Description

Solid composition for personal care containing a natural surfactant, body wash, face wash, and shampoo containing the same

[0001] The present invention relates to a solid composition for personal care comprising a natural surfactant, and to a body wash, face wash, and shampoo comprising the same. More specifically, the invention relates to a body wash, face wash, and shampoo comprising an eco-friendly solid composition for personal care that includes a natural surfactant made of vegetable oil, which continuously forms rich foam, has good cleaning power, and is easy to carry.

[0002]

[0003] The skin is broadly divided into three layers—the epidermis, dermis, and subcutaneous fat tissue—in order from the outside in, and functions to protect the human body from physical and chemical stimuli from the external environment. Among these, the epidermis is divided from the outside in the order of the stratum corneum, stratum granulosum, stratum spinosum, and stratum basale; the cells of the stratum corneum act like bricks, and the intercellular lipids between the keratinocytes act like mortar, forming the skin barrier. The stratum corneum of the epidermis contains approximately 10 to 20 percent water and, as the outermost layer of the body, inhibits water evaporation from the outside while blocking the excessive penetration of external substances. The surface of this stratum corneum is covered by a thin natural protective film formed from sebum from sebaceous glands and sweat from sweat glands, which prevents water evaporation.

[0004] Furthermore, lipids between keratinocytes in the stratum corneum are tightly bound to the cells in the form of a lamellar liquid crystal structure. Skin lipid components consisting of 50% ceramide, 25% cholesterol, and 15% free fatty acids perform the skin's barrier function. Ceramide plays a crucial role in the formation, maintenance, and repair of the skin barrier; imbalances in its content and composition ratio lead to a decline in barrier function and the exacerbation of various skin conditions. While cholesterol present in blood vessels poses a danger to the body, the cholesterol constituting skin lipids is a highly effective component for performing the role of the skin barrier; it possesses strong interparticle cohesion and is produced through self-synthesis within the epidermis. Free fatty acids play an important role in maintaining the pH of the stratum corneum at a slightly acidic level of approximately 0.5 to 5.5. While they are produced within the epidermis itself, free fatty acids generated in other organs are also absorbed by keratinocytes. These free fatty acids play a vital role in maintaining the homeostasis of the barrier function.

[0005] Therefore, because strong body washes or facial cleansers can denature the intercellular lipids of the stratum corneum and impair the function of the stratum corneum, which is supposed to protect the skin, natural plant-based cosmetic ingredients that can maintain skin homeostasis are being studied.

[0006] Based on the above background technology, the inventors have completed the present invention relating to a body wash, face wash, and shampoo comprising an eco-friendly solid composition for personal care that includes a natural surfactant made of vegetable oil, which continuously forms a rich lather, has good cleaning power, and is easy to carry.

[0186] <Experimental Example 1> Scalp barrier improvement effect according to solid shampoo

[0187] To evaluate the scalp barrier improvement effect of the solid shampoo prepared as in Example 3 above, 20 adults aged 30 to 60 were instructed to use the solid shampoo at least once a day for two weeks. Transepidermal Water Loss (TEWL) was measured using a Tewemeter™ 300 to assess the scalp condition before and after product use. The Tewemeter measures the change in concentration of water evaporation indirectly from the skin using two pairs of sensors (temperature and relative humidity) located inside a cylindrical probe. A higher measurement value indicates greater water loss due to damage to the stratum corneum, while a decrease in the measurement value indicates an improvement in the scalp barrier. The unit of measurement is g / m²2 It is h.

[0188] As shown in Table 1 below, it was confirmed that the transepidermal water loss of the scalp decreased after 2 weeks of use of the solid shampoo by the subjects compared to before use, which showed a statistically significant difference (p<0.05). In addition, a comparative analysis of the average values ​​of transepidermal water loss before and after 2 weeks of use of the solid shampoo by the subjects revealed that the scalp barrier function was improved by 29% due to the solid shampoo.

[0192] <Experiment Example 2> Scalp Moisturizing Improvement Effect According to Solid Shampoo

[0193] To evaluate the scalp moisturizing improvement effect of the solid shampoo prepared as in Example 3 above, 20 adults aged 30 to 60 years were asked to use the solid shampoo at least once a day for 2 weeks, and the moisture content was measured using a Corneometer. The measurement using the Corneometer measures the electrostatic capacitance of the skin through a probe. Since skin moisture content and electrostatic capacitance are proportional to each other, the measured value increases as the moisture content increases, and it was evaluated that scalp moisturization has improved. The measurement unit is the dimensionless unit AU (Arbitrary Unit).

