Description

Water in silicon type make-up cosmetic composition with whitening function}

The present invention relates to a water-in-silicone (WATER IN SILICON) type makeup cosmetic composition having a whitening function. More specifically, the present invention relates to a makeup cosmetic composition of the W / S type having a high whitening effect and excellent skin moisturizing effect and stability by containing a large amount of arbutin and vitamin C magnesium phosphate as a whitening material.

When the skin is exposed to ultraviolet rays, melanocytes, which are natural UV blockers, are produced in the skin to protect the skin.These melanocytes influence the color of the human skin, and the skin color is black because there are more yellow melanoma and black species than melanoma. The frequency of skin cancer caused by a lot of white people is a well known fact. However, overdeposition of melanin causes melasma, freckles, and skin darkening. Therefore, there is a need for the development of a cosmetic containing a whitening raw material to prevent skin darkening caused by sunburn and to reduce parasitic melanocytes.

In general, in the case of disperse and emulsified makeup cosmetics, the basic product (skin, lotion, cream, essence, etc.) is used in the stage of the base makeup after consumer use. This large, whitening function had to be obtained through a separate functional skincare product. However, in the case of the conventional dispersion and emulsified products, such whitening and skin care aspects are lacking, and the products that emphasize the whitening and skin care aspects also do not show the effect by containing a small amount of some expensive raw materials of the whitening function. In other words, arbutin, placenta extract, kojic acid, lion's eractic acid, and polar's rucinol have been developed as whitening raw materials, and these whitening raw materials mainly inhibit the activity of tyrosinase to block the root cause of melanin production, but the products are extremely limited. Due to its activity, the stability of the product is lowered due to its activity, discoloration occurs, and there is a problem of causing skin pruritus and the like in direct contact with the skin. Therefore, in order to solve the above problems, W / O emulsions have been developed so that the whitening raw material can be spheroidized to avoid direct contact with the skin, while maintaining the activity and sustained release of the whitening function. However, in this case, the use of the oil is soaked and stuffy due to the fact that the trauma is oil, and secondly, the oil oozes out or the condensation of water droplets occurs compared to the general emulsion type O / W emulsion used in cosmetics. Insufficient product was limited and it was difficult to maintain the formulation of the product, especially by the inclusion of whitening raw materials, promoting the reduction of viscosity and the integration of water droplets.

Therefore, in order to solve the above problems, the present inventors have disclosed cyclomethicone (D5 and D6) and C _{30 to} W / S type emulsions using silicone oils instead of oils used in conventional W / O types while containing small-sized whitening raw materials. _By adding ₄₅ alkyldimethicone, stearyldimethicone, and hyaluronic acid, the present invention was completed by preparing a stable cosmetic composition having a whitening effect and a skin moisturizing effect, no skin pruritus, and no water consolidation or viscosity decrease.

The purpose of the present invention is to further contain the whitening effect and skin moisturizing effect by further containing hyaluronic acid as arbutin and vitamin C magnesium phosphate stabilizer as a whitening raw material, C _{30 ~ 45} alkyldimethicone as a stabilizer, stearyl dimethicone and a moisturizing agent The present invention provides a stable W / S type makeup cosmetic composition that is free of pruritus and has no water soaking or viscosity decrease.

The object of the present invention is to prepare a cosmetic composition of the conventional O / W water-in-oil type and a cosmetic composition of the W / S type of the present invention containing a whitening raw material, the skin stimulation and moisturizing effect, whitening effect and customer satisfaction After investigating each of them, the conventional cosmetic composition containing no cyclomethicone, C _30-45 alkylmethicone, stearyldimethicone, and hyaluronic acid and the present cosmetic composition further containing these components were prepared by investigating stability and viscosity change. Achieved.

The present invention comprises the steps of preparing a whitening cosmetic composition of the O / W water-in-oil-integrated type and whitening cosmetic composition of the present invention W / S type containing arbutin and vitamin C magnesium phosphate as a whitening material; Investigating the skin moisturizing power and skin irritation of the prepared conventional and the present invention cosmetic composition; Investigating the whitening effect of the conventional and the present invention cosmetic composition prepared by measuring the tyrosinase activity inhibitory effect; Investigating the customer satisfaction of the conventional and the present invention cosmetic composition prepared; The present invention also contains a cyclomethicone (D5 or D6), a C _30-45 alkyldimethicone, a stearyldimethicone, and a dispersion emulsion makeup cosmetic composition and a whitening material. D6), preparing a conventional whitening cosmetic composition containing no C _30-45 alkyldimethicone, stearyldimethicone component; Observing the change in viscosity and discoloration of the prepared dispersion-emulsion makeup cosmetic composition and the conventional whitening cosmetic composition of the present invention is composed of the step of measuring the stability respectively. In the present invention cyclomethicone D5 or D6 according to the structure of the cyclic silicone As a distinction, the former has a pentagonal structure and the latter has a hexagonal structure, and there are trade names DC345 (Dow Corning) and DC246 (Dow Corning), respectively. In the present invention, C _{30 to 45} alkyl dimethicone is a waxy substance that uses an alkyl group having _{30 to 45} carbon atoms attached to the structure of dimethicone, and vitamin C magnesium phosphate is a substance having high oxidation stability and magnesium Phosphate is a combined raw material and uses the trade name 'VC-PMG' (Nikkol). In the embodiment of the present invention, the cyclomethicone and dimethicone copolyols are used simultaneously. This is because the dimethicone copolyol, which is a highly viscous emulsifier, is dispersed in a base material called cyclomethicone to separate the dimethicone copolyol. To enhance the acidity, the brand name 'DC5225-C (Dow Corning)' was used as a raw material.

Hereinafter, the specific method of the present invention will be described in detail with reference to Examples and Experimental Examples, but the scope of the present invention is not limited to these Examples and Experimental Examples.

Experimental Example 1: Investigation of stability

The change in the stability of the dispersion prepared in Example 2, emulsion cosmetic composition 6 ~ 13 was investigated. As a method of stability investigation, the union and viscosity of the soaked particles were measured, and the sum of the soaked particles was visually measured by emulsified particles with a 200x magnification over time. Changes and discolorations over time were observed. As a result, as shown in Table 6, make-up cosmetics 12 and 13 containing no silicone waxes such as stearyl dimethicone and C _{30 to 45} alkyl dimethicone showed a marked drop in viscosity over time. Indicated the union of. Discoloration by arbutin and vitamin C magnesium phosphate was also observed. In contrast, the makeup cosmetics 6 to 10 containing stearyldimethicone and C _{30 to 45} alkyldimethicone did not have a change in viscosity and discoloration with time, and the makeup cosmetics 6, 9, 10, and 11 were soaking particles. Although the union of was not observed, the makeup cosmetics 7 and 8 which do not contain hyaluronic acid and cyclomethicone (D6) were found to have some water droplets. As hyaluronic acid and non-volatile silicone are contained, it is possible to prevent the coalescence of soaking particles, and the decrease in viscosity with time is not solved by the change of emulsifier, and must contain stearyldimethicone and C _{30 ~ 45} alkyldimethicone. Stearyl dimethicone, C _{30 ~ 45} Alkyl dimethicone was found to be able to freely adjust the viscosity by appropriate mixing control.
