The propensity to purchase babies' cosmetics is investigated and analysed for this research. The synopsis of this research paper is as follows. The first, the $68\%$ of all respondents do not how a manufacturer or brand name in the reality of variously emerging domestic and import cosmetics for babies. The second, in case of a child haying a fair, sensitive skin or atopy (atopic dermatitis), the respondents are careful in choosing babies cosmetics but in case of a child having a normal skin the older a child grows from a stage of a new-born, a baby and an infant to a primary-school child, the older its mother is, the more respondents use adults' cosmetics in common rather than use cosmetics only for babies. $7.6\%$ of respondents do not use babies' cosmetirs at ail. Especially, in using bathing goods such as a shampoo or a body cleanser, they frequently use adults' cosmetics in common. The third, the qualify is taken into the utmost consideration in purchasing babies' cosmetics. The Quality of imports is trusted and preferred better than that of domestic goods. The cost of purchasing babies cosmetics is less than 10,000 Won. consumers recognize that the price or cosmetics is rather high. The last, the improvement or babies cosmetics is 'the safety of goods', answered by $56.5\%$ of respondents. The respondents are generally not satisfied with babies' cosmetics. So, a baby's skin is threatened by a newly-built house syndrome, the increase of atopic dermatitis, etc., caused by an environmental pollutions, a change of diet and a change of residential life. Under these actual conditions, babies' cosmetics which can protect a delicate and sensitive skin of a baby should be developed immediately. Consumers should have a correct choice with precise recognition and information on a baby's skin and cosmetics and continually use the efficacious and excellent babies' cosmetics to prevent a baby from a skin irritation, and need to show a keen interest in a healthy skin of a baby.

화장품 사용 시 소비자가 가장 중요하게 느끼는 요인은 효과와 촉감이라고 볼 수 있다. 특히 반복적인 사용을 위해서 쾌적한 촉감은 필수 조건이다. 그런데, 촉감은 사용하는 사람 자신의 감각에 의존하는 것이므로, 이러한 화장품의 촉감을 포함하는 성능을 평가하기 위해서 사람에 의한 최종평가는 필수적인 단계이다. 따라서, 여러 특성의 강도를 측정하는 분석형 관능평가와 소비자의 선호도를 조사하는 기호형 관능평가의 필요성이 요구되며, 두 결과를 종합적으로 고려하는 것이 바람직할 것이다. 우리는 훈련된 전문패널에 의해 다양한 자외선차단 크림과 로션들에 대한 분석형 관능평가를 실시하였다. 그 결과, 자외선차단 제품의 관능속성 평가의 주요인은 잔여감 요인과 발림성 요인으로 나타났으며, 이 결과에 따라 제품들을 2차원 공간 상에 위치하였다. 이 중 몇 제품을 선택하여 20대 후반 여성소비자를 대상으로 기호형 관능평가를 실시하였다. 평상시 실제 화장단계에서 인지되는 자외선차단제품에 대한 용어들은 촉촉함 및 도포균일성 요인/흡수속도 요인의 두가지 요인으로 분류되었다. 이상적인 자외선차단제품의 사용감은 너무 촉촉하지도 매트하지도 않으면서, 흡수속도는 빠르고 화장밀림이나 번들거림이 적은 사용감을 나타내는 특성쪽으로 나타났다.

The purpose of this study is to analyze whether the cosmetic interest of middle school female students(n=126) is related to purchase satisfaction by using purchase behavior and informatization level as control variables. Based on the research model, three hypotheses were set and statistical tests were conducted. The results of this study are as follows. First, middle school female students used cosmetics from elementary school and cosmetics education was requested from elementary school. Therefore proper early education on cosmetic use is needed. Second, the degree of interest and purchasing behavior of cosmetics was positively correlated with the purchase satisfaction of cosmetics. Third, the purchasing behavior of cosmetics was found to have a more effect on purchase satisfaction than the cosmetics interest. Especially, 'cosmetics purchase behavior' had a moderating effect on purchase satisfaction. Fourth, there was no difference in the average among the grades about cosmetics category(cosmetic interest, purchase behavior, informatization level, purchase satisfaction). This study needs to pay more attention to cosmetics purchasing behavior, which has the greatest effect on the satisfaction of cosmetics purchasing among middle school girls, and suggests that further studies will be continued to expand the range and ages in the future.

This paper proposes an application which applied in managements of cosmetics and finds applications related with expiration date among applications. In this paper, the application is implemented to improve safety and stability of cosmetics based on android platform. In general, it is hard to use to have all knowledge in many types of cosmetics. Because of that each item have different date to buy and use, it is necessary to manage them efficiently. This paper is designed and implemented the application for management of expiration date to use cosmetics. It helps to use cosmetics safely and serve good information from cosmetics companies connected with this application.

