Description

  The present invention relates to a composition for skin application, and more particularly to a composition for skin application that can be applied to the skin to clean the skin and make it healthier.

  Conventionally, skin cleansing cosmetics such as facial cleansers are typically known as compositions for cleansing the skin. These cosmetics are washed after application to remove dirt, and then used for general purposes. It is common to use cleansing creams or emulsions that are cosmetics.

  Therefore, it is not only necessary to first apply a conventional skin cleansing cosmetic, wash it after application to remove dirt, and then use a cleansing cream, etc. In addition, the above-mentioned conventional skin cleansing cosmetics are removed after application, so that various nutritional ingredients effective for the skin cannot be blended and soiled. It was only for the purpose of cleaning.

  Particularly noteworthy is the great difficulty that the skin cleansing effect is not always satisfactory despite the above-mentioned drawbacks.

  On the other hand, iron oxide is used as a kind of coloring pigment in cosmetics.

  The problem to be solved by the present invention is to eliminate the difficulty that the cleaning effect of conventional cosmetics for cleaning is insufficient, and the other problems described above. More specifically, by providing a coating composition that has an extremely large cleaning effect, and does not require the use of two types of cosmetics, such as skin cleansing cosmetics and general creams and emulsions, and can also contain nutritional ingredients. is there.

  In order to solve the above-mentioned problems, the present inventor has been intensively researching conventionally, and in this research, general cosmetics such as cleansing creams and emulsions are used in iron powders and iron oxides. After blending and applying this blended product to the skin, by adsorbing iron with a magnet, it is not possible to adsorb skin dirt and waste products at the same time and efficiently clean the skin. This led to a revolutionary idea.

  In order to realize this revolutionary idea, this research is further advanced, and when the content of iron (iron powder and iron oxide) and, if necessary, further emulsifiers are used in combination, dirt on the skin and waste products Has been found to be able to be removed with high efficiency at the time of adsorption of iron by a magnet from the middle of skin pores and tissues, and the present invention has been completed here.

  Iron powder is a component that has never been used in this kind of cosmetics, and iron oxide has been used in cosmetics, especially makeup cosmetics, as a kind of colorant (pigment). It has been done. However, the present invention does not use iron oxide as a colorant, but can adsorb (remove) it with a magnet, and at the same time, it is possible to remove dirt and waste from the skin. Iron oxide is what is used for this purpose. This is a new technique which has been discovered for the first time based on the research of the present inventor, which has not been known at all.

  The iron content used in the present invention is iron powder and iron oxide as described above. According to the inventor's research, this iron powder, like iron oxide, can remove dirt and waste on the skin when adsorbed with a magnet.

Moreover, as this iron powder, what was normally made into the fine particle is used, Preferably the thing of about 100-200 mesh is used. In this case, iron as iron powder includes alloys with other metals and carbon alloys (steel) as long as they can be adsorbed by a magnet, and examples thereof include rare earth compounds and nitrogen compounds.

  Iron powder is usually used in the coating composition in an amount of 0.01 to 85% by weight, preferably 5 to 30% by weight, particularly preferably 10 to 15% by weight.

  There are several types of iron oxides used as another component of iron in the present invention due to their chemical structures, and the raw materials are generally supplied as a mixture of these, and (1) mainly from iron sesquioxide. And (2) black iron oxide mainly composed of iron trioxide, and (3) yellow iron oxide mainly composed of iron oxyhydroxide and ferric hydroxide. In the present invention, these iron oxides are particularly preferably used as a mixture with black iron oxide or other iron oxide containing the same. As this iron oxide itself, those conventionally used as pigments can be widely used, and the particle size and the like thereof may be conventional.

  This iron oxide is usually used in the coating composition in an amount of 0.01 to 85% by weight, preferably 10 to 50% by weight, particularly preferably 20 to 40% by weight.

  If the amount of iron used is less than the normal amount used, the action of removing dirt due to adsorption with a magnet is not sufficient, and conversely if it is increased, it becomes unfit for the skin and lacks cosmetic properties. .

  In the present invention, although it depends on the amount of iron used, it is very preferable to use an emulsifier together.

  As the emulsifier used at this time, any of anionic, cationic, amphoteric or nonionic can be used, and the selection thereof has a correlation with the blending component or composition other than iron oxide. You can choose freely.

  The amount of the emulsifier is usually about 0.5 to 10% by weight, preferably about 1 to 5% by weight, although it depends on the amount of iron used. In particular, in the present invention, it is very preferable to use an emulsifier when the amount of iron used is 3 to 10% by weight, and dirt and waste are removed very effectively and efficiently when the iron is adsorbed by a magnet. I can do it.

  Any magnet can be used in the present invention as long as it can adsorb iron, that is, iron powder or iron oxide, and various magnets are widely used.

  When using a magnet, iron may be directly adsorbed to the magnet, but an appropriate cover may be used. It is also preferable to use the shape as an easy-to-use shape. For example, in order to prevent the iron oxide adsorbed on the magnet surface and the waste of the skin from being applied to the skin surface again, the magnet surface is several millimeters away from the skin A specially designed shape that moves in a moving manner is preferable.

  In the present invention, as the cosmetics to which this iron content is to be blended, so-called general cosmetics such as cleansing creams and emulsions are particularly preferred, but the present invention is not limited thereto, for example, blended with conventional cleaning cosmetics. You may do it. Other examples include paste-type packs and transparent gel type cosmetics.

  Another major feature of the present invention is the ability to incorporate skin nutrients. Conventional cleansing cosmetics were meaningless even if the above-mentioned nutritional ingredients were blended in order to wash and remove them after application. In the present invention, however, by removing dirt and the like with a magnet after application. The main feature is that the blended nutritional components can be sufficiently applied to the skin.

  Therefore, the coating composition of the present invention has both a skin cleansing action and a skin nourishing action, and can be said to be an epoch-making composition for skin application that does not exist at all.

  The nutritional component used in the present invention may be any component as long as it can nourish the skin, and preferred examples include hyaluronic acid, collagen, various herbal extracts and the like.

  What is necessary is just to mix | blend it suitably according to the kind, if the usage-amount can provide a nutrient.

  In the composition of the present invention, various conventionally known additive components that have been conventionally blended in cosmetics are blended as appropriate.

  According to the present invention, it is possible to obtain a coating composition having both a skin cleaning action and a skin nutrition imparting action, and after applying the cleaning cosmetic as in the prior art, it is necessary to wash and use the cream or emulsion again. There is no complication. Moreover, there is a great effect that the cleaning effect is extremely superior to the conventional one.

Hereinafter, the present invention will be described in detail with reference to examples. However, the present invention is not limited to these examples.
