Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cosmetic composition containing a water-insoluble sponge and a UV-

The present invention relates to a cosmetic composition having an excellent ultraviolet shielding function provided by impregnation with a water-insoluble sponge. More specifically, the present invention recognizes that there is a problem in that the cosmetic composition provided by impregnation with a water-insoluble sponge has a problem in that the ultraviolet shielding effect exerted against the total content of the ultraviolet screening agent contained in the cosmetic composition is inferior, , A cosmetic composition exhibiting an excellent ultraviolet shielding effect, and a cosmetic product in which such a cosmetic composition is impregnated with a water-insoluble sponge.

Recently, the ozone layer has been destroyed due to environmental pollution and exposure to ultraviolet rays has been intensified. Such ultraviolet rays are a major cause of causing erythema, edema, freckles, and skin cancer in the skin. Accordingly, there has recently been a demand for development of a product that protects skin from ultraviolet rays. Especially, as the life becomes more and more, not only the desire to protect the skin from living ultraviolet rays but also the demand for protecting the skin from the ultraviolet rays is increasing as the leisure activity population such as skiing, golf, and bathing water is increased. Research is underway.

In general, ultraviolet rays are divided into three regions according to wavelength, ultraviolet C (UVC) at a wavelength of 200-290 nm, ultraviolet B (UVB) at a wavelength of 290-320 nm, and ultraviolet A (UVA). Among them, UVC passes through the ozone layer and disappears without reaching the surface. UVB penetrates into the epidermis of the skin, causing erythema, freckles and edema. UVA penetrates the skin's dermis and promotes skin cancer, wrinkles, and melanin formation, leading to skin aging and skin irritation.

The long wavelength ultraviolet (UVA) has been designated as a boundary object by promoting skin aging by protein denaturation in the dermis, capillary expansion, and destruction of DNA (DNA). On the other hand, the medium-wave ultraviolet (UV-B), which is mostly absorbed in the epidermis of the skin, is called harmful ultraviolet rays because it rapidly acts on the epidermis and burns. The long wavelength ultraviolet rays reach the skin all year round, but because they do not have any subjective symptoms, the skin becomes old without knowing oneself.

As the risk of exposure to sunlight became known, public interest in UV protection products increased, and accordingly, products with various sun protection factor (SPF) and protection grade of UVA (PA) Is being released.

On the other hand, regarding the formulation of cosmetics, there is a problem that liquid cosmetics are excellent in spreadability and feeling, and have a high preference, but are inconvenient in use and should be portable. For solving such problems, a liquid cosmetic composition which is a low-viscosity emulsion is mixed with a styrene-butadiene rubber (SBR), a butadiene rubber (BR), an acrylonitrile-butadiene rubber (NBR), an ABS, a polyethylene (PE) ), EVA (ethylene vinyl acetate), PU (polyurethane), etc., which have been impregnated with water-insoluble sponge, and developed as a cosmetic product that is easy to use and carry. Among them, cosmetics impregnated with polyurethane sponge are popularly used have.

The present inventors have attempted to impart ultraviolet shielding function to a cosmetic composition impregnated with a water insoluble sponge. However, when a cosmetic composition having an ultraviolet shielding function is impregnated with a water-insoluble sponge, the total content of the ultraviolet screening agent It is found that there is a problem that the ultraviolet barrier index / grade actually displayed is lower than the expected ultraviolet barrier index / rating.

In addition, the inventors of the present invention have found that the cause of this problem is that the oil-soluble organic UV-blocking agent in direct contact with the water-insoluble sponge is adsorbed on the water-insoluble sponge and consequently the UV-blocking agent is not discharged at the same concentration as before impregnation, .

In the cosmetic composition according to the present invention, the inventors of the present invention have found that the added ultraviolet blocking function can not be exerted fully because the ultraviolet blocking agent is adsorbed on the water-insoluble sponge. Accordingly, the present inventors have solved the problem by controlling the content or shape of the organic UV-blocking agent of the cosmetic composition, and more preferably, by controlling the content or shape of the UV-blocking agent in the outermost layer of the cosmetic composition, We want to solve this problem.

Accordingly, the 'ultraviolet screening agent other than the oil-soluble organic ultraviolet screening agent' included in the cosmetic composition of the present invention is an ultraviolet screening agent other than the oil-soluble organic ultraviolet screening agent, A sunscreen agent, etc.), content, or position in the cosmetic composition, regardless of the adsorption on the water-insoluble sponge, a person skilled in the art can appropriately select it.

For example, when the single phase is composed of a single phase (that is, single phase or single phase), the single phase is referred to as the outermost phase. In the case of the water-in-oil type emulsion, the outermost phase is the oil phase. Is referred to as '(X) / (X) n / Y' (where 'X' and 'Y' may be water phase or oil phase, Y 'is the outermost phase, for example, in the oil-in-water type (O ₁ / W / O ₂ ), the outermost phase is the "oil phase (O ₂₎ '.

When the water-insoluble sponge was found to have an oil-soluble organic UV-blocking agent (Comparative Example 1-2) such as ethylhexylmethoxycinnamate, isoamyl P-methoxycinnamate, and ethylhexylsalicylate, It was found that the UV blocking index significantly decreased due to the large amount of water absorbed by the water - insoluble sponge, and it was found that the content of the main ingredient was less than 90% according to the UV blocking functional cosmetic law, which is also a legal problem. On the contrary, when a water-soluble or water-dispersible ultraviolet screening agent such as phenylbenzimidazole sulfonic acid was used (Example 1-2), it was detected without being adsorbed on the water-insoluble sponge. In addition, it was found that SPF 30 or more and PFA 4 or more show superior ultraviolet shielding effect.

However, in the case of water-insoluble sponge, the ultraviolet ray blocking agent adsorption occurs largely in SBR or NBR. In case of PU, the ultraviolet ray blocking agent adsorption occurs, but it is relatively less than SBR or NBR and is superior to that of SBR or NBR sponge .
