Description

Technical Field

[0001] The invention relates to the field of personal washing and care, and relates to a surfactant composition with skin / scalp oil control / dandruff prevention effects. Background Art

[0002] With the in-depth development of the economy and society, all aspects of life have made great progress, and the level of residents' consumption has been greatly improved. Residents' demand for consumption is increasing day by day, and they are no longer just meeting single functional needs, but pursuing more beautiful personal consumer products. The development in recent years has led to the rapid development of related industries such as care and beauty whitening that improve the quality of life.

[0003] In the field of washing and skin care, the feeling of cleanliness and freshness has always been the goal pursued by users. However, researchers have been exploring effective and economical solutions to effectively cleanse the face or scalp tissue, effectively inhibit oil secretion, and control oil for a long time, and inhibit the recurrence and generation of dandruff.

[0004] A large number of documents have been published to study such problems. For example, Chinese patent publication CN103655413A relates to a deep decontamination and oil-control cleanser, which is made of the following raw materials in parts by weight: 5-15 parts of nano bamboo charcoal powder, 3-9 parts of sodium alginate, 4-8 parts of glycerol, 15-25 parts of polyacrylic acid resin, 4-8 parts of triethanolamine, 25-30 parts of silk extract, 5-10 parts of cucumber extract, 3-9 parts of black sesame extract, 4-8 parts of vitamin C, 3-9 parts of peppermint essential oil, 3-6 parts of sodium lauryl sulfate, 2-6 parts of alkyl glycoside, 4-6 parts of jojoba oil, 2-7 parts of squalane, 4-10 parts of glycerol, and 10-20 parts of deionized water. The present invention provides a deep decontamination and oil-control cleanser that can remove dirt deep in the skin, moisturize the bottom layer of the skin, replenish water and lock water to achieve a significant oil control effect. However, the components designed by this type of patented technology are complex, the effective ingredients are unclear, and multiple surfactants are usually used in a balanced combination. This is not conducive to the performance of cleansing and care products that focus on oil control and fat inhibition, nor is it conducive to meeting consumers' needs for economy, efficiency and simplicity.

[0005] Therefore, there is still a need for improvement and development of the existing related technologies. Summary of the invention

[0020] The present invention is described in more detail hereinafter to facilitate understanding of the invention.

[0021] Before describing the specific implementation scheme, it should be noted that those skilled in the art can select appropriate raw materials according to the enlightenment and teaching of this disclosure, and use relevant testing equipment to perform relevant tests and obtain corresponding results. For raw materials without specific manufacturers or routes, those skilled in the art can select raw materials that meet the corresponding requirements as the starting materials of the formula or method according to the disclosure and requirements of this specification. The complex chemical substances of the present invention can be purchased from specific suppliers or synthesized by existing technologies known to those skilled in the art, and these synthesis technologies do not need to be discussed in detail here.

[0022] In order to better show the effect of the surfactant composition with skin oil control effect adopted by the present invention, in most embodiments, a surfactant composition composed of main components is used. However, it is understood that the composition of the present invention can also add a small amount of other auxiliary components as needed, for example, as needed, the composition can add 0.1% to 0.5% of the total weight of the pH regulator (such as citric acid), and can also contain 0.1% to 1% of the total weight of the fragrance, and / or 0.1% to 0.5% of the preservative. However, in preferred and other schemes, the surfactant composition can be composed only of the main components listed in the technical solution protection request or the embodiment, without other components. In particular, the surfactant composition of the present invention may not contain other surfactant components, other 5α-reductase inhibitors, and other anti-dandruff, sterilization or disinfection components. In addition, for the composition of each chemical substance, those skilled in the art are clear about its meaning. For example, for betaine, the experimental example of this experiment is preferably betaine without a derivative group.

[0023] In a typical sebum measurement experiment of the embodiment of the present invention, a sebum meter provided by Courage / Khazaka Electronics Co., Ltd. of Germany was used for measurement (in the measurement of absolute sebum valuation, a sebum meter Sebumeter SM815 can also be used).

[0024] During the sebum suppression test, 20 male volunteers between the ages of 35 and 45 were recruited for the test and the sebum production in their forehead area was analyzed. For each subject, the forehead was thoroughly washed with soap and cleaned twice with 70% disinfectant alcohol. After 15 to 30 minutes, the sebum production was measured with a sebum meter. In each measurement, the sebum meter tape probe (7mm×7mm) covered 49mm 2 The area around the forehead. The 3cm square area (about 9cm 2 ) and perform ten measurements within .

[0025] The sebum meter detects the difference in transparency before and after the patch is placed on the forehead for 30 seconds and expresses the difference as an arbitrary number (S value) between 0 and 300. The S value of sebum accumulated on the forehead of men is usually 100 to 300. The skin surface on the hands usually shows very low values ​​(5 to 20). The S value of the forehead immediately after washing is less than 5. The S value gradually increases to about 30 to 40 within 30 minutes after washing, and usually reaches 100 to 200 or even higher within a day or a few days.

