Description

Cosmetic composition of anhydrous powder type containing water-soluble active substance and polar oil {THE ANHYDROUS POWDER TYPE COSMETIC COMPOSITION CONTAINING WATER SOLUBLE ACTIVE INGRADIENTS AND POLAR OIL}

The present invention relates to a cosmetic composition of the dry powder type.

When exposed to UV light, melanin (melanin), which determines the color of a person's skin, is synthesized and released, and in severe cases, hyperpigmentation such as blemishes, freckles, and spots. In recent years, the increase in leisure population has led to the increase in the number of people who enjoy working outside, and the phenomenon of melanin pigmentation caused by ultraviolet rays is intensifying, and hyperpigmentation is a serious mental burden from the viewpoint of skin beauty, which can interfere with normal social activities. . In addition, Asian women have long favored white and fine skin, and this is an important criterion for beauty, and there is an increasing demand for prevention and improvement of abnormal skin pigmentation and hyperpigmentation, and whitening agent that prevents excessive melanin production. Development was needed and much effort has been made in the meantime. Specific examples thereof include inhibitors that inhibit tyrosinase activity such as kojic acid, arbutin, hydroquinone, vitamin C, and derivatives thereof.

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

Thus, until now, cosmetic formulations with whitening efficacy have been limited to formulations containing water, and in anhydrous formulations such as powdered (or compressed) powders that do not contain water, it is thought that skin delivery of the active ingredient is impossible and the whitening function cannot be exerted. lost. In particular, the solid make-up cosmetics often contain water, and thus, many restrictions have arisen, such as the need for an airtight container.

Therefore, there was a need to develop a cosmetic having a whitening effect containing no water.

The present invention aims to provide an anhydrous powder type cosmetic composition by maximizing the skin absorption of the water-soluble active substance in order to solve the above problems.

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

The cosmetic composition of the present invention has a skin whitening effect of suppressing and improving skin pigmentation by inhibiting melanin production of the skin.

Figure 1 shows the state when applying the cosmetic of the emulsion type on the skin.

The present inventors have developed the whitening powder powder and the compressed powder using the water-soluble active substance by inventing that the skin absorption of the water-soluble efficacious raw material can be maximized by controlling the oil component contained in a small amount as a binder component in the general powder powder (or compressed powder). Was done.

In general, when the emulsion-type cosmetics are applied to the skin, the skin surface shows hydrophobicity, so that the oil in the emulsion particles is first adsorbed to the skin to form a thin oil layer as shown in FIG. 1. This oil layer is the key to mediating the skin delivery of the water-soluble active substance. If the water-soluble active substance has a property of being partially soluble in the oil layer, the oil layer dramatically increases the skin transfer of the water-soluble active substance. I can make it

This mechanism is as follows. When the distribution coefficient of water-soluble active substance from water to skin (or skin lipid) is log Ps / w, if P is a function of solubility S in each medium of the water-soluble active substance, Ps / w = Ss / Sw, In this case, Sw, the solubility of water-soluble active substance in water, is relatively large compared to solubility in skin or skin lipids, so that Sw >> Ss is inevitably lowered. However, when the oil layer Os existing between the skin and the water exhibits a relatively high solubility in a relatively water-soluble active substance, it may be easier to thermodynamically distribute. In addition, as time passes, when water having a large relative evaporation rate is removed faster than oil, the water-soluble active substance present in the water phase approaches the saturation concentration, thereby showing a stronger concentration gradient. At this time, while the distribution to the oil layer is accelerated to form an oil film to maintain a saturated state.

Accordingly, the inventors have paid attention to the oil component used for the powdered powder (or compressed powder). Generally, the powdered powder (or compressed powder) contains about 5 to 15% of oil, which is dispersed evenly on the surface of the powder. When the powdered powder (or compressed powder) is applied to the skin, Similarly, a thin oil film is first formed on the skin surface. Therefore, when the powdered powder (or compressed powder) in which the whitening active material is dissolved in a supersaturated state in the polar oil in which the water-soluble active material is partially dissolved, the active material is formed as an oil layer formed on the skin surface according to the partition coefficient. It is possible to maximize the absorption of the skin of the water-soluble active substance by the distribution of the whitening effect.

Hereinafter, the present invention will be described in detail.

One embodiment of the present invention provides a cosmetic composition of the dry 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 two or more mixtures selected from the group consisting of bark extract, matsutake extract, mulberry extract, arbutin, echyl ascorbyl ether, ascorbyl glucoside magnesium ascorbyl phosphate and niacinamide It may be, but is not limited thereto. The active substance may have a whitening effect.

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

 In one embodiment of the present invention, the polar oil is used as a binder material, one selected from the group consisting of liquid fatty alcohols, liquid unsaturated fatty acids, ester oils and triglycerides, or It may be a mixture of two or more, but is not limited thereto.

 Liquid fatty alcohol in one embodiment of the present invention can be used as a non-limiting example, oleyl alcohol, and the like, non-limiting examples of the liquid unsaturated fatty acid, oleic acid, linolenic acid may be used. Ester oils include, but are not limited to, Myristyl lactate, Triethyl citrate, Diisostearyl malrate, Polyglyceryl-2 triisostearate (Polyglyceryl- 2 Triisostearate), Ethylhexyl Methoxycinnamate (Ethylhexyl Methoxycinnamate) and the like can be used, triglycerides can be used as a non-limiting example, Caprylic / Capryl Triglyceride (Caprylic / Capric Triglyceride). Preferably, diisostearyl malrate and / or polyglyceryl-2 triisostearate may be used, which have a good skin absorption effect and a close contact with other oils. It has the advantage of giving the product excellent usability. This oil used in the present invention can be easily prepared from Cosmol 222 and Cosmol 43 provided by Nissin oillio in 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 it is less than 0.5% by weight, it is difficult to see the whitening effect due to the poor solubility of the water-soluble whitening material. If the amount is more than 30% by weight, the powder is entangled due to the excessive amount of oil.

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 for improving skin pigmentation. In addition, the cosmetic composition may be a cosmetic composition to improve skin dullness.

In one embodiment of the present invention, the cosmetic composition may be selected from the group consisting of two-way cake, fact, face powder, eye shadow, blusher, skin cover, but is not limited thereto.
