[0054] 0.25 parts of PPG-3 octyl ether

[0055] A mixture of water, polyquaternium-7, phenoxyethanol, and ethylhexylglycerin (mass ratio 5:2:2:1), 1 part; PEG-7 glyceryl cocoate, 0.15 parts.

[0056] 0.3 parts trehalose

[0061] Water to a final volume of 100 portions.

[0062] The preparation method of the vitamin anti-dandruff shampoo described in this invention is as follows:

[0063] 1. Add 50% deionized water to a mixing pot, turn on the stirring, and add disodium EDTA, sodium lauryl ether sulfate, and ammonium lauryl sulfate in sequence. Stir and heat to 70°C, and stir until completely dissolved and transparent.

[0064] 2. Add palm kernel oleamide DEA, sodium citrate, capryloyl glycine, and allantoin, and stir until completely dissolved and transparent.

[0065] 3. Using 10% deionized water in a clean container, mix hydroxypropyl guar gum hydroxypropyl trimethyl ammonium chloride and guar gum hydroxypropyl trimethyl ammonium chloride evenly, add to a mixing pot and stir evenly for 5 minutes, then start cooling.

[0066] 4. When the temperature drops to 60℃~55℃, add sodium cocoyl methyl taurate, cocamidopropyl betaine, sodium chloride, sodium benzoate, glyceryl laurate, sodium cocoyl aminopropionate, PPG-3 octyl ether, polyquaternium-7, phenoxyethanol, ethylhexylglycerin, PEG-7 glyceryl cocoate, and trehalose in sequence, and stir well.

[0067] 5. Once the temperature drops below 45℃, add the remaining ingredients (excluding deionized water) to the mixing bowl and stir until well mixed.

[0068] 6. Stop cooling, add the remaining 40% of deionized water, and stir well.

[0069] Panthenol contains ester bonds and hydroxyl groups, making it susceptible to the effects of water. In the presence of water, the ester bonds can be hydrolyzed. Water molecules nucleophilically attack the ester bonds of panthenol, forming intermediates that subsequently release alcohols or acids. Acidity / base value, complexes, solvents, and temperature all affect panthenol. This invention discovered that using copper peptides and betaine during the preparation process can mitigate the hydrolysis of panthenol to some extent; on the one hand, by protonating the nucleophile, its nucleophilicity is reduced, thereby inhibiting the reaction. On the other hand, non-covalent interactions interfere with the nucleophilic reaction, creating steric hindrance to alleviate the reaction.

[0070] On the other hand, the present invention stabilizes the overall stability and efficacy of the composition in the base formula by adding surfactants similar to sodium aspartate into the overall formulation.

[0071] The present invention will be further explained below with reference to specific embodiments.

After 30 days, the samples were brought back to room temperature, and their appearance was observed to determine if there were any changes. A 5℃-45℃ thermal cycling test was conducted for two cycles. The test results are shown in Table 1.

[0152] Table 1 Performance Test Results

[0153]

[0154]

[0155] Test 2: The panthenol content was determined using HPLC, and the content was measured every month for 8 months. The panthenol content obtained from the tests is shown in Table 2 below. The retention rate is obtained by dividing the test results by the initial panthenol results.

[0156] Table 2 Test Results

[0157]

[0158] Test 3: Combing Test: By conducting friction work test and gloss test on hair strands before and after sample treatment, the effect of the test sample on improving the friction work and gloss of hair strands is evaluated, and the repair efficacy of the product is verified.

[0159] friction

[0160] The frictional work done on the hair strands before and after using the sample was measured using a precise force sensor on a combing device. The degree of reduction in frictional work was used to measure the effectiveness of the sample in repairing the hair strands. The less frictional work was done, the smoother the hair strands were.

[0161] Materials: Black, damaged, flat hair strands, 15cm long, 3.0g

[0162] Testing instruments: hair comber, electronic balance.

[0163] Environmental requirements: Temperature: 21.0℃±1.0℃; Humidity: 50%±10%

[0164] Friction test

[0165] 1. Randomly select 5 identical flat hair bundles (3.0g, 15cm, damaged hair bundles) and equilibrate them in a constant temperature and humidity environment [(21±1)℃, (50±10)%RH] for 24 hours;

[0166] 2. Use a hair combing device to test the friction work done by 5 hair strands, once for each strand, and record the friction work value (before treatment);

[0167] 3. After washing the hair bundles, wipe off excess water. Take a sample of 0.1g / g of hair from each bundle and apply it to the hair strands. Leave the sample on for 1 minute, then rinse with running water for 30 seconds. Repeat this process once. Place the detached hair in a constant temperature and humidity environment [(21±1)℃, (50±10)%RH] to air dry naturally for 24 hours.

[0168] 4.24 hours later, the friction work done by the hair strand was measured again using a hair strand combing instrument (after processing).

[0169] Use Excel to perform descriptive statistics on data, including mean and standard deviation.

[0170] Use SPSS software to test the significance of the normal distribution of the data. If the sample group data Sig. (two-tailed) > 0.05, then it is normally distributed, and a paired-samples t-test is performed with a significance level of α = 0.05; otherwise, a rank-sum test is performed.

[0171] The test results are shown in Table 3.

[0172] Table 3 shows the test results of performance test 3.

[0173]

[0174]

[0175] Test 4: Dandruff Removal Performance Test

[0176] The products prepared in Examples 1 to 8 were subjected to a dandruff questionnaire test. Forty subjects were selected, aged between 20 and 45 years, including 10 males and 30 females.

[0177] The questionnaire content is shown in Table 4.

[0178] Table 4. Questionnaire content of participants in the dandruff treatment program.

[0179]

[0180] A score of 5 indicates complete agreement, 4 indicates moderate agreement, 3 indicates both agreement and disagreement (neutral), 2 indicates moderate disagreement, and 1 indicates complete disagreement. The result is a composite score of the 40 rankings.
