Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an anhydrous powder type cosmetic composition containing a water-soluble active substance and a polar oil,

The present invention relates to an anhydrous powder type cosmetic composition.

When the skin is exposed to ultraviolet rays, melanin, which determines the skin color of a person, is synthesized and released. In severe cases, hypercholesterolemia such as spots, freckles, and dots are caused. Recently, as the number of people enjoying outdoor activities has increased due to the increase of leisure population, melanin pigmentation due to ultraviolet rays is becoming more intense and hyperpigmentation causes severe mental burden from the viewpoint of skin beauty and hinders normal social activities . From the past, oriental women have preferred white and fine skin, and as an important criterion of beauty, there is a growing demand for prevention and improvement of skin pigmentation abnormalities and hyperpigmentation. Thus, whitening agents that prevent excessive melanin production Development has become necessary and many efforts have been made. Specific examples thereof include inhibitors that inhibit tyrosinase activity, such as kojic acid and arbutin, and hydroquinone, vitamin C and derivatives thereof.

In cosmetics used for external skin, these whitening ingredients are formulated by mixing them in water, which is the most potent polar solvent that can dissolve the ingredients well. This is to allow the water to act as a carrier of the whitening component so as to disperse the whitening component at the molecular level and deliver the active ingredient by mixing with fine gaps or lipids in the skin.

Thus, until now, cosmetic formulations having a whitening effect have been confined to formulations containing water, and in the case of anhydrous formulations such as powdery powder (or compressed powder) which do not contain water, it is thought that the efficacious ingredient can not be delivered to the skin, lost. In particular, in the case of solid make-up cosmetics, since water is contained, various restrictions such as the necessity of an airtight container are often generated.

Therefore, it has been necessary to develop a cosmetic having whitening effect that does not contain water.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a cosmetic composition of a powder-free type by maximizing skin absorption of a water-soluble active substance.

To achieve the above object, the present invention provides a cosmetic composition of a dry powder type containing a water-soluble active substance and a polar oil.

The cosmetic composition of the present invention has a skin whitening effect that suppresses and improves the skin pigmentation phenomenon by inhibiting melanin production of the skin.

Fig. 1 shows a state in which an emulsifying cosmetic is applied to the skin.

The inventors of the present invention invented that it is possible to maximize the skin absorption of a water-soluble effect ingredient by controlling an oil component contained in a small amount as a binder component in general powder (or compressed), thereby developing a whitening powder and a compact powder using a water- .

Generally, when the emulsion type cosmetic is applied to the skin, since the surface of the skin shows hydrophobicity, the oil in the emulsion particles is first adsorbed to the skin at the initial stage of the application, thereby forming a thin oil layer as shown in FIG. This oil layer is the key to mediating skin transmission of the water-soluble active substance, and if the water-soluble active substance has a property of being partially soluble in the oil layer, the oil layer dramatically increases Be able to

This mechanism is as follows. If the partition coefficient from the water of the water-soluble active substance to the skin (or skin lipid) is log Ps / w, Ps / w = Ss / Sw, where P is a function of the solubility S for each medium of the water- In this case, the water solubility of the water-soluble active substance Sw is relatively large compared to the solubility of the skin or the skin lipid component, so that Sw >> Ss becomes, so that the partition coefficient is inevitably lowered. However, when the oil layer Os existing between the skin and the water exhibits a relatively high solubility in the water-soluble active material, it can be more easily distributed thermodynamically. Also, as the relative evaporation amount of water is rapidly removed as time passes, the water-soluble active material present in the water becomes closer to the saturated concentration, resulting in a stronger concentration gradient. At this time, an oil film that maintains the saturated state is formed while the distribution to the oil layer is accelerated.

Accordingly, the present inventors have paid attention to an oil component used for dust (or compressed dust). Generally, powder (or compressed) contains about 5 ~ 15% of oil component. These oils are uniformly dispersed on the powder surface. When powder (or compressed powder) is applied to skin, Likewise, a thin oil film is first formed on the skin surface. Therefore, if a powdery substance (or compressed powder) in which a whitening active substance is dissolved in a supersaturated state is applied to a polar oil in which a water-soluble active substance is partially soluble, an oil layer formed on the surface of the skin, It is possible to maximize the skin absorption of the water-soluble active substance to exhibit the whitening effect.

Hereinafter, the present invention will be described in detail.

One embodiment of the present invention provides a cosmetic composition of the anhydrous powder type containing a water-soluble active substance and a polar oil.

 In one embodiment of the present invention, the water-soluble active substance is one or a mixture of two or more substances selected from the group consisting of gruel extract, cluster extract, mulberry extract, arbutin, ethyl ascorbyl ether, ascorbyl glucoside magnesium ascorbyl phosphate and niacinamide But is not limited thereto. The active substance may have whitening efficacy.

In one embodiment of the present invention, the water-soluble active substance may be contained in a proportion of 0.01 to 10% by weight based on the total weight of the composition, and in the case of a known raw material, a known content may be used. When the content is less than 0.01% by weight, the whitening effect is difficult to exhibit. When the content is more than 10% by weight, skin irritation or stabilization of the formulation becomes difficult.

 In one embodiment of the present invention, the polar oil is used as a binder material, and is one or more selected from the group consisting of fatty alcohols, liquid unsaturated fatty acids, esters oils, and triglycerides. But it is not limited thereto.

 In one embodiment of the present invention, the liquid fatty alcohol may be, for example, oleic alcohol and the like. Nonlimiting examples of the liquid unsaturated fatty acid include oleic acid, linolenic acid, and the like. Esthetic oils include, but are not limited to, Myristyl lactate, Triethyl citrate, Diisostearyl malrate, Polyglyceryl- 2 triisostearate, ethylhexyl methoxycinnamate and the like can be used. As a non-limiting example, triglyceride can be caprylic / capric triglyceride. Preferably, diisostearyl malate and / or polyglyceryl-2 triisostearate are used. These are superior to other oils in skin absorption effect and have a close contact feeling It has the advantage of giving superior usability to the product. The oil used in the present invention can be easily prepared from Cosmol 222, Cosmol 43 provided by Nissin oillio of Japan.

In one embodiment of the present invention, the polar oil may be contained in a proportion of 0.5 to 30% by weight based on the total weight of the composition. If the amount is less than 0.5% by weight, the solubility of the water-soluble whitening raw material tends to be poor and the whitening effect is difficult to obtain. If the amount is more than 30% by weight, the amount of the oil is excessive and the powder is disintegrated.

In one embodiment of the present invention, the cosmetic composition may be a cosmetic composition for skin whitening. In addition, the cosmetic composition may be a cosmetic composition that improves skin pigmentation. In addition, the cosmetic composition may be a cosmetic composition that improves skin dullness.
