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. In the patented technology for pets, a patent has been registered for natural product material composition and formulation ratio for skin moisturizing, skin improvement, thinning, and inflammation symptom relief. As a result of this award, it was confirmed that research and development are still insufficient compared to the consumption demand of the pet cosmetics market, and it is believed that industry analysis and development research in related fields should be actively carried out.

Animal testing was used traditionally in the cosmetics industry to confirm product safety, but has begun to be banned; alternative methods to replace animal experiments are either in development, or are being validated, worldwide. Research data related to test substances are critical for developing novel alternative tests. Moreover, safety information on cosmetic materials has neither been collected in a database nor shared among researchers. Therefore, it is imperative to build and share a database of safety information on toxicological mechanisms and pathways collected through in vivo, in vitro, and in silico methods. We developed the CAMSEC database (named after the research team; the Consortium of Alternative Methods for Safety Evaluation of Cosmetics) to fulfill this purpose. On the same website, our aim is to provide updates on current alternative research methods in Korea. The database will not be used directly to conduct safety evaluations, but researchers or regulatory individuals can use it to facilitate their work in formulating safety evaluations for cosmetic materials. We hope this database will help establish new alternative research methods to conduct efficient safety evaluations of cosmetic materials.

We investigated the inhibitory effect of whitening materials with growth factor or alone on melanomas derived from Human (B-16) and mouse (SK-MEL-31) using melanin content. Melanin content was determined by the absorbance value at 470nm per cells. we used the growth factors known as activators of Adenylate cyclase, Protein kinase C and tyrosine kinase pathway separately. In addition, we compared the action of UV-induced with non-biological growth factor with whitening materials in melanomas derived from Human and mouse. The results showed that the aspect of inhibitory effect of whitening materials on B16 and SK-MEL-31 was not different. And, the action of each growth factor involved in the differentiation and proliferation of melanoma on the inhibition of melanogenesis in B-16 and SK-MEL-31 using whitening agents showed no difference. Also, The action of UV -induced and non-biological growth factors didn't exhibit different pattern on the effect of whitening agent in B-16 and SK-MEL-31.

Emulsion is a dispersion system among liquids which are not miscible together. There are numerous cosmetic raw materials which have different physicochemical properties. Therefore, emulsion technology is very useful in cosmetics. With the development of emulsifier, several emulsification technologies have been developed. Since HLB method by Griffin in 1950's, PIT method, gel method, and D-phase methods, etc, have been developed. Recently, the application of natural emulsifier and polymeric emulsifier increases in cosmetics in order to achieve enhanced safety and biocompatibility. Besides nano-emulsion, multiple-emulsion, liquid crystal emulsion, and Pickering emulsion have been developed and applied as means of differentiating appearance and texture of products and achieving enhanced delivery of active ingredients. Meanwhile, the application studies of nano-dispersed structural system such as liposome or cubosome are on progress. Liposome is a bi- or multi-lamella layer dispersion system composed of amhiphilic molecules - phospholipids which are main components of plasma membrane. Cubosome also is a nano-sized dispersion system composed of a specific molecule like glyceryl monoloeate derived from natural products. And it has a cubic bicontinuous structure in water due to its unique molecular structure. Incorporating compounds (active materials) into such nano-particles can increase biocompatibility and delivery efficiency of target compounds. Manufacturing process and application of cosmetic emulsions and nano-particles are briefly introduced in this paper.

The product name is the main factor in working out the marketing strategies, because it offers the information of the products, and reflects functions, materials, expectable effect, and the trends of the cosmetics. The purpose of this study is to analyze the type of language, the number of syllabus, and the composition method of the product names for the domestic cosmetics brands. It analyzes 120 products of skins and lotions from 10 brands of the Amore-Pacific. The results of the study are as follows; Firstly, foreign words and languages are mostly used in the product names, and the mixed words are used more than the korean and the chinese characters. Secondly, 7-15 syllabus is the most widely used number for the brand names. It is rare to use only one word for the brand name and it is general to use the combination of relative words that describes the product well. Thirdly, it is found to be common to have 'product line + product type' for the composition method. This kind of composition method uses the words that indicates skin troubles.

