Description

[0001] The present invention relates to a sunscreen composition comprising Panax ginseng polysaccharide and Green tea polysaccharide,

More particularly, the present invention relates to a composition containing a ginseng polysaccharide and a green tea polysaccharide as an active ingredient and having an excellent ultraviolet shielding effect and a skin damaging effect by ultraviolet rays.

In general, ultraviolet rays contained in the sunlight may cause erythema or dullness by promoting erythema formation or melanin pigment formation in skin cells when the skin is excessively irradiated, and react with sebum secreted from the epidermis to generate lipid peroxides Not only does it cause skin problems, it also causes skin cancer in severe cases. Ultraviolet rays are divided into UV-A (320 to 400 nm), UV-B (280 to 320 nm) and UV-C (200 to 280 nm) depending on the wavelength. Since ultraviolet rays are mostly absorbed in the air, ultraviolet rays that directly affect the human body are known as UV-A and UV-B.

Sunscreen agents that are used to prevent skin damage by ultraviolet rays are preparations that exhibit ultraviolet screening effect by applying a specific substance to a certain skin area. The ultraviolet screening effect is a unit called sun protection factor (SPF) The degree of blocking of the product shall be indicated by using. The ultraviolet screening index is calculated by the FDA (US Food and Drug Administration) formula, which is based on the minimum erythema of UV-B (Minimal Erythema Dose; MED) and UV-B It represents the ratio of the minimum erythemal volume. That is, a natural multiple of the degree to which the skin cuts off ultraviolet rays. The higher the value of the ultraviolet barrier index, the better the sunlight is blocked. However, the higher the ultraviolet barrier agent is, the better. This is because the higher the value of the ultraviolet barrier index, the better the effect, but the worse the skin fit and the higher the side effect.

Sunscreens are largely classified as chemical sunscreens and physical sunscreens. The chemical ultraviolet screening agents using the ultraviolet ray chemical absorption mechanism are well known as organic block agents such as cinnamic acid, salicylic acid and benzophenone. Physical ultraviolet screening agents using the physical scattering and shielding of ultraviolet rays are titanium dioxide, zinc oxide Such weapon blockers are well known. The chemical sunscreen agent has an advantage of ultraviolet shielding effect, but has a narrow wavelength range to be applied, sticky to use in the composition, poor in feeling of use due to bundling, and absorbed into the skin in the form of a molecule, which causes skin irritation . Since most commercialized sunscreen agents contain chemical blocking agents as their main constituents, a high sunscreen index is not desirable. In the case of physical ultraviolet screening agents, ultraviolet rays are reflected and scattered to reduce the amount of ultraviolet rays to be transmitted. Mostly, ultrafine particle type inorganic compounds are mainly used. These materials have a very high refractive index and are superior in heat resistance Do. Skin irritation is relatively low as compared with chemical sunscreen agents, but it has a disadvantage that it causes heavy feeling and whitening phenomenon and is not suitable for cosmetics (Korean Patent Publication No. 2003-0046103).

Various studies have been conducted on the ultraviolet screening agents to overcome the disadvantages of chemical ultraviolet screening agents and physical ultraviolet screening agents. Firstly, a mixture of a chemical sunscreen agent and a physical sunscreen agent in a proper ratio is a method that is mostly applied to present UV screening products, but the above-mentioned fundamental drawback exists. In addition, the form of adsorbing titanium dioxide, which is an inorganic blocking agent, on the surfaces of inorganic or polymeric particles or containing an organic blocking agent in the particles has been supplemented in terms of skin safety but has a disadvantage in that the manufacturing process is complicated and the ultraviolet blocking efficiency is not high. Finally, the inorganic particles such as titanium dioxide and zinc oxide are prepared as ultrafine particles to compensate for the disadvantages of conventional inorganic blocking agents, and the shape with high efficiency blocking effect can not completely reduce the whitening phenomenon. As the particle size becomes smaller, It has disadvantages. Organic and inorganic sunscreen agents based on such chemicals have become a problem of their side effects, so they have become interested in natural sunscreen agents that are harmless to the human body.

In a prior art example of natural sunscreen agents, natural hydroxyanthracene polyglycosides have been reported as sunscreens (Bader et al., Cosmetics & Toiletries, 96 (10), pp67, 1981) Use has been reported in French Patent 2-479-688. Similarly, natural extracts of aloe, frugula, senna, and cascara containing anthraquinone derivatives have also been reported as useful sunscreen agents (Fox et al., Cosmetics & Toiletries, 102 (3), pp41, 1987).

Therefore, the inventors of the present invention have found that when a ginseng polysaccharide derived from ginseng and a green tea polysaccharide derived from green tea are simultaneously used, they have an excellent effect in blocking ultraviolet rays as compared with the case where each of these components is used synergistically .

Accordingly, it is an object of the present invention to provide a composition excellent in ultraviolet shielding effect and skin damaging effect by ultraviolet rays by simultaneously using a ginseng polysaccharide and a green tea polysaccharide.

The light intensity of the ultraviolet rays emitted from the solar simulator lamp to the test site was adjusted to 20-100 mj / cm 2 to examine the back region of the subject. In order to confirm the ultraviolet blocking effect of the sample, the sample was uniformly coated on the back surface of the subject at a thickness of 2 μl / cm 2, left to stand for 15 minutes, and dried. Ultraviolet irradiation windows were attached and fixed to the sample application areas of Comparative Examples 1 and 2 and Examples 1 to 3, and ultraviolet rays were irradiated to other portions except for the irradiation windows by cutting off ultraviolet rays using leather and a towel. The minimum erythemal dose (MED) was determined after 24 hours of irradiation with ultraviolet rays, and the ultraviolet blocking effect was calculated according to the following equation (1). The UVB blocking effect is indicated by the Sun Protection Factor (SPF), which is the blocking index of ultraviolet B, where UV is the amount of ultraviolet light required to produce MED on untreated skin, MED And is calculated by the following equation (1). Therefore, the higher the SPF, the better the UVB blocking effect. The results obtained by the above method are shown in Table 1 below.
