Description

Whitening and moisturizing mask and preparation method thereof

Technical Field

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

Background

Among beauty cosmetics, facial masks are one of the earliest. The facial mask temporarily isolates outside air and pollution by using a short time of covering the facial mask, so that the temperature of the skin is increased, pores of the skin are expanded, the secretion and metabolism of sweat glands are promoted, the oxygen content of the skin is increased, products of metabolism of epidermal cells and accumulated grease substances are favorably discharged by the skin, water in the facial mask permeates into the horny layer of the epidermis of the skin, and the skin becomes soft. The skin is natural, bright and elastic.

Ceramides, also known as sphingolipids, are lipids present in the skin, play an important role in the formation of the stratum corneum of the epidermis, and are important roles in the physical barrier of the skin. Ceramides play the following important roles mainly in the stratum corneum of the skin: (1) ceramide is filled in the skin keratinocyte gap, so that water in the skin cannot permeate out, and excessive foreign matters cannot permeate into the skin, and the ceramide has a barrier protection function; (2) ceramides can maintain skin moisture by forming a network in the stratum corneum, which can prevent skin moisture loss; (3) ceramide has effects of improving symptoms such as facial dryness, flush, cosmetic infection, etc., and inhibiting melanin generation, and has obvious skin caring effect; (4) the ceramide skin care product can obviously thicken the horny layer of the skin, effectively inhibit skin allergy caused by the invasion of harmful substances and enhance the adaptability of the skin to the external environment. The ceramide is added into the facial mask as a raw material, so that the whitening and moisturizing effects of the facial mask can be improved, but in the actual production, the ceramide is poor in solubility and stability in the facial mask, and the effect of the ceramide is influenced. Therefore, the method for promoting the dissolution and the stability of the ceramide in the facial mask is provided, and the method has great significance in the field of cosmetics.

The following performance tests were performed on the masks prepared in examples 1 to 7 and comparative examples 1 to 3:

1. and (3) microbial detection: items such as total bacteria, total mold/yeast, heat-resistant coliform group, staphylococcus aureus and pseudomonas aeruginosa in the mask samples prepared in examples 1 to 7 and comparative examples 1 to 3 and the samples stored for 30 days were detected according to the method specified in technical specification for cosmetic safety (2015), and the detection results are shown in the following table:

TABLE 1 results of microbiological examination of masks prepared in examples 1 to 7 and comparative examples 1 to 3

TABLE 2 microbial test results of masks prepared in examples 1 to 7 and comparative examples 1 to 3

As can be seen from the data in table 2, the total number of bacteria in the mask products of examples 1 to 7 and comparative examples 1 to 3 is less than 10/mL, the total number of mold/yeast is less than 10/mL, and heat-resistant coliform group, staphylococcus aureus and pseudomonas aeruginosa are not detected, and meanwhile, the total number of bacteria, mold/yeast, heat-resistant coliform group, staphylococcus aureus and pseudomonas aeruginosa in the samples of the masks of examples 1 to 7 after being stored for 30 days are not changed, and the results of microbial examination show that the masks meet the requirements of technical cosmetic safety standards (2015 edition), which indicates that the masks prepared by the invention are safe and reliable. .

Compared with the mask solutions of examples 1 to 7, the total number of bacteria and the total number of mold/yeast of the mask of comparative examples 2 to 3 are increased in a sample after the mask solution is stored for 30 days, so that microorganisms are easily bred in the mask of comparative examples 2 to 3 in the storage process, and the storage is unstable, because polyphosphoric acid complex salt and polyacrylic acid are not added in the formula of the mask of comparative example 2, and glycyrrhiza glabra root extract, asiatic moonseed rhizome extract and herba violae extract are not added in the formula of the mask solution of comparative example 3, which indicates that polyphosphoric acid complex salt, polyacrylic acid, glycyrrhiza glabra root extract, asiatic moonseed rhizome extract and herba violae extract are compatible with each other, so that the growth of microorganisms such as bacteria, mold and yeast in the mask solution can be inhibited, the storage stability of the mask solution is improved, and the prepared mask solution is safe and reliable and is.

2. Selecting 100 female volunteers, wherein the female volunteers are 25-35 years old and randomly divided into 10 groups, each group comprises 10 individuals, measuring the brightness of the facial skin by a colorimeter, marking as L1, using the facial masks of examples 1-7 and comparative examples 1-3 respectively for each group, coating the facial masks on the whole face twice each day when in use, measuring the brightness of the facial skin by the colorimeter after coating for 4 weeks, marking as L2, calculating the color difference of the brightness of the facial skin after the facial masks of the examples and comparative examples are used, marking as △ L, and marking as L2-L1 for △ L, so as to evaluate the whitening effect of the facial masks of the examples and comparative examples, wherein when △ L is more than or equal to 2, the pigmentation is obviously relieved, and the whitening effect is achieved, and the test results are shown in the following table:

TABLE 3 whitening efficacy of masks prepared in examples 1 to 7 and comparative examples 1 to 3

Group of	ΔL
		Example 1	4.26
Example 2	4.35
		Example 3	4.32
Example 4	4.47
		Example 5	4.55
Example 6	4.38
		Example 7	4.43
Comparative example 1	0.39
		Comparative example 2	3.72
Comparative example 3	0.58

As can be seen from table 3, after the mask products of embodiments 1 to 7 of the present invention are used for 4 weeks, the chromaticity difference of the facial skin of the volunteers reaches 4.26 or more, which indicates that the mask products of embodiments 1 to 7 of the present invention can significantly improve the pigmentation of the facial skin, and have a good whitening effect.