[0026] To determine the rate of sebum production, the corresponding areas of the left and right forehead regions are measured alternately. Ten measurements on each side take about 15-20 minutes and the sebum S value is about 30 to 200. The S values ​​of different areas of the forehead vary greatly and may also be affected by the environment, including the season of the test, the diet and physical health of the subject, etc. However, when no composition is applied after cleaning, the ratio of the total S value of the left forehead (the total of 10 measurements) to the total S value of the corresponding position on the right side is usually basically constant. In the experiment, the inventor found that if the S value is measured 15 to 20 minutes after thoroughly cleaning the forehead, the left / right ratio is within 0.95 to 1.15. Thus, in a natural state, if the corresponding composition or medicine to be tested is applied only to the left forehead of the subject, and the left / right ratio can be reduced to below 0.95 or even below 0.9 thereafter, it can be considered that there is a corresponding inhibitory effect on forehead sebum. In this experiment, after the above cleaning process, the test substance (about 2 ml) is applied to the left forehead of the test subject (the right side is cleaned with disinfectant alcohol), and it is applied twice with an interval of 15 minutes on each day of the test; it is applied for three consecutive days. Stop using the composition after 3 days of application, and then wait for different time periods for retesting, and wait for up to 14 days to observe the change in the left / right ratio to reflect the change in the ratio (during this period, the test subject is in normal activities, but does not use any cleaning composition to clean the test area); or, after the cleaning process, apply different test substances to the left and right foreheads respectively (for example, the composition of the embodiment is applied to the left forehead, and the test substance of the comparative example or other embodiments is applied to the right forehead), and observe the inhibitory effect of different substances on sebum. In the following tests, the measured ratio value is referred to as "S / ".

[0027] In terms of the comfort of the product to be used, the inventors also conducted an in vitro skin irritation test, which was based on the application of EpiSkin TM Model, which can be used for in vitro skin irritation (standard model of OECD TG439 and Chinese industry standard SN / T4577-2016).

[0028] In a typical test procedure, the culture plate containing the skin tissue is placed in an incubator at (36±1)°C, (8±1)% CO2, and 90% relative humidity for 24 hours. Five tissues are used for each sample in parallel. Each tissue is given 20μL of sample solution, 20μL of PBS (phosphate buffered saline), and then 10μL of 5% SLS aqueous solution (sodium dodecyl sulfate aqueous solution) is added. After exposure to room temperature for 20 minutes, 25mL of PBS is aspirated to rinse the tissue. The culture plate is continued to be incubated in the incubator for 48 hours. Take 0.3mg·mL -1MTT solution, put the model into a 12-well plate, add 2mL MTT solution to each well, and culture in an incubator for 5h. After the culture is completed, the epidermal tissue sample is removed with a puncher, transferred to a centrifugal microtube, 1mL acidic isopropanol is added, shaken and mixed, and placed at room temperature and away from light. For each tissue, 2 500μL solutions are pipetted into the well plate in parallel, acidic isopropanol is used as a blank control, and the optical density value is read at a wavelength of 570nm to analyze the MTT test results. After analyzing the survival rate of the epidermal tissue, it is classified: if the survival rate of the epidermal tissue is less than or equal to 30% of the control group, it is scored as 1 (strong irritation); if the survival rate of the epidermal tissue is between 30% and 50%, it is scored as 2 (moderate irritation); if the survival rate of the epidermal tissue is greater than 50% and less than 75%, it is scored as 3 (weak irritation); if the survival rate of the epidermal tissue is greater than or equal to 75%, it is scored as 4 (non-irritating). If the test requires, the average value of the results of 5 parallel tests can be obtained by rounding off to one decimal place to obtain the numerical value of the test result (J).

[0029] Regarding the improvement of dandruff and / or scalp oiliness, the testers themselves evaluated on a 5-point scale, with 1 point indicating that the dandruff situation is still deteriorating or has not improved, 5 points indicating the most obvious improvement, 3 to 4 points indicating slight improvement, and 2 points indicating that it is difficult to tell whether it has improved. If necessary, the average of the scores of the 20 testers can be taken, and the value of the test result (X) can be obtained by rounding to 1 decimal place.

[0030] In the main aspect of product usage experience, 1 point is the worst and 5 points are the highest. The subjective evaluation is mainly based on the feel of the composition when applied, the subjective feeling after contact with the scalp or skin, and the moisturizing, cleansing, greasy and smooth feeling after use (U).

