Description

Cosmetic composition containing nephrite powder as an active ingredient {Cosmetic composition with nephrite powder}

The present invention relates to a cosmetic composition containing nephrite powder, and specifically, to a cosmetic composition having excellent skin keratin improvement, skin pore improvement and skin oil and moisture balance control effect.

The stratum corneum of the skin is the outermost layer in direct contact with the outside, and functions as a defense against various external physical, chemical and mechanical stimuli. Keratin (keratin) cells are dead skin cells, which are cells formed through stages of morphological and functional changes as the basal cells that continuously proliferate in the hypodermis move to the stratum corneum.

After a certain period of time, the old keratinocytes are removed from the skin, and the epidermal differentiation and keratinization process in which new keratinocytes replace their function is repeated. In this keratinization process, keratinocytes produce natural interstitial factors and intercellular lipids such as ceramides, cholesterol and fatty acids, and serve as a skin barrier that blocks the outside and the body.

However, depending on the degree of aging and skin damage, the skin loses elasticity due to the change in the extracellular matrix component, which reduces the thickness of the epidermis, dermis and subcutaneous tissue, reduces the skin moisture content, and gives the skin elasticity. Wrinkles are formed, and the separation of the stratum corneum is later than normal, the stratum corneum thickens and the skin loses vitality. When the thickened stratum corneum is artificially removed from the outside, the living cells under the stratum corneum are activated or regenerated to soften the skin texture, and have effects such as wrinkle reduction, acne occurrence suppression and treatment. Accordingly, studies have been conducted to remove dead dead skin cells and soften the skin within a range that does not cause irritation.

On the other hand, the sebaceous gland, an appendage of the skin, secretes sebum into the outermost layer of the skin through the pores. Sebum has the effect of preventing the evaporation of moisture in the stratum corneum and giving the skin a shine, but if the secretion of sebum is excessive, the skin becomes shiny and causes acne due to inflammation and folliculitis caused by bacterial infection. On the other hand, if sebum secretion is low, the skin becomes dry, which causes diseases such as psoriasis. Therefore, sebum control, that is, regulation of oil and moisture balance, is important for skin care.

Accordingly, the present invention is intended to develop and provide a cosmetic composition having excellent skin keratin improvement and skin oil and moisture balance control effect.

[Experimental Example 1: Confirmation of sebum adsorption effect of nephrite powder]

In this experimental example, we tried to compare the sebum adsorption effect of white clay, illite, pulverite (rockstone) and purgatory powder, which are widely used as raw materials to give sebum control efficacy when developing cosmetic formulations. Soybean oil was used as the substance.

The nephrite powder and the clay, mica, and mackban stone were weighed in a conical tube of 0.5 g each and then weighed by adding 5 ml of soybean oil. The vortex agitation was repeated 3 times for 1 minute at 5 minute intervals, followed by centrifugation at 3,000 rpm for 4 minutes to remove the supernatant and measure the weight. The sebum absorption rate was calculated as follows and the results are shown in FIG. 1.

Absorption rate (%) = [(Measured value after soybean oil absorption-measured value before soybean oil absorption)/measured value before soybean oil absorption] × 100

As shown in Figure 1, as a result of evaluating the sebum adsorption efficacy of the raw material itself, it was confirmed that the sebum adsorption effect of purgatory powder is superior to that of clay, mica, and mackbanseok.

[Example 1: Preparation of cosmetic composition containing nephrite powder]

In this example, a cleanser composition containing purgatory powder was intended. All the raw materials of Example 1 shown in Table 1 below were completely dissolved at 80° C., and then stirred with a homogenizer at 1500 rpm for 5 minutes. Subsequently, it was put into a jar-shaped container and cooled to 25°C to completely solidify to prepare a cosmetic composition. Comparative Examples 1 to 4 were prepared in the same manner as in Example 1 according to the composition of Table 1 below.

[Experimental Example 2: Evaluation of keratin improvement efficacy of cosmetic composition containing nephrite powder]

In this experimental example, it was intended to confirm the effect of improving the keratin of the cosmetic composition containing the purgatory powder prepared in Example 1. After applying the cosmetic composition to the skin with keratin and washing it, the skin condition before and after washing was photographed and the efficacy of the keratin was compared and evaluated. Skin condition was photographed using KC Technology's Hair Polarzer_PL5-471 and Callegari S.r.l's Soft Pluss.

3 g of the cosmetic composition of Example 1 and Comparative Examples 1 to 4 were applied to dry skin having a similar degree of keratin, rubbed with the same force for 1 minute, and then the remaining cosmetic composition was washed with water. It is shown in Figure 2 by measuring the keratinous state of the skin in a state where the water is completely dried after towel drying. In the case of the Keratin measuring device of Soft Pluss, the keratinous part of the skin surface appears white, which means that the more keratinized areas are, the more keratin.

As shown in FIG. 2, in the case of Comparative Example 1 and Comparative Example 2, which were not added, the effect of improving keratin before and after washing was not noticeable, but in Example 1, the effect of improving keratin before and after washing was excellent compared to Comparative Example, and Soft Even when comparing the results of Keratin measurement of Pluss, it can be seen that Example 1 effectively improved keratin compared to Comparative Example.

As shown in Table 2, it was confirmed that the skin oil content of Example 1 immediately after use of the cosmetic composition was reduced.

(2) Measurement of skin moisture content

The experiment was conducted in the same manner as the method for measuring the skin oil content, and the skin moisture content was measured using Epsilon before and immediately after use. The measurement results are shown in Table 3 and FIG. 3 below. The unit of measured skin moisture content is A.U.(Arbitrary Unit), and the analysis value and the degree of skin moisturizing power are proportional.

Skin moisture content change time Mean ± standard deviation (A.U) Improvement rate ^a (%) Significant probability ^b (p value) Before use 20.758±7.780 - - Immediately after use 26.240±6.940 34.331.177 0.000* Improvement rate ^a (%) = [(measured value after product use-measured value before product use)/measured value before product use] x 100
