Description

Cream-type cosmetic composition for LED mask {Cosmetic composition of cream type for LED mask}

The present invention relates to a cream-type cosmetic composition for an LED mask, and more specifically, through a cream-type cosmetic composition having an average particle size of 10 to 400 nm, without interfering with the light transmission of the LED mask, It relates to a cream-type cosmetic composition for an LED mask that allows the active ingredient of the cosmetic to penetrate deep into the skin.

Phototherapy for the treatment of skin diseases uses the principle of promoting biochemical reactions within the skin by irradiating light to the skin using various light sources such as sunlight, lasers, fluorescent lamps, and ultraviolet lamps. It is an optical medical technology that treats damaged skin through destruction.

Unlike high-power lasers, the LED light source can be irradiated to a large area of disease with appropriate light output, and the skin treatment technology using the LED light source is similar to the principle in which sunlight is converted into plant cells through chlorophyl in plants. The LED light source is irradiated to induce a photo-biochemical reaction between skin cells. Phototherapy using such an LED light source is based on the absorption of photons from the LED light source into chromospheres or photoacceptors in cellular tissues and promoting metabolic activity of cells. The light absorbed by the cells increases the synthesis of ROS and ATP in the cell tissue, and the cells exposed to red light and near-infrared light release NO. Light with a wavelength selected at an appropriate time and period is absorbed by photoreceptors such as Cytochrome c oxidase in cells, which photodegrades inhibitory NO, promotes enzyme activation, and promotes mitochondrial metabolism and ATP production. Due to this, proteins such as hemoglobin and myoglobin release additional NO, which is a continuous intracellular biochemical reaction.

As a result, LED light irradiation on cells activates the overall metabolic activity of cells and plays a large role in regeneration and rehabilitation of cells. In addition, LED light irradiation can promote the production of collagen and elastin in the skin, suppress the occurrence of wrinkles, and make the skin moist and elastic. In addition, LED light irradiation can exert a significant effect on improving skin diseases. For example, irradiation of LED light, particularly blue LED light, to the skin area where acne has occurred has an effect of improving the overall condition of the skin by extinguishing bacteria that cause acne and subsides inflammation.

Recently, LED masks have been developed and used for the purpose of treating acne on the skin, improving wrinkles, suppressing melanin production, improving spots and freckles, and treating inflammation and wounds through such LED light irradiation. As an example of this, LED masks are published in Korean Patent No. 10-1616707, Korean Patent No. 10-1413646, and Korean Patent No. 10-1710008.

The LED mask is to improve the skin condition through light irradiation with a wavelength of 400 to 900 nm.In order to maximize the effect before using the LED mask, the use of creams and lotions containing various skin functional ingredients is recommended. .

However, in general, emulsified products such as creams and lotions have a particle size of 400nm or more, i.e. 1,000~10,000nm, and when these creams and lotions are used and irradiated with light through an LED mask, LED light penetrates the skin by the particles of the cosmetic composition. Since the scattering is not possible, there is a disadvantage that the effect of improving the skin condition by light irradiation of the LED mask is rather reduced.

Accordingly, there is a need to develop a cream for exclusive use of an LED mask that can significantly improve the skin condition together with the LED light without interfering with the penetration of the light irradiated through the LED mask.

Accordingly, an object of the present invention is to significantly improve the skin condition through the interaction with the light transmission, without interfering with the light transmission of the LED mask, through a cream-type cosmetic composition having an average particle size of 10 to 400 nm. , To provide a cream-type cosmetic composition for an LED mask that allows active ingredients of cosmetics to penetrate deep into the skin.

In addition, by including ceramide as an active ingredient, it is to provide a cream-type cosmetic composition for an LED mask that maximizes the light irradiation effect of the LED mask.

The cream-type cosmetic composition for an LED mask of the present invention for achieving the above object is an emulsion having an emulsified particle size of 10 to 400 nm, and transmits 90 to 100% of light from the LED mask.

It is characterized in that the size of the emulsified particles is 10 ~ 250nm.

It contains ceramide as an active ingredient, and is characterized by showing the effect of improving inflammation and skin barrier through irradiation of red wavelength of 630 to 660 nm.

The cosmetic composition has a viscosity of 10,000 to 50,000 csp, contains polyglyceryl 10-stearate as an emulsifier, and hydrogenated lecithin as an auxiliary surfactant.

Purslane extract, pomegranate extract, fig extract, mulberry fruit extract, ginkgo extract, rocket extract, soybean fermentation extract using Lactobacillus, rice fermentation extract using Lactobacillus, ginseng fermentation filtrate using Lactobacillus, and yeast fermentation It is characterized in that it contains one or more of the filtrate and the fermented filtrate of potato extract using yeast as an active ingredient.

The cream-type cosmetic composition for an LED mask according to the present invention has the advantage of remarkably improving the skin condition by allowing the active ingredient of the cosmetic to penetrate deep into the skin by the light transmission without interfering with the light transmission of the LED mask.

1 is a graph showing the light transmittance of Test Example 2 according to the present invention.

Hereinafter, the present invention will be described in detail.

Conventionally, it has been recommended to apply a cream or lotion type cosmetic composition before using an LED mask, but most of the conventional cream or lotion type cosmetic compositions are emulsions with a particle size of 1,000 nm or more, and LED light is scattered by the emulsified particles. There was a disadvantage that the transmittance was poor. In addition, the solubilized product with a particle size of 1 to 10 nm is mainly a formulation of a lotion, and the content of the active ingredient is limited, and there is a disadvantage that there is not much advantage due to the light irradiation of the LED mask.

Accordingly, the present invention is an LED-only cream-type cosmetic composition, an emulsion having a size of 10 to 400 nm, more preferably 10 to 250 nm, and a transmittance of 90 to 100% of the LED mask light.

In addition, although the cosmetic composition of the present invention has been posted as a cream type, it is sufficient if its viscosity is about 10,000 to 50,000 csp at 20°C. When it has such a viscosity, it has a spreadability and spreadability suitable for use of an LED mask.

That is, when the size of the emulsified particles exceeds 400 nm, the light transmittance is poor because the light transmittance is not good because it is larger than 400 nm, which is the shortest wavelength of the LED mask light, and can reflect and interfere with the light of the LED mask. It is to prepare the formulation. In particular, by providing a cosmetic composition having a particle size of 10 ~ 400nm, more preferably 10 ~ 250nm in order to maximize the light irradiation effect of the LED mask, the light transmittance of the LED mask is 90 ~ 100%.

In the present invention, a method for preparing a cosmetic composition having an emulsified particle of 10 to 400 nm level is not limited, and it is natural that various known methods can be applied. However, during such manufacturing, components that may cause deterioration, discoloration, or side effects due to light irradiation are not included.

As an example, in the cosmetic composition of the present invention, after heating the aqueous phase component, an oil phase component including an emulsifier is gradually added thereto and emulsified to prepare a pre-emulsion, and this is a high pressure homogenizer. It can be produced by homogenizing using.

At this time, it is preferable to use polyglyceryl 10-stearate as the emulsifier, because discoloration, discoloration, and conversion of physical properties do not occur by irradiation with LED light. In addition, the emulsifier is preferably contained in an amount of 0.1 to 10% by weight based on the total amount of the cosmetic composition. This is because if the content of the emulsifier is less than 0.1% by weight, it is difficult to emulsify, and if it exceeds 10% by weight, it is difficult to formulate a cosmetic.

In addition, hydrogenated lecithin may be used in the aqueous phase component as an auxiliary surfactant. The auxiliary surfactant is preferably included in an amount of 0.1 to 2% by weight based on the total amount of the cosmetic composition. This is because if the auxiliary surfactant is 0.1% by weight, emulsification into nanoparticles is difficult, and if it exceeds 2% by weight, the stability of the formulation is deteriorated.

In addition, other emulsifiers or surfactants may also be further included.

In the present invention, as an active ingredient of the cosmetic composition, adenosine as well as various natural extracts, collagen, etc. may be included, and the implementation is not limited thereto.

In particular, as natural extracts, purslane extract, pomegranate extract, fig extract, mulberry fruit extract, ginkgo extract, rocket leaf extract, soybean fermentation extract using lactobacillus, rice fermentation extract using lactobacillus, ginseng fermentation filtrate using lactobacillus, It is possible to use one or more of the fermented filtrate using yeast and the fermentation filtrate of potato extract using yeast. In the case of further containing these natural extracts, it has remarkable functions such as improving skin barrier, improving elasticity, and preventing aging. And these natural extracts may be added in the range of 0.1 to 2% by weight based on the total amount of the cosmetic composition.

The extraction method of such a natural extract may be prepared as an extract using a conventional solvent according to a conventional method known in the field to which this technology belongs, that is, under the conditions of a normal temperature and pressure. As an example, the natural material may be extracted using a solvent selected from the group consisting of water and ethanol, and more specifically, after adding 1 to 20 times the solvent to the dried product of natural material, 1 to 20 hours at 20 to 80 °C It can be prepared by extraction, filtration, concentration and drying. In addition, the fermented extract may be inoculated with Lactobacillus to the extract, fermented at 25 to 35°C for 1 to 7 days, and then filtered.

The cosmetic composition having the above configuration has the advantage of remarkably improving the skin condition by increasing the skin penetration rate of the active ingredient through light irradiation without interfering with the light irradiation of the LED mask.

Meanwhile, the cream-type cosmetic composition according to the present invention may include ceramide as an active ingredient. That is, the present invention contains ceramide as an active ingredient, the size of the emulsified particles is 10 to 400 nm, and irradiation with a red wavelength of 630 to 660 nm is performed, thereby improving inflammation and improving skin barrier by its synergistic effect. It shows the effect. In this case, the ceramide is preferably contained in an amount of 0.1 to 5% by weight based on the total amount of the cosmetic composition.

At this time, since the type of ceramide is not limited, any of ceramide NP, ceramide AP, ceramide NS, and ceramide EOP may be used.

Next, the prepared pre-emulsion was recycled twice at 1,000 bar using a high pressure homogenizer to prepare an emulsion. At this time, the viscosity was 30,000 cps.
