Description

Cosmetics of water insoluble sponge containing cosmetic compositions of sunscreen function

The present invention relates to a cosmetic composition having excellent UV protection provided by impregnating a water-insoluble sponge. More specifically, the present invention is to solve the problem by recognizing that there is a problem that the ultraviolet blocking effect exhibited compared to the total content of the sunscreen contained in the cosmetic composition in the cosmetic composition provided by impregnation with a water-insoluble sponge , It relates to a cosmetic composition that exhibits an excellent sunscreen effect and cosmetics impregnated with the water-insoluble sponge.

Recently, the ozone layer is destroyed due to environmental pollution, and the exposure of ultraviolet rays is intensified. These ultraviolet rays act as a major cause of erythema, edema, freckles, and skin cancer. Accordingly, the development of a product that protects the skin from ultraviolet rays has been recently demanded. In particular, as life becomes rich, not only the desire to protect skin from ultraviolet rays in life, but also the demand for protecting skin from ultraviolet rays increases as the population of leisure activities such as skiing, golf, and sea bathing increases. Research is ongoing.

In general, ultraviolet rays are divided into three regions according to wavelength, wavelengths of 200-290 nm are ultraviolet C (UVC), wavelengths of 290-320 nm are ultraviolet B (UVB), and wavelengths of 320-400 nm are ultraviolet A. (UVA). Among them, UVC passes through the ozone layer and does not reach the surface and disappears, and UVB penetrates to the epidermis of the skin, causing erythema, freckles, and edema. UVA is known to induce skin aging and skin irritation by penetrating the dermis of the skin and promoting skin cancer, wrinkles, and melanin formation.

Long-wavelength ultraviolet light (UVA) promotes skin aging due to degeneration of proteins in the dermal layer, capillary expansion, and destruction of nucleic acids (DNA), and has been identified as a target for vigilance. On the other hand, medium-wavelength ultraviolet (UV-B), which is mostly absorbed from the epidermis of the skin, is called harmful UV rays because it acts rapidly on the epidermis and burns. Long-wavelength ultraviolet rays come into contact with the skin all year round, but because there is no subjective symptoms, the skin ages without knowing it.

As the risk of sun exposure is known, public interest in sunscreen products has increased, and accordingly, products with various sun protection factors (SPF) and sun protection grade (UVA, PA) Is being released.

On the other hand, with regard to the formulation of the cosmetic, the liquid cosmetic has excellent applicability and feeling of use, so it has a high preference, but there is a problem in that it is inconvenient to use and less portable to be spread out by hand. To solve this problem, a low-viscosity emulsified formulation of a liquid cosmetic composition is SBR (styrene-butadiene rubber), BR (butadiene rubber), NBR (acrylonitrile-butadiene rubber), ABS, PE (polyethylene), PVA (polyvinyl alcohol) ), EVA (ethylene vinyl acetate), PU (polyurethane), etc. have been impregnated into foam-insoluble water-insoluble sponges, which have been developed as cosmetics that are easy to use and carry. Among them, cosmetics impregnated with polyurethane sponges have been popularly used. have.

Thus, the present inventors tried to impart a sunscreen function to a cosmetic composition impregnated with a water-insoluble sponge, but when a cosmetic composition having a sunscreen function was impregnated into a water-insoluble sponge, the total content of the sunscreen contained in the cosmetic composition was Accordingly, it was found that there is a problem that the actual sunscreen index / grade is lower than the expected sunscreen index / grade.

In addition, the present inventors have found that the cause of this problem is that the oil-soluble organic sunscreen that is in direct contact with the water-insoluble sponge is adsorbed to the water-insoluble sponge, and as a result, the sunscreen is not discharged at the same concentration as before impregnation. The cause of the problem was identified.

The cosmetic composition according to the present invention includes a sunscreen.

In the specification according to the present invention, the term "ultraviolet ray blocking agent" may include any component that can block ultraviolet rays reaching the skin by a mechanism such as scattering, reflecting or absorbing ultraviolet rays, for example, inorganic sunscreen, organic ultraviolet rays Blockers and mixtures thereof.

