Description

Cosmetic composition for blocking blue light and ultraviolet rays {Cosmetic Composition for UV and Bule-light Protection}

The present invention relates to a cosmetic composition containing a plant extract extracted from a plant containing lutein, and relates to a cosmetic composition that blocks short-wavelength blue light (blue light) and ultraviolet rays.

The sunscreen market has experienced rapid growth in recent years. Ultraviolet rays reaching the ground are divided into UVA (320~390nm) and UVB (290~320nm) according to the wavelength. It is known to do Therefore, it affects connective tissue such as collagen and is a direct cause of skin photoaging, Taichi, M et al. In the study of Fragrance Journal, 43, p31, 2015., research on the transmission of UVA wavelengths through windows is progressing, and the importance of UVA blocking is highlighted. Regarding PA (Protection Factor for UVA) marking, the UVA protection index, the regulations have been changed from PA+++ to PA++++.

In addition, studies on the harmfulness of short-wavelength blue light in the vicinity of the ultraviolet A region, that is, blue light having a wavelength of 380 to 500 nm that emits blue light within visible light, are being actively conducted. Short-wavelength blue light, that is, blue light, refers to the blue and violet spectrum of the High-Energy Visible Light (HEV Light) band. PLoS One. Sep 2013 In 17;8(9)e73678 , blue light has less energy than ultraviolet light but has high skin permeability and is harmful. Among the blue light range, violet light (410nm) is a photoreceptor expressed in keratinocytes By overexpressing rhodopsin mRNA, the phosphorylation of CREB (cAMP esponsive element binding protein) is reduced, and the mRNA expression level of Keratin-10 (K10) and Keratin-1 (K1), which are specific keratinocyte differentiation markers, is reduced. It has been reported that it reduces the differentiation of human keratinocytes and delays the recovery of the damaged skin barrier.

Blue light is also included in solar light, but since 2010, as smart devices have spread in earnest, TVs, computer monitors, and smartphones have been exposed to blue light for a long time. Therefore, studies on cosmetics having the effect of blocking blue light are being actively conducted.

Patent Publication KR10-2017-0003391 discloses a patent for a cosmetic composition containing jade powder to block blue light, but in the case of jade powder, it is an inorganic powder that has a heavy feeling of use and is difficult to use for sun gel type. There is a problem in that it is difficult to evenly block short-wavelength blue light if it is not uniformly dispersed through blocking.

Accordingly, the present inventors completed the present invention as a result of repeated research on the development of a sunscreen cosmetic that blocks blue light at the same time as ultraviolet rays due to the short-wavelength blue light absorption property of lutein, which is present in large amounts in plant chloroplasts.

On the other hand, in the present invention, lutein seed oil used for lutein extraction has a high content of oleic acid, linolenic acid, etc., so it has antifungal activity, is effective in alleviating eczema and rough skin, and is known to inhibit melanin pigment.
