Background
The whole body moisture of a person is mainly stored in skin, and various skin problems such as dryness, dullness, roughness and the like can be caused when the skin is in a water shortage condition. And with the improvement of living conditions and working demands, people are in a closed air-conditioning room for a long time, which can lead to the acceleration of the evaporation of skin moisture and the physiological decrease of skin moisture with the increase of age. In addition, external environmental factors such as season exchanges have a great influence on skin moisture. Based on this, there is a great demand for skin moisturizing products.
Inonotus obliquus (Inonotus obliquus) belongs to Basidiomycotina, hymenomycetes, aphyllophorales, phanerochaeteceae, and is mainly parasitic under living standing tree bark of birch, silver birch, elm, alnus japonica, etc. or on stem of cut tree. It is mainly distributed in the northern hemisphere in the region of 45-50 degrees. Inonotus obliquus is mainly distributed in Changbai mountain area of Heilongjiang province and Jilin province in China. The research shows that the inonotus obliquus extract contains a plurality of active ingredients such as polysaccharide, triterpene, steroid, polyphenol and the like. In addition, the inonotus obliquus extract has remarkable antioxidant and anti-inflammatory effects, can improve the skin texture and reduce fine wrinkles, and has certain anti-aging and anti-wrinkle effects. Chinese patent CN117815096A discloses a moisturizing and repairing composition and application thereof, and discloses an inonotus obliquus extract with moisturizing effect.

10mg of the Inonotus obliquus extract prepared in examples 1-3 and comparative examples 1-3 was weighed and placed in a 50mL volumetric flask, and then dissolved, diluted and fixed to volume with ultrapure water until the volume was calibrated, and shaken uniformly to obtain an Inonotus obliquus extract sample solution.
2ML of each of the above sample solutions was taken, 2mL of a 5% phenol solution and 10mL of concentrated sulfuric acid were immediately added to each of the sample solutions, and mixed uniformly, and the mixture was subjected to constant temperature water bath at 80℃for 30 minutes, cooled to room temperature, and then absorbance of the samples was measured at 486nm wavelength, and each of the samples was measured three times, and the average was taken, and the polysaccharide content results in the Inonotus obliquus extract were shown in Table 1.
TABLE 1
As can be seen from the observation of Table 1, the polysaccharide content in the Inonotus obliquus extract prepared in examples 1-3 was higher, reaching more than 35.56 wt%.
The polysaccharide content of the Inonotus obliquus extract prepared in comparative examples 1-3 was reduced to a different extent than that of the Inonotus obliquus extract prepared in examples 1-3, wherein the polysaccharide content of the Inonotus obliquus extract prepared in comparative example 2 was the lowest, and was only 18.27wt%. In the process of the inonotus obliquus extract, synephrine is not added in the basic seed culture medium of the comparative example 1, shikimic acid is not added in the fermentation culture medium of the comparative example 2, and the culture medium of the comparative example 3 changes the adding time of the synephrine and the shikimic acid. From the above, in the process of the inonotus obliquus extract, the content of polysaccharide in the inonotus obliquus extract can be influenced by changing the usage amount and the adding time of synephrine and shikimic acid.
The effects of adding the moisturizing compositions of examples 1 to 3 and comparative examples 1 to 3 of the present invention will be described below.
The skin care product consists of the following raw materials in percentage by mass:
Carbomer 0.2%, PEG-40 hydrogenated castor oil 5%, behenyl alcohol 0.7%, each of the moisturizing compositions described above 3%, the balance being water.
Test example 2
Skin irritation of skin care products obtained by adding the moisturizing compositions of examples 1 to 3 and comparative examples 1 to 3 was detected by using 2015 "cosmetic safety technical Specification" as a reference standard, and the specific procedure is as follows:
Subjects were selected from 120 subjects aged 18-45 years, and randomized into 6 groups with a 1:1 ratio between men and women.
The detection method comprises the steps of putting 0.02g of skin care products obtained by adding the moisturizing compositions of examples 1-3 and comparative examples 1-3 into spot testers respectively, covering the spot testers added with the test substances on the curved sides of forearms of the testers by using a non-stimulated cloth-based adhesive tape, pressing the non-stimulated cloth-based adhesive tape by using palms to uniformly adhere the non-stimulated cloth-based adhesive tape to the surfaces of the forearms of the testers, continuing for 24 hours, removing the spot testers for 30 minutes, and observing skin reactions after the indentations disappear. If the result is negative, the observation is carried out again 48 hours after the patch test, and the skin irritation detection result after 48 hours is shown in Table 2.
TABLE 2
From an examination of Table 2, it is clear that the moisturizing composition provided by the present invention is mild and non-irritating to the skin and safe to use.
Test example 3
The moisturizing effect of the skin care products obtained by adding the moisturizing compositions of examples 1 to 3 and comparative examples 1 to 3 was examined with reference to QB/T4256-2011, evaluation guidelines for moisturizing efficacy of cosmetics, and the specific procedure is as follows:
Subjects were selected from 60 healthy female subjects aged 18-45 years, randomized into 6 groups.
The temperature is 22 ℃ and the humidity is 50% in the tested environment, so that direct sunlight is avoided.
Test method all subjects began the test 30 minutes after entering the test environment. The subjects applied the moisturizing compositions of examples 1-3 and comparative examples 1-3 on their faces once a day, each morning and evening, and the skin moisture content was measured before use and after use of the skin care product 28d, respectively, and each data set is an average of the test results of the panel.
Wherein, skin hydration content change rate (%) = (skin hydration content after use of skin care product 28 d-skin hydration content before use)/skin hydration content before use×100%, and the results are shown in table 3.
TABLE 3 Table 3
The higher the value of the change rate of the skin hydration content, the better the moisturizing effect of the skin care product is indicated. From an examination of Table 3, it is apparent that the composition of the present invention has an excellent moisturizing effect. Specifically, after the skin care product 28d added with the moisturizing composition of the present invention is used, the skin hydration content variation rate reaches more than 68.47%.
The moisturizing effect of the skin care products added with the moisturizing compositions of comparative examples 1-3 was reduced to a different extent than those of examples 1-3. The improvement of the polysaccharide content can promote the moisturizing effect of the skin care product by combining the result of the polysaccharide content in the inonotus obliquus extract.
Finally, the above embodiments are only for illustrating the technical solution of the present invention, and are not limited thereto. While the basic principles and main features of the present invention have been described above with specific embodiments, modifications or substitutions may be made thereto without departing from the spirit of the invention as claimed.
