Description

Technical Field

[0001] The invention relates to the field of daily chemicals, and in particular to selenium disulfide anti-dandruff and antipruritic shampoo mud and a preparation method thereof. Background Art

[0002] With the increasing life and work pressure of modern people, the deterioration of environmental air quality, emotional tension and anxiety, staying up late, irregular diet and low immunity, or improper perming and dyeing, excessive cleaning of hair and scalp and other bad living habits, have led to changes in the ecological environment of the hair and scalp, and an imbalance in the scalp oil ecological environment, which in turn leads to excessive proliferation of microorganisms such as Malassezia and Propionibacterium acnes on the scalp. These microorganisms not only increase dandruff, but also decompose sebum to produce free fatty acids and other metabolites, causing inflammatory reactions in the scalp, causing scalp itching, sensitivity, oiliness, odor and other problems, further stimulating the imbalance of sebaceous gland secretion, aggravating symptoms such as dandruff and oily scalp, and in severe cases causing seborrheic dermatitis, hair loss and other symptoms, which has caused great distress and trouble to people today.

[0003] In order to solve the above-mentioned problems such as dandruff, oily scalp, sensitive scalp, dry and coarse hair, there are many shampoo and cleansing products on the market. Although such products can instantly remove dandruff, oily scalp and other problems, due to the use of sulfate cleansers, there are problems such as excessive cleaning and poor mildness, which lead to rapid oiliness and sensitivity of the scalp, as well as rough and dry hair. They cannot achieve the effects of oil control, dandruff removal and itching relief, and light and smooth hair. Summary of the invention

[0004] The purpose of the present invention is to solve the problems of the prior art such as difficulty in gentle oil control and scalp sensitivity, and to provide a selenium disulfide anti-dandruff and anti-itching shampoo mud.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with specific embodiments.

[0029] Effect Example 1

[0030] A selenium disulfide anti-dandruff and antipruritic shampoo mud, the formula components are shown in Table 1:

[0031] Table 1

[0032]

[0033]

[0034] The preparation method of the soothing, moisturizing, antibacterial and antipruritic composition of Examples 1-3 and Comparative Examples 1-11 of the present invention comprises the following steps:

[0035] Process Description

[0036] 1. Add water into the emulsifier according to the measurement, then add water-soluble raw materials such as 15, 17, 18, stir and disperse evenly, heat to 82-88℃, then disperse raw material 8 with appropriate amount of glycerin and add to the emulsifier, continue to stir and disperse until completely dissolved;

[0037] 2. After step "1" is completed, add raw materials 1, 2, 3, 4, 5, 6, 9, 10, 11, 14, 15 into the emulsifying pot and keep warm for dissolution at 82-88°C for 30-60 minutes until the raw materials are completely dissolved;

[0038] 3. After step "2" is completed, start cooling;

[0039] 4. According to the process requirements, mix and grind 16% selenium disulfide powder, 20% glycerol, water and mud to a suitable particle size for later use;

[0040] 5. Cool down to below 48°C, add ground selenium disulfide mixture and raw materials 12, 13, 19, 21, 22, 23, 24, 25, 26, 27, and 28, and use raw material 24 to adjust the pH value to the required range; the material can be discharged after passing the test.

[0041] Effect Example 2

[0042] The preparation of selenium disulfide slurry was compared and the results are shown in Table 2:

[0043] Table 2 Selenium disulfide slurry preparation

[0044]

[0045]

[0046] As can be seen from Table 2, the mixed slurry of Example 4 is evenly dispersed and has good effects during use. Compared with Example 4, the only difference between Example 5 and Example 4 is that glycerol is not added during the grinding process, and as a result, agglomeration occurs after grinding, which shows that glycerol plays a key role in selenium disulfide mud products.

[0047] Effect Example 3

[0048] The selenium disulfide slurry grinding process was compared and tested, and the results are shown in Table 3 and Figures 1 to 5 As shown:

[0049] Table 3 Selenium disulfide slurry grinding process

[0050]

[0051] Optimum particle size of selenium disulfide slurry

[0052] Experimental principle: Selenium disulfide powder is ground into a slurry to obtain different particle size ranges (see Table 3); then selenium disulfide slurries of different particle sizes are applied to the formula, and consumer research tests are conducted to obtain the optimal particle size, as shown in Table 4:

[0053] Table 4 Selenium disulfide slurry particle size selection test

[0054]

[0055]

[0056] Experimental principle: By adjusting the grinding time and rotation speed, different particle sizes of selenium disulfide are obtained (see Table 3.1.2 for particle size), and the anti-dandruff effect is tested through consumer research (selenium disulfide is added in an amount of 0.5%, 35 people with dandruff are selected, each sample is used 3 times, and the effect is tested), and the optimal particle size is obtained. The results are shown in Table 5:

[0057] Table 5

[0058]

[0059] Effect Example 4

[0060] Color change stability

[0061] High temperature stability test, the preferred stabilizer ratio is shown in Table 6:

[0062] Table 6 High temperature test component scheme

[0063]

[0064]

[0065] High temperature stability test

[0066] Experimental principle: Optimize the formula chelating system and determine the best anti-discoloration system; use constant temperature (48℃) and 42 days of testing to observe the color change through high temperature testing. The darker the color change, the worse the paste stability, the more obvious the redox reaction, and the more unstable it is at high temperature, as shown in Table 7.1. The comparative scheme is shown in Table 7.2.

