Description

Technical Field

[0001] This invention relates to the field of personal care products technology, and in particular to an artemisia shampoo and its preparation method. Background Technology

[0002] With the fast pace of life and increasing environmental pressure, scalp health problems are becoming increasingly prominent, such as dandruff, itchy scalp, excessive oil production, and hair loss. Consumers are increasingly inclined to choose natural, gentle shampoos with multiple conditioning benefits. Mugwort, a traditional Chinese medicine, has antibacterial, anti-inflammatory, antioxidant, and meridian-clearing effects, and its application in shampoo products shows considerable potential.

[0003] Currently, there are some shampoos on the market that contain mugwort, but most of them suffer from problems such as limited efficacy, insufficient extraction of mugwort active ingredients, and unreasonable formulation, resulting in poor actual effects. For example, some products simply add mugwort powder or crude extract, with low levels of effective ingredients, making it difficult to fully exert the conditioning effects of mugwort; other products rely too much on chemical ingredients, which may be effective in the short term, but long-term use may burden the scalp.

[0004] Therefore, it is of great significance to develop a shampoo with mugwort as the main active ingredient, which has multiple hair care benefits, is gentle and non-irritating, and is suitable for long-term use. Summary of the Invention

[0074] Experiment Example 2

[0075] We are recruiting 180 volunteers aged 18-50 with scalp health issues (half male and half female). Inclusion criteria include: dandruff grade ≥2, scalp itching VAS score ≥4, and scalp sebum secretion ≥80μg / cm³. 2 Each shampoo session resulted in hair loss of ≥50 strands. Volunteers had not used antifungal medications, hormonal drugs, or functional hair care products within the past month, and had no history of scalp allergies or other skin diseases. Volunteers were randomly assigned to 6 groups (30 people per group, 15 men and 15 women), using the following methods respectively: Example 1, Example 2, Example 3, Comparative Example 1, Comparative Example 2, and a control (rinsed only with water). There were no statistically significant differences in age, gender, or initial scalp condition among the groups (P>0.05), making them comparable.

[0076] The trial lasted for 4 weeks. Volunteers used the sample shampoo twice a week (Wednesday and Sunday), taking 10 mL of the sample each time. After wetting the hair, the sample was evenly applied to the scalp, massaged for 2 minutes, left on for 30 seconds, and then rinsed off with 40°C warm water. During the trial, volunteers were not allowed to use any other hair care products and were required to maintain a light diet and regular sleep schedule.

[0077] At the start of the experiment (day 0), week 2, and week 4, the following indicators were measured: (1) The scalp on the top and temples was observed using a scalp detector, and the dandruff level was recorded according to the following grading standards: 0: no visible dandruff; 1: very little dandruff; 2: a small amount of dandruff, scattered; 3: moderate dandruff, distributed in patches; 4: a large amount of dandruff, densely covered. The dandruff improvement rate was calculated as follows: dandruff improvement rate = (pre-experiment level - post-experiment level) / pre-experiment level × 100% (if the improvement rate is negative, it is recorded as 0). (2) The visual analog scale (VAS) was used to have volunteers mark the degree of itching on a 0-10 scale (0 = no itching, 10 = severe itching, unbearable). The itch score reduction rate was calculated as follows: itch score reduction rate = (pre-experiment score - post-experiment score) / pre-experiment score × 100%. (3) Use a sebum analyzer to measure the sebum content (μg / cm³) at the same location on the scalp (5cm from the center of the top of the head). 2 ). Calculate the sebum reduction rate, sebum reduction rate = (sebum content before experiment - sebum content after experiment) / sebum content before experiment × 100%. (4) Collect fallen hair with a filter during shampooing and weigh it with an electronic balance. Calculate the hair loss reduction rate, hair loss reduction rate = (hair loss per instance before experiment - hair loss per instance after experiment) / hair loss per instance before experiment × 100%. (5) Observe the volunteers' scalp daily during the experiment for any irritation reactions such as redness, swelling, stinging, or increased itching. Record the irritation incidence rate, irritation incidence rate = number of people experiencing irritation reactions / total number of people in each group × 100%.

[0078] The results of the usage are recorded in Table 2.

[0079] Table 2 Results of Usage Effect

[0080]

[0081]

[0082] Table 2 shows that volunteers using the products of Examples 1-3 of this invention exhibited significant effects in improving dandruff, relieving itching, controlling oil production, and reducing hair loss, with effects superior to the comparative and blank control groups. Example 1 showed the best results, with the highest overall improvement rate. Furthermore, the incidence of irritation was extremely low in all example groups, indicating that the products of this invention are mild, non-irritating, and highly safe.

[0083] Therefore, this invention, by combining artemisia essential oil and artemisia ethanol extract in a specific mass ratio, fully leverages the synergistic effect of volatile and non-volatile active ingredients in artemisia, significantly enhancing its inhibitory ability against common scalp pathogens such as Staphylococcus aureus, Escherichia coli, and Malassezia. This effectively improves the scalp's microecological environment, reducing dandruff, itching, and other problems. The shampoo of this invention shows significant effects in improving dandruff, relieving itching, controlling oil production, and reducing hair loss, and is especially suitable for people with excessive dandruff, itching, excessive oil production, and mild hair loss.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
