According to the test data of the experimental examples 1-3, the blank group and the control group in the table 3, after the test subjects use the facial cleanser prepared in the examples 1-3 to clean, the water content of the skin cuticle is greatly increased within 2min, and the water content loss rate of the skin cuticle is less after 30min and 60 min; after the common amino acid facial cleanser in the control group and the skin of the test person cleaned only by clear water, the increase of the water content of the skin stratum corneum of the test person is obviously weaker within 2min, and the loss rate of the water content of the skin stratum corneum is obviously increased after 30min and 60min, so that the facial cleansers prepared in the embodiments 1-3 have good permeability, can ensure that the skin can be absorbed by a large amount of nourishing substances within a short time, and can realize the effects of moisturizing and water locking for a long time.

As can also be seen from the comparison of the values of the skin elasticity change rate in table 3, the facial skin elasticity of the test subjects was significantly improved after 30 days of using the facial cleansers prepared in examples 1 to 3 of the present application, which further reflects that the facial cleansers prepared in examples 1 to 3 of the present application have better effects of promoting the recovery of skin elasticity and increasing the activity of skin cells.

The skin cleaning composition prepared in the preparation examples 1-3 is selected correspondingly in the examples 1-3, and the composition contains soapberry extract, tea polyphenol extract, honeysuckle flower extract, wild chrysanthemum flower extract, seabuckthorn fruit extract, tremella extract and seaweed particles; the skin cleansing composition containing the components is matched with other components in a facial cleanser system, so that the facial cleansers prepared in the embodiments 1 to 3 have better cleaning and skin care effects; the skin cleaning compositions prepared in the preparation examples 4 to 6 are respectively selected in the comparative examples 1 to 3, seaweed particles are not added in the preparation example 4, green tea raw materials are replaced by nettle in the preparation example 5, wild chrysanthemum flowers and tremella are replaced by honeysuckle flowers and pawpaw in the preparation example 5, and the components of the skin cleaning compositions in the preparation examples 4 to 6 are changed, so that the performance and the efficacy of the facial cleanser prepared in the comparative examples 1 to 3 are also influenced to a certain extent.

The skin cleansing composition 3 used in examples 1 to 3 contains various plant components including a soapberry extract, a tea polyphenol extract, a honeysuckle flower extract, a wild chrysanthemum flower extract, a sea buckthorn berry extract and a tremella extract, and the plant extracts can generate a good synergistic effect under a certain combination proportion, permeate into the deep layer of the skin to perform more sufficient cleansing and oil control on the skin and provide nourishment for skin cells; the seaweed particles have good lubricating and adsorbing capacity, the seaweed particles and the multiple plant extracts are fully mixed, in the process of rubbing and cleaning by using the facial cleanser, the seaweed particles rub the surface layer of the skin, the effect of removing grease dirt on the surface layer can be achieved, the cleaning capacity of the facial cleanser is improved, certain lubrication is achieved for the seaweed particles and the surface of skin cells by the composite plant extracts on the surfaces of the seaweed particles, the friction damage to the skin when the seaweed particles rub the skin is reduced, meanwhile, the composite plant extracts can permeate the bottom layer of the skin, and the skin is nourished while the facial skin is cleaned. In the process of the action of the substances, the substances are mutually matched and act synergistically to generate a remarkable technical effect, and the components are changed or lack in the comparative examples 1-3, so that the components are difficult to well cooperate to take effect, and the effects of cleaning, controlling oil, preserving moisture, locking water and nourishing and tendering skin of the facial cleanser prepared in the comparative examples 1-3 are reduced.

The skin activating agent prepared in the preparation example 9 is selected from the skin activating agent prepared in the embodiment 4, the skin activating agent is a commercially available firming skin activating agent NB-370, and the main component is rosemary leaf oil; in example 3, the skin-activating agent prepared in preparation example 7 was used, and in preparation example 7, the skin-activating agent was prepared from 78-80 wt% of lactobacillus/rice fermentation product, 15-20 wt% of sweet almond oil and the balance of 1, 2-pentanediol, and the skin-cleaning milk prepared in example 4 was used by a test person, and compared with the skin-cleaning milk prepared in example 3, the skin-cleaning milk prepared in example 3 showed better effects of oil control, moisture retention and water locking, and skin tenderness in skin oil content test, skin moisture content test and skin elasticity change rate test.

The stabilizing agents prepared in preparation examples 12 and 13 are selected in examples 5 and 6, respectively, the stabilizing agent prepared in preparation example 10 is used in example 3, the stabilizing agent in preparation example 10 is prepared from carbomer, arginine and xanthan gum according to a specific ratio, and the carbomer, arginine and xanthan gum can act synergistically, so that on one hand, the formation of a skin surface protective film can be promoted, the moisturizing and skin-tendering effects can be improved, on the other hand, a good suspension stabilizing effect can be achieved, components in the facial cleanser, particularly a skin cleaning composition, can maintain good compatibility stability in a system, and further the cleaning and skin care effects of the facial cleanser can be guaranteed; the proportion of the three ingredients in preparation example 12 is out of the limit range of the application, and preparation example 13 adopts myristyl decaglycerol as a stabilizer, compared with the myristyl decaglycerol as a stabilizer, the stabilizer prepared in the application can achieve better gain effect, so the performance of the facial cleanser prepared in example 5 is inferior to that of the facial cleanser prepared in example 3; the components in the stabilizer prepared by the method can generate better synergistic effect only by matching under a specific proportion, and the proportion breaks the limit, so that the performance and the efficacy of the facial cleanser prepared in the embodiment 6 are influenced.

In example 7, sodium myristoyl glutamate is selected as the amino acid surfactant, and compared with the amino acid surfactant prepared by compounding sodium lauroyl glutamate and sodium cocoyl glycinate in example 3, the compatibility of the sodium myristoyl glutamate with other components in the facial cleanser system of the present application is poor, so that the matching effect of substances in the system cannot be sufficiently exerted, and further, the efficacy of the facial cleanser prepared in example 7 is reduced.

In examples 8 to 10, the combination ratio of the skin cleansing composition and the skin activating agent in the facial cleanser system is further defined, so that the skin cleansing composition and the skin activating agent can exert a better synergistic effect, the skin absorption capacity of the skin can be improved in the facial rubbing process of the facial cleanser, the cleansing and oil control of the facial cleanser on the skin can be promoted, the active ingredients in the skin activating agent and the skin cleansing composition can interact with each other, a protective film is formed on the surface layer of the skin after facial cleansing, the long-acting water locking and moisturizing effect on the skin can be achieved, the skin is not tight and dry after the facial cleanser cleans the skin, the skin is long-term moisturized and smooth, and the facial cleansers prepared in examples 8 to 10 have better cleansing and oil controlling, moisturizing and water locking effects and nourishing and skin tendering effects compared with the facial cleanser prepared in example 3.

The proportion relation between the skin cleaning composition and the skin activating agent in the comparative examples 4 and 5 is greatly adjusted, the mutual effect of the skin cleaning composition and the skin activating agent in a facial cleanser system is directly influenced by the proportion adjustment between the skin cleaning composition and the skin activating agent, the mutual effect of the skin cleaning composition and the skin activating agent in the facial cleanser system is further hindered, particularly the gain of the skin cleaning composition and the skin activating agent on the cleaning oil control of the facial cleanser is prevented, and the facial cleansers prepared in the comparative examples 4 and 5 are difficult to maintain good cleaning oil control effect.
