Description

Technical Field

[0001] The invention belongs to the technical field of daily cosmetics, and relates to a surfactant composition with intelligent cleaning function, a composite surfactant composition, a facial cleansing product and applications. Background Art

[0002] At present, the surfactants in facial cleansing products mainly include soap-based surfactants, amino acid surfactants, phosphate surfactants, sulfate surfactants, etc. Sulfate surfactants may have dioxin residues due to the presence of ethylene oxide, which poses a risk in terms of safety. Secondly, in terms of application performance, the residual feeling is strong, and users will feel that the face is not clean. Phosphate surfactants may have the risk of polluting rivers and other water bodies due to the phosphorus they contain. Soap-based surfactants have a high pH value, and when used in facial cleansing products, there are problems such as a more obvious tight feeling after washing and not resistant to hard water. Amino acid-based surfactants have a lower pH value, better cleansing feeling, flushing feeling, and are more gentle than soap-based surfactants. However, the current use of amino acid surfactants in facial cleansing products has problems such as dryness, tightness, and irritation on the face after washing, and the mildness cannot meet the needs of users.

[0170] Performance Testing

[0171] 1. Foaming performance in deionized water

[0172] The surfactant compositions of Examples 1 to 10 and the composite surfactant compositions of Examples 11 to 19 were prepared into sample solutions with a concentration of 0.5 wt % using deionized water, heated to 40 (±0.5)°C, and tested for foam performance using a Roche foam meter, and the initial foam height was recorded. The results are shown in Table 4.

[0173] Table 4

[0174]

[0175] The surfactants of Comparative Examples 1 to 8, 13 and 14 were prepared into sample solutions with a concentration of 2 wt % using deionized water, and the foam height was tested using the same test method as above. The results are shown in Table 5.

[0176] Table 5

[0177]

[0178] From the results shown in Table 4 and Table 5, it can be seen that the surfactant compositions provided by Examples 1 to 19 have good foaming ability in deionized water solution. Comparative Examples 1, 2, and 3 have good foaming power in deionized water, while Comparative Examples 4, 5, 6, 8, 13, and 14 have poor foaming power compared to the comparative examples.

[0179] 2. Foaming performance in hard water

[0180] The surfactant compositions of Examples 1 to 10 and the composite surfactant compositions of Examples 11 to 19 were prepared into sample solutions with a concentration of 0.5% using 150 ppm hard water, heated to 40 (±0.5)°C, and tested for foam performance using a Roche foam meter, recording the initial foam height. The results are shown in Table 6.

[0181] Table 6

[0182]

[0183] The foaming heights of the surfactants of Comparative Examples 1 to 8, 13 and 14 in hard water were tested using the same method as above. The results are shown in Table 7.

[0184] Table 7

[0185]

[0186] It can be seen from Table 6 and Table 7 that the surfactant compositions of Examples 1 to 19 have good foaming ability in hard water solution, and even have slightly higher foam height than that in deionized water solution, indicating that they have good hard water resistance.

[0187] Comparative Examples 1, 5 and 6 have good foaming ability in hard water and good hard water resistance. The foaming ability of the remaining comparative examples in hard water is poor compared with the examples.

[0188] 3. Detection of residual amount of monomeric amino acids

[0189] According to the conventional acid hydrolysis method of GB 5009.124-2016, the concentration of residual monomer amino acids in the surfactant solution was detected. The residual monomer amino acids are beneficial to nourishing the skin and have a moisturizing effect. The test results are shown in Table 8.

[0190] Table 8

[0191]

[0192] From the results shown in Table 8, it can be seen that by detecting the free amino acid monomers in the ionic composition solution, it was found that the solution contained a certain concentration of free amino acids.

[0193] 4. Selective cleaning test

[0194] The sample of the embodiment was prepared into a sample with a concentration of 5%, and a sebum formula solution of cholesterol and squalene was smeared on the in vitro pig skin to be tested, and it was left to stand for a period of time to dry, and then the pig skin was stirred and cleaned at a stirring speed of 150r for 30 minutes. After stopping the stirring, the remaining cholesterol and squalene on the pig skin were extracted, and the content of cholesterol and squalene in the solution was determined by liquid chromatography. The washed cholesterol or squalene was divided by the content before washing, which was the cleaning rate. The test results are shown in Tables 9 and 10.

[0195] Table 9

[0196]

[0197] Table 10

[0198]

[0199] As can be seen from the results of Tables 9 and 10, it is found through the selective cleaning test that the above embodiments have good cleaning power for squalene, and at the same time, the cleaning rate for cholesterol is low, which can better maintain the retention of cholesterol on the skin. Comparative Examples 9, 11, and 13 have a high cleaning rate for squalene, and at the same time, the cleaning rate for cholesterol is also high. Comparative Examples 10, 12, and 14 have a high cleaning rate for cholesterol, but the cleaning rate for squalene is relatively low. In the experiment, the inventor hopes to wash away more squalene to prevent oxidation and cause skin inflammation, and hopes to protect cholesterol, a substance that is beneficial to the skin. Therefore, the embodiment is better than the comparative example in retaining cholesterol and removing squalene.

