Embodiment 1-7 and comparative example 1-5

[0026] The components of the sunscreen compositions of Examples 1-7 and Comparative Examples 1-5 are shown in Table 1, wherein the composition ratio is Snow Lotus extract, Hippophae rhamnoides fruit extract, Scutellaria baicalensis root extract, Tibetan calamus extract and water The mass percentage ratio of the silybum seed extract, that is, the component distribution ratio, is snow lotus flower extract: seabuckthorn fruit extract: scutellaria baicalensis root extract: Tibetan calamus extract: milk thistle seed extract, and water is the balance.

[0027] The preparation method of embodiment 1-7 of the present invention and comparative example 1-5 sunscreen composition is:

[0028] (1) Dry the snow lotus flower and grind it, then use 80% ethanol solution to reflux extraction at 100°C for 1 hour, extract twice, combine the extracts, then carry out vacuum distillation and concentration of the extracts to obtain the snow lotus flower extract ;

[0029] (2) Dry the milk thistle se...

Abstract

The invention discloses a sunscreen composition and a preparation method and application thereof, and belongs to the technical field of cosmetics. The sunscreen composition is prepared from the following components in percentage by mass: 1%-5% of saussurea involucrata extract, 0.5%-2.5% of fructus hippophae extract, 0.1%-1% of radix scutellariae extract, 0.1%-2% of rhizoma acori calami extract, 0.1%-1% of silybum marianum seed extract and the balance of water. According to the sunscreen composition, various plant extracts are compounded, all the components play a synergistic role, effective absorption of full-wave-band ultraviolet rays can be achieved, and the sunscreen composition further has efficient anti-oxidation and whitening effects.

Description

technical field [0001] The invention relates to a sunscreen composition and its preparation method and application, belonging to the technical field of cosmetics. Background technique [0002] Ultraviolet rays are divided into UVC (200-280nm), UVB (280-320nm) and UVA (320-400nm) according to wavelength. Among them, ultraviolet rays that can pass through the atmosphere and reach the ground are UVB and UVA. UVB can penetrate the stratum corneum and epidermis. It is the cause of most skin diseases and the culprit of sunburn. In mild cases, skin redness occurs, and in severe cases, erythema and blisters occur; while UVA generally does not cause inflammation, but the damage to the skin is cumulative. , causing long-term, chronic damage. According to the 1993 U.S. Sunscreen Trial Final Monograph (TFM) and the U.S. National Institute of Health, animal experiments have shown that both UVB and UVA have shown carcinogenic effects on the skin, but the former has a stronger effect; whe...