Therefore, the cosmetic composition according to the present invention may include an organic sunscreen, an inorganic sunscreen, or a mixture thereof.

The organic sunscreen has the advantage of having an ultraviolet absorbing effect and no cloudiness, and may be classified into an organic sunscreen that is useful, water-soluble, oil-dispersible, or water-dispersible. Examples of oil-soluble or oil-dispersible properties include 4-methylbenzylidene camphor, disodium phenyldibenzamidazoletetrasulfonate, diethylhexylbutamidopriazon, methylenbis-benzotriazolyltetramethylbutylphenol, and ethylhexyldimethyl Pava, glyceryl baba, drometrizole, drometrizoletrisiloxane, digalloyltrioleate, 3- (4-methylbenzylidene) -campa, methylanthranylate, bis-ethylhexyloxyphenolmethoxyphenyltri Azin, diethylaminohydroxy benzoylhexyl benzoate, benzophenone-3, benzophenone-4, benzophenone-8, butylmethoxydibenzoylmethane, cynoxate, ethylhexyltrizone, octylmethoxycinnamate, octocrylene , Octyl dimethylpava, octyl salicylate, oxybenzone, cinnaxate, octyl trizone, ethylhexyl methoxycinnamate, ethyl hexyl salicylate, paraaminobenzoic acid, homosalate, isoamyl-p-methoxycin excited Water-soluble or water-dispersible properties such as yttrium, bis-ethylhexyloxyphenol methoxyphenyltriazine, and polysilicon-15 include terephthalidene dicamper sulfonic acid and its salts, 2-phenylbenzimidazole-5-sulfonic acid, etc. However, it is not limited thereto.

It means one or more (useful organic) sunscreen.

According to the present invention, "the oil-soluble organic sunscreen which is present in the outermost phase but does not adsorb on the water-insoluble sponge" can be implemented by selecting the phase adjustment of the cosmetic composition and / or the composition of the oil-soluble organic sunscreen.

More specifically, by selecting the outermost phase of the cosmetic composition in terms of the phase selection of the cosmetic composition, the effect of the present invention can be achieved. When the outermost phase is aqueous, as described above, for example, a case where Y is a water phase in a single water phase, water-in-oil type, or multiple emulsions ('(X) / (X) n / Y') may be included. When the outermost phase of the cosmetic composition is the aqueous phase, the oil-soluble organic sunscreen present in the outermost phase as the aqueous phase is preferably converted to water-soluble or water-dispersible, or water-soluble or water-dispersible, and if useful or oil-dispersible, encapsulation, etc. It is preferably modified to be dispersible in the aqueous phase by the method.

In addition, in terms of selecting the composition of the oil-soluble organic sunscreen contained in the cosmetic composition, it is possible to use a water-soluble organic sunscreen modified so as not to adsorb on the water-insoluble sponge.

The term "modification" encompasses all chemical or physical modifications of the organic sunscreen, such as a method of preventing direct contact between a water-soluble organic sunscreen and a water-insoluble sponge present on the outermost surface (eg encapsulation of a water-soluble organic sunscreen), Alternatively, a method in which an oil-soluble organic sunscreen and a water-insoluble sponge are brought into contact but the adsorption reaction does not occur (eg, modification of the compound structure, modification to water-soluble / water-dispersible properties, etc.) may be included.

