Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cosmetics, and particularly relates to a dandruff-removing and hair-puffing composition and a preparation method thereof. BACKGROUND

[0002] The current consumer's core demand for scalp health management focuses on the improvement of dandruff, sebum and itching problems, which directly promotes the market dominance of dandruff-removing and itching-relieving shampoo products. Malassezia, as a lipophilic fungus, is confirmed as the core pathogen causing pathological symptoms such as dandruff and scalp itching. This flora lacks the ability to synthesize endogenous fatty acids, but can hydrolyze host sebum by secreting lipase, phospholipase and sphingomyelinase, and decompose lipids such as triglycerides into free fatty acids for its metabolic proliferation. In this process, irritating metabolites are continuously produced, including unsaturated fatty acids (such as oleic acid), free fatty acids and indole derivatives; directly damage the tight junction structure of the stratum corneum, destroy the skin physical barrier; interfere with the normal differentiation program of sebaceous gland cells; induce abnormal proliferation and accelerated metabolism of keratinocytes; cause a vicious cycle mechanism of feedback hypersecretion of sebum, neurogenic inflammation-mediated itching, and deterioration of the hair follicle microenvironment leading to dandruff.

[0003] The main dandruff-removing functional shampoos currently mainly use zinc pyrithione (ZPT), menthol and other chemical synthetic substances as functional ingredients, which have the hidden dangers of sensitization and irritation, and in order to achieve good dandruff-removing effect, the content is generally above 0.5%. Patent documents with publication numbers CN 111388365 A and CN 108815084 A both record the use of high content of ZPT and / or menthol to achieve the expected dandruff-removing and itching-relieving effect. However, long-term or high-concentration use can easily lead to damage to the scalp barrier, imbalance of flora, and even induce the defect of drug resistance.

[0004] Replacing chemical synthetic dandruff-removing agents with plant extracts is a new research direction. Patent document with publication number CN 106806194 A records a dandruff-removing shampoo composed of soapberry extract, rosemary extract, tea tree oil, lavender extract, chamomile extract, ginseng extract, angelica extract, radix polygoni multiflori extract, rabdosia amabilis extract, platycodon grandiflorum extract and dispersing agent. However, the use of plant extracts alone has limited dandruff-removing and cleaning effect, and can easily lead to a decrease in hair puffiness and poor use experience. SUMMARY

[0005] In view of the shortcomings and deficiencies of the prior art, the primary purpose of the present application is to provide a dandruff-removing and hair-puffing composition.

[0006] Another purpose of the present application is to provide a preparation method of the above-mentioned dandruff-removing and hair-puffing composition.

[0046] The compositions obtained in the above examples and comparative examples are tested and evaluated for the following properties:

[0047] I. Anti-dandruff efficacy

[0048] 1. Experimental principle and basis

[0049] Most studies have shown that microbiological factors and local immune responses play a major role in the pathogenesis of dandruff. It is now generally accepted that the overgrowth of microorganisms dominated by Pityrosporum ovale is one of the important factors.

[0050] The antibacterial test is tested according to 7.3 Antibacterial effect test method (suspension quantitative method) of antibacterial effect evaluation method for daily chemical products in Chinese National Standard QB / T 2738-2023. Through the antibacterial test, it is judged that the sample to be tested has an effect on Malassezia furfur. The antibacterial rate greater than 50% indicates that the product has an antibacterial effect, that is, the dandruff removal effect, and the higher the antibacterial rate, the better the effect.

[0051] 2. Test steps

[0052] 2.1, determine the sample action concentration and action time;

[0053] 2.2, add 0.1 mL of Malassezia furfur bacterial suspension and mix well, start timing for 20 min, dilute appropriately, take 1 mL of 2-3 dilutions, respectively, and place in two parallel flat dishes, then add the corresponding culture medium and mix well, and culture at 30℃ for 4d. The above experiment is repeated three times, and the average number is taken, and a blank control is set at the same time;

[0054] 2.3, after 4d of culture at 30℃, count the colonies and calculate the antibacterial rate.

[0055]

[0056] In the formula: I - average number of colonies of the control group; II - average number of colonies of the test group; the result is retained to two decimal places.

[0057] The dandruff removal efficacy test results are shown in Table 4 as follows:

[0058] Table 4

[0059] Test sample Example 1 Example 2 Example 3 Comparative Example 1 Comparative Example 2 Comparative Example 3 Bacteriostatic rate 99.98% 99.98% 99.99% 99.92% 99.87% 99.80%

[0060] As can be seen from the results in Table 1, the specific ratio of soapberry extract, supramolecular salicylic acid, menthol and PCA zinc used in the present application is used as a dandruff functional component, which can synergistically improve the dandruff removal efficacy of the obtained shampoo. After lacking any of the above synergistic efficacy components, the dandruff removal efficacy of the obtained shampoo is significantly reduced.

[0061] II. Bulky efficacy

[0062] 1. Evaluation basis and principle

[0063] The experiment is based on the basic definition of the lofting effect, and the internal laboratory method "Q / GDFX44-2025 hair product lofting effect test method" is formulated. The friction between the hair produces electric charge repulsion, so that the originally soft hair produces a kind of lofting effect. In this method, the lofting effect is represented by comparing the area of the hair bundle before and after using the tested product.

[0064] 2. Test method

[0065] Before using the product: the test hair bundle is fully wetted with flowing clean water, treated with cleaning liquid, and then placed in a constant temperature and humidity box (20-25℃, 40-60%) for more than 4 hours. After taking out and fixing in the test position, the hair bundle is photographed and the area is analyzed.

[0066] After using the product: the test hair bundle is fully wetted with flowing clean water, evenly used on the surface of the hair bundle according to the sample usage instruction, and the usage time is about 30 seconds. After standing for about 3-5 minutes, it is washed and placed in a constant temperature and humidity box (20-25℃, 40-60%) for more than 4 hours. After taking out and fixing in the test position, the hair bundle is photographed and the area is analyzed. Blank control group: clean water.

[0067]

[0068] In the formula: S0 is the area of the hair bundle before using the product; S1 is the area of the hair bundle after using the product.

[0069] The lofting effect test results are shown in Table 5:

[0070] Table 5

[0071] Test sample Example 1 Example 2 Example 3 Comparative Example 1 Comparative Example 2 Comparative Example 3 Control group Loftiness 28.76% 25.34% 26.52% 17.60% 20.15% 29.07% -1.38%

[0072] As can be seen from the results in Table 2, the sapindus extract and supramolecular salicylic acid have obvious synergistic effect on the improvement of the lofting effect of hair products. The reason is that the surface activity and oil control property of the sapindus extract and the oil control and keratin regulation property of the salicylic acid have synergistic effect.

[0073] The above examples are the preferred embodiments of the present application, but the embodiments of the present application are not limited by the above examples. Any changes, modifications, substitutions, combinations and simplifications made without departing from the spirit and principles of the present application are equivalent replacement methods, and are included in the protection scope of the present application.
