Description

Cosmetic Composition

The present invention relates to a cosmetic composition. More specifically, the present invention provides a powdery, gelled or paste-like powder having excellent skin stimulation effect by reducing the skin irritation and improving the feeling from antibacterial and deodorizing functions containing a mixture of ocher powder and nanosilver, and supplying minerals by ocher powder. It relates to a cosmetic composition.

In general, cosmetics are applied to the skin to provide skin moisturizing and skin flexibility, and to provide skin cosmetic effects and massage effects by creams to promote blood circulation, prevent skin aging, and to adsorb and remove skin wastes. It is used a lot.

Skin is the body's primary barrier and protects against external environmental stimuli such as temperature, humidity, UV radiation, and pollutants. In order to prevent the aging phenomenon of the skin and to maintain a healthier and more beautiful skin, by using physiologically active substances obtained from various animals, plants, and microorganisms in cosmetics, the skin's inherent function is maintained and skin cells are used. Efforts have been made to effectively inhibit skin aging and the deposition of melanin by activating.

Among these efforts, there is a very basic method of absorbing the active ingredient from the skin and delivering the active ingredient inside the skin to act directly on the skin. In this case, it is necessary to select a suitable solvent for many physiologically active substances, and it was difficult to select a solvent that can dissolve these active ingredients. In addition, the skin irritation caused by the solvent and the cosmetics are impossible to control the use of the product is difficult to commercialize, has been extremely limited in recent years.

Later, transdermal absorbents in the form of emulsions were developed to improve the feeling of use and to promote transdermal absorption of the active ingredients. In the early days, nanometer-sized emulsified particles were gradually developed in a manner in which the active ingredient was contained inside the micrometer-sized emulsified particles, and the active ingredient was contained therein.

However, in the case of containing the unstable active ingredient in the emulsion particles as in the prior art, as the emulsion film reaches a dynamic equilibrium state, the active ingredient in the emulsion continuously comes into contact with the water-soluble ingredient of the cosmetic, such as degeneration by oxidation and decomposition. There is a problem that occurs. In addition, the emulsion film is very weak and unstable physicochemically, so that the breakdown of the emulsion film is continued due to contamination by organic or inorganic materials having salts or charges, and may be weak against heat or light. As such, nanometer-sized emulsified particles containing active ingredients using low molecular emulsifiers are not only suitable for use in active ingredients that tend to be unstable in aqueous solution, but also have significant constraints in formulating emulsified particles containing active ingredients. Will receive. In addition, in order to contain a high concentration of the active ingredient must be used in proportion to a large amount of emulsifier, the skin irritation may be caused by the emulsifier.

On the other hand, inorganic salts such as sodium chloride and calcium chloride are salts that exist in vivo, and are important factors in maintaining osmotic pressure and metabolism of skin cells, and are known to help remove skin waste, reduce edema, and improve blood circulation. And the cosmetics which mix | blend an appropriate amount with an inorganic salt according to the characteristic are known.

An object of the present invention is to take the form of the inorganic salt in ocher powder.

Due to the various mineral components and far-infrared radiation efficacy that can be obtained from ocher, the intention is to improve the health of the human body.

Olite or illite extracted from loess contains a large amount of minerals necessary for the metabolism of the human body, and its own properties are excellent in adsorption and biodegradation, and are still effectively used for purification of sewage and red tide.

The skin irritation and the effect of reducing the skin irritation from the antimicrobial and deodorizing function from the ocher powder and the nano-silver, and the use of the mineral supply by the ocher powder is very excellent, thereby improving the skin health of the user.

In order to solve the above problems, the present invention uses the ocher powder and nano silver to reduce the skin irritation and improve the feeling of use from antibacterial and deodorizing functions in addition to the skin cosmetic enhancement effect of the conventional cosmetics, and promote blood circulation by supplying minerals by the ocher powder. Its purpose is to provide cosmetics that greatly enhance and improve.

The present invention, in the conventional cosmetic composition, containing 0.5% to 50% by weight, more preferably, 5 loess in the range of ocher powder and nanosilver in the range of 5 ppm to 500 ppm to enhance the skin cosmetics of the conventional cosmetics In addition to the effects, it is characterized by a cosmetic composition that provides the effect of reducing skin irritation and improving the feeling of use from antibacterial and deodorizing functions and promoting blood circulation by supplying minerals by ocher powder.

That is, the present invention relates to a cosmetic composition containing a mixture containing ocher powder and nano-sized silver fine particles.

In the present invention, the content of ocher powder is applied in the range of 0.5% by weight to 50% by weight, more preferably 5% by weight with respect to the total composition, and the content of nanosilver is in the range of 5 to 500 ppm with respect to the total composition. Use is preferred.

The ocher powder used in the present invention preferably has a size of 1 nanometer to 500 nanometers through a filtration step so that it can penetrate and diffuse to the upper part of the dermal layer when applied to the skin. In this case, the particle size is preferably prepared to have a size of 1 nanometer to 500 nanometers.

If the particle size is smaller than 1 nanometer, skin penetration easily occurs, but it penetrates too deeply into the skin, which makes it difficult to discharge to the outside. In addition, when the particle size is larger than 500 nanometers, there is a problem that the penetration into the skin is inefficient.

 In this embodiment, in order to produce nanoparticles, the emulsion was made into a uniform nano-sized particle using high pressure and high shear force, and a pressure of 500 bar to 2,000 bar was applied, and a flow rate of 20 ml / min to 150 ml / min. Adjusted to.

Surfactants may be used for the preparation of nanoemulsions, which is an intermediate step in primary emulsification and nanoparticle preparation. Surfactants that can be used at this time include anionic surfactants, nonionic surfactants, cationic surfactants and amphoteric surfactants, and include polyvinyl alcohol, carboxymethylcellulose, lecithin, gelatin, polyvinylpyrrolidone, and low molecular alcohols. It is also possible to use it in admixture with the auxiliary surfactant.

The amount of such surfactant can be used in 0.01 to 20% by weight, preferably in the range of 0.5 to 5% by weight.