Since, side effects of antibiotics are frequently emphasized these days, their use is gradually diminishing, and alternative drugs are being developed. We have sought to reintroduce them as raw materials for human health as conventional 'weapons' that have been retired after their historical duties. In this study, we investigated the anti-inflammatory effects of lincomycin (LIN), on lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. Our findings show that LIN potently inhibited production of LPS-induced proinflammatory mediators, such as nitric oxide (NO) and prostaglandin E₂ (PGE₂), without cytotoxicity. Consistent with these findings, LIN strongly decreased protein expression levels of inducible NO synthase (iNOS) and cyclooxygenase (COX-2). Furthermore, LIN reduced pro-inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β. To further elucidate the mechanisms of these inhibitory effects of LIN, we studied LPS-induced IκB-α degradation, and mitogen-activated protein kinase (MAPK) phosphorylation. LIN suppressed downregulation of inhibitory κB (IκB-α) degradation, and the phosphorylation of the c-Jun N-terminal kinase (JNK) pathway. Based on these results, we suggest that LIN may be considered a potential candidate as an anti-inflammatory cosmetic or a medicine for human health.

This objectives of this research was to look into the actual state of fashion wearing purchase and makeup purchase to recognize the interrelationship between fashion and makeup styles by selecting words used for fashion image and cosmetic style. Such study can offer basic materials for choice of makeup style by each fashion style. Most information on fashion and cosmetics were obtained through the internet. However, a lot of information on cosmetics were also obtained through TV. Therefore, if fashion companies use both internet and TV for advertising, more effect on purchasing might be obtained. The design and color are important standards for selecting clothes. However, the quality and price of clothes are essential standards for purchasing cosmetics. Therefore, for fashion companies, they need to pay more attention to design and color. However, for cosmetic companies, they need to take notice of quality and price. When image words were extracted, fashion images showed the following words: natural, romantic, elegance, casual, and avant-garde, while makeup images showed romantic-casual, elegance, avant-garde, and natural. Regarding the interrelationship between fashion style and makeup style, natural and casual fashion style were harmonized with natural makeup while romantic fashion style was associated with romantic makeup. The fashion style of elegance and avant- garde was associated with elegance makeup. Therefore, similar images were found between fashion and makeup styles.

The cosmetics industry faces a significant challenge in addressing the decreased recycling rate of cosmetic containers due to the composite materials used to meet consumers' aesthetic satisfaction. To address thees issues, eco-friendly packaging solutions such as refill packaging and single-material use have been developed. However, the market for eco-friendly cosmetics packaging requires a product that meets consumers' demands for aesthetics, sensitivity, and eco-friendliness while also performing as well as existing products. This study presents a solution to the challenge of the decreased recycling rate of cosmetic containers by developing a new cosmetic packaging product for cream formulations. The product features an easily separable and dischargeable internal refill container, while maintaining the design aesthetics of the external container. Through various tests, the product was shown to be of equivalent quality and performance to existing cream cosmetic packaging, with no leakage or defects observed. Furthermore, the use of a single-material polypropylene refill container is expected to contribute to the improvement of the plastic recycling rate.

The growing demand for functional cosmetics, driven by modern individuals' quest for healthy and aesthetically pleasing skin, is being challenged by reports of side effects and toxicity associated with these products. This underscores the importance of exploring natural plant-based materials for functional cosmetics. This research focuses on the assessment of antioxidant and whitening properties of mixed extracts from Ipomoea nil, Arctostaphylos uva-ursi, and Angelica gigas Nakai, all of which have proven pharmacological benefits. The study evaluated the extracts' total polyphenol and flavonoid contents, ABTS and DPPH radical scavenging activities, SOD-like activity, and xanthine oxidase inhibition to determine their antioxidant capabilities. Moreover, the whitening potential was investigated through tyrosinase activity and melanin production assays, alongside a cytotoxicity evaluation via a cell viability test. The findings revealed that the extracts, IAA-1 to IAA-4, demonstrated both antioxidative and whitening capabilities without exhibiting cytotoxic effects. Notably, the extract IAA-4, processed through ultrasonic and ultrahigh pressure extraction, exhibited superior effectiveness. These results indicate that the cavitation formed during ultrasonic irradiation effectively destroys the plant cell wall by creating high pressure, and as a result, it is judged that useful components are easily extracted. As a result of the study, it was confirmed that the IAA-4 extract could be applied as a material for functional cosmetics.

We describe here how we can use microfluidic technologies for fabricating functional materials that could be potentially utilized in cosmetics; these include void structures, functional particulate materials, shell materials, and multi-layered colloids. We can obtain these functional materials as microfluidic approaches provide precise control over both outer dimensions and inner morphology of emulsion drops in picoliter-volume scales with high throughput. We have confirmed that this technique has a great potential to fabricate novel particles and capsules with a variety of chemical compositions as well as higher orders of layers. This microfluidic approach will allow us to develop a lot of new techniques that are useful for a variety of applications, including delivery systems, chemical separations, bio-sensing, actuators, and so on. We do believe that these new techniques will help cosmetic industry not only give rise advanced functional materials and systems but also widen its product categories.