The cosmetic fine powders were mixed with variation of mixing time(5) in the mixers (ribbon mixer, powder mixer, micropulverizer and fine impact mill). The powders were nixed with small amount of ferric oxide. as tracer. The mixed powders ere measured the particle size distribution, specific surface area and surface color with mixing time (s). The color variation, particle size distribution and specific surface area of the mixed powder exist a relationship with mining time(s) that can be expressed as mathematical equations to show the degree of the mixing of the powder mixture. The linear velocity of the impellar tip is the main factor contributing to he mixing efficiency of the mixers un this study. According to the linear velocity, he mixers used are devieded as convection mixing (ribbon mixer), sclera mixing powder mixer) and diffusion mixing (micropulverizer/fine impact mill).

Oxidation/reduction titrations are important quantitative procedures for many chemicals. Several widely used analytical methods for cosmetic ingredients are based on the redox reactions. In this article, we summarized basic theories of redox titration and applications. Determination of unsaturation properties based on iodine or bromine number, quantitation of hydrogen peroxide or peroxide materials in several cosmetic ingredients and measurement of titanium dioxide, widely used sunscreen agent, in cosmetics are discussed here.

화장품 시장은 유통에 따라서 가격, 디자인, 제품 등의 요소가 결정되는 특수한 성격이 강하다. 본 연구에서는 화장품 특판 시장에서 나타나는 디자인적 차별성을 살펴 보고 향후 발전 방안을 모색해보고자 하는데 있다. 연구결과, 바디케어 특판 화장품의 경우 차별화를 강조한 형태, 함량을 강조한 형태, 사용자의 사용성을 강조한 형태등이 가장 큰 고려 대상이었다. 그리고 특판 시장의 경우에는 가격 경쟁력 문제를 디자인으로 보완할 수 있는 부분이 있다는 것을 알 수 있었다.

The changes of cosmetic industry regulation in the leading countries, such as E.C., America, Japan, initiated our research to suggest the direction of our cosmetics regulation. These countries are strengthening the post-monitoring system for the safety and cosmetic industry development. We propose the agenda for the development of the industry; the extension of cosmetics range, deregulation of the advertisement, implementation of the ingredient labelling, introduction of the product expiring date. Ultimately. it is necessary to introduce and extend current CGMP to enhance the company responsibility and to reinforce the post-monitoring.

Bupleurum falcatum L. is one of the medicinal crops and has excellent pharmacological activities such as reducing fever, sedation, inhibition of hepatopathy, anti-inflammatory, and anticancer. Currently, it is used for food or medicine, but the use as a cosmetic is insufficient, so the suitability and use value as a cosmetic material were reviewed. Using the Bupleurum falcatum L. extract, polyphenol, flavonoid, antioxidant, and anti-inflammatory tests were conducted. The total polyphenol content was 14.71±0.16 mg·TAE/g, and the total flavonoid content was 1.42±0.05 mg·QE/g. The antioxidant activity showed excellent activity in a concentration-dependent activative, and the NO expression inhibition ability was 61.21% at 1,000 ㎍/mL, confirming that the anti-inflammatory activity was excellent. Through this study, the antioxidant and anti-inflammatory effects of Bupleurum falcatum L. extract are excellent, so it is considered to be of sufficient value as a natural material for cosmetics.

L-Ascorbic acid 및 그 유도체는 항산화 작용과 미백작용 및 섬유아세포의 생장 촉진과 콜라젠 생합성의 증가시키는 효과가 있으므로 화장품에서 오래 전부터 사용되어 왔다. 본 연구에서는 생체에 대한 안전성과 안정성이 우수한 L-Ascorbic acid 유도체를 개발하기 위하여 인지질과 유사하게 L-Ascorbic acid 에 3-Aminopropane phosphoric acid를 결합하여 L-Ascorbic acid-3-aminopropane phosphoric acid diester를 합성하였다. ASA-APPA 는 2-Chlorotetrahydro-2H-1, 3, 2-oxazaphosphorine P-oxide 와 5, 6-isopropylidene L-Ascorbic acid 를 반응 시킨 후 산 사수분해 반응을 통하여 얻을 수 있었다. ASA-APPA는 수용액에서 안정성이 우수하였으며, 독성실험에서 무독성 물질이며, 인체 첩포 실험에서도 무자극 물질임을 확인하였다. 그리고, ASA-APPA 는 L-Ascorbic acid 와 3-APPA 의 혼합물과 거의 유사한 섬유아세포의 증식효과를 나타내었으며, melanoma 에 대한 멜라닌 생성 억제 실험에서 L-Ascorbic acid phosphate magnesium salt 와 유사한 효과를 보였다. 따라서 ASA-APPA 는 멜라닌 생성 억제 효과와 섬유아세포의 증식 효과를 갖는 새로운 화장품 원료로서 사용이 가능할 것으로 생각된다.
