The aim of this study is to examine the patterns of expressing contemporary beauty from the perspective of Laotzu's philosophy in order to suggest its concept and characteristics and to suggest specific cases through cosmetics advertisement. In doing so, the study attempted to understand that contemporary beauty is more humanistic and liberal in terms of expression patterns than in any other time period. The research results are as below. The frame concept of Laotzu's philosophy includes 1. Naturalness, 2. coexistence in Conflict, and 3. Non-otherness. The characteristics of contemporary beauty are natural and healthy, People can foresee changing beauty by the cycle of life and, by admitting this philosophy, people can understand one's individuality and discover self-esteemed beauty. Also, the results from the cases of cosmetics advertisement are as below: 1. Naturalness was remarkable. Such phenomenon was common in representative brands of the research subjects. Expression pattern was based on soft, natural make-up and hair style. 2. For conflict and coexistence, they introduced the ancient image of the situation, and the situational image using food and herbs demonstrated a functional, situational image, which was used for the cosmetics advertisement based on the mutual coexistence concept instead of dichotomy of period or material. 3. Non-otherness advertisement, of which there was none, we expected that maximized marketing effect would be achieved if non-otherness cosmetics advertisement expressed the contemporary beauty because it could solicit sympathy form many consumers.

Recently, consumers using cosmetics have a great interest in raw material safety. Among them, interest in natural preservatives is increasing, and as the demand for cosmetics excluding paraben preservatives increases, a method of replacing synthetic preservatives with antibacterial essential oils is being considered. The antibacterial effect of essential oils depends on the components, concentrations and interactions between the main active compounds. Effective preservatives should have antimicrobial activity against a wide range of strains even at minimal concentrations. All preservatives should be considered to increase skin concentration and cause skin irritation and allergic reactions. Consumers recognize that essential oils from nature are safe, but some should be careful because they can cause contact allergies or phototoxic reactions. As such, it is important to balance natural preservatives with maximum preservative effects and low toxicity. This paper describes the characteristics of essential oils focused on antibacterial properties, efficacy and safety as cosmetic preservatives.

Due to social phenomena such as rapid aging in Korea, nuclear familyization, single marriage, and low birth rate, the number of Companion animals and the number of households with Companion animals are increasing due to the increase in single-person households. In fact, one out of every four households has a pet, and the scale of the industry is expected to reach 6 trillion won in 2027. In particular, in a situation where the Companion animal cosmetics market is in the spotlight amid the diversification of the pet industry, there is a great lack of research on related research and industry development methods. Accordingly, this study attempted to search and analyze academic data, patented technologies, and the latest data related to pet cosmetics and provide them as basic data for the Companion animal cosmetics industry, and the results are as follows. Academic data included verification of the effectiveness of natural materials to improve the skin condition of dogs, analysis of the pet cosmetics industry, and research on ICT-converged pet cosmetics, and the industry was mainly cleaning cosmetics, with pet shampoo launches in Amorepacific, LG Household & Healthcare, and Aekyung.

Steroids have a temporary skin improvement and whitening effect by controlling vasodilation, but they also cause side effects when used for a long time. Therefore, steroids were designated and managed as raw materials that cannot be used in cosmetics in Korea. However, steroids are continuously being detected in cosmetics, causing social issues. In this study, we developed a certified reference material (CRM) for the determination of steroids such as hydrocortisone in cosmetics. A cream-type cosmetic CRM was manufactured and subsequently certified following the guidelines outlined in ISO Guide 35. Homogeneity, short-term stability, and long-term stability were evaluated using isotope dilution mass spectrometry (ID-MS). The certified values were determined by using NIST's primary reference material to ensure traceability. From now on, we intend to supply the certified reference material as a cosmetic CRM to national and international companies, as well as research institutes after certification as certified reference material from KOLAS and registering on COMAR.
