abstract

The invention relates to a sunscreen composition with a cellular level repairing effect and application thereof. The sunscreen composition comprises the following components in percentage by weight of15-25% of camellia extract, 0.5-1.5% of green tea extract, 0.5-1.5% of of algal polysaccharides, 0.5-1.5% of glabridin, 0.5-1.5% of asiaticoside, 65-80% of water and 1-5% of emulsifier. The sunscreencomposition provided by the invention can repair skin injury caused by UVB from a cellular level, alleviates the phenomena of skin barrier damage, skin aging, erythema and the like caused by UVB, andcan also increase the sunscreen index of a sunscreen agent and improve the sunscreen effect of a product through a synergistic effect. Water-soluble and oil-soluble components are fused through an emulsification process, so that the application of active substances is facilitated, and in addition, the composition is mild in action effect, natural, safe and low in irritation.

Description

technical field [0001] The invention relates to the technical field of skin care products, in particular to a sunscreen composition and its application, in particular to a sunscreen composition with repairing effect at the cell level and its application. Background technique [0002] UVB (290-320nm) and UVA (320-400nm) are important factors leading to skin sunburn, photoaging and skin cancer. The UVB damage to the skin is 800-1000 times that of the same dose of UVA. Keratinocytes are located in the epidermis and are the first line of defense against ultraviolet radiation and the main target of UVB wavelength energy. UVB radiation can cause radiation damage to immortalized epidermal keratinocytes (HaCaT), resulting in the level of reactive oxygen species (ROS) and the generation of free radicals in skin tissue, as well as tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6). 6), which in turn causes a series of oxidative damage. UVB can also penetrate the epidermis to ...
