It relates to a composition for shampoo.

The composition for foot shampoo of the present invention has a positive effect such as antibacterial, anti-odor, and moisturizing effects on feet that sweat a lot and have thick skin, while expressing a good scent and maintaining clean foot health.

Chamaecyparis obtusa used in the present invention is an evergreen coniferous tree belonging to the Cupressaceae family. In Japan, cypress has been widely used as a valuable tree that has been familiar to people since ancient times, and is called "Hinoki". Similarly, in Korea, it is also widely used as a wood material that is beneficial to health.

Cypress tree leaves mainly contain terpenes, the main components of which are alpha-pinene and limonene, and essential oils extracted from cypress trees relieve stress, provide psychological stability, and improve cardiopulmonary function. It is reported to be effective in strengthening and bronchial asthma. In addition, cypress essential oil has an itching effect in atopic dermatitis and has antibacterial activity against skin microorganisms.

Cypress trees are known to contain a lot of phytoncide, and the use of phytoncide is increasing as it is known to be helpful for psychological stability, strengthening cardiopulmonary function, and strengthening the heart. The main component of these phytoncides is terpene, a volatile organic compound, which not only produces a forest scent, providing a forest bathing effect, but is also beneficial to the human body and has various functions such as antibacterial, insect repellent, and deodorizing properties.

It is the most common type of athlete's foot, and occurs most often in the fourth toe between the fourth and fifth toes, followed by the third toe. This is because this area is anatomically closed and does not allow air to pass through well, so moisture is not easily dissipated and humidity is maintained well. Severe itching, excessive sweating, and unpleasant foot odor may occur. The skin between the interphalanges becomes white, cracked, dry, and scaly, and over time, it may spread to the toes and soles of both sides. Additionally, secondary bacterial infection can occur through damaged skin.

Additionally, athlete's foot can occur in scattered vesicles on the soles or sides of the feet and can merge to appear in various sizes and shapes. The vesicles are filled with yellow serous fluid, and when dried, they form a thick yellow-brown crust and leave erosions when scratched. When you sweat a lot in the summer, the growth of dermatophytes becomes active, which tends to worsen, and when blisters form, it becomes very itchy.

In addition, athlete's foot occurs all over the soles of the feet, and in dry cases, dead skin cells of normal skin color thicken and fall off like fine powder when scratched. It is also chronic, intractable, and has few noticeable symptoms.

This type of athlete's foot can be infected or the symptoms can become worse through hot and humid climates such as those on the feet, working environments, sweat, poor nutrition, contact with infected people, etc. It is transmitted through skin peelings or toenail scraps from athlete's foot patients in bathrooms, swimming pools, etc. In particular, it is a chronic recurrent disease in which mold parasitizes and reproduces by dissolving the dead skin cells of the skin and using them as nutrients. It occurs in warm places with high humidity and rich dead skin cells that fungi like.

These bacteria that cause athlete's foot include Trichophyton rubrum, which accounts for 60% of athlete's foot cases, and Trichophyton mentagrophytes , which accounts for 20%. The causative bacteria may vary depending on the site of occurrence, patient age, etc. .

According to a preferred embodiment of the present invention, the Cypress extract can exert a strong resistance effect against athlete's foot fungus, and this effect can be even more effective when mixed with a grapefruit extract.

In addition, grapefruit (Citrus paradisi Macf.) used in the present invention is a fruit belonging to the citrus family and contains a lot of vitamins, minerals, and fiber, and especially beneficial ingredients such as flavonoid, vitamin C, carotenoid, citric acid, and limonoid. They are abundant.