[0200] 5. Moisture test

[0201] The examples and comparative examples were made into samples with an effective concentration of 1wt%, and then quickly foamed with a foamer until the foam was dense and thick. Scoop out enough foam and apply it to the test area, gently circle for 30s, and use a rubber-tipped dropper to absorb deionized water in the control area and apply it in circles for 30s. Then rinse with clean water for 30s, and then gently wipe the moisture on the skin surface with a lint-free paper towel. Test the skin moisture 5 minutes after washing. Use the skin testing instrument Croneometer CM825 and the moisture probe for testing, the skin moisture change rate = (skin moisture after washing-skin moisture before washing) / skin moisture before washing. The results are shown in Table 11.

[0202] Table 11

[0203]

[0204] From the results shown in Table 11, it can be seen that within 5 minutes after the above embodiment is used on the skin, the skin moisture increases significantly, that is, it has a better instant moisturizing effect.

[0205] Example 21, Example 23, Comparative Example 15, and Comparative Example 16 were prepared into 15% concentration aqueous solutions, and then quickly foamed with a bubbler until the foam was dense and thick. The tester wore latex gloves to scoop a sufficient amount of foam and apply it to the test area, gently circling for 30 seconds. The test area was rinsed with clean water for 30 seconds, and then the tester gently wiped the moisture on the skin surface with a lint-free paper towel. The skin moisture content was tested at the set time point. The skin testing instrument Croneometer CM825 was used for testing with a moisture probe. The skin moisture change rate = (skin moisture after washing - skin moisture before washing) / skin moisture before washing. The skin moisture change rate results are shown in Table 12.

[0206] Table 12

[0207]

[0208] From the results shown in Table 12, it can be seen that within 30 minutes after washing, the change rate of skin moisture in Examples 21 and 23 is smaller than that in Comparative Examples 15 and 16. The moisture change rate values ​​of Comparative Examples 15 and 16 are lower, indicating that the amount of moisture lost is greater than before washing, that is, it is drier after washing.

[0209] 6. Antibacterial effect test

[0210] The antibacterial effects of the surfactant compositions of Examples 5 and 9 on Staphylococcus aureus and Propionibacterium acnes were tested in the following manner:

[0211] (1) Recovery and subculture of bacterial strains: Use an inoculation loop to perform inoculation and subculture under sterile conditions. The third generation strains are used as test bacteria.

[0212] (2) Preparation of bacterial solution: Use an inoculation loop to scrape an appropriate amount of the working bacterial strain and inoculate it into the culture medium. After culturing at 37°C for 48-72 hours, dilute the original bacterial solution appropriately with sterile saline to a bacterial count of 1×10 8 cfu / mL~5×10 8 cfu / mL is the working bacterial solution.

[0213] (3) Preparation of sample culture medium: Place the Oxford cup directly on the culture dish with sterile operation, heat the sterilized culture medium until it is completely melted, cool the melted 200mL culture medium to about 50℃, mix it with 4mL of test bacterial solution, and slowly pour it along the wall of the culture dish to evenly distribute the culture medium on the culture dish, and place it on a horizontal surface to solidify. After the plate solidifies, gently press it with sterile tweezers and take out the Oxford cup.

[0214] (4) Sample addition: Add 0.2 mL of the sample solution to be tested into each well in sequence.

[0215] (5) Incubation and observation: Place the plate in a 37±1℃ incubator for 48-72h, observe whether an antibacterial ring is formed in the plate, and use a vernier caliper to measure and record the size of the antibacterial ring.

[0216] The antibacterial test results of the surfactant composition of Example 5 are shown in Table 13. The antibacterial test results of the surfactant composition of Example 9 are shown in Table 14.

[0217] Table 13

[0218]

[0219] Note: “-” indicates no inhibition zone is formed: the inhibition zone diameter in the table has been subtracted from the Oxford ring diameter.

[0220] From the results shown in Table 13, under the conditions of this experiment, the results show that Example 5 has an antibacterial ring formed on Staphylococcus aureus at a concentration of 100%, 50%, and 25%, and the diameter of the antibacterial ring is greater than 10mm, and sterile ultrapure water has no antibacterial ring formed on Staphylococcus aureus. This shows that Example 5 has an antibacterial effect on Staphylococcus aureus at a concentration of 100%, 50%, and 25%. Under the conditions of this experiment, the results show that Example 5 has an antibacterial ring formed on Propionibacterium acnes at a concentration of 100%, 50%, and 25%, and the diameter of the antibacterial ring is greater than 10mm, and sterile ultrapure water has no antibacterial ring formed on Propionibacterium acnes. This shows that Example 5 has an antibacterial effect on Propionibacterium acnes at a concentration of 100%, 50%, and 25%.