[0067] Table 7.1

[0068]

[0069] Table 7.2

[0070]

[0071] As can be seen from Table 7, from the comparison of experimental phenomena, Example 3 and Example 4 are within the acceptable range, indicating that the anti-discoloration effect of the formula is ideal and the chelating system is stable.

[0072] Effect Example 5

[0073] Comparison test

[0074] The embodiments are all carried out with the following formulation combinations, see Table 8:

[0075] Table 8

[0076]

[0077]

[0078] Anti-dandruff ability test

[0079] Test principle: The antibacterial circle test method is used to determine the antibacterial efficacy by comparing the size of the antibacterial circle. This experiment uses Malassezia as the experimental strain, and the experimental method refers to the Oxford cup method for antibacterial testing; the antibacterial circle diameter <7mm has no antibacterial effect, and the antibacterial circle diameter >7mm has an antibacterial effect. The larger the value, the better the antibacterial effect, indicating that the antidandruff effect is stronger. The results are shown in Table 9.1. The comparative scheme is shown in Table 9.2.

[0080] Table 9.1

[0081]

[0082]

[0083] Table 9.2

[0084]

[0085] It can be seen from Table 9 that the antidandruff abilities of Examples 4 to 6 are better than those of the comparative example, and all have good antibacterial effects.

[0086] Component Mildness Assessment

[0087] Principle of mildness test: Zein nitrogen determination method is used to determine irritation. Zein is insoluble in water, but it dissolves in water after denaturation. Zein is added to an aqueous solution containing a surfactant. Since Zein has a high nitrogen content, the nitrogen content in the solution increases. The difference in nitrogen content in the system before and after Zein dissolution (i.e., Zein value) is used to characterize the solubility of Zein in the system, and then the irritation of the system. The larger the Zein value, the more Zein is dissolved, and the more irritating the surfactant system is. Zein values ​​> 4gN / L are strong irritants, Zein values ​​2 to 4gN / L are low irritants, and Zein values ​​< 2gN / L are non-irritants. The lower the Zein value, the lower the irritation. The results are shown in Table 10:

[0088] Table 10

[0089] Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Zein value (gN / L) 3.21 3.42 3.36 3.23 3.45 3.57 Irritation level Low stimulation Low stimulation Low stimulation Low stimulation Low stimulation Low stimulation Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Comparative Example 6 Zein value (gN / L) 3.81 4.11 3.92 3.76 3.86 4.23 Irritation level Low stimulation Strong stimulation Low stimulation Low stimulation Low stimulation Strong stimulation

[0090] Note: The comparative example is consistent with that described in Table 9.2.

[0091] It can be seen from Table 10 that Example 1 and Example 4 are both superior to the comparative example in terms of mildness, and the mildness is relatively good.

[0092] Combability test evaluation

[0093] Combing test principle: Use a combing instrument to test the combing work, compare it with the benchmark, and calculate the improvement rate. The higher the data, the better the improvement effect. The results are shown in Table 11:

[0094] Table 11

[0095] project Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Wet combing improvement rate (%) 38.3 34.2 39.6 42.2 38.5 40.8 Dry combing improvement rate (%) 35.2 29.6 35.3 36.9 35.5 35.7 project Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Comparative Example 6 Wet combing improvement rate (%) 31.3 33.6 35.8 34.8 32.9 36.4 Dry combing improvement rate (%) 28.9 29.8 31.2 34.2 31.1 33.7

[0096] Note: The comparative example is consistent with that described in Table 9.2.

[0097] As can be seen from Table 11, the examples are generally better than the comparative examples in improving wet and dry combing, among which Example 4 performs best.

[0098] Dry hair volume test

[0099] Test principle: By comparing the volume of dry hair, the dry hair volume of the test component is compared (compared with the reference standard hair). The results are shown in Table 12:

[0100] Table 12

[0101]

[0102] Note: The comparative example is consistent with that described in Table 9.2.

[0103] It can be seen from Table 12 that Example 4 has the best and better fluffy effect, which is better than other examples and comparative examples.

[0104] Customer satisfaction test

[0105] Consumer satisfaction test: 35 volunteers with dandruff were selected to evaluate the effect of use, and the ratio of the number of recognized people to the total number of people was used for statistics. The higher the number, the higher the recognition. The results are shown in Table 13:
