Description

[0001] The present invention relates to an ultraviolet ray blocking cosmetic composition comprising a sericite synthetic material,

The present invention relates to an ultraviolet barrier cosmetic composition, and more particularly, to an ultraviolet barrier cosmetic composition using a serpentine synthetic material, which can safely use a skin barrier for which skin barrier cosmetics are difficult to use due to toxicity of organic materials, Which is a disadvantage of the coloring cosmetics, thereby maximizing the feel and color feeling of the color cosmetics.

Recently, ozone depletion due to environmental pollution has increased, and as a result, it has become an environmental problem, and as a result, it is exposed to ultraviolet rays to increase skin premature aging, skin cancer and the like.

In general, the ultraviolet screening agents used for cosmetic use are broadly classified into organic ultraviolet screening agents and inorganic ultraviolet screening agents. Examples of the organic ultraviolet screening agents include parasol-MCX systems having a conjugation bond capable of absorbing ultraviolet light in a molecular structure methoxycinnamate) ultraviolet absorber. However, PASOL MCX, which is an organic UV-ray blocking agent, has disadvantages such as skin toxicity, allergy and discoloration, and recently, an inorganic UV blocking agent has been used instead of an organic UV blocking agent.

On the other hand, the inorganic ultraviolet screening agents mainly have an ultraviolet shielding effect by scattering ultraviolet rays. Typical inorganic ultraviolet screening agents are metal oxides such as TiO 2, CeO 2, ZnO, and ZrO 2 having high refractive index. Among them, TiO2 is widely used because of its relatively low price and strong ultraviolet shielding ability due to a very high refractive index (2.5). However, due to inherent bad skin feel and strong cohesiveness of TiO2, primary nano- , There is a problem in use that secondary particles (micro size) are produced, and skin adhesion and ultraviolet shielding effect are drastically lowered.

Therefore, various studies have been conducted on the emulsification of TiO2 particles in order to prevent the coagulation phenomenon of TiO2. However, it is very difficult to emulsify nano-sized TiO2 particles in the water or oil phase in the form of nano-sized particles, Even when emulsified, there were many problems in maintaining product stability when these nano-sized TiO2 particles were incorporated into cosmetics finished products.

In order to solve various problems in using such nano-sized TiO2 as a UV-blocking material in cosmetics,

(1) A method for producing a composite powder comprising the steps of (1) activating the inside / outside of an inorganic powder or organic resin with an acid to form the maximum OH group (2) by increasing the molar ratio of the water / titanium alkoxide and the alcohol / titanium alkoxide to the inorganic powder or organic resin activated by the inside / outside of the titanium alkoxide during the hydrolysis of the titanium alkoxide, And (3) filtering, washing, drying and surface modifying the slurry, wherein the inorganic powder is selected from the group consisting of silica, silica gel, alumina, mica, sericite, talc, And the organic resin paper is selected from nylon, polymethyl methacrylate, polyethylene, polystyrene, and the acid Is selected from inorganic acids such as nitric acid, hydrochloric acid, sulfuric acid and hydrofluoric acid. "

However, the above prior art and prior art have attempted to hydrolyze titanium alkoxide by sol-gel method to coat TiO2 on the substrate surface, besides the conventional simple mixing method of inorganic powder and TiO2 or organic resin and TiO2, Uniform nano-sized TiO2 can not be coated on the substrate, and secondary aggregation of the TiO2 particles produced results in improved transparency, skin feel, skin adhesion, and ultraviolet shielding effect substantially as compared with simple mixing of a substrate and TiO2 There was a limit that could not be done.

The present invention relates to prior art and prior art sunscreen cosmetics comprising conventional titanium dioxide,

Regarding ultraviolet protective ability, titanium dioxide shows a large absorption capacity (about 0.02 탆) as the primary particle diameter is smaller (around 0.02 탆), and has a slightly larger primary diameter (about 0.10 to 0.20 탆) in the UV-A region in the UV-B region It has a disadvantage of having a large scattering ability,

Accordingly, when a particle having a small diameter and a particle having a small diameter is used in combination, ultraviolet ray protection in both regions is expected. However, when such a composition is used, transparency deterioration of the preparation can not be avoided.

In addition, when the particle diameter is small and the non-surface woven fabric is large, it has a strong cohesive force and is not good in dispersibility. Since blue color is easily scattered in visible light,

A cosmetic composition for preventing ultraviolet rays and cosmetics containing the same, which can solve the above-mentioned problems and reduce whiteness when using cosmetics with ultraviolet rays, is provided.

The present invention also provides an ultraviolet barrier cosmetic composition having a high antioxidative function of skin, excellent skin safety and affinity for skin, and having a high ultraviolet shielding effect, and a cosmetic product containing the same.

In order to solve the above problems and needs,

(EN) Disclosed is a cosmetic composition for ultraviolet ray shielding comprising a sericite synthetic material prepared by adsorbing or coating titanium dioxide (TiO2) on the surface of a sericite.

The present invention also provides a UV-blocking cosmetic composition characterized in that the above-mentioned sericite has a particle diameter of 0.5 to 2 占 퐉 and the particle diameter of titanium dioxide is 0.05 占 퐉 to 0.1 占 퐉.

The present invention also provides a cosmetic composition comprising a cosmetic composition comprising the sericin synthesis material prepared by mixing 5 to 20 parts by weight of a sebum absorbing material composed of clay, talc, silica, starch or a mixture thereof.

The present invention also provides a UV-blocking cosmetic comprising the UV-blocking cosmetic composition.

The UV-blocking cosmetic composition according to the present invention can be replaced with an ultraviolet-ray absorbing agent, and the skin-disease patient who has difficulty using cosmetics with ultraviolet blocking due to the toxicity of the organic material can be safely used.

In addition, it is possible to eliminate the blue-whitening phenomenon which is a disadvantage of titanium dioxide, which is a conventional ultraviolet screening agent, to create an effect of maximizing feeling and color feeling as a color cosmetic product.

In addition, the ultraviolet shielding cosmetic composition according to the present invention can improve the ultraviolet shielding function by the surface modification of the sericite and titanium dioxide to protect the skin from harmful ultraviolet rays

The ability to be doubled.

In addition, the cosmetic composition for protecting ultraviolet rays according to the present invention is a composition of cosmetics using sericite, which is a far-infrared ray radiating substance, directly irradiated far infrared rays to the skin to help skin health, and also has a remarkable effect on prevention of skin aging.

1 is a conceptual diagram of a mixing apparatus according to the present invention;

Hereinafter, the present invention will be described in detail with reference to the drawings.

The present invention provides an ultraviolet shielding cosmetic composition comprising a serpentine synthesis material produced by adsorbing or coating titanium dioxide (TiO2), which is an inorganic ultraviolet scattering agent, on the surface of the sericite.

[Table 1] shows the advantages and disadvantages of the titanium dioxide in the form of particle size and under the preparation of the ultraviolet shielding cosmetic product.

size Advantages Disadvantages 0.20 탆 or more Hiding power is great.
Good lubricity. The ultraviolet blocking effect is lowered. 0.10 to 0.20 탆 UV-A blocking effect is great.
Hiding power is adequate. UV-B blocking effect is small. 0.10 탆 or less UV-B blocking effect is great.
Good transparency. The crease is unnatural in white.

Regarding ultraviolet protective ability, titanium dioxide shows a large absorption capacity (about 0.02 탆) as the primary particle diameter is smaller (around 0.02 탆), and has a slightly larger primary diameter (about 0.10 to 0.20 탆) in the UV-A region in the UV-B region It has large spawning ability.

When a combination of a particle having a small diameter and a particle having a small diameter is used in combination, it is expected that ultraviolet rays are protected in both regions. However, if such a particle is used, transparency deterioration of the preparation can not be avoided.

Further, when the particle diameter is small and the non-surface woven fabric is large, it has a strong cohesive force, and therefore the dispersibility is poor and the blue color is easily scattered in visible light. Therefore, it is necessary to develop the technology and the manufacturing method for reducing the white sensation when using the ultraviolet shielding cosmetics.

Therefore, the present invention is characterized by using a minerals having the highest emissivity of far-infrared ray, that is, sericite, in order to radiate far-infrared rays from cosmetics to help skin health.

The term "sericite" of the present invention is also referred to as sericite, which is a generic name of a fine-grained, fine-grained vinyl-shaped muscovite. It belongs to monoclinic, white or grayish white with pearl luster. Originally referred to as crystalline schist and sericite schist, in particular, clay-like fine muscovite formed by hydrothermal action.

If the fine sericite powder retains the unique characteristics of the sericite, that is, it retains the thin film of the sericite, it can maintain soft texture and silk gloss as well as far infrared ray emission, quick drying, moisture generation, It can be used as an expanding agent for products and drugs, so that the added value is maximized.

The sericite used as a raw material for cosmetics is used as a formulating agent and a coloring agent in cosmetics. The group name of the silicate mineral is the same as that of the silicate mineral but has a similar physical property but a variety of chemical compositions.

The present invention has a technical feature in a method for producing a sericite synthetic material produced by adsorbing or coating titanium dioxide (TiO2), which is an inorganic ultraviolet scattering agent, on the surface of the above-mentioned sericite, and furthermore, It is a technical feature that it is used as a cosmetic composition.

The present invention is prepared by pulverizing a sericite with a particle diameter of 0.5 to 2 탆 and preparing a titanium dioxide particle having a particle diameter of 0.05 탆 to 0.1 탆.

Particularly, the technical feature of the present invention is that the above-mentioned sericite is a gold seric persimmon.

The Geuncheon sericite of the present invention is a sericite mined in Ochon, Chungcheongbuk-do. Its emissivity is significantly higher than other sericite in other areas, and it is characterized by its excellent minerals and its beneficial effect on the human body.

The present invention relates to a technique for adsorbing and coating 1/10 titanium dioxide particles on a sericite having a diameter of about 10 times larger than that of a grain, and adopting a dry method without using a wet or planetary mill, do.

In the present invention, 50 to 150 parts by weight of titanium dioxide is mixed with 100 parts by weight of sericite, and the resultant mixture is put into a mixing apparatus 100 and physical force is applied to perform a process of adsorbing or adhering titanium dioxide on the surface of the sericite.

As shown in FIG. 1, the mixing apparatus 100 of the present invention includes a mixing unit 110, a vibration motor unit 120, a low tension compression spring unit 130, and a buffer spring unit 140.

As shown in FIG. 1, after the sericite and titanium dioxide are mixed and introduced into the mixing part 110, the vibration motor part 120 is used to lower the low tension compression spring part 130 ) To apply physical pressure along the longitudinal axis to the particles. As the vibrating force has the rotational force, the mixed particles are evenly mixed while rotating, resulting in collision between the particles.

At this time, titanium dioxide having a cohesive force is adsorbed or attached to the sericite particles having a plate-like structure and having a large adsorption capacity and a large specific surface area.

When the above process is performed for about 60 minutes to 75 minutes, the adhesion ratio between the two particles is maximized. The adhesion ability of titanium dioxide is about 33% and the titanium dioxide in the individual state is about 67%. This overcomes the limitations of the ultraviolet blocking ability of each particle size of titanium dioxide and the restriction of feeling of cosmetic use per particle size.

In other words, the blue color of the titanium dioxide particles is reduced by the characteristic of the coloring agent of the sericite, and the ultraviolet scattering ability of each particle size is complemented by the grain size of the sericite.

This enhances the ultraviolet shielding ability and enhances the feeling of use of cosmetics.

In addition, due to the far-infrared radiation ability of the sericite, the heat and the light energy absorbed from the outside of cosmetics are radiated again to the far infrared ray to directly irradiate the skin, thereby activating the skin cell tissue to prevent aging, promote metabolism, And prevention of mold propagation.

<Practical Test Example>

1. Synthesis test of sericite and titanium dioxide

In the present invention, the effect of ultraviolet ray shielding was examined by experimenting with a sericite synthetic material prepared by adsorbing or coating titanium dioxide (TiO2), which is an inorganic ultraviolet scattering agent, on the surface of the sericite.

This test was carried out to evaluate the function and performance of the sericite composites synthesized from sericite and titanium dioxide.

The UV protection index was measured by SPF (in vitro), and the feeling was evaluated by evaluating 5 items for the feeling of use by 1 to 10 points for 6 female panelists and calculating the average value thereof.

As shown in [Table 2], the sericite synthetic material synthesized from the sericite and titanium dioxide produced by the above-mentioned method was improved from 25 to 32 in comparison with the raw material in which the sericite and titanium dioxide were simply mixed, and the feeling was improved from 4.67 to 6.77 Respectively.

Sample SPF Feeling S1 (simple mixing) 25 4.67 S2 (surface modification of the solution) 32 6.77

2. Functional evaluation of cosmetics by mixing of sericite and titanium dioxide

In this test, titanium dioxide was measured in a fixed amount and the amount of the sericite was increased by a certain amount, thereby measuring the ultraviolet shielding ability, the far infrared ray emissivity, and the feeling of use.

As shown in the results of Table 3, every 5% increase in the composition of sericite showed a quantitative improvement in ultraviolet shielding function and an increase in the far-infrared emissivity. The feeling of use also increases.

As a result, it can be seen that the function of the cosmetic product is improved as the composition of the sericite is increased. However, when the amount of the sericite is increased beyond the ratio of the titanium dioxide, the shape of the cosmetic product is problematic. .

Sample SPF Far-infrared emissivity Feeling S1 20 86.3 4.27 S2 29 88.2 4.30 S3 19 88.4 5.93 S4 35 88.6 6.20 note)