[0031] In a typical hair cleaning procedure, the tester cleans the hair once with a common shampoo (non-oil control and anti-dandruff series) before the test. Then, after one day, the tester cleans the hair with the composition of the inventive experimental example or the comparative example, once a day, for a total of two times. Then, after 7 days, fill in the survey intention to indicate the improvement of dandruff and scalp oiliness of the composition.

[0032] The main raw materials used in the present invention and the corresponding acquisition channels or raw material origins are listed in Table 1. It should be noted that the raw materials not described in the present invention are raw material varieties that can be obtained by those skilled in the art based on common technical knowledge and existing market products.

[0034]

[0035]

[0036] Experimental Example 1

[0037] The surfactant composition with oil control effect according to each embodiment of the present invention is composed of sodium cocoamidopropionate, adenosine, betaine and an appropriate amount of purified water (the following proportions are all weight percentages).

[0038] Table 2: Surfactant composition of the oil control effect of the embodiment

[0039]

[0040] In the above experimental examples of the present invention, only four components A, B, C, and D are used as components of the composition. However, it is clear to those skilled in the art that other auxiliary components can also be added to this experimental example to form a shampoo, facial cleanser or shower gel that is more suitable for consumer use or commercial use, such as adding a small amount (0.5% to 2% by weight of the total weight of the composition) of fragrance, pH regulator, viscosity regulator, etc. However, the above auxiliary components have no substantial contribution to the actual effects of effective oil control, fat suppression, and or inhibition of dandruff regeneration. The above composition can control oil for sebum, and can also be used as a shampoo component to control oil and dandruff on the scalp.

[0041] The inventors first characterized and measured the sebum measurement (S / , where S / 1 represents 1 day, S / 7 represents the result after 7 days, and S / 14 represents the result after 14 days), epidermal tissue irritation (J), and the improvement of dandruff / scalp sebum after shampooing (X), as well as the subjective feeling (U) for the above experimental examples:

[0042] Table 3: Test results of oil control and fat suppression of experimental composition

[0043] Experimental example S / 1 S / 7 S / 14 J X U E1 1.05 0.25 0.36 3.3 4.6 4.0 E2 1.03 0.30 0.42 3.5 4.2 4.5 E3 0.99 0.35 0.40 3.0 4.0 4.3 E4 1.01 0.62 0.68 3.7 3.6 3.3 E5 0.95 0.22 0.40 2.8 4.5 4.2 E6 1.02 0.39 0.55 3.2 3.8 3.5

[0044] As can be seen from the above experimental examples, the experimental examples of the present invention E1 to E3 have achieved good feedback and data test results in terms of oil control and fat suppression, skin tissue irritation, scalp oil improvement and subjective feelings of the subjects. In the test results, when S / 1 just passed the left and right forehead skin cleaning test, the oil secretion and distribution effects of the left and right foreheads were not much different, so when measured on 1 day, the ratio of the left / right forehead skin was close to the normal ratio. However, as time goes by, the oil control effect of the experimental example composition of the present invention is significantly reflected. When it lasts for about 7 days, since the right forehead part has not been cleaned by the composition of this experimental example, the amount of oil secretion increases rapidly, and the oil secretion of the skin part on the left side that is cleaned by the corresponding composition slows down, resulting in the left / right ratio "S / 7" being significantly lower than the original measured equilibrium value (such as 0.95 to 1.05); when it lasts for 14 days, the speed difference of the left and right oil secretion slows down, so the measured value rises accordingly. The inventors also estimated the absolute oil content of E1 and E2 and found that the absolute sebum content of the two experimental examples measured at 7 days was 125 μg / cm 2 and 140 μg / cm 2 , which is more than 50% lower than the oil content of the ordinary cleaning process and the non-oil control component cleaning process. The above experiments and tests show that the composition can achieve good results under the combination of specific surfactants and ratios and specific adenosine. Of course, it is also not subject to any theoretical constraints, but the inventors believe that this is related to the effective inhibition of the production of 5α-reductase on the skin surface.

[0045] On the other hand, when the content of sodium cocoylaminopropionate as one of the components of the surfactant is too high (E5), the inventors found that although the oil control effect can be guaranteed over time, the skin irritation test is significantly deteriorated (J), which makes the proportion of component A of the present invention preferably not more than 40%, and most preferably not more than 32% by weight; and when the proportion of component A is too low (E4), the test results for S / 7 and S / 14 are deteriorated, indicating that the ability of continuous oil control, moisturizing and secretion inhibition is insufficient. Therefore, in this embodiment, the proportion of component A is preferably greater than 20% by weight, and most preferably greater than 25% by weight. The inventors also unexpectedly found that when oleamidopropyl betaine or cocoamidopropyl betaine is used to replace betaine (E6), on the one hand, the subjective feeling of the user is deteriorated, and on the other hand, the test results of S / 7 and S / 14 are reduced compared with E1, so this experimental example can use derivatives of betaine at all levels, but preferably, betaine itself is used in combination with components A and B. The embodiment of the present invention can also use neoacylglycine to replace betaine, but the moisturizing and other auxiliary and superimposed combination functions of neoacylglycine are not as good as those of betaine.