[0194] As shown in Table 2 below, it was confirmed that the moisture content of the subjects' scalps increased after using the solid shampoo for 2 weeks compared to before use, which showed a statistically significant difference (p<0.05).

[0198] <Experiment Example 3> Effect of Solid Shampoo on Improving Scalp Itching

[0199] To evaluate the scalp itching improvement effect of the solid shampoo prepared as in Example 3 above, a Visual Analogue Scale (VAS) was administered to 20 adults aged 30 to 60 years who used the solid shampoo at least once a day for two weeks. The Visual Analogue Scale (VAS) measured the degree of itching through each subject's subjective self-assessment of itching, and the changes in measured values ​​were compared and evaluated before product use (Week 0) and after two weeks of use. The assessment was conducted using the Visual Analogue Scale (VAS), a 10-point scale itching evaluation tool, and itching was evaluated as improved as the score for the degree of itching decreased. The evaluation criteria for the Visual Analogue Scale are as shown in Table 3 below.

[0207] <Experimental Example 4> Scalp Exfoliation Improvement Effect According to Solid Shampoo

[0208] To evaluate the scalp exfoliation improvement effect of the solid shampoo prepared as in Example 3 above, 20 adults aged 30 to 60 years were subjected to one use of the solid shampoo, and the scalp exfoliation improvement effect was evaluated using image analysis with Visioscan® VC20 plus. The four variables of the measurements derived from the Visioscan® VC20 plus are SEr (Roughness), SEsc (Scaliness), SEsm (Smoothness), and SEw (Wrinkles), and among them, the SEsc (Scaliness) value, which represents the amount of skin exfoliation, is used. A decrease in the SEsc (Scaliness) value indicates a decrease in the amount of scalp exfoliation.

[0209] As shown in Figure 3 and Table 5 below, it was confirmed that the amount of scalp keratin decreased after one use of the solid shampoo compared to before use, indicating that scalp keratin is significantly removed with just a single use. These results showed a statistically significant difference (p<0.05). In addition, a comparative analysis of the average scalp keratin amount before and after one use of the solid shampoo by the subjects revealed that the improvement in scalp keratin by the solid shampoo was 87.5%.

The measurement of the Sebumeter involves absorbing oil using a special translucent lipid-absorbing tape and measuring the transmittance of light passing through the tape after it becomes transparent. The transmittance of light passing through the transparent tape represents the amount of oil, and it was evaluated that scalp sebum (oil) improved as the measured value decreased.

[0215] As shown in Table 6 below, it was confirmed that the amount of sebum on the scalp of the subjects decreased significantly after one use of the solid shampoo compared to before use. These results showed a statistically significant difference (p<0.05). In addition, a comparative analysis of the average values ​​of scalp sebum before and after one use of the solid shampoo of the subjects revealed that the improvement in oiliness of the scalp by the solid shampoo was 85.5%.

[0219] <Experiment Example 6> Effect of Solid Shampoo on Ultrafine Dust Cleansing Power on the Scalp

[0220] To evaluate the effect of improving the cleansing power of ultrafine dust on the scalp by the solid shampoo prepared as in Example 3 above, a study was conducted on 20 adults aged 30 to 60. Carbon black, which is a mimic of ultrafine dust with a size of 0.03 to 0.20 μm, was applied to the scalp and hair, and the solid shampoo was used once. Images were captured using a high-resolution imaging device, the KONG Camera (Video Micro Scope, Bomtech), and analyzed using an image program. For the analysis, images were captured using the high-resolution imaging device before using the solid shampoo, after applying the mimic, and after applying the mimic and using the solid shampoo once. The intensity values ​​were analyzed using the image program, and the changes in intensity values ​​before product use, after application of the mimic, and after one cleansing were compared and evaluated. It was assessed that the ultrafine dust mimic was cleansed as the intensity value after cleansing increased.

[0221] As shown in Figure 4 and Table 7 below, the lightness values ​​of the subjects' scalps and hair increased after the application of the ultrafine dust mimic and one use of the solid shampoo compared to before the application of the ultrafine dust mimic and the solid shampoo, and the lightness values ​​after the application of the ultrafine dust mimic and one use of the solid shampoo were similar to the lightness values ​​before the application of the ultrafine dust mimic. This indicates that the ultrafine dust mimic is almost completely removed even with just one use of the solid shampoo, suggesting that the solid shampoo exhibits excellent scalp cleansing power. Furthermore, a comparative analysis of the average lightness values ​​before and after one use of the solid shampoo following the application of the ultrafine dust mimic revealed that the cleansing power of the solid shampoo was 98%.