In another aspect, the cosmetic composition according to the present invention includes an organic sunscreen, and the oil-soluble organic sunscreen may be substantially free. The "substantially not included" is less than 10% by weight, less than 9% by weight, less than 8% by weight, less than 7% by weight, less than 6% by weight, less than 5% by weight, 4% by weight relative to the total weight of the cosmetic composition Less than, less than 3% by weight, less than 2% by weight, less than 1% by weight, less than 0.5% by weight, less than 0.05% by weight, less than 0.0005% by weight, or most preferably less than 0.00001% by weight. For example, the content of the useful organic sunscreen contained in the cosmetic composition according to the present invention is less than 10% by weight, less than 9% by weight, less than 8% by weight, less than 7% by weight, compared to the total amount of organic sunscreen included in the cosmetic composition, Less than 6%, less than 5%, less than 4%, less than 3%, less than 2%, less than 1%, less than 0.5%, less than 0.05%, less than 0.0005%, or most preferably 0.00001 It may mean less than weight percent.

The cosmetic composition according to the present invention has an excellent sunscreen effect, preferably at least 30 sun protection factor (SPF) and / or at least 4 sun protection factor (PFA), and sun protection A Protection grade of UVA (PF) ++ or higher. In addition, there is almost no clouding phenomenon.

The “Sun Protection Factor (SPF)” is an index indicating the blocking effect of products that block UVB. The minimum amount of erythema obtained by applying a sunscreen product is the minimum amount of erythema obtained without applying a sunscreen product. It means divided value. The “Minumum Erythema Dose (MED)” refers to the minimum amount of ultraviolet radiation capable of exhibiting erythema in all areas of the irradiated area within 16 to 24 hours after irradiating UVB to human skin.

It is subject to the notice given in Chapter 2 of the Method for Measuring the UV Protection Index (SPF) in Appendix 3 of the Enforcement, 「Regulation on the Evaluation of Functional Cosmetics」.

The “UV A Protection Factor of UVA (PFA)” is an index indicating the blocking effect of products that block UVA. The minimum sustained immediate gain obtained by applying the UV blocking product was obtained without applying the UV blocking product. It means the value divided by the minimum sustained type instantaneous exacerbation. The “Minimum Persistent Pigment Darkening Dose (MPPD)” is the minimum UV dose that detects faint lumping in all areas of the irradiation area within 2 to 4 hours after UVA is irradiated to the human skin. Speak. In addition, "Protection grade of UVA (PF)" means the degree of UVA blocking effect. If PFA 2 or higher, PA is indicated. PFA 2 or higher and lower than 4 are PA +, PFA 4 and higher than 8 and lower are PA ++, and PFA 8 and higher may be labeled as PA +++ (However, the decimal point of the PFA value is discarded and expressed as an integer) Premise). As a method of measuring the UV A blocking index, the subjects are selected, the test site, the minimum sustained type immediate blackening amount before the test, the minimum continuous type instantaneous blackening amount of the product uncoated and coated area, the light source selection, the standard sample, the product applied amount, and the product application area And for the calculation of the area of the irradiation area, the increase in light intensity, and the UV A blocking index, Korea Food and Drug Safety Notice No. 2013-28, 2013.4.5. It is subject to the notices given in Chapter 4 of the UVA blocking index measurement method in Annex 3 of the Enforcement and Regulations on Functional Cosmetics Examination.

As a result of the adsorption test of the sunscreen of the water-insoluble sponge, when an oil-soluble organic sunscreen such as ethylhexyl methoxycinnamate, isoamyl P-methoxycinnamate and ethylhexyl salicylate is in the oil phase (Comparative Example 1-2), It can be seen that the amount of the large amount of water absorbed by the water-insoluble sponge is greatly reduced, and the UV blocking index is greatly reduced. Also, it was found that the main ingredient content was less than 90% under the UV blocking functional cosmetic method, and it was found that there was a legal problem. On the other hand, when using a water-soluble or water-dispersible sunscreen, such as phenylbenzimidazole sulfonic acid (Example 1-2), it was found that it is properly detected without being adsorbed to a water-insoluble sponge. In addition, it was found that it exhibits excellent UV blocking effects of SPF 30 or higher and PFA 4 or higher.

However, in the case of a water-insoluble sponge, the sunscreen adsorption occurs largely in SBR or NBR, and in the case of PU, sunscreen adsorption occurs, but it occurs relatively less than SBR or NBR. Was able to get.
