The customized cosmetics preparation management qualification system was implemented in March 2020, and it served to create jobs by developing professionals and vitalizing the cosmetics business. However, various problems such as high examination fees, suitability of questions, and utilization in industries are emerging. This paper attempts to prevent disputes that the system can cause and suggest ways to improve it by researching customized cosmetics, the industry status, and comparing foreign cosmetics laws. There is a kind of opinion that laws should be eased for this industry and the other opinion that expertise is necessary in this field because of safety. The system now has adverse effects due to a failure to adjust the difficulty of the exam. Cosmetics are not prescription-based, so they are routinely used. However, some toxic ingredients can cause side effects if they do not conform with certain standards. Also, it is difficult for a case to lead to lawsuits because most consumer damages related to cosmetics are individual. In addition, as e-commerce develops, there is a growing possibility of seeing more consumer damages. If safety and distribution issues, which experts are concerned about, escalate, the private dispute settlement system (among the ADR systems) should be activated as a resolution method.

Bamboo is a plant belonging to the Gramineae family, and can be used as valuable bioresources for many industrial applications. Bamboo has some useful properties and having a lot of beneficial uses such as a bamboo ware, agriculture material, building construction material, pulpwood, etc. Bamboo stem has a large amount of active ingredients that those of bamboo leaves. The stem of bamboo can be processed into various biomaterials including cellulose and lignin, and sometimes uses as foods, cosmetics and medicines using stem extracts with polyphenol compounds. For cosmetic applications of bamboo stems, especially, the constituents of bamboo stem are suitable for inner beauty (cosmetic food) products showing antioxidant and UV-protecting activities. This review summaries the recent literature data and discusses the versatile uses of bamboo stem and its extracts mainly for cosmetic application.

BMB-CF has been constituted of purified fractions of Scutellaria baicalensis, which has medicinal effect such as anti-microbial. anti-inflammation. fever remedy. anti-oxidation. and anti-aging effect etc.. It has been used in traditional medicine formula from long time ago in the east Asia. It is constituted of the active flavone ingredients such as baicalin. baicalein. DTF(Di-methyl Tetra -hydroxy Flavone), wogonin. wogonoside. $\beta$- Sitosterol. etc.. General purified fractions of Scutellaria baicalensis has the high portion of the baicalin which has the problem of narrow antimicrobial spectrum and compatibility against cosmetic formula. Now. we has been develop the new purificaton process of Scutellaria baicalensis that has the high rate of DTF content, which is improved in antimicrobial activity and cosmetics compatibility. So. we have assure that it is the potent preservative against various cosmetic formula.

A tyrosinase inhibitor, Lonjapoin, was isolated from the ethanolic extracts of Flos Lonicera by activity-guided fractionation. Lonjapoin ($IC_{50}$/; 2.07 $\mu\textrm{g}$/mL) was found to be potentially as effective inhibitor of production of melamin. Flos Lonicera (Jinyinhua) is the dry flower buds of Lonicera japonica. Thunb. It is used as an antibacterial and antiphlogistic agent in the treatment of abscess, laryngeal catarrh, erysipelas, dysentery, cold and fever. In our continuing search for natural source as cosmetic ingredients from Chinese medicinal herbs and found the extracts of Flos Lonicera showed the significant tyrosinase inhibition activity. In this study the active constituent of Lonicera japonica. obtained with the process of tyrosinase activity assay and column chromatography.

To investigate the effect of peanut sprout extract on skin care, we measured anti-oxidant activity and whitening action. As a result of measuring DPPH radical scavenging activity to examine independent anti-oxidation of peanut sprout extract, there was strongly scavenging activity. Fluorescent material DCF-DA was used to measure hydrogen peroxide created in RAW 264.7 cells, and all concentration dependently decreased ROS production. As a result of measuring nitric oxide to examine anti-inflammation of peanut sprout extract, there was strongly inhibited nitric oxide production in RAW 264.7 cells. Tyrosinase activation was found to inhibited dose-dependant. Melanin production was also prevented dose-dependant. Therefore, it is expected to be used effectively in development of functional cosmetic materials.