[0221] Table 14

[0222]

[0223] Note: “-” indicates no inhibition zone is formed: the inhibition zone diameter in the table has been subtracted from the Oxford ring diameter.

[0224] From the results shown in Table 14, under the conditions of this test, the results show that Example 9 has an antibacterial ring formed on Staphylococcus aureus at a concentration of 100%, and the diameter of the antibacterial ring is greater than 10mm. Example 9 has an antibacterial ring formed on Staphylococcus aureus at a concentration of 50% and 25%, and the diameter of the antibacterial ring is less than 10mm. Sterile ultrapure water has no antibacterial ring formation on Staphylococcus aureus. This shows that Example 9 has an antibacterial effect on Staphylococcus aureus at a concentration of 100%. Under the conditions of this test, the results show that Example 9 has an antibacterial ring formed on Propionibacterium acnes at a concentration of 100% and 50%, and the diameter of the antibacterial ring is greater than 10mm. Example 9 has an antibacterial ring formed on Propionibacterium acnes at a concentration of 25%, and the diameter of the antibacterial ring is less than 10mm. Sterile ultrapure water has no antibacterial ring formation on Propionibacterium acnes. This shows that Example 9 has an antibacterial effect on Propionibacterium acnes when tested at concentrations of 100% and 50%.

[0225] 7. Cleanser Trial Evaluation

[0226] The facial cleansers of Examples 20 to 28 were distributed to ordinary consumers for blind testing, and the test results were evaluated after three trials. Scoring method: Evaluation was conducted based on four aspects: foam richness, flushability, moisturizing after washing, and mildness.

[0227] Foam richness: If the foam is rich, foam will form after 1-2 rounds of rubbing, and the foam will remain stable for 1-2 minutes after rubbing, it can be evaluated as very satisfactory with 5 points. The foam is relatively rich, foam will form after rubbing 3 rounds or more, and the foam stability can last for 1-2 minutes, which can be evaluated as relatively satisfactory. The foam richness is average, foam will form after rubbing 4-5 rounds, and the foam will become slightly less as the number of rubbing increases, and it will remain stable for less than 1 minute, which is evaluated as average. The amount of foam is small, foam will form after rubbing more than 4-5 rounds, and the amount of foam will become significantly less and sparser as the number of rubbing increases, which is judged as unsatisfactory. The amount of foam is very small, and the foam is very small, loose, and unstable after rubbing 4-5 rounds, which can be judged as very unsatisfactory.

[0228] Ease of flushing: If it can be flushed clean with 1-3 times of water, it is very easy to flush; if it can be flushed clean with 1-3 times of water, it is very satisfactory; if it can be flushed clean with 3-5 times, it is relatively satisfactory; if it can be flushed clean with 6-7 times, it is average; if it can be flushed clean with more than 7-8 times, it is not very satisfactory; if it can be flushed clean with 9-10 times, it is very unsatisfactory.

[0229] Moisturizing after washing: If the skin is moisturized within 10 minutes after washing and not dry, it is very satisfactory; if the skin is moisturized within 5 minutes after washing and not dry, it is relatively satisfactory; if there is no moisturizing feeling after washing and the skin feels dry and tight after 5 minutes, it is fair. If the skin is slightly dry and flaky and tight within 5 minutes after washing, it is not very satisfactory. If the skin is obviously dry and tight within 5 minutes after washing, it is very unsatisfactory.

[0230] Mildness: During and after the cleaning process, the eyes and skin do not feel irritated, which is very satisfactory. During the cleaning process, there is slight itching and slight pain in the eyes or face, and no irritation is felt after rinsing, which is relatively satisfactory. During the cleaning process, there is slight itching in the eyes or skin, and the slight itching continues after rinsing, which is fair. During or after the cleaning process, there is a more obvious stinging or itching feeling, which is not very satisfactory; during or after the cleaning process, there is very obvious stinging, burning, and irritation on the face, which is very unsatisfactory.

[0231] Very satisfied is 5 points, relatively satisfied is 4 points, average is 3 points, not very satisfied is 2 points, and very dissatisfied is 1 point. Non-integer scores are allowed. The scores are collected and the average is calculated. The results are shown in Table 15.

[0232] Table 15

[0233]

[0234] From the results in Table 15, it can be seen that after using Examples 20 to 28, the average consumer's satisfaction with the product's foam richness, flushability, moisturizing properties after washing, mildness, etc., is above 4 points, that is, they are generally satisfied, indicating that consumers have a good sensory experience in product application.
