Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of scalp care, in particular to a cypress-related composition with high anti-dandruff performance and a preparation method thereof. BACKGROUND

[0002] In the field of scalp care, anti-dandruff is one of the core demands of consumers, and the overgrowth of Malassezia is one of the main causes of dandruff. As a natural active ingredient, cypressol has excellent fungistatic properties, especially showing strong inhibition on Malassezia. According to the inhibition zone experiment of Malassezia in the laboratory, the fungistatic effect of cypressol is 5 times stronger than that of piroctone olamine. This property enables the use amount of cypressol, cypress essential oil and cypress extract to be greatly reduced under the premise of achieving the same anti-dandruff effect, which is less than 1 / 2 of the traditional fungistatic anti-dandruff ingredient (such as piroctone olamine), thereby significantly reducing the irritation of the fungistatic anti-dandruff ingredient to the scalp and reducing the occurrence of side effects such as scalp discomfort.

[0003] However, although cypressol, cypress essential oil and cypress extract have the advantage of high efficient fungistatic, there is a prominent problem in the dandruff shampoo containing cypressol: insufficient residual amount after cleaning. During the shampooing process, it is easy to be washed away with the rinsing water, resulting in less retention on the scalp and hair surface, which cannot effectively inhibit Malassezia, and thus the high efficient fungistatic property of cypressol is difficult to fully exert, the anti-dandruff effect is greatly reduced, and the dandruff problem is prone to recur. In the traditional shampoo formula, the surfactants and other ingredients used cannot promote the retention of cypressol and related essential oil extracts on the scalp and hair during the rinsing process, which cannot meet the demand of continuous inhibition of Malassezia.

[0004] In addition, if the addition amount of the active substance is increased in order to compensate for the problem of insufficient residual amount by increasing the initial content, the advantage of "low dosage and low irritation" will be lost, and problems such as increased irritation and increased burden on the scalp may occur, and raw materials are also wasted.

[0005] In summary, in the prior art, the application of cypressol and related essential oil extracts in shampoo must enhance the flocculation and retention performance to truly effectively remain on the scalp for a long time after cleaning, continuously inhibit the colonization of fungi, and fully exert the high efficient fungistatic property. Based on this, it is a technical problem to be solved in the field to develop a shampoo composition that can increase the residual amount on the scalp and hair by compounding specific ingredients under the premise of ensuring safety, thereby enhancing the inhibition of Malassezia and achieving long-term and effective anti-dandruff.

[0033] The compositions of Examples 1 to 6 and the blank control were used to test the Malassezia inhibition zone width using natural wool fiber fabric, specifically, based on the modification of the "Nonwoven Anti-mold Test Experimental Method", the nonwoven fabric was replaced with animal (wool) fiber similar to human hair, and the residual effect of the anti-dandruff agent on Malassezia was evaluated as the indicator bacteria: Instruments and equipment: biological safety cabinet, high-pressure steam sterilization pot, incubator, refrigerator, homogenizer, constant temperature water bath, balance, pH meter, pipette, sterile test tube, sterile plate, fluorescent treated wool fabric, ultraviolet LED lamp, vernier caliper, sterile filter paper, Leeming & Notman culture medium, physiological saline, malt juice agar medium.

[0034] The method is as follows: All biological strains should not exceed 5 generations. Other strains may be added as experimental strains as needed. Test strains equivalent to the following strains may be used from strain collection institutions that are members of the World Federation for the Preservation of Microbial Cultures. Malassezia furfur (ATCC44344) or Malassezia furfur (ATCC14521); inoculate the fungi to be tested onto Leeming & Notman medium and incubate at 36°C for 3-5 days; add 5-10 ml of physiological saline to the culture and repeatedly blow and aspirate to remove the bacterial growth; transfer the bacterial suspension to sterile test tubes using a pipette, shake and mix well to prepare the required concentration for the experiment; take 0.1 ml of the bacterial suspension and spread it onto sterile Leeming & Notman medium; cut fluorescently treated wool fabric into several pieces with a diameter of 50 mm, wash the wool fabric with the example composition, and place it in the culture medium; place the samples extracted from Examples 1-6 and the blank control group in an incubator at 36°C for 1-5 days; measure the invasion range of the bacterial beads on the fabric (mm) using calipers under ultraviolet LED light irradiation. If the invasion range of the bacteria is less than 10 mm, the product has a certain antibacterial effect and dandruff removal efficacy. Products with an antibacterial ring width greater than 10mm have no antibacterial effect and therefore no dandruff-removing efficacy. Please refer to Table 1 for result calculation and effect evaluation: Table 1

[0035] As shown in Table 1, compared with the blank control, Examples 1-6 have the ability to effectively inhibit Malassezia by efficient deposition.

[0036] Furthermore, the amino acid surfactant compound has a gentle cleaning property, while the small molecule cations and large molecule cations can form a protective film on the hair surface, reducing the friction between hair strands, significantly improving the smoothness of wet hair, and improving the combing experience.

[0037] Combing test of artificial hair bundles: The test environment was a temperature of 20℃~22℃ and a relative humidity of 40%~60%RH. Experimental materials and equipment: 12 bundles of undamaged flat hair from Asians (23cm long, 6g in weight), disposable droppers (2ml) or 1ml syringes, 10% AES aqueous solution (active ingredient content), wide and narrow tooth comb (plastic), electronic balance, multifunctional hair testing system (Dia-stron fibra.one), constant temperature and humidity chamber (Stokes ICTHI-250, temperature 24±0.5℃, relative humidity 60±5%), constant temperature and humidity room (temperature 24±2℃, relative humidity 60±5%).

