Description

TECHNICAL FIELD The present invention relates to a cosmetic composition for removing sebum containing metal hydroxide,

The present invention relates to a cosmetic composition for removing sebum containing a metal hydroxide.

Since human sebum has a structure similar to that of triglyceride oil, which is useful oil, it does not dissolve well in general water-soluble substance, so it is dissolved in oil having a structure similar to sebum or it is applied to the skin to apply skin- Methods have been used in general. However, conventional degreasing products using the above methods have a limitation in removing only sebum that is exposed on the face by using an oil component, a surfactant, or a substance having an adsorbing ability, and removing sebum in the skin.

The inventors have found that metal hydroxides can expand pores at high pH and effectively adsorb pores in the pores through the extended pores. The present invention provides a cosmetic composition for removing sebum which stabilizes a metal hydroxide in a formulation, which is capable of expanding pores at high pH and effectively adsorbing pores in pores through extended pores.

The present invention provides a cosmetic composition for removing sebum containing a metal hydroxide. Also provided is a cosmetic composition for removing sebum comprising at least one selected from the group consisting of metal oxides and polymer powders, and a metal hydroxide.

By using the cosmetic composition for removing sebum sebum described in the present specification, it is possible to effectively remove sebum in the pores, thereby immediately and continuously reducing the sebum amount.

The cosmetic composition for removing sebum sebum described in the present specification is a cosmetic composition containing a metal hydroxide having a high pH (pH 8 to 9), which removes the aging horny layer at the entrance of the pore which inhibits the normal secretion of sebum upon application of the skin, Is a cosmetic composition for removing sebum which effectively expands the pores in the pores by expanding the size in a short period of time and absorbing the oil.

The metal hydroxide is a substance having a saccharifying action, a laxative action and a slight anti-inflammatory action in the human body, and is used as an antacid or a laxative. The cosmetic composition for removing sebum sebum described in the present specification may contain magnesium hydroxide or aluminum hydroxide. Metal hydroxides generally have a high pH in aqueous solution due to the hydroxyl groups themselves. At high pH, the aging horny layer, which blocks the normal secretion of sebum by blocking the pore opening, changes the tissue state and facilitates removal of the aging horny layer.

The cosmetic composition for removing sebum sebum described in the present specification is an emulsion composition in which a high content of metal hydroxide is stably emulsified in a form so that it can safely act on the skin.

The cosmetic composition for removing sebum sebum described in the present specification may further contain, in addition to the metal hydroxide, a general metal oxide having adsorptivity. In the emulsion composition according to one embodiment, magnesium hydroxide may be contained at 1% by weight or more and common metal oxide at 5% by weight or more. As the metal oxide, titanium oxide, zinc oxide, magnesium oxide, zirconium oxide, cerium oxide or aluminum oxide can be used. In one embodiment of the cosmetic composition for removing sebum sebum described in the present specification, it may further contain a polymer powder having adsorptivity. As the polymer powder, polymethyl methacrylate, polyethylene powder, ethylene / acrylic acid copolymer, polymethylsilsesquioxane, nylon powder or adipic acid / neopentylglycol crosspolymer can be used.

In addition to the pH effects, powdered materials are very large in particle size, making it difficult to produce stable emulsified formulations. The cosmetic composition for removing sebum sebum described in the present invention is effective in adjusting the interaction between powder particles to effectively stabilize nanometer to micrometer sized particles and to improve the stability of the emulsion by increasing the viscosity of the continuous phase of the emulsion, A dispersion stabilizer can be used. As clay mineral substances, clay mineral substances based on organic modified montmorillonite such as montmorillonite, bentonite, hectorite, saponite, phytite, montolorite, bederite, and nontronite can be used.

 The cosmetic composition for removing sebum sebum described in the present specification can be used to disperse and stabilize clay mineral substances after emulsification at a high temperature of from 60 캜 to 100 캜 so as to minimize the collision between the powder particles in the formulation and the occurrence of coalescence even if a collision occurs. So that the powder particles in the formulation can be kept dispersed for a long period of time. The final emulsification temperature is 30 ℃. In addition, a thickening agent may be further added to increase the hardness of the formulation to stabilize the formulation. In addition, triethanolamine stearate (TEA stearate) solution may be added during emulsification to enhance the emulsifying power.

The cosmetic composition for removing sebum according to the present invention may contain 0.1 to 5% by weight of metal hydroxide based on the total weight of the composition. When the metal hydroxide is used in an amount exceeding the above amount, it exceeds the pH standard of cosmetics.

The cosmetic composition for removing sebum according to the present invention may contain 5 to 30% by weight of a metal oxide and a polymer powder based on the total weight of the composition. When the content is less than 5% by weight, the sebum absorption effect is not exhibited. When the content is more than 30% by weight, the emulsion becomes unstable and does not become a formulation.

The sebum removing cosmetic composition described in this specification may contain 1 to 5% by weight of a clay mineral substance based on the total weight of the composition. In the range other than the above content, the powder particles can not be uniformly dispersed in the formulation. Particularly, when the content is less than 1% by weight, the dispersion of the particles becomes uneven due to gravity over time.

The cosmetic composition for removing sebum according to the present invention can simultaneously achieve the effect of opening the pores and the effect of adsorbing the sebum by controlling the pH of the skin, so that the sebum can be effectively removed even by one simple operation.

In one embodiment of the cosmetic composition for removing sebum described in the present specification, magnesium hydroxide is used as a raw material for controlling the pH of the skin. When the magnesium hydroxide is combined with hydrogen ions in the aqueous solution to increase the pH, the cosmetic composition applied to the skin in a high pH state softens and cleanses the keratinized skin after aging. As a result, the aging horny substances existing around the pore opening and covering the pores and accumulating the sebum in the pores are removed, thereby facilitating removal of the sebum in the pores. In addition, magnesium hydroxide has absorption ability and it is applied to the skin, and it absorbs not only the sebum already secreted to the face but also the sebum in the trapped pore which is not secreted. It is possible to more effectively remove the sebum in the pores with the aid of the adsorbing metal oxide and the polymer powder component.

When the cosmetic composition for removing sebum described in the present invention is applied to the skin and washed 10 to 15 minutes later, an effective sebum removal ability can be realized. By eliminating excess sebum that can not be secreted out between the pores and become a source of microbial habit of the skin, people with oily skin and sebaceous glands in the face area can prevent acne, which is more common in women than men.

Hereinafter, the present invention will be described in more detail by way of examples. However, these embodiments are intended to illustrate the present invention and not to limit the scope of the present invention.