Compared with the masks of examples 1 to 7, the mask products of comparative examples 1 and 3 have poor whitening effect, because the ceramide is added into the mask raw material of comparative example 1, and the ceramide nanoemulsion is not added, and the glabrous greenbrier rhizome extract, the asiatic moonseed rhizome extract and the herba violae extract are not added into the mask product of comparative example 3, which shows that the whitening effect of the mask can be remarkably improved by adding the ceramide nanoemulsion, the glabrous greenbrier rhizome extract, the asiatic moonseed rhizome extract and the herba violae extract into the mask product. Ceramide can inhibit melanin generation, promote skin metabolism, promote the exfoliation of melanin-containing keratinocytes, promote the synthesis of surface proteins, and improve skin texture, but ceramide has poor solubility and stability in facial masks, which affects the efficacy. The oil-in-water technology is adopted to prepare the ceramide into the nanoemulsion, and then the ceramide nanoemulsion is used as a raw material to prepare the mask, so that the solubility and the stability of the ceramide in the mask are remarkably improved, the exertion of the effect of the ceramide in the mask is effectively promoted, and the whitening effect of the mask is improved. The glycyrrhiza glabra root extract, the asiatic moonseed rhizome extract and the herba violae extract are mutually compatible, so that the activity of various enzymes in the melanin generation process can be effectively inhibited, and the whitening effect of the mask is further improved. It can be seen from the results of comparative examples 1 and 3 that the good whitening effect can not be achieved by using the ceramide nanoemulsion alone and using the glycyrrhiza glabra root extract, the asiatic moonseed rhizome extract and the herba violae extract alone, so that the whitening effect of the mask can be remarkably improved only by mutually matching the ceramide nanoemulsion with the glycyrrhiza glabra root extract, the asiatic moonseed rhizome extract and the herba violae extract.

3. Moisturizing effect: the moisture content of the skin stratum corneum is measured according to a capacitance method specified in QB/T4256-2011 'guidelines for evaluating moisturizing effects of cosmetics'. During testing, 100 female volunteers are selected, the female volunteers are 25-35 years old and randomly divided into 10 groups, 10 persons in each group are detected, the positions of the detected persons are the inner sides of the forearms of the two hands of the detected persons, a use area and a blank control area are divided before use, the facial masks prepared in the embodiments 1-7 and the comparative examples 1-3 are respectively used in the use areas of all groups, the blank control group is not treated, the moisture content of the stratum corneum is respectively tested on the use areas and the blank control areas by using a skin moisture tester before use and after use for 4 hours, and the test results are shown in a table 4:

TABLE 4 moisture retention test results of the masks of examples 1 to 7 and comparative examples 1 to 3

Group of	Moisture increment value (%)
		Blank control group	0
Example 1	11.6
		Example 2	11.3
Example 3	12.2
		Example 4	12.3
Example 5	12.8
		Example 6	12.4
Example 7	12.2
		Comparative example 1	3.6
Comparative example 2	5.8
		Comparative example 3	10.7

The data in table 4 show that after the facial masks of examples 1 to 7 are used for 4 hours, the moisture increase of the skin stratum corneum is remarkably improved, and the moisture increase value is as high as 13.7%, which indicates that the facial masks prepared in examples 1 to 7 have good moisturizing and moisturizing effects and meet the use requirements of consumers.

Compared with the facial masks of examples 1-7, the moisture value of the stratum corneum of the skin after 4 hours of using the facial mask liquid of comparative examples 1-2 is slightly increased, because the ceramide is added into the raw material of the facial mask of comparative example 1, the ceramide nanoemulsion is not added, and the polyphosphoric acid complex salt and polyacrylic acid are not added into the facial mask product of comparative example 2, which shows that the ceramide nanoemulsion, the polyphosphoric acid complex salt and the polyacrylic acid interact with each other, and the moisturizing effect of the facial mask liquid is obviously improved. Polyacrylic acid and polyphosphate are mutually compatible and can form a hydrated adhesive film when being used on the surface of skin, a moisturizing environment is provided for the skin, the dryness of the skin is relieved, on the basis, the ceramide nanoemulsion locks the moisture of the skin and prevents the volatilization of the moisture on the surface of the skin, and the three components are mutually compatible, so that the good water replenishing and moisturizing effects are achieved.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