During cosmetic treatments, SURFACTANTS penetrate into KERATINOUS TISSUES (hair, skin and nails). Whereas some of these surfactant molecules migrate to the vital tissues, a considerable fraction remains bound to the keratin. The extent of binding depends both on the nature of the head group and the length of the hydrophobic tail of the detergent molecules. In addition to entering the amorphous region of the keratin, some of the detergents also penetrate into the crystalline microfibrils and change their structures affecting their tensile properties. Owing to an uneven distribution of detergent molecules in the tissues, an anisotropy of the elastic moduli will occur, resulting in considerable internal stresses which, in rum, might lead to a deterioration of hair, skin and nails. The chemical behavior of keratins is also influenced by the presence of absorbed detergent in their structures. Depending on the detergents and the conditions, these effects can be either protective or detrimental. The deposition of detergent molecules into keratin can be enhanced or diminished by the inclusion of appropriate ingredients into the product formulae.

Chemists must take into consideration more factors to formulate with inorganic sunscreens than many other active ingredients including organic sunscreens. Because the UV radiation attenuation grade particles of Titanium Dioxide and Zinc Oxide are in the nanometer range, the state of their dispersion in the product film on the skin governs their efficacy and aesthetics.(omitted)

The purpose of this study is to offer basic data on cosmetics by investigating college women's purchasing and use behaviors regarding cosmetics according to their experience with side effects. A questionnaire was administered to 351 college women in the Seoul and Kyoung-in areas. The data were analyzed with SPSS Statistics V22.0 using frequency, ${\chi}^2$-test, and t-test. The results are as follows. First, 72.6% of surveyed women reported experiencing side effects from cosmetics. The largest side effects were acne and boils, and the primary ways of coping with these side effects were discontinuing use and using other products. Second, the group that experienced cosmetics' side effects used brands that were more expensive and eco-friendly than the group without side effects. Third, the group that experienced side effects continued to use the product more than the group without side effects. The primary reason for continued use was efficacy, and the reasons for discontinued use were efficacy and curiosity. Fourth, the side-effects group proactively identified cosmetics ingredients more than the non-side-effects group. Specifically, they checked the major components, the function, and for any hazardous ingredients. Fifth and finally, 98.3% of survey respondents purchased and used functional cosmetics. The group that had experience with side effects used more functional cosmetics than the group without side effects.

오미자 씨 오일의 화장품 소재로서 가능성을 평가하기 위해 GC와 GC/MSD를 사용하여 안정성 평가 및 성분 분석을 실시하였다. 그 결과 주요성분은 팔미틱산과 올레익산으로 나타났다. 오미자 씨 오일은 열에 의한 성분변화가 없고, 소재 자체의 안정성이 뛰어난 것으로 나타났다. 또한, DPPH(1,1-Diphenyl-2-picrylhydrazyl) 라디칼 소거능 실험을 통하여 항산화 효능을 측정한 결과 오미자 씨 오일이 마카다미아 오일과 올리브 오일에 비하여 높은 항산화 효능을 나타내었다. 콜라겐 합성능 또한 뛰어난 것으로 평가되었다. 따라서, 오미자 씨 오일은 화장품 소재용으로 유용하게 활용될 수 있는 가능성을 가진 것으로 평가되었다.

탈모 방지의 목적으로 사용되는 양모제는 현재 우리나라에서 의약외품이며 약사법으로 관리되고 있다. 최근 탈모에 대한 사회적 관심이 증가하면서 양모제에 대한 수요도 증가하고 있는 실정이지만 양모제는 생약추출물, 비타민류, 보존제 등 다양한 종류의 성분이 혼합되어 있어 분석이 쉽지 않다. 본 연구에서는 양모제의 주성분으로 많이 쓰이는 니코틴산아미드, 덱스판테놀, 살리실산, 초산토코페롤, 니코틴산벤질에 대한 동시분석법을 확립하고자 하였다. 시판 중인 양모제를 구입하여 $C_{18}$ 컬럼, 아세토니트릴과 인산염완충액을 용매로 사용하여 HPLC로 분석하였다. 검출은 자외부 흡광광도계를 이용하여 220, 270, 300 nm 파장에서 분석하였으며, $12.5{\sim}800\;{\mu}g/mL$ 농도범위에서 검량선을 작성하였다. 회수율은 액상기제의 경우 97.3 ~ 103.5 % (상대표준편차 0.9 ~ 2.8 %), 샴푸기제의 경우 101.9 ~ 115.9 % (상대표준편차 0.7 ~ 7.7 %)로 양호한 결과를 나타냈다. 시판중인 검체의 함량 시험결과 기준에 적합하였으며, 본 분석법을 이용하여 품질관리 및 추후 양모제 개발에 유용하게 활용함으로써 우수한 품질의 양모제 유통에 크게 기여할 것으로 기대된다.
