Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to a whitening and repairing mask and a preparation method thereof.

Background

The facial mask mainly has the effects of cleaning and beautifying the skin, a layer of film is formed on the skin by smearing, after a certain period of drying, dirt, scurf and cutin of the skin can be washed away along with the washing of the facial mask, meanwhile, the facial mask can isolate the skin from the outside air, so that the temperature of the skin is increased, pores are expanded, and the skin can absorb nutrient components in the facial mask, improve the skin condition and achieve the effect of beautifying. Compared with other skin care product types, the facial mask has wider efficacy and quicker use effect. Therefore, the mask is more and more popular with consumers. The facial masks on the market at present mainly have four types according to the product form and the using mode: peel-off type, clay/gypsum type, cream type and face-patch type.

The release type facial mask is usually a transparent gel-like product, so the selection and the formulation of the film forming agent are key elements in the preparation of the release type facial mask, and the film forming agent with better film forming property and higher dispersion and application effects is generally selected. The powder material in the formula of the clay/gypsum type mask has larger specific gravity, and is white powder when being smeared, and the frequently added powder material is mainly pearl powder. The main formula of the cream type and face paste type facial mask also comprises four basic substances of a film forming agent, an emulsifier, a humectant, an effective component and the like. In addition to the above four mask types, there is a leave-on mask, also called a night-time mask, which has been recently originated from korea and causes a great fever in china, which has a property of being leave-on overnight because of its convenience in use and attractive appearance.

			EXAMPLE 1 group	224.36	159.67
EXAMPLE 2 group	223.98	156.43
			EXAMPLE 3 group	224.05	152.95
Comparative example 3 group	223.87	175.94
			Comparative example 4 group	224.15	189.27
Comparative example 5 group	223.58	182.46
			Comparative example 6 group	224.12	206.82
Comparative example 7 group	224.08	202.59
			Comparative example 8 group	223.78	178.24

As can be seen from table 2, the MI values of the skin melanin contents of the subjects using the whitening and repairing masks prepared in examples 1 to 3 of the present invention were significantly reduced, wherein the MI values of the skin melanin contents of the subjects using the whitening and repairing masks prepared in example 3 were most significantly reduced, and thus example 3 is the best example of the present invention; compared with the comparative examples 3-8, the subjects in the example 3 had lower MI values of skin melanin content, and thus it can be seen that the whitening and repairing mask provided by the present invention has a significant whitening effect.

Test example four evaluation of ultraviolet ray damage repairing Effect

1. Test samples: the whitening and repairing facial masks prepared in the examples 1, 2, 3 and 5-8 are prepared.

2. The test method comprises the following steps:

a balance test is adopted, the whitening and repairing facial masks prepared in the examples 1, 2, 3, 5, 6, 7 and 8 and deionized water are taken as test samples to prepare culture media and are divided into 12 groups, namely the group of the example 1, the group of the example 2, the group of the example 3, the group of the comparative example 5, the group of the comparative example 6, the group of the comparative example 7, the group of the comparative example 8 and a blank control group respectively.

3. And (3) test results:

the test results are shown in table 3.

Table 3: evaluation results of ultraviolet ray damage repairing Effect

As can be seen from table 3, the ATP content percentage and the protective rate of the groups of examples 1 to 3 are significantly increased compared to the blank control group, which indicates that the whitening and repairing mask prepared by the present invention has the effects of repairing ultraviolet injury and promoting cellular energy metabolism. The ultraviolet damage repairing effect was better in the example 3 group than in the comparative examples 5 to 8.

Claims
