Cosmeceuticals products we not the products simply for moisturizing and protecting skin but the ones for encouraging to make improvements on wrinkles and helping to whiten, tan, and protect skin against ultraviolet light. In a broader sense, they refer to products with aiming to maintain healthy condition of skin such that skin troubles could be improved or aging of skin could be delayed. However, cosmeceuticals should not have any side effects because they are applied to the whole body for a long period of time differing from medical products which are used on specific areas for a short time. The number of such cosmeceuticals has increased from 500 in 2001 to 2300 in 2003. In order to develop and broaden the scope of cosmeceuticals, the concept of cosmetics needs to be changed from caring skin to delaying aging of the skin and reviving cells. For this purpose, high-valued materials should be developed through basic researches related to the biological function of skin, in vivo experiment and reaction of skin in response to various stimuli using biotechnologies and bioengineering methods. At the same time, it should be proceeded to develop new nano materials for overcoming skin barriers and transfer matericals for helping to absorb effective substances and maintaining stability.

자외선 차단제는 화장품 원료 중 주요 자극원의 하나이다. 그러나 자오선 차단제를 고분자로 만들 경우 피부에 도포 되었을 때 경피흡수가 불가능 하여 피부 자극 문제를 해결할 수 있다. 이에 본 연구에서는 PVBC와 alkylhydroxycinnamate를 반응시켜 고분자 자외선 차단제를 합성하였다, PVBC는 benzylic chloride를 가지고 있는 고분자로서 이 작용기는 친핵성 치환반응이 용이하므로 side chain modification이 가능하다. PVBC와 alkyl hydroxycinnamate의 반응에서 반응성은 alkyl hydroxycinnamate의 크기와 반응에 첨가된 촉매의 종류에 영향을 받는다. 효율이 낮은 촉매를 사용할 경우에는 alkyl hydroxycinnamate의 크기가 작을수록 반응수율이 높았으며, 높은 효율을 갖는 촉매를 사용할 경우에는 alkyl hydroxycinnamate의 종류에 관계없이 반응수율은 100%였다. 실험에 사용한 PVBC는 평균 분자량이 55,000이었으며, 고분자의 구조와 분자량은 NMR과 GPC로 확인하였다. 고분자 자외선 차단제의 자외선 흡수 능력은 OMC에 비해 65 - 94% 였으며, caprylic/capric triglyceride에 좋은 용해도를 보여주었다.

The study aims to explore whether the Supplier's social medial activities and the consumer's social media activities mediate between the characteristics of purchasing cosmetics and the intention of purchasing. To answer this question, a total of 321 consumers participated in the study, and a self-report type of questionnaires were utilized to collect the data. For the data analysis, descriptive statistical analysis and structural equation modeling(SEM) were applied. The results from the study are as follows. First, the characteristics of purchasing cosmetics did not affect the intention of purchasing cosmetics. Second, both the Supplier's and the consumer's social media activities positively predicted the intention of purchasing, among which the consumer's activities were ascertained to make more influential impact on the intention of purchasing cosmetics. Third, both Supplier's and consumer's social media activities completely mediated between the characteristics of purchasing cosmetics and the intention of purchasing. More discussions are suggested for marketing strategies in the study.

In this study, Rosa multiflora was sampled through extraction, concentration, and freezing. The antioxidant efficacy of a mixture of R. multiflora extract and ascorbic acid was compared with a single ascorbic acid. The purpose of this study was to analyze the antioxidant efficacy through the synergistic effect of R. multiflora extract and ascorbic acid. The experiment measured electron donating ability, ABTS+ radical scavenging, SOD-like activity, xanthine oxidase inhibition activity, reducing power, FRAP, polyphenolic content measurement, and flavnoid content measurement. As a result, the complex showed higher antioxidant activity than the control group (ascorbic acid) in the electron donating ability test and the xanthine oxidase inhibitory activity test. In the case of the flavonoid content experiment, it was confirmed that RMW+A (272.1 mg QE/g), RME+A (90.6 mg QE/g), and RMW+A (79.4 mg QE/g) at a concentration of 100 ㎍/mL had a higher flavonoid content than the control group (19.0 mg QE/g). Therefore, the extract and ascorbic acid complex exhibited a synergistic effect compared to the single use. Therefore, it is thought that this complex will contribute to product stabilization and skin aging inhibition when used in antioxidant cosmetics.

