Problems solved by technology

[0002] There are many compounds currently used for whitening and brightening, but the stability and safety of many raw materials with whitening effect are not very good. For example, whitening and brightening products containing vitamin C raw materials are generally very safe and mild, but after stopping After use, the melanin in the reduced state will slowly oxidize to normal melanin by itself, and high concentrations of vitamin C will be irritating to a certain extent, not stable enough, easy to oxidize, and be destroyed by light and decompose; whitening and brightening products containing kojic acid have A certain amount of irritation will weaken the skin barrier and the skin will lose moisture; some products will also weaken the skin barrier after excessively exfoliating the stratum corneum, making the skin less stable to light, easy to oxidize and change color; easy to interact with metal ions Chelated, less absorbed by the skin

preparation example Construction

[0099] The preparation method of the white willow bark extract is: after the white willow bark is cleaned and dried, pulverized and sieved, then soaked in ethanol, and then concentrated to obtain the white willow bark extract;

[0100] The preparation method of the citrus peel extract is: the citrus peel is cleaned and dried, pulverized and sieved, then soaked in ethanol, and then concentrated to obtain the citrus peel extract;

[0101] 1-Methylhydantoin-2-imide was purchased from: Zhenyue (Guangdong) Technology Research and Development Co., Ltd.

[0102] In the embodiment of the present invention, in parts by weight, the composition is composed of the following components: 10-25 parts of the leaf root extract, 3-5 parts of acetylchitosamine, 2-5 parts of white willow bark extract, 5-15 parts of citrus peel extract, 5-10 parts of 1-methylhydantoin-2-imide.

[0103] The ingredients of the composition are combined with each other, which has strong anti-oxidative ability, inhibi...

experiment example 1

[0117] Experimental Example 1 Determination of Antioxidative Capacity of the Extract of Roots and Leaves

[0118] 1. Antioxidant component analysis of the extracts of roots and leaves

[0119] In this experimental example, the antioxidant components of the extracted Radix officinalis leaf extract were analyzed, and the analysis results are shown in Table 1.

[0120] Table 1 The main antioxidant components of the root and leaf extract

[0121]

[0122] From the test results, it is confirmed that the root and leaf extract does contain antioxidants, which have antioxidant effects and can reduce the chance of free radicals attacking the lipids between the keratinocytes.

[0123]2. Determination method of antioxidant capacity DPPH free radical scavenging ability: DPPH is a purple-black free radical solution with the highest absorbance value at a wavelength of 517 nm. After reacting with hydrogen ions or electrons, its color will become light. Yellow, which reduces the absorban...

experiment example 2

[0130] Experimental example 2 Determination of whitening efficacy of acetylchitosamine

[0131] In this experimental example, the effect of different levels of acetylchitosamine organic components on the melanin of human cultured skin was determined by epidermal cell experiment (ex-vivo), and the group without NGA was used as the blank control group, containing 1.0% NGA and 3.0% NGA. NGA and the group containing 6.0% NGA are the experimental groups, which act on the human cultured skin, and detect the changes of melanin in the human cultured skin after the experiment.

[0132] figure 1 The results of the determination of the change of the melanin content of the cells by the extracts of the leaves of Radix officinalis are shown. like figure 1 As shown in the figure, the blank control group without NGA could not reduce melanin, and the blackness of the experimental groups showed different degrees of reduction. Among them, the group containing 3.0% NGA had the greatest effect ...

Abstract

The invention discloses a composition and a preparation method and application thereof, and cosmetics. The composition specifically comprises 10-25 parts of an Air-plant leaf extract, 3-5 parts of acetyl glucosamine, 2-5 parts of a Salix alba bark extract, 5-15 parts of a citrus peel extract and 5-10 parts of 1-methylhydantoin-2-imide. The composition has excellent skin brightening and whitening effects, effectively prevents skin oxidation, makes the skin tender and white, mildly improves the skin, and has the effects of keeping the skin moist, bright and smooth and preventing the skin from being dry and dark.

Description

technical field [0001] The present invention relates to the technical field of cosmetics, in particular to a composition and its preparation method, application and cosmetics. Background technique [0002] At present, there are many compounds used for whitening and brightening, but the stability and safety of many raw materials with whitening effect are not very good. For example, whitening and brightening products containing vitamin C raw materials are generally very safe and mild. After use, the melanin in the reduced state will be slowly oxidized to normal melanin by itself, and when the vitamin C concentration is high, it will be irritating to a certain extent, not stable enough, and easily oxidized and decomposed by light damage; whitening and brightening products containing kojic acid include: A certain degree of irritation will weaken the skin barrier and the skin will lose moisture; some products will also weaken the skin barrier after excessive stratum corneum remov...
