Description

A cosmetic composition for UV-screening containing Corn Bran Extract}

The present invention relates to a sunscreen cosmetic composition containing a corn bran extract, and more particularly to a sunscreen cosmetic composition containing a corn bran extract extracted from corn bran and a polyamine conjugate derived from the corn bran extract (polyamine conjugates) It relates to a sunscreen cosmetic composition containing.

In general, when UV rays are excessively irradiated directly on the skin, it may cause erythema formation or melanin pigmentation in skin cells, causing spots and blemishes, and peroxidation in response to sebum secreted in the epidermis. The production of lipids can cause skin problems and, in severe cases, can cause skin cancer. UV rays are classified into UV-A (320-400 nm), UV-B (280-320 nm), and UV-C (200-280 nm) depending on the wavelength. Are known as UV-A and UV-B.

Exposure to ultraviolet light increases free radical formation and the generation of reactive oxygen species (ROS) in the skin and induces oxidative stress on cellular components such as DNA, membranes, and proteins. It is known to cause aging.

The sunscreens used for the purpose of preventing skin damage by ultraviolet rays are classified into chemical sunscreens and physical sunscreens.

Chemical blocking agents that act as chemical absorption of ultraviolet rays are well known organic blocking agents such as cinnamic acid, salicylic acid, and benzophenone, and physical blocking agents that act as physical scattering and shielding of ultraviolet rays are inorganic such as titanium dioxide and zinc oxide. Blockers are well known. Chemical blockers have the advantage of excellent UV-blocking effect, but has a disadvantage of causing skin irritation because it is narrow in the wavelength range applied, and is applied to the cosmetic in a sticky and bundley feeling and molecular form when applied to cosmetics. In the case of physical blockers, skin irritation is relatively low compared to chemical blockers, but has the disadvantage of causing heavy feeling of use, whitening and phototoxicity.

In order to compensate for the above disadvantages of the chemical and physical blockers, various studies on sunscreens have been conducted, and in particular, studies on natural sunscreen ingredients having advantages in skin safety have been actively conducted. As a technology developed in this regard, Korean Patent Nos. 10-0526637, 10-0858630, 10-0114124, and 10-0162282, etc., contain natural ingredients extracted from drawing, green beans, coffee, pansy, rhubarb, etc. A sunscreen cosmetic composition has been developed.
