[0114] Test Example 2: Wet and dry combing performance test

[0115] Test samples: samples provided in Examples 1-9 and Comparative Examples 1-9, and commercially available shampoo samples;

[0116] (1) Pretreatment and simulated use: 19 groups of hair bundles were cleaned with 1% NaOH aqueous solution. The specific steps are as follows:

[0117] a) Soak the hair tress in a 1% NaOH aqueous solution for 5 minutes;

[0118] b) Rinse the hair with clean water for 2 minutes;

[0119] Repeat this process twice to complete the basic washing of the hair bundle, and blow dry the hair bundle with a hair dryer;

[0120] (2) Randomly divide the hair bundles into test groups and perform sample simulation use:

[0121] 1) Rinse the hair with clean water for 1 minute;

[0122] 2) Apply 2g of the test sample to wet hair and massage thoroughly for 1 minute;

[0123] 3) Rinse the hair with clean water for 2 minutes;

[0124] This process is repeated twice to complete the simulated use of the sample;

[0125] (3) Wet combing performance test: The test group with controlled moisture was subjected to wet combing performance test using a Baosheng TA.XTC-20 texture analyzer. The maximum positive force was tested. The smaller the area at the maximum positive force, the better the combing performance of the test hair bundle.

[0126] (4) Dry combing performance test: The test group that has completed the wet combing performance test was blown dry with a hair dryer, and a dry combing performance test was performed using a Baosheng TA.XTC-20 texture analyzer to test the maximum positive force. The smaller the area to the maximum positive force, the better the combing performance of the tested hair bundle.

[0127] The specific test results are shown in Table 4 below:

[0128] Table 4

[0129]

[0130]

[0131] It can be seen from the test results in Table 4 that, compared with the dry and wet combing performance results of commercially available shampoos, the shampoo of the present invention has better dry and wet combing performance.

[0132] It can be seen from Examples 4-6 that the combination of cocamidopropyl hydroxysultaine, coco-glucoside and sodium cocoyl methyl taurate can better improve the wet and dry combing performance of shampoo.

[0133] As can be seen from Examples 7-9, PEG-80 sorbitan laurate, sodium cocoyl isethionate, and polyquaternium-10 have a synergistic effect. Their combined use can better improve the wet and dry combing performance of the shampoo and have a better conditioning effect on the hair.

[0134] It can be seen from Comparative Examples 1-2 that the shampoo of the present invention has a better conditioning effect only when an emollient and a surfactant are used in combination.

[0135] It can be seen from Examples 4-9 that the addition of a skin conditioner, and only when the skin conditioner is a combination of camellia extract, lime peel extract, scutellaria baicalensis flower / leaf / stem extract, glyceryl glucoside and rambutan peel extract, can the dry and wet combing performance of the final shampoo be better.

[0136] Test Example 3: Moisturizing Effect Evaluation

[0137] (1) Tested substances: samples of Examples 1-9 and Comparative Examples 1-9;

[0138] (2) Volunteers: 126 volunteers, aged 18 to 25 years, were randomly divided into 18 groups, with 7 people in each group (3 males and 4 females). Each group of volunteers tried the samples of the experimental group respectively;

[0139] (3) Test site: forearm;

[0140] (4) Usage: Take an appropriate amount of the test substance on your hand, apply it evenly to the designated area of ​​your arm and rub it to form foam. Rinse it with water after cleaning.

[0153] As shown in Table 7, the two-in-one bath and shower product of the present invention has excellent foam volume, foaming speed, rinsing properties, smooth feeling, and moisturizing feel. As shown in Examples 4-6, the absence of any component in the surfactant will lead to a decrease in foam volume and foaming speed, and coco-glucoside will also affect the rinsing property of the product. As shown in Examples 7-9, the absence of PEG-80 sorbitan laurate will reduce the foam volume, smooth feeling, and moisturizing feel of the product. The absence of sodium cocoyl isethionate will also lead to a significant decrease in rinsing properties, and the foam quality, smooth feeling, and moisturizing feel will also decrease to a certain extent. Polyquaternium-10 has a greater impact on the smooth feeling and moisturizing feel of the product.