[0046] The inventor does not want to be bound by any theory, but after research, it is believed that it may be related to the carbon chain length of the derivatives of betaine at all levels, which may be associated with the effect of inhibiting 5α-reductase. On the one hand, oleic acid amidopropyl betaine or cocoamidopropyl betaine with a high carbon chain length has a longer carbon chain, which increases the oily feel and reduces the refreshing skin touch of the user. In addition, when adenosine as a saponin component and sodium cocoamidopropionate with a longer carbon chain are used as the main components for controlling oil and inhibiting oil, short-chain betaine molecules can be easily inserted into long-chain sodium cocoamidopropionate and adenosine molecules, so that long-chain molecules are more evenly distributed on the skin surface without aggregation, and better control oil and fat for a long time on the entire application area, while inhibiting the production of reductase. At the same time, betaine can also play a certain moisturizing effect and increase the texture of use. However, small molecule betaine has a certain sensory irritation, and the amount used cannot be too large. In the experimental example of the present invention, the betaine content is preferably not more than 5% by mass, and optimally not more than 3.5% by mass.

[0047] The inventors also took further photos to characterize the shampooing effect of Experimental Example E1, see Figure 1 and Figure 2 .in Figure 1 This is a photo of the scalp taken 7 days after the composition of Experimental Example 1 of the present invention was used for corresponding cleaning (taken using a Nikon D850 SLR camera equipped with a Nikkor Z17-28mm f / 2.8 lens). Figure 1 It can be seen that 7 days after cleaning, the scalp is covered with a small amount of oil, the hair roots are clear and the amount of scalp oil is controllable. Figure 2 The photo of the hair roots taken with the same device after washing with ordinary shampoo for 7 days shows that the hair roots are blurred and the thickness of the oil layer increases significantly and covers the hair roots. Therefore, the composition of the present invention not only has a good oil control effect on the face, forehead or body skin, but also has a good inhibitory effect on scalp oil and even dandruff.

[0048] Comparative Example 1

[0049] In this series of experiments, the corresponding components were replaced and the performance of the composition was evaluated again. Basically, the content of each component in the control example was implemented according to E1 in the control experiment example. The values ​​in the control example were still calculated as weight percentage in the total composition.

[0050] Table 4: Test results of oil control and fat suppression of control composition

[0051]

[0052] The above control example implements the same test procedures and test objectives as the experimental example. The results are shown in the following table:

[0053] Table 5: Test results of the control experiment

[0054] Experimental example S / 1 S / 7 S / 14 J X U C1 0.99 0.32 0.42 3.3 4.0 4.0 C2 1.04 0.38 0.50 3.2 3.8 4.1 C3 1.00 0.79 0.85 3.4 2.5 4.0 C4 1.03 0.24 0.37 3.8 4.5 3.7

[0055] In the control series of experiments, the inventors found that when different saponin compounds were used to replace adenosine, the effect of inhibiting oil and fat fluctuated. Although the components were not much different at S / 1, when the waiting time continued, the effect of uridine and cytidine monophosphate as component B decreased appropriately compared with adenosine. Therefore, although uridine and cytidine monophosphate and other saponin compounds can also be used as adenosine compounds, adenosine is the most suitable adenosine component for combination with sodium cocoylaminopropionate and betaine in the experimental scheme of the present invention. Such experimental results may be related to whether the adenosine substance is easy to combine with sodium cocoylaminopropionate and the auxiliary penetration ability of adenosine itself. When adenosine of the adenosine component is applied to the skin, it helps to carry sodium cocoylaminopropionate and betaine to stay inside the pores, and adenosine is likely to promote the growth of a part of the scalp hair follicles, thereby inhibiting the secretion of pore oil and fat for a longer time. Furthermore, the adenosine component of the present invention is important. If only the related component (C3) of A, C, and D is used, betaine cannot well assist and enhance the surface activity of the A component. Meanwhile, adenosine itself has a certain antibacterial and disinfecting effect, which directly affects the effects of the composition in inhibiting oil and preventing dandruff.

[0056] The inventor also unexpectedly found that after adding the anti-dandruff component piroctone olamine salt, there was almost no effect on the test results of anti-dandruff, only a slight improvement in the data of S / 7, and the long-chain piroctone olamine salt component also increased a little greasy sense, resulting in a decrease in the experience of skin contact. Therefore, the composition of the present invention can fully reflect the effect of inhibiting sebum and dandruff regeneration through the appropriate ratio of A, B, and C. In a preferred embodiment, no anti-dandruff, sebum secretion inhibition, disinfection or antipruritic components are added.