오늘날 화장품 산업은 역동적으로 끊임없이 변화하고 있다. 화장품은 한 사회 구성원들의 다양한 욕구, 가치관 및 생할양식에 영향을 미치며 심지어는 국가의 정치적 기후나 경제적인 상태를 나타내는 지표역할을 담당하기도 한다. 즉, 화장품 과학은 예방의학, 건강과학이라는 차원에서 뿐만 아니라 미적인 차원에서 새로운 상품개발이 진행되어갈 것이다. 지금 우리는 21세기를 향하여 1990년대의 중반기에 들어섰다. 80년대는 물질 문명의 중심으로 생활의 질의 풍요로움을 추구하였으나 90년대는 소비자 우선의 풍요로움을 향수하는 시대가 되었다. 또한 여성이 사회진출, 고령화의 급속한 진전, 고 학력화, 개인의 가치관 존중 및 많은 생활패턴의 변화가 마음의 풍요로움을 구하는 사람들이 늘어나고 물질적 의존도로 부터의 탈피가 크게 강조되고 있다. 이에 마음의 풍요로움을 창조하여 연출하는 화장품산업의 역할이 고기능성에 의한 부가가치를 높이고 마음의 풍요로움을 지원하기 위한 연구개발에 중점을 두고 진행되어 가고 있다. 화장품을 여성들의 치장이라고 하는 주체적 행위에 도움을 주는 하드웨어라고 한다면 소비자의 마음은 소프트웨어로써 소비자 입장에서 만족할 수 있는 전략을 구사하는 아이디어가 있어야 하는데 그에 상응하는 대책으로 스킨케어를 들 수 있다. 스킨케어란 병든 피부를 제외한 여러 가지 유형의 피부를 화장품과 미용기기를 이용하여 그에 맞게 예방관리 하여 건강하고 아름답게 보호 유지하는 전문 분야이다. 즉, 스킨케어는 화장품 이용을 통하여 미래의 소비자들의 다양한 비용 욕구 및 소망에 효과적으로 대응할 수 있는 소프트웨어라고 할 수 있다., 또한 스킨케어는 화장품 뿐만 아니라 신체적 접촉을 통하여 안위를 제공하는 수단으로 단순한 피부손질이라는 문제에 그치지 않고 접촉을 통해 마음과 신체의 균형을 꾀하는 생명현상의 심층과 연관되는 중요한 의미가 있다. 스킨케어는 불어로 Soin Esthetique 라고 하는데 어원을 보면 손질, 처치, 보살핌 그리고 배려를 의미한다. 지금으로부터 200년전 독일의 미학자인 Baumgarten이 미는 인간에게 만족과 쾌감을 주는 대상이며 미는 보는 사람의 마음에 있다라는 감성의 미학에서 Esthetique라는 단어를 처음 사용했다. 다시 말하면 Soim Esthetique는 인간의 마음 만족과 쾌감을 주는 배려 있는 조치로써 여성이 화장을 함으로써 외모의 조화에서 마음과 신체의 균형을 꾀하는 생명현상의 심층과 연관되는 것과 마찬가지로 에스테틱과 화장의 심리는 매우 땔래야 땔 수 없는 불과분의 밀접한 관계라 볼 수 있다.

This study was pursued to measure skin feeling of cosmetics by mechanical methods. For this attempt, skin feeling of cosmetics such as spreading properties, tackiness, and residual greasy feeling after skin application was explored with the amount and kinds of cosmetic compositions-emulsifiers, waxes, thickeners, polyols, and oils. Furthermore, the relationship between these cosmetic compositions and viscometry of cosmetic products was studied. In case of emulsifiers, waxes, and thickeners, they showed strong correlation with both skin feeling and the value of phase angle, the property of viscometry, respectively, while polyols and oils were observed a special tendency neither skin feeling nor the property of viscometry. It leads to the conclusion that skin feeling may be corresponded to not values of a mechanical measure completely but a function of several properties. We expect that a better correlation can be discovered with additionally measured properties such as friction, volatility, etc.

This study aims to provide basic materials for marketing strategies of cosmeceuticals by investigating customers' recognition and satisfaction about cosmeceuticals targeting 161 adult men and women in their 20s to 50s and living in Seoul, Korea and then analyzing what should be improved for customers. According to the survey, many customers prefer cosmeceuticals due to the professionalism recognized by hospitals, the recommendation by doctors and the scientific image, though the recognition about cosmeceuticals is low among customers in their 40s or older because they are unfamiliar with the term. The survey also shows that the satisfaction about cosmeceuticals is very high in that 94.41% out of 49.85% total users said they were willing to repurchase them, while 72.22% out of 50.15% total nonusers said they wanted to purchase them. The greater knowledge about skin, the higher the interest in cosmetics and the aesthetic practice rate. When it comes to comparing cosmeceutical users and nonusers in choosing cosmetic products, the greater knowledge about skin, more nonusers consider brand recognition (r=.222, p<.05) and cosmetic ingredient (r=.245, p<.005); and more users convenience (r=.162, p<.05). Now that total customers' awareness of cosmeceuticals remains low yet, therefore, it is considered necessary to steadily promote them, enhance repurchase factors, and come up with strategies differentiated from ordinary cosmetics.

Amidst the rapid growth of the vegan cosmetics market, consumer orientation towards environmental and ethical values has been intensifying. However, research on this subject remains limited. This study delves into the relationship between consumer value perception, environmental motivations, and perceived barriers influencing the purchase intentions of vegan cosmetics. Conducting a PLS-SEM analysis on a sample of 300 women with experience using vegan cosmetics, it was discerned that monetary value, social value, brand value, emotional value, quality value, and environmental knowledge play significant roles in influencing purchase intentions. The moderating effect analysis highlighted image barriers and value barriers as crucial factors. Through Importance-Performance Map Analysis, emotional value emerged as a pivotal element in strategizing to strengthen the purchasing intentions for vegan cosmetics. This research contributes both theoretically and practically to enhancing the competitive edge of the vegan cosmetics market and promoting sustainable consumption behavior.
