Description

Technical Field

[0001] The present invention relates to the technical field of daily chemical products, and in particular to a hair care product and application thereof. Background Art

[0002] In real life, urban environmental pollution, ultraviolet radiation, hair perming and dyeing, combing and hot drying can cause different degrees of damage to hair, making hair frizzy and difficult to comb, dry and dull, split and easy to break. At present, shampoo contains cationic polymer conditioning agents such as polyquaternium-10 and guar hydroxypropyltrimonium chloride, as well as oils such as silicone oil and vegetable oil. Oils such as silicone oil and vegetable oil have a hydrophobic effect, which can improve the hydrophilicity of hair and the frizz problem. Cationic polymer conditioning agents can help oils deposit on the hair, increase the utilization rate of oils and improve combing performance.

[0003] However, while existing shampoos improve the problem of frizziness, they also cause itching, and with the accumulation of grease and cationic polymer conditioning dosage, the hair will gradually become flat and greasy. For example, patent CN114432183A uses polyquaternium-47, polyquaternium-4, and palmitamidopropyl trimethyl ammonium chloride to achieve fluffy hair, but the small molecule cationic surfactant palmitamidopropyl trimethyl ammonium chloride is prone to itching and irritation. Therefore, it is necessary to develop a shampoo and care product that can repair damaged hair well, reduce frizziness, and improve hair smoothness, while not causing excessive deposition of greasy and heavy feelings, and will not irritate the scalp.

[0064] Performance tests were performed on Examples 1 to 6 and Comparative Examples 1 to 7:

[0065] 1. Fluffiness test:

[0066] In order to reduce the interference of hair blowing, combing and living habits with the fluffiness test results, the fluffiness test is performed on a hair bundle in this embodiment. The specific steps of the fluffiness test method include:

[0067] 1. Pre-cleaning: Wash the hair with 5% SLES solution once, and hang it in a constant temperature and humidity environment to dry overnight for later use;

[0068] 2. Pre-treat the hair with 1% artificial sebum ethanol solution, dry it, then wash the hair with the shampoo sample, and let it dry naturally for later use;

[0069] 3. Wash the hair strands with the shampoo to be tested, using 0.6 ml per strand, rubbing for 30 seconds, and rinsing for 30 seconds;

[0070] 4. Hang the washed hair bundle in a constant temperature and humidity room (Rh55%, 22°C) to dry overnight;

[0071] 5. Keep the hair dry and do not comb it. Figure 1 Take photos of the hair bundles under this condition (4 photos per bundle);

[0072] 6. Import the photos into Image Pro image analysis software and calculate the fluffiness of each strand of hair. The fluffiness test results are shown in Table 3.

[0073] Table 3 Fluffiness results of the application example after one wash and three washes

[0074]

[0075]

[0076] The data in Table 3 can be sorted into Figure 2 The data comparison chart shown is from Figure 2 It can be seen that there is a significant difference in the results of the one-washing fluffiness of Examples 1 to 6 and Comparative Examples 1 to 7, and there is also a significant difference in the results of the three-washing fluffiness of Examples and Comparative Examples 1 to 7. At the same time, it can be found that after washing three times, the fluffiness of the hair of Comparative Examples 1 to 7 is lower than that of washing once, while the fluffiness of Examples 1 to 6 after washing three times is improved compared with washing once.

[0077] 2. Combing test:

[0078] The combing test is to test the combing force or combing work of human hair bundles separated from the body by a hair bundle combing instrument, which is used to evaluate the effect of the hair care products on improving the damage of the hair bundles. The specific steps of the combing test method include:

[0079] 1. Hair bundle selection: select hair bundles that have not been tested and perform combing tests on them. Select hair bundles with no significant difference in combing force or combing work for testing of application examples. The hair bundles used for application tests are divided into a control group and a test group, with 3 hair bundles in each group for each application test.

[0080] 2. Hair bundle pretreatment: Wash the hair bundle with clean water at a temperature of 38±1°C. After washing, dry it in a constant temperature and humidity chamber for use. The conditions of the constant temperature and humidity chamber are set at 23±0.5°C and 60±5%RH.

[0081] 3. Baseline wet hair combing test (W0): The test group hair bundles are fully wetted with running constant temperature clean water, and 0.2 grams of cleaning solution is used per gram of hair bundles, and the surface of the hair bundles is evenly applied for about 30 seconds, left to stand for about 1 minute, and then rinsed for about 30 seconds. The treated hair bundles are fixed in the test position for combing cycle test.

[0082] 4. Baseline dry hair combing test (D0): The hair bundle after the wet hair test is placed in a constant temperature and humidity chamber for more than 4 hours, taken out and fixed in the test position, and the combing cycle test is performed. The hair bundle after the test is placed in a constant temperature and humidity chamber for use.

[0083] 5. Sample wet hair combing test (W1): Wet the hair bundle that has completed the baseline combing test with running constant temperature clean water, and evenly apply 0.2 grams of sample per gram of hair bundle or the amount in accordance with the sample usage method on the surface of the hair bundle for about 30 seconds, let it stand for about 1 minute, and then rinse for about 30 seconds or skip rinsing. Fix the treated hair bundle in the test position for the combing cycle test.

[0084] 6. Sample dry hair combing test (D1): After the wet hair test, the hair bundle is placed in a constant temperature and humidity chamber for more than 4 hours, taken out and fixed in the test position for combing cycle test.

[0085] 7. Calculation of combability improvement effect: Wet hair combability improvement = (W0-W1) / W0×100%; Dry hair combability improvement = (D0-D1) / D0×100%.

[0086] Table 4 Combing test results of the application example after one cleaning and three cleanings (unit: mN)

[0087]

[0088] According to Table 4, the combing improvement of the hair bundle after one washing and three washings was calculated, as shown in Table 5.

[0089] Table 5 Combing improvement results of the application example after one cleaning and three cleanings

[0090]

[0091] The significant difference of the data in Table 5 was calculated, and the significant difference of the improvement of wet hair combing property was as follows: Figure 3 As shown, the significant difference in dry hair combing improvement is as follows Figure 4 As shown. Figure 3 and Figure 4 It can be seen that when the hair bundle is washed once, there is no significant difference (ns) in wet hair combing performance and dry hair combing performance between Comparative Examples 1 to 7 and Examples 1 to 6. When the hair bundle is washed three times, there is no significant difference (ns) in wet hair combing performance between Comparative Examples 1 to 7 and Examples 1 to 6, but there is a significant difference (***) in dry hair combing performance.
