Description

Technical Field

[0001] The invention relates to the field of shampoo products, in particular to a plant extract essence containing Platycladus orientalis leaf extract and a preparation process thereof. Background Art

[0002] Shampoo products are hair cosmetics that are mainly used to wash away the oil secreted by the human body, sweat, cells shed from the scalp, foreign dust, microorganisms, residues of styling products and bad odors attached to the scalp and hair, thereby keeping the scalp and hair clean and beautiful.

[0003] Hair is the hair that grows on the head. It is mainly used to protect the head and is also an important part of head makeup. Thick hair will appear more beautiful, and after various perming and dyeing styles, it can significantly change the appearance and improve people's spirit.

[0004] Hair loss refers to the phenomenon of hair loss. Under normal circumstances, the hair that falls out is mainly in the catagen and telogen phases. Because the hair that enters the catagen and the hair that enters the new growth phase is constantly in a dynamic balance, the normal amount of hair can be maintained. However, when pathological hair loss occurs, abnormal or excessive hair loss will cause the hair to become thin, which seriously affects people's spirit.

[0005] In the fast-paced life, hair loss has become a common phenomenon. People usually choose to use shampoos with anti-hair loss function in the hope of alleviating hair loss and making the hair thick again. Generally, raw materials with anti-hair loss function are added to shampoos with anti-hair loss function, so that when the shampoo is used, the raw materials with anti-hair loss function will be absorbed by the scalp, thereby improving the scalp and alleviating the symptoms of hair loss to a certain extent. However, it is found in practice that the anti-hair loss effect of current anti-hair loss shampoos is relatively general and it is difficult to meet the expectations of consumers. Therefore, there is still room for improvement. Summary of the invention

[0006] In order to improve the efficacy of preventing hair loss, the present application provides a plant extract essence containing Platycladus orientalis leaf extract and a preparation process thereof.

[0007] In a first aspect, the present application provides a plant extract essence containing Platycladus orientalis leaf extract, which adopts the following technical solution:

[0124] Experiment 1

[0125] Anti-shedding experiment

[0126] Recruit a number of volunteers, all of whom are male, with some hair loss, aged 30-40 years old.

[0127] The volunteers were randomly divided into groups, with 10 people in each group.

[0128] The volunteers were divided into groups and used the shampoo to be tested with the plant essence containing Platycladus orientalis leaf extract of each embodiment and comparative example. Each time they used the shampoo, 5 mL of the shampoo was evenly applied on the hair, rubbed for 3 minutes, and rinsed. No other hair care products were used during the experiment.

[0129] Every time you wash your hair, collect all the waste water from the shampooing process, filter out the fallen hair, and calculate the amount of hair loss during the shampooing process after drying. Take the average of the experimental data.

[0130] The volunteers washed their hair every two days, and the amount of hair loss corresponding to the first, seventh and fifteenth washings were recorded respectively.

[0131] Preparation of the shampoo to be tested:

[0132] 11.2 g of sodium laureth sulfate, 1.68 g of sodium lauroamphoacetate, 0.42 g of sodium chloride, 1 g of cocamide MEA, 0.05 g of disodium EDTA, 11.6 g of plant essence containing Platycladus orientalis leaf extract, and 74.05 g of deionized water were mixed evenly to obtain the shampoo to be tested.

[0133] The specific experimental data of Experiment 1 are shown in Table 1.

[0134] Table 1

[0135]

[0136] According to the data comparison of each embodiment and the comparative example in Table 1, each embodiment can better improve the activity of hair follicles through the compounding of Platycladus orientalis leaf extract, Polygonum multiflorum root extract, Zanthoxylum fruit extract, Ginseng root extract, Lilium candidum extract and Ginger extract, and the anti-hair loss effect is faster and better. Although each comparative example uses an extract with anti-hair loss effect to replace Platycladus orientalis leaf extract, Polygonum multiflorum root extract, Zanthoxylum fruit extract, Ginseng root extract, Lilium candidum extract and Ginger extract alone or in full, the coordination system of Platycladus orientalis leaf extract, Polygonum multiflorum root extract, Zanthoxylum fruit extract, Ginseng root extract, Lilium candidum extract and Ginger extract is destroyed, and the characteristic effect of the coordination of Platycladus orientalis leaf extract, Polygonum multiflorum root extract, Zanthoxylum fruit extract, Ginseng root extract, Lilium candidum extract and Ginger extract is lost, resulting in a decrease in the anti-hair loss effect.

[0137] Experiment 2

[0138] According to the 7.5 antibacterial ring method of QB / T2738-2012 "Evaluation Method for Antibacterial and Antimicrobial Effects of Daily Chemical Products", the antibacterial properties of the test samples formed by diluting the plant extract essence containing Platycladus orientalis leaf extract in each embodiment and comparative example were tested.

[0139] The antibacterial effect was evaluated by the diameter of the antibacterial ring. The larger the diameter of the antibacterial ring, the better the antibacterial effect. If the diameter of the antibacterial ring was greater than 7 mm, it was judged to have an antibacterial effect.

[0140] Preparation of test samples:

[0141] Take 10 g of plant essence containing Platycladus orientalis leaf extract and 90 g of deionized water, mix them evenly to obtain a sample to be tested.

[0142] Test strains:

[0143] Microsporum canis, strain number: ATCC 36299, test bacterial suspension concentration 7.8×10 5 .

[0144] Trichophyton tonsurans, strain number: ATCC 10217, test bacterial suspension concentration 7.7×10 5 .

[0145] Malassezia furfur, strain number: ATCC 44344, test bacterial suspension concentration 7.9×10 5 .

[0146] The specific experimental data of Experiment 2 are shown in Table 2.

[0147] Table 2

[0148]

[0149] According to the data comparison of each embodiment and the comparative example in Table 2, each embodiment and the comparative example have better antibacterial effect on Malassezia furfur, and can effectively inhibit Malassezia furfur and thus reduce dandruff, but the antibacterial effect of each embodiment on Microsporum canis and Trichophyton tonsurans is significantly higher than that of each comparative example, and each comparative example barely has an antibacterial effect on Microsporum canis (inhibition ring ≥ 7mm), and has no antibacterial effect on Trichophyton tonsurans (inhibition ring < 7mm). It can be seen that when the Platycladus orientalis leaf extract, Polygonum multiflorum root extract, Zanthoxylum fruit extract, Panax ginseng root extract, Lilium candidum extract, and Ginger extract cooperate with each other, they have a good specific killing effect on the bacteria that cause scalp moss, and can prevent scalp moss infection well. Although each comparative example also has a good antibacterial effect, the killing effect on the bacteria that induce scalp moss infection is poor, and it is difficult to prevent scalp moss infection.

[0150] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
