UV protection patch{PATCH FOR INTERCEPTING ULTRAVIOLET}

The present invention relates to a UV-blocking patch, and more particularly, to a UV-blocking patch that can effectively block UV rays than a UV-blocking agent for application, as well as excellent adhesion, adhesion and lasting power, and having cooling and soothing effects. Will.

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

In general, UV rays are classified into UV-C for 240 to 280 nm, UV-B for 280 to 320 nm, and UV-A for 320 to 400 nm, depending on their wavelength. UV-C is known to pass through the ozone layer and disappear without reaching the ground surface, and UV-B is known to penetrate to the epidermis of the skin and cause erythema, freckles, and swelling. In addition, UV-A is known to induce skin aging and skin irritation, such as promoting skin cancer, wrinkles, and melanin formation by penetrating into the dermis of the skin, as well as a number of epidemiological studies that have a relationship between sun exposure and human skin cancer. It is also proven to be.

Recently, as interest in sun exposure has increased, the general public's interest in UV-blocking products has increased considerably, and accordingly, various UV-blocking products are also rapidly developing.

The UV protection products have been released in a variety of skin-applied products, such as sun cream, sun spray, and sun stick.These products are used to protect skin from sunburn, cancer, photoaging, etc. As used, it should be uniformly applied to the skin, chemically and physically stable enough for long-term storage, and should not be easily removed by sweat or water after application to the skin, as well as, in particular, non-toxic to skin tissue, and skin irritation and skin It can be said that its excellence is evaluated according to the degree to which the excellent UV blocking function is exhibited in the absence of trouble and cloudiness.

However, in practice, the above-described skin-applied sunscreen has a limitation in the formulation of the sunscreen material due to dispersing power, skin troubles, cloudiness, and the like, so that the sunscreen effect is not so great. In addition, as the sunscreen must be applied at regular intervals from time to time, its use is cumbersome.

As a result, even though most people use sunscreen, pigmentation, fine lines, and spots due to photoaging easily occurred.

Therefore, in order to solve this disadvantage, Korean Patent Registration No. 10-0781808 proposes a mask for blocking ultraviolet rays. However, since the pre-registered patent has to be covered with a mask, there is a disadvantage in that it is frustrating and uncomfortable when used, and it is not good to look at it, making it difficult to use.

In addition, Korean Patent Registration No. 10-1371987 proposes a patch for attachment including a UV blocking function. However, the pre-registered patent has a disadvantage in that it is not easy to use because the patch is attached to the location because the UV blocking rate is partially different, and the manufacturing cost is also high and marketability is not good.

In addition, Korean Laid-Open Patent Publication No. 10-2017-0138778 proposes a UV-blocking patch that can be personalized, but there is a disadvantage in that skin trouble may be caused by the adhesive layer by forming a separate adhesive layer on the patch.

This UV-blocking patch can be applied to the cheekbones, under the eyes, forehead, as well as to each part of the human body that needs UV protection. Since it is not an application type, it does not get on your hands and can be easily attached outdoors. Also, since it is not applied, it is convenient in use.

On the other hand, the hydrogel patch of the present invention can block ultraviolet rays by the hydrogel patch even if it does not separately include a sunscreen agent, but may further include a sunscreen agent in order to maintain the ultraviolet blocking rate for a long time.

The sunscreen agent safely protects the skin from exposure to ultraviolet rays during indoor and outdoor activities, and at least one of an organic sunscreen and a natural sunscreen may be used without limitation.
