Description

A cosmetic composition of jelly type "

The present invention relates to a jelly-type cosmetic composition, and more particularly to a jelly-type cosmetic composition which comprises a skin cooling effect, a whitening effect, a pore-shrinking effect and a moisturizing and holding power including a polyvinyl alcohol, sodium borate and glycerin in a specific ratio, The present invention relates to a cosmetic composition of the jelly or flubber type having excellent pore-improving effect.

Due to the recent improvement in the quality of life as a result of economic development, cosmetics are becoming a necessity for life, in accordance with the needs of modern people for aesthetic pursuit. Therefore, cosmetics are becoming more and more functional in protecting the skin, and functioning to prevent and improve the physiological changes of skin caused by aging. Especially Asian women have a high preference for white and clear skin, and their desire for improvement of skin color and pigmentation is considerably high.

Human skin color is determined by the ratio of several natural factors and is determined by melanin and carotenoids, oxidized hemoglobin, reduced hemoglobin, bilirubin and the like. Melanin, the major determinant of skin complexion, is overlaid on the epidermis and dermis by increased melanocyte activity and increased activity of melanogenic enzymes, and this increased production and accumulation of melanin is the most common phenomenon of skin pigmentation-related diseases . The lipid of the stratum corneum is present in several layers between keratinocytes, and the constituents are ceramide, free fatty acid cholesterol and cholesterol sulfate.

If the secretion of sebum is excessive, the skin will shine, the skin will become inflamed, the acne will be induced, and folliculitis caused by the bacterial infection will occur. On the other hand, when the lipid content of the skin surface is reduced, the skin becomes dry and the skin disease occurs. The pores that secrete sebum are entirely in the skin of the face, especially the nose and the ball area can be distinguished by the naked eye. There are individual differences in the appearance of pores due to factors such as sex, genetic, aging, chronic ultraviolet exposure, acne and endogenous and extrinsic factors. The characteristics of these skin aging are accumulation of minute changes over a long period of time. There is an increasing demand for products with potent or protective efficacy.

In addition, there is an increasing demand for convenient use of various stages of beauty stage, while satisfying various skin functions in daily life.

However, conventionally, since each cosmetic material such as a skin toner, an emulsion, a serum and a cream is repeatedly used step by step, the individual efficacy provided by each cosmetic material can be taken by one or two steps in stages, There is a problem that it is not satisfactory, it is cumbersome to use, and it takes much time to obtain sufficient efficacy.

The pack is one of the cosmetics that has been used for a long time and is used not only for the face but also for the part of neck, shoulder, arms, legs and whole body.

The pack is moisturized and softened by the water coming from the subcutaneous layer by the closure effect of the moisture, the moisturizing agent, the emollient agent and the applied pack. In addition, since the adsorbing action of the pack and the removal of the surface of the skin at the time of peeling off the skin are eliminated, there is an excellent cleaning action. The pack gives proper tension to the skin during the drying process of the encapsulant and the powder, and temporarily increases the skin temperature after drying to smooth the blood circulation.

Packs are largely divided into wash-off type, application type, and peel-off type. The product type and characteristics of each pack are as follows: First, the cream type product is a wash type pack. O / W type emulsion type cream is used. It is used to lower the hardness and to give a sufficient moist feeling after use Therefore, the amount of moisturizer is large. It is difficult to mix powder containing clay minerals with water + ethanol + moisturizing agent water, remove it after drying, and most of it is washed with water.

The application type of the nonwoven fabric gel in the application type pack depends on the property of the gel, but is noted as a new type pack. It is easy to use and has a high combination effect with other basic cosmetics. Non-woven fabric impregnated product type is a non-woven fabric impregnated with lotion and essence.

The peel-off type has a jelly phase, which is transparent or semitransparent jelly, and forms a transparent film after application and drying. After peeling off the film, it shows a moisturizing and softening effect and a cleaning effect. Since the product form on the paste can form a comparatively large amount of opaque paste, powder, oil component, and moisturizer, it gives a sufficient moist feeling after the film formation and peeling in drying. Powdered product forms are uniformly melted and applied with water or the like when using powdered base. The evaporation latent heat of water is refreshing, crisp, strong and strong for summer.

Accordingly, the technical problem to be solved by the present invention is to provide a cosmetic composition which is easy to use and which allows a sufficient amount of cosmetic material to be rapidly penetrated into the skin to provide skin cooling effect, whitening effect, pore shrinkage effect and moisture retention ability as well as wastes removal effect, To an excellent cosmetic composition.

<Test Example 4> Measurement of whitening effect

When tyrosinase becomes active due to ultraviolet rays or the surrounding environment and internal hormone, tyrosine or dioxyphenylalanine (DOPA) is converted to melanin by auto oxidation reaction through the pathway of dopachrome do. In this experiment, the degree of inhibition of melanin pigmentation was measured by measuring the production of dopachrome which is an intermediary step material by tyrosinase.

Tyrosinase was isolated and purified from mushrooms and purchased from Sigma. 50 μl of a sample was added to a 96-well plate by serial dilution, and then 50 μl of a 2400 units / ml tyrosinase solution and 100 μl of a 0.3 mg / ml L-tyrosine solution were added in this order. In the control group, the same amount of the solvent in which the sample was dissolved was added instead of the sample. After incubation at 37 ° C for 10 minutes, the absorbance was measured at 475 nm using an ELISA reader. The inhibition rate of tyrosinase activity of each sample liquid was calculated according to the following equation (1), and the experimental results are shown in Table 4 below.

A: Absorbance of the control group

B: blank absorbance of the control group

C: Absorbance of the sample
