[0056] Test Example 1: Foaming Performance Test

[0057] The amount of foam has a certain indicative effect on the cleaning ability. When the facial cleanser comes into contact with the skin, the hydrophilic end of the surfactant in the water is distributed in the water, and the hydrophobic end is combined with the dirt. Multiple surfactant molecules wash the dirt off the skin surface, wrap it up, and rinse it away with water to play a cleaning role. When the skin is oily and the amount of foam is insufficient, it will not be able to remove all the dirt, which is manifested as insufficient cleaning power. When the foam is thick and delicate, it can increase the contact area with the skin and exert better cleaning ability. Therefore, the appropriate amount of foam can exert better cleaning ability.

[0058] Test method: The foam test method refers to GB / T 29679-2013 "Shampoo, Shampoo Cream". Preparation of facial cleanser sample solution: Use a 500ml beaker to weigh 1g facial cleanser, add 450ml deionized water and 50ml hard water, stir with a glass rod to dissolve evenly, use HH-2 digital display constant temperature water bath pot (Changzhou Aohua Instrument Co., Ltd.) to heat to (40±1)℃ for use. Use Roche foam meter to test the foam height of the facial cleanser samples of Examples 1-3 and Comparative Examples 1-9 at 0min, 1min and 5min. The test results are shown in Table 2.

[0062] The facial cleansers prepared in Examples 1-3 have better foaming properties and foam stability, wherein the foam height of the facial cleansers prepared in Example 3 can reach 51 mm, the foam is dense, the foaming properties are good, and the foam reduction rate after 5 minutes of foaming is not higher than 7.8%, indicating good foam stability. Compared with Example 1, the surfactant components or ratios of Comparative Examples 1-3 are different, and the foam height is 13-23 mm. The surfactants formulated in Example 1 have better foaming properties and foam stability; compared with Example 1, the moisturizer components or ratios of Comparative Examples 4-6 are different, and the foam height is 38-43 mm, with better foaming effects, but the foam reduction rate after 5 minutes of foaming reaches 21%, and the foam stability is poor, indicating that the addition of polyamino acid polysaccharide condensation products and shea butter is beneficial to improving the foam stability of the facial cleansers; compared with Example 1, the skin conditioner components or ratios of Comparative Examples 7-8 are different, and the foam height is 44-46 mm, and the foaming effect is comparable to that of Example 1, but the foam reduction rate after 5 minutes reaches 18 .18%, the foam stability is poor, indicating that the addition of Salix willowii extract, Prunus amygdalus extract, Chamaecyparis obtusifolia extract, and lactic acid bacteria fermentation lysate is beneficial to improving the foam stability of the cleanser; compared with Example 1, the content of caprylyl glycol and butylene glycol in Comparative Example 9 is different, the foam height is 37 mm, the foaming effect is slightly worse than that of Example 1, and the foam reduction rate after 5 minutes is 21.62%, and the foam stability is poor, indicating that the content of caprylyl glycol and butylene glycol may affect the foaming and foam stability; compared with Example 1, no aescin is added to Comparative Example 10, the foam height is 38 mm, and the foam reduction rate after 5 minutes is 13.16%, the foaming and foam stability are good, indicating that aescin can coordinate and enhance the foaming effect.

[0063] Test Example 2: Efficacy Evaluation

[0064] Subjects: 130 female volunteers aged 25-45 were recruited and evenly divided into 13 groups, with 10 people in each group.

[0065] Test method: Each group of volunteers cleansed their face once at 7 am and once at 9 pm every day for two weeks. The volunteers directly used the test product. Before use, they wet their face with warm water, squeezed out an appropriate amount of facial cleanser on the palm, added a small amount of clean water and rubbed it to produce rich foam. After massaging the face for 30 seconds, they rinsed it with clean water. The evaluation indicators such as the degree of cleansing, moisturizing degree, and skin surface residue after cleansing were scored, and the results were statistically analyzed and the average score was taken. The results are shown in Table 3.

[0066] Scoring criteria:

[0067] Cleanliness level: 5 points means very clean; 4-5 points means clean; 3-4 points means fair; and less than 3 points means unclean.

[0068] Moisturizing degree: 5 points means very moisturizing; 4-5 points means moisturizing; 3-4 points means average; less than 3 points means not moisturizing.

[0069] Skin surface residue: 5 points means no residue at all; 4-5 points means basically no residue; 3-4 points means fair; less than 3 points means obvious residue.

[0071]

[0072] The subjects did not experience discomfort symptoms such as allergies, red and swollen papules, and itching, indicating that the mild and moisturizing facial cleanser of the present invention is non-irritating to the skin and is mild and safe.

[0073] As can be seen from Table 3, the mild and moisturizing cleanser prepared in the examples of the present application has good cleaning and moisturizing abilities, is easy to rinse, and does not remain on the skin surface.

[0074] The cleaning ability and moisturizing ability of Comparative Examples 1-10 are weaker than those of Example 1, indicating that the surfactants, moisturizers, and skin conditioners of the present invention can enhance the cleaning effect and moisturizing effect. The facial cleanser using the formula of the present invention can obtain a better ability to remove grease and dirt on the skin surface, provide nutrients to the skin, improve the water-oil balance, make the skin smooth and translucent, and obtain a healthy skin state.

[0075] The facial cleanser of the present invention is added with polyamino acid polysaccharide condensation product, shea butter, salix alpiniae extract, sweet almond extract, cypress leaf extract, lactic acid bacteria fermentation lysate and aescin. Among them, the polyamino acid polysaccharide condensation product contains a variety of active ingredients, which can moisturize, stabilize, improve skin color, resist aging, resist oxidation, and nourish cells, so that cells absorb more water and become full and elastic; it helps epidermal absorption, and can also control the acid-base balance of the skin, actively prevent wrinkles, deeply nourish, and whiten the skin. Shea butter has very good moisturizing and emollient effects. The salix alpiniae extract component is suitable for seven types of skin, namely dry skin, oily skin, firm skin, pigmented skin, non-pigmented skin, wrinkled skin, and sensitive skin, and can resist inflammation and soothe the skin. Sweet almond extract is rich in nutrients, including vitamin A, vitamin B6, fatty acids, minerals, proteins and other ingredients. It is easily absorbed by the skin and has super hydrating and moisturizing ability. At the same time, it can effectively reduce itching, redness, swelling, dryness and inflammation of the skin, and has soothing and anti-allergic effects. Chamaecyparis obtusifolia leaf extract has anti-inflammatory, antioxidant, anti-allergic, wound healing and skin texture improvement effects. Lactobacillus fermentation lysate contains peptidoglycan, teichoic acid, protein, phospholipids, fatty acids, various enzymes, peptides and amino acids, nucleotides, extracellular polysaccharides and other active substances, which provide rich nutrition for the skin, have good anti-aging effects, and can regulate the ecological balance of the skin. Aescin is mild and biologically active, with good penetration ability, and has the effects of cleaning, moisturizing, anti-inflammatory, antioxidant, anti-allergic, promoting blood circulation, and repairing the skin barrier.

[0076] In summary, the surfactants formulated in the present invention are combined with polyamino acid polysaccharide condensates, shea butter, willow leaf extract, almond extract, cypress leaf extract, lactic acid bacteria fermentation lysate and aescin to achieve better cleaning effects and nourishing abilities, balance the skin ecology and make the skin healthier.
