Description

Technical Field [0001] The present invention relates to a cosmetic composition for moisturizing cosmetic composition containing Saururus chinensis fermented extract,

The present invention relates to a cosmetic composition for moisturizing which can improve skin dryness, and more specifically relates to a cosmetic composition for moisturizing moisturizing cosmetic composition containing a Saururus chinense fermented extract and a method for producing the same.

The skin is divided into three layers of epidermis, dermis and subcutaneous adipose tissue in order from the outside, and functions to protect the human body from physical and chemical stimulation of the external environment. Especially, skin carries about 65 ~ 70% of the human body's moisture, that is, various physiologically active substances necessary for the human body, and helps to keep the skin soft and moist, It plays a role. In addition, the epidermis is divided into stratum corneum, granular layer, superficial layer, and basal layer in the order from the outside. Cells of the stratum corneum act like bricks and intercellular lipids between keratinocytes function as mortar to constitute skin barrier (J. Invest. Dermatol. 80 (Suppl.), 44-49, 1983). Recently, it has been newly found that not only the water content in the stratum corneum is increased but also the differentiation process developed from the keratinocytes in the basal layer to the keratinocytes in the outermost stratum corneum can be performed normally to function as a skin moisture retention barrier lost. In other words, physiological skin drying results in prolonged removal time of the stratum corneum, lowering lipid synthesis ability of epidermal cells, and decreasing the amount of moisturizing factors and lipids in the stratum corneum of the skin. Therefore, by promoting differentiation of keratinocytes, . Therefore, it can be expected that an excellent skin moisturizing effect can be obtained by using a water retaining material in the stratum corneum and a substance promoting keratinization promotion together.

In recent years, there has been remarkable use of herbal medicines in the field of cosmetics, however, herbal medicinal compositions using herbal medicinal extracts extracted by ordinary methods have not only a desired skin moisturizing effect but also have a long practical time to obtain such extracts. I did.

On the other hand, the fermentation broth extract does not use any other solvent, so the sugar content in the herbal medicine is changed into alcohol, and after fermentation and aging process, the extraction rate of active ingredient such as flavonoid, vitamin C, vitamin P, amino acid and catechin contained in the herbal medicine And thus, a much better skin moisturizing effect can be obtained.

Therefore, it is necessary to develop a new skin moisturizer which is stable without skin irritation through the extract of the herbal medicine fermentation broth, and maximizes the skin moisturizing effect.

Experimental Example - Moisturizing Effect Experiment of Cosmetic Composition

In order to evaluate the moisturizing power of the cosmetic composition prepared according to the present invention, the skin holding ability and moisture evaporation amount of the skin coated with the cosmetic were measured as follows.

(1) Measurement of water holding ability of cosmetic composition

A predetermined amount (0.03 g / 16 cm ² ) of cosmetic prepared in a constant temperature and humidity room at 22 ° C. and a relative humidity of 45% was applied to the inside of each of the forty subjects and the moisture of the skin before application, one hour after application and two hours after application And the normal skin without any treatment was used as a comparative example. The measuring device used a moisture content measuring device (corneometer CM825, Conrage + Khazaka, Germany) measuring the capacitance of the skin according to the moisture content of the skin and measuring the moisture content. The results are shown in Table 1 below.

(2) Measurement of moisture evaporation amount of cosmetic composition

The skin barrier was weakened by performing tape stripping on the upper arm portion of the arm. Then, the cosmetic material was applied to the subject in the same manner as in the measurement of the moisture holding ability, and then the skin was cleaned with a moisture evaporator (Tewameter TM300, Conrage + Germany federal agency) to measure the evaporation of water five times at intervals of 1 minute every 12 hours. The results are shown in Table 1 below.

Example Comparative Example Moisture holding ability Before application 100.0 100.0 After 1 hour 112.3 89.4 After 2 hours 136.1 50.6 Moisture evaporation After 0 hours 100.0 100.0 After 12 hours 61.7 95.7 After 24 hours 49.9 91.5 After 36 hours 35.8 84.2 After 48 hours 20.1 75.1

As shown in the above experimental results, it can be seen that the cosmetic composition of the present invention has a higher electric conductivity of the skin and a lower moisture loss than the comparative example, and thus has excellent skin moisturizing effect.

The features, structures, effects, and the like illustrated in the above-described embodiments can be combined and modified in other embodiments by those skilled in the art to which the embodiments belong. Therefore, it should be understood that the present invention is not limited to these combinations and modifications.
