Description

A sunscreen cosmetic composition comprising an essential oil ingredient having an insect repellent effect {SUNSCREEN COMPOSITIONS INCLUDING ESSENTIAL OIL PREVENTING INJURIOUS INSECT}

The present invention relates to a sunscreen cosmetic composition comprising a plant-based essential oil component having a pest repellent effect, by containing a plant-based essential oil component having a repellent effect against various pests, such as mosquitoes in the sunscreen cosmetics that are commonly used during outdoor activities In addition, the present invention relates to a cosmetic composition that simultaneously provides an advantage of preventing sun access along with sun protection.

Ultraviolet rays irradiated from sunlight are known as a major cause of erythema, edema, freckles, and skin cancer. Recently, many studies on various skin diseases caused by ultraviolet rays have been actively conducted.

Generally, ultraviolet rays are classified into UVC (240-280 nm), UVB (280-320 nm), and UVA (320-400 nm) depending on the wavelength. UVC passes through the ozone layer and disappears without reaching the surface. UVB penetrates the skin's epidermis, causing erythema, freckles, and edema. In addition, UVA is known to induce skin aging and skin irritation such as penetrating the dermis of the skin to promote skin cancer, wrinkles, melanin formation. In addition, a number of epidemiological studies have demonstrated a strong correlation between sun exposure and human skin cancer.

Accordingly. The public's interest in sunscreen products in relation to sun exposure has increased considerably, and various sunscreen products have been developed and sold.

On the other hand, in summer there are many restrictions on outdoor activities due to various pests as well as ultraviolet rays. There are more than 3,000 mosquitoes in the world, and among them, about 500 species of tropical striped mosquitoes (Aedes), 300 species (Culex) and more than 350 species of Anopheles are known to harm humans. Harwood, RF and MT Jame. 1979. Entomology in Human and Animal Health, Macmillan.). There are 51 known mosquitoes in Korea, including 20 tropical striped mosquitoes, 18 mosquitoes, and 7 terrestrial mosquitoes.

Mosquitoes not only suck blood from humans and livestock, but also cause many lives, including malaria, encephalitis, yellow fever, and dengue fever. Today, two-thirds of the world's population is exposed to mosquito-borne diseases. Moreover, the mosquito vampire is a pest that directly or indirectly causes a lot of damage by acting as a stress source such as disturbing sleep and limiting outdoor activities.

Accordingly, there have been attempts to kill or drive away mosquitoes for a long time. In particular, the use of insect repellents in the concept of killing insects has always been a problem of potential toxicity to the human body, so research has been conducted to avoid insects hate from the concept of killing insects themselves. Many researchers have synthesized and screened thousands of compounds, resulting in N, N-diethyl-m-toluamide (DEET), which is still widely used as an insect repellent. . However, DEET has been shown to have a repelling effect and an unpleasant smell only when its amount is used in an amount of 15 to 20% by weight or more, and may have harmful side effects when used (WO 91 / 1511A1), in particular, eyes, mucous membranes, It is known to be dangerous to sensitive skin.

In other words, in order to use as insect repellent harmless to humans and livestock, the effect should last for a long time, there should be no irritating or unpleasant smell and safe for sunlight or oxygen, it is difficult to meet all of these conditions.

Furthermore, in the summertime, sunscreens are applied to protect the skin from ultraviolet rays, and insect repellents are additionally applied. In this case, in addition to inconvenience, there is a disadvantage in that the sustainability is poor. Therefore, there is a need for a sunscreen product that can be applied at a time while being harmless to the human body and has excellent sustainability of insect repellent effect.

An object of the present invention is to provide a sunscreen cosmetic composition that is harmless to the human body, has a repelling effect against mosquitoes and various pests, and excellent in its durability.
