Description

Cosmetic composition for scalp care

The present invention relates to a cosmetic composition for scalp care, and more particularly, it removes oil and sebum generated from the scalp, provides a calming effect on the scalp and improves scalp redness, and suppresses scalp odor and hair loss by improving the scalp temperature. It relates to a cosmetic composition for scalp care that can prevent .

In modern society, the living body is gradually damaged due to a lot of stress, and hair loss due to this is a big social issue. Hair loss is caused by various factors, such as poor hair growth and lack of growth factors that promote the growth of hair follicle cells.

Hair loss refers to a state in which hair is lost or lost, and the number of human hair is about 100,000 to 150,000, and has its own cycle of anagen, catagen, and telogen, and repeats growth and fallout. On average, about 100 hairs are naturally lost per day. Although the exact mechanism of hair loss has not been elucidated, the research so far has shown that excessive sebum production due to endocrine system abnormalities such as hormonal imbalance, circulatory system abnormalities such as autonomic nervous system and blood circulation disorders, nutritional deficiency of hair roots, allergies, bacterial infection, heredity Environmental factors such as environmental factors, mental stress, air pollution or food, and aging are presumed to be the causes. Alopecia occurred only in the middle-aged in the past, but recently, it is also occurring frequently in young people in their 20s and 30s.

In particular, the heat generated from the crown expands the pores of the scalp and promotes the secretion of sebum, thereby oxidizing wastes and generating bad odors as well as being pointed out as a factor that accelerates hair loss.

Among the conventional drugs for promoting hair growth for treating such alopecia, products approved for their efficacy as a hair loss treatment agent by the US Food and Drug Administration (FDA) to date include oral finasteride from Merck in the United States and Upzone in the United States. There are two types of topical application Minoxidil from Upjohn. Minoxidil has a capillary dilatation function, so it prevents hair loss by applying it to the scalp. The effect is insignificant, and side effects such as itching and irritation appear. Finasteride has an inhibitory effect on the production of male hormone DHT (5α-dihydrotestosterone), which causes hair loss. There was a problem with returning to the original state. In addition, side effects include decreased libido and decreased sexual function such as erectile dysfunction.

On the other hand, the above-mentioned background art is technical information that the inventor possessed for the derivation of the present invention or acquired in the process of derivation of the present invention, and it cannot be said that it is necessarily a known technique disclosed to the general public before the filing of the present invention. .

[Table 1]

[Check antibacterial effect]

In order to confirm the antibacterial effect of the Examples and Comparative Examples 1 to 6, a bacterial detection test was performed.

에서 48시간 동안 배양한다. 48시간 뒤 건조필름 배지에 형성되는 집락수를 판독하여 균수의 변화율을 계산하였다. 그 결과를 하기 표 2에 나타내었다.Add 9 mL of sterile water to 1 g of each sample and make a 10-fold dilution solution mixed evenly using a homogenizer. After transferring the sample diluted solution to a sterilized test tube, inoculate Staphylococcus aureus, Escheria coli, and Candida albicans to a concentration of 3.0Х102 CFU/mL, respectively, and mix using a Voltex Mixer. . After inoculating 1mL of the completed sample solution on dry film medium, transfer it to an incubator 35

incubate for 48 hours. After 48 hours, the number of colonies formed on the dry film medium was read to calculate the rate of change in the number of bacteria. The results are shown in Table 2 below.

[Table 2]

As shown in the above results, the decrease in the number of bacteria was the highest in Example and Comparative Example 3 containing all of citric acid, dimethyl sulfone, volcanic cones, sugar citron peel extract, and bokbunja by-products, in particular, whether bokbunja by-product extract was contained. It can be seen that there is a significant difference in the rate of decrease in the number of bacteria depending on whether or not there is. Therefore, the composition for cleaning the vulva of the present invention exhibits an antibacterial effect by removing harmful bacteria.

[Itching and soothing effect]

In order to confirm the antibacterial effect of Examples and Comparative Examples 1 to 6, a hair loss prevention evaluation experiment was performed on a total of 35 subjects in their 20s and 50s. The subjects were divided into 7 groups (Examples, Comparative Examples 1 to 6), and they were used to wash the scalp in the evening once a day for 8 weeks. After use, the degree of improvement was determined according to the opinions of the subjects, and the results are shown in Table 3 below.
