There are people who are sensitive to cosmetic ingredients, such as pregnant women and skin disease patients. There are also people who experience side effects from cosmetics. To avoid this, it is cumbersome to search for harmful ingredients in cosmetics one by one when shopping. In addition, knowing and remembering functional ingredients that suit you is helpful when purchasing new cosmetics. There is a need for a system that allows you to immediately know the cosmetics ingredients in the field through photography. In this paper, we introduce an application for smartphones, <Hwa Ahn>, which allows you to immediately know the cosmetics ingredients by photographing the ingredients displayed in the cosmetics. This system is more effective and convenient than the existing system in that it automatically recognizes and automatically classifies the ingredients of the cosmetic when the camera is illuminated on the cosmetic ingredients or retrieves the photos of the cosmetic ingredients from the album. If the system is widely used, it is expected that it will prevent skin diseases caused by cosmetics in daily life and reduce purchases of cosmetics that are not suitable for you.

본 논문에서는 화장품의 효율적 구매를 위한 화장품 성분표를 분석하고 정보를 전달하는 기능의 시스템을 제안한다. 이 시스템에서는 화장품 성분표에 최적화시킨 OCR (Optical Character Recognition) 모델을 사용해 화장품 성분표를 촬영한 영상에서 인식한 문자 데이터를 추출한다. 이 문자 데이터를 통해 얻은 화장품 성분이 사용자 피부 유형에 적합한지 구축된 데이터베이스와의 비교를 통해 소비자에게 최종 전달된다. 200개의 화장품 성분표 영상을 사용해 제안하는 화장품 성분표 분석 모델의 성능을 평가한 결과 80.348%의 정확도를 보였다.

많은 화장품이 출시함에 따라 고객들이 자신의 피부 상태에 맞는 화장품을 고르는 것에 대한 어려움이 증가하게 되었다. 기존의 화장품 추천 프로그램들은 해당 프로그램의 DB에 존재하는 화장품들에 대한 추천 밖에 하지 못한다. 본 논문에서 제안하는 새로운 화장품 추천 방법은 화장품을 구입하기 전에 상자 표면에 적힌 성분을 사진으로 찍어 단어 별로 추출한다. 추출한 단어를 DB에 저장되어 있는 성분 이름과 비교하여 화장품 성분만 구분한 뒤 k-최근접 이웃 알고리즘과 내용 기반 기법을 이용하여 사용자에게 맞는 화장품인지 판단해준다. 화장품의 성분표를 통해 DB에 없는 화장품이라도 즉석에서 사용자의 정보와 비교하여 적정도를 분석할 수 있다. 또한 사용자의 화장품 구입 성향으로 화장품을 추천해주어 사용자의 화장품 선택에 도움을 준다.

본 논문에서는 다양한 화장품 회사의 제품들을 사용자들이 자신이 사용하고 있는 화장품의 제조 성분을 실시간으로 사용자가 알 수 있게 하여 구매 시와 사용할 때 효과와 부작용 등을 파악하여 사용자에게 맞는 화장품 정보를 제공하는 맞춤형 화장품 성분 정보시스템을 설계하였다. 본 논문에서 제안하는 시스템을 설계하기 위해 미국의 환경단체에서의 화장품 성분 안전도 정보를 바탕으로 데이터베이스와 SQL에 대해 조사 및 분석하여 사용자 맞춤형 자가 화장품 성분 정보 시스템을 설계 하였다.

This study attempted to secure competitiveness in the cosmetics market and provide basic data needed to promote sales and PR after reflecting consumer demands and needs in the development of cosmeceuticals. For this, it investigated their perception regarding the ingredients and efficacies of cosmeceuticals and repurchase intention among a total of 193 adults in their 20-50s who have had prior experience of buying these types of products from an online shopping mall as the importance of cosmeceuticals is emerging. According to a survey on consumer perceptions regarding the ingredients of cosmeceuticals by gender, there was a clear difference between men and women. In particular, when asked about the ingredients of whitening cosmetics, the percentage of male respondents was as low as 30.8% with a significant difference between men and women (t=31.688,p<0.001). In addition, most consumers were very aware of the efficacies of the ingredients of cosmeceuticals on the skin. In terms of actual repurchase intention, however, a significant difference was found by gender and product type in 3 different cosmeceuticals. In other words, men were lower than women in terms of awareness of cosmeceuticals and repurchase intention. Therefore, the development of a plan which satisfies both men and women, easily labels ingredients and meets consumer needs and demands through proper pricing policy are needed during the development of cosmeceuticals.

World consumers are now focusing on their health, well-being and appearance more than ever before. This trend is creating heightened demand for products formulated as cosmeceuticals with active ingredients. A significant number of innovative formulations are now being used in cosmetics with real consumer-perceivable benefits and optimized sensory attributes, resulting in an economic uplift of cosmetic industry. To obtain skin care formulations with real consumer-perceivable benefits through dermal delivery of active ingredients, formulators are resorting to technology that until recently was used in pharmaceutical products. These various delivery systems are now being used in cosmecuetical formulations. Novel delivery systems reviewed here possess enormous potential as next-generation smarter carrier systems.

Betamethasone propionate, an anti-inflammatory glucocorticosteroid, was detected in cosmetics with no indication on the label of this compound as an ingredient. The product was formulated as a topical spray or shampoo and labeled to contain zinc pyrithione as the active ingredient. A thin-layer chromatographic analysis was carried out on silica gel plates to provide a first indication about the presence of a compound with steroid structure and reactivity; then high-performance liquid chromatography (HPLC) separation allowed the identification of the corticosteroid agent and its quantification. To identify the corticosteroid agent from these commercial samples we collected the fractions suspected to have ketol steroids by prep HPLC and identified the compound as betamethasone propionate by NMR and MS spectrometry. Then we synthesized the standard for the betamethasone 17-propionate and 21-propionate and quantitate the corticosteroids from the sample by HPLC with that standards. By this method we identified the corticosteroid compounds from some commercial cosmetics such as zinc pyrithione sprays. The finding of betamethasone propionate in the products was shown by comparison to an authenticated standard of betamethasone propionate by retention time on reverse-phase HPLC. Two of the tested products contained betamethasone propionate at the levels of 0.005 ${\sim}$ 0.02% and the others were free of betamethasone propionate.

Natural halloysite is mostly found in the form of a tubular structure with a 15-125 nm internal lumen. This kaolin clay can be used for encapsulating a liquid ingredient of cosmetics and for immobilizing an inorganic solid-phase ingredient. In this paper, the encapsulation and immobilization procedures are introduced and two example applications are reviewed to demonstrate the usefulness of halloysite as a cosmetics substrate. It may help attract more interest in cosmetic applications of halloysite and thus spur more research on the utilization of natural clays.

This study was conducted to determine 16 preservatives and 18 UV filter ingredients levels in 100 sunblock products. The order of detection rates of preservatives was phenoxyethanol (n=61), benzoic acid (n=19), methyl paraben (n=11), benzyl alcohol (n=8), propyl paraben (n=7). Also the order of detection rates of UV filter ingredients was titanium dioxide (n=81), ethylhexyl methoxycinnamate (n=69), zinc oxide (n=48), ethylhexyl salicylate (n=48), bis-ethylhexyloxyphenol methoxyphenyltriazine (n=44). The content of the detected preservatives and UV filter ingredients was within maximum allowed amount established by KFDA. In addition, preservatives and UV filter ingredients, which were not labeled in the products, were detected in 31 and 2 products respectively.