[0038] Test Method (Wet Hair): The Example 1-6 and control hair swatches were thoroughly wetted with flowing, constant temperature water, and 0.2 grams of 10% AES aqueous solution per gram of hair swatch was applied evenly to the surface of the hair swatch for about 30 seconds, and allowed to sit for about 2 minutes, and then rinsed for about 30 seconds. The treated hair swatches were secured in the test position and subjected to combing cycle testing for 6 cycles. The Example 1-6 and control hair swatches after wet hair testing were placed in a constant temperature and humidity environment (temperature 20-22°C, humidity 40-60% RH) for at least 4 hours before use; Example 1-6: The hair swatches that completed baseline combing testing were thoroughly wetted with flowing, constant temperature water, and 0.2 grams of sample per gram of hair swatch was applied evenly to the surface of the hair swatch for about 30 seconds, and allowed to sit for about 2 minutes, and then rinsed for about 30 seconds. The treated hair swatches were secured in the test position and subjected to combing cycle testing for 6 cycles; Control: The control hair swatches that completed baseline combing testing were thoroughly wetted with flowing, constant temperature water, and rinsed for about 30 seconds with water on the surface of the hair swatch. The treated hair swatches were secured in the test position and subjected to combing cycle testing for 6 cycles.

[0039] Example 1-6 and control wet hair combing force test results before and after use are shown in Table 2: Table 2

[0040] Test Method (Dry Hair): The Example 1-6 and control hair swatches were thoroughly wetted with flowing, constant temperature water, and 0.2 grams of 10% AES aqueous solution per gram of hair swatch was applied evenly to the surface of the hair swatch for about 30 seconds, and allowed to sit for about 2 minutes, and then rinsed for about 30 seconds. The treated hair swatches were placed in a constant temperature and humidity environment (temperature 20-22°C, humidity 40-60% RH) for at least 4 hours, removed and secured in the test position, and subjected to combing cycle testing for 6 cycles; Example 1-6: The hair swatches that completed baseline combing testing were thoroughly wetted with flowing, constant temperature water, and 0.2 grams of sample per gram of hair swatch was applied evenly to the surface of the hair swatch for about 30 seconds, and allowed to sit for about 2 minutes, and then rinsed for about 30 seconds. The treated hair swatches were placed in a constant temperature and humidity environment (temperature 20-22°C, humidity 40-60% RH) for at least 4 hours, removed and secured in the test position, and subjected to combing cycle testing for 6 cycles; Control: The control hair swatches that completed baseline combing testing were thoroughly wetted with flowing, constant temperature water, and rinsed for about 30 seconds with water on the surface of the hair swatch. The treated hair swatches were placed in a constant temperature and humidity environment (temperature 20-22°C, humidity 40-60% RH) for at least 4 hours, removed and secured in the test position, and subjected to combing cycle testing for 6 cycles; Descriptive statistics were performed on the measured parameters, including mean, standard deviation, median, maximum, and minimum; SPSS software was used for statistical analysis of the data.

[0041] The dry combing force test results before and after using the examples 1-6 and the blank control group are shown in Table 3: Table 3

[0042] As can be seen from Table 2 and Table 3, compared with the blank control group, examples 1-6 have the ability to improve the wet and dry combing properties.

[0043] Effect after continuous use (scalp tester): The scalp state after 14 days of continuous use was observed using the CK scalp tester; Test population: 1 person aged 39 and 1 person aged 35, both of whom have long-term dandruff and scalp itching problems.

[0044] Principle: The core of the scalp tester is to capture the microscopic image of the scalp through an "optical imaging system", and to convert the invisible scalp problems (such as dandruff and micro-inflammation) into visual images.

[0045] Test method: Wash the hair normally 1-2 days before testing, avoid leaving shampoo / conditioner, and ensure that the scalp is in a dry state; comb the subject's head well, determine the test area, and mark it; gently tease the test area hair to expose the scalp; start the scalp tester, select the 60x lens and install it on the mobile handle; turn on the handle power and adjust the light brightness; gently press the 60x lens on the test area; adjust the focus of the lens to make the image clear; take a picture and save the image; after 14 days, perform the same steps and take a picture in the marked test area, and save the image. Compared with commercially available products and the blank control group, example 2 has more significant anti-dandruff effect on recurrent dandruff, and the commercially available product shows significant redness removal effect on the image. Please refer to Figure 1 .

[0046] In summary, the Taxodium-related composition with high anti-dandruff performance in the above examples, by compounding specific proportions of small-molecule cations and large-molecule cations, combined with amino acid surfactants and synergist compounding, during the water rinse process, these ingredients can synergize with thujaplicin to promote the effective flocculation of Taxodium extract on the scalp and hair surface, significantly increase the residual amount of Taxodium extract, thereby prolonging its action time on the scalp and hair, continuously and effectively inhibiting Malassezia, and improving the durability of the anti-dandruff effect. Using mild small and large molecule cations and compounded amino acid surfactants, while enhancing flocculation, does not increase the burden of flocculation on the scalp, ultimately achieving the anti-dandruff effect of high efficiency, continuous, and solving the dandruff problem from the source of inhibiting Malassezia.
