Description

Technical Field

[0001] The present invention relates to the field of washing and care products, and particularly to the application of an anti-dandruff and anti-itch composition in the preparation of hair washing or hair care products. Background Art

[0002] The scalp, as the "soil" for hair growth, directly affects the quality of hair and our overall image. With the increasing attention people pay to their own image, they also attach more and more importance to scalp health. Common scalp problems include dandruff, scalp itching, and excessive scalp oiliness. Among them, dandruff directly affects personal image, and scalp itching is often unbearable, bringing a lot of inconvenience and annoyance to people's lives. More importantly, if not dealt with in time, it may also cause more serious scalp problems, such as hair loss and alopecia areata.

[0003] At present, there are various hair washing and hair care products for anti-dandruff and anti-itch on the market. Some add various antifungal drugs, such as common ketoconazole, zinc pyrithione, selenium disulfide, etc. If these drugs are used frequently, while killing fungi, they may also damage normal skin and hair, and are not suitable for long-term use. Chinese herbal medicines are the treasures of traditional Chinese medicine and are widely used in daily health preservation and recuperation in China. If Chinese herbal medicines can be applied in hair washing or hair care products to help people relieve the troubles of dandruff and scalp itching, on the one hand, it can avoid the damage of chemical drugs to the scalp to a certain extent, and on the other hand, it is also beneficial to the development and inheritance of Chinese herbal medicine culture.

[0043] I. Test on the anti-dandruff and antipruritic effects of the anti-dandruff and antipruritic composition

[0044] 1.1 Test on the anti-dandruff effect of the anti-dandruff and antipruritic composition

[0045] The problem of dandruff is a large amount of desquamation caused by excessive proliferation of scalp keratinocytes. Among them, Malassezia is one of the important factors causing dandruff. The increase in dandruff is a mild manifestation of seborrheic dermatitis of the scalp. Due to the proliferation of Malassezia, the scalp becomes oily and the dandruff is severe, and this situation in turn promotes the proliferation of Malassezia. Therefore, adding an anti-dandruff agent to inhibit or kill such microorganisms has a positive effect on inhibiting the growth of dandruff; using Malassezia as the indicator bacterium, the anti-dandruff effect of hair washing products is tested and evaluated. This test method is an in vitro method and is applicable to the evaluation method of the efficacy of dandruff-claiming cosmetics. The correlation between the detection items and the efficacy claims: This method is an in vitro method. Relevant literature shows that the trend of the in vivo method is basically the same as the results of this in vitro method, and the two methods have a certain correlation. Through experimental design, the higher the inhibitory rate value of Malassezia furfur, the stronger the anti-dandruff efficacy of the sample.

[0046] Take the 24-hour fresh slant culture of the test bacteria, wash it off with 0.03 mol / L phosphate buffer solution (PBS), and dilute it with PBS to a bacterial suspension of about 5.0×105 CFU / mL - 4.5×106 CFU / mL for standby. Take a sterile test tube, first add 5.0 mL of the sample (use the stock solution or dilute it proportionally with distilled water according to the requirements of the instruction manual), place it in a water bath at 20°C ± 1°C for 5 minutes, then add 0.1 mL of the test bacterial suspension, mix quickly and start timing immediately. When the test bacteria and the sample interact for the specified time in the instruction manual, respectively pipette 1.0 mL of the test bacteria and sample mixture and inoculate 2 petri dishes, and pour the culture medium. When the number of bacteria cannot be counted, make 10-fold serial dilutions with PBS, select appropriate dilution degrees, respectively pipette 1.0 mL and inoculate 2 petri dishes for viable bacteria culture and counting. At the same time, use PBS instead of the sample for parallel tests as the positive control. The number of recovered colonies in the positive control is between 1.0×104 CFU / mL - 9.0×104 CFU / mL. Take the same batch of PBS and culture medium as the negative control. All test samples and control samples are cultured at 36°C ± 1°C. Observe the final results after culturing the bacterial vegetative form for 48 hours; observe the final results after culturing Malassezia furfur for 72 hours. Repeat the test 3 times and calculate the antibacterial rate.

[0047] Calculate the antibacterial rate:

[0048]

[0049] In the formula:

[0050] X - antibacterial rate, %;

[0051] A0 - the amount of recovered bacteria in the positive control group, in CFU / mL;

[0052] A1 - the amount of recovered bacteria in the test group, in CFU / mL.

[0056]

[0057] 1.2 Anti-dandruff and antipruritic composition antipruritic efficacy test 220 healthy Hartley guinea pigs weighing 250 - 400 g were selected and randomly divided into 22 groups evenly. There were a blank control group (distilled water 0.1 ml / 100 g), a lotion group (positive control group, Sanwei Qingre Zhiyang Lotion 0.1 ml / 100 g), and 20 sample groups (anti-dandruff and antipruritic composition, samples and concentrations are shown in Table 3) with 0.1 ml / 100 g. Two days before the experiment, the hair on the right hind foot dorsum of each group of Hartley guinea pigs was shaved, and the corresponding experimental test substances were applied externally to the shaved area of each group of animals once a day for 2 consecutive days; on the 3rd day, on the experimental day, the shaved area of the right hind foot dorsum of each group of animals was scratched with coarse sandpaper to damage the epidermis until mild skin bleeding occurred, with an area of 1 cm². Then, the corresponding experimental test substances were applied externally locally to each group of animals once again. 10 minutes after the last application of the experimental test substance, 0.05 ml / animal of 0.01% histamine phosphate solution was dropped on the wound surface. After that, every 3 minutes, the concentration was increased in increments of 0.02%, 0.03%, 0.04%..., and each time it was 0.05 ml / animal until the Hartley guinea pig turned back to lick its right hind foot. The total amount of histamine phosphate (μg) given when the Hartley guinea pig finally turned back to lick its right hind foot was used as the itching threshold, and the itching threshold data of each group were recorded. The higher the itching threshold, the better the antipruritic effect.
