In this study, in an attempt to search for functional cosmetic ingredients from higher fungal, we have produced exopolysaccharides (GF-l, approximately carbohydrate 75％, protein 25％) and polysaccharide (GF-2) of mycelium extract, by submerged culture of Grifolafrondosa. For applications in anti-aging cosmetic field, we investigated the diverse biological activities. Antioxidant activity and inhibition of Matrixmetalloproteinases (MMPs) were investigated enzymatic assays by measuring the superoxide scavenging activity using xanthine-xanthine oxidase system and the proteolytic activity of MMPs using EnzChek Collagenase/Gelatinase kits, respectively. GF-l polysacchairde showed inhibition of superoxide radical by 90％ at a concentration of 0.2％ (w/v) and inhibition of collagenase by 45％ at 0.2％ (w/v). GF-2 polysaccharide of mycelium extract also exhibited good antioxidant activity. However, MMPs inhibition activity was relatively lower level compared to GF-l polysaccharides. The treatment of human dermal fibroblast (HDF) with GF-l and GF-2 polysaccharides increased the proliferation of fibroblast by approximately 23-25％ at a concentration of 0.5％ (w/v), also showed collagen synthesis increase in HDF by about 50％ at 0.5％ (w/v) compared to that of untreated control. We also report the moisturizing effects of polysaccharides in cosmetic products (O/W emulation) and its own ingredient, in vitro and in vivo. The GF-1 polysaccharide showed higher moisturizing ability than sodium hyaluronate, which is the most commonly used moisturizers ingredient. These results suggest the GF-l polysaccharide, protein-bound polysaccharide, may be used as an ingredient for new moisturizing and anti-aging cosmeceuticals.

The present study analyzed the consumer acceptance of labels, satisfaction with cosmetics after purchase, the relationship between consumer acceptance of cosmetics labels and satisfaction with cosmetics as viewed by type of distribution channel. The study was implemented through a descriptive survey method based on a self-administered questionnaire. The sample consisted of 759 women between the ages of 21 and 49, residing in the area of Seoul, Gwangju, and Gyeonggi Province. There were significant differences in the levels of consideration of labels among consumers from each type of distribution channel. Consumers that prefer door-to-door sales consider the information about ingredients more crucial than consumers who prefer other types of distribution channels, department store consumers consider manufacturer information more important, and consumers who prefer specialty stores/chains and discount stores consider the date of manufacture less important than other types of distribution channels. Significant differences were found in consumer satisfaction with cosmetics after purchasing among consumers from each type of distribution channels. A significant relationship was found between the level of considering the product information listed on the labels and the satisfaction with the cosmetics. With respect to most of the factors, a higher level of label consideration was correlated with a higher satisfaction with cosmetics after purchase.

Deficiency of collagen regeneration, denaturalization of fibers, increased melanin synthesis and reactive oxygen species are important factors inducing deterioration of healthy skin function. They induce freckles and decrease in skin elasticity. Vitamin C, vitamin A and their derivatives have been used as cosmetic ingredients for improvement of these problems but they have various problems. We have been developing the various derivatives of these ingredients. In this study, we investigated whitening effect of 3-o-cetyl-L-ascorbic acid (VCCE), a new vitamin C derivative. The VCCE inhibited melanogenesis in a dose dependent manner(44 % at $20\;{\mu}g/mL $) and tyrosinase expression. For 8 weeks, we also investigated skin brightening effect of VCCE on pigmented spots in UV-irradiated human skin. In results, VCCE showed a statistically significant skin whitening effect by mechanical and visual evaluation. Taken together, our findings suggest that the VCCE has potential benefits as an active ingredient for whitening cosmetics.

This study has purposes : evaluating how safe the skin is when applied with the Spicules-containing cosmetic, and whether Diamond-spicules is permeated into the skin and showed the efficacy of the active ingredients well. For these aims, women in their 30s and 60s were surveyed for skin irritation and changes after applying cosmetics to their skin for four weeks. As a result, Spicules-containing cosmetics were safer on the skin than general functional cosmetics, and in particular, in the case of cosmetics containing Diamond-spicules, statistically significant results (p<.001) were obtained in improvement of anti-wrinkle, firmness, moisturizing, whitening, alleviation of inflammation, and sensitivity. Thus, It has been proved Diamond-spicules containing functional active ingredients, not only as transdermal delivery system, but also can be used as multifunctional cosmetic material.

Certain types of anti-inflammatory components and whitening components were in practical use as the active ingredients of quasi drugs expected to display their pharmacological actions. However, only twenty years at most have past since the introduction of cosmetics that not only physically change the condition of the surface of the skin, but also promote skin homeostasis from by acting on the physiological mechanisms of the skin. Since then, much effort hasa been made to find new active ingredients suitable for full-scale development, and the term "cosmeceutical" has often been coined to describe cosmetics containing pharmacologically active components. In this report, the prospects of cosmeceuticals will be discussed on the basis of a review of the history of the development of current skin-care products.

The customized cosmetics preparation management qualification system was implemented in March 2020, and it served to create jobs by developing professionals and vitalizing the cosmetics business. However, various problems such as high examination fees, suitability of questions, and utilization in industries are emerging. This paper attempts to prevent disputes that the system can cause and suggest ways to improve it by researching customized cosmetics, the industry status, and comparing foreign cosmetics laws. There is a kind of opinion that laws should be eased for this industry and the other opinion that expertise is necessary in this field because of safety. The system now has adverse effects due to a failure to adjust the difficulty of the exam. Cosmetics are not prescription-based, so they are routinely used. However, some toxic ingredients can cause side effects if they do not conform with certain standards. Also, it is difficult for a case to lead to lawsuits because most consumer damages related to cosmetics are individual. In addition, as e-commerce develops, there is a growing possibility of seeing more consumer damages. If safety and distribution issues, which experts are concerned about, escalate, the private dispute settlement system (among the ADR systems) should be activated as a resolution method.

Polyethylene glycol (PEG) is widely used in cosmetics as a surfactant, detergent and emulsifier. During the manufacturing process, 1,4-dioxane, which is toxic to humans, can be produced as a by-product by dimerization of ethylene oxide. As consumers' interest in cosmetic ingredients has increased, the need for safe emulsion research without PEG ingredients in the personal care market has increased. With increasing consumer interest in cosmetic ingredients, the need for safer emulsion research without the PEG ingredient in the personal care market has increased. In this study, we aimed to develop and stabilize nanoemulsion formulation without PEG. Response Surface Methodology (RSM) was used to develop optimized nanoemulsion formulations. Surfactant content (2~4%), oil content (4~8%) and polyol content (12~24%) were set as independent variables as a result of preliminary experiments for determining independent variables and ranges. The particle size, zeta potential, turbidity, and polydispersity index of the formulation were measured as response variables. As a result of measurement of the prepared nanoemulsion by FIB (Focused ion beam), spherical particles were found to have a size distribution of 100 to 200 nm. The stability of each formulation was evaluated for 30 days at each temperature ($4^{\circ}C$, $25^{\circ}C$, and $45^{\circ}C$). The optimal formulation considering the optimum particle size, turbidity, polydispersity index and zeta potential was found to be surfactant (2%), oil (8%) and polyol (24%).

Council Directive 76/768/EEC forms the basis of the actual legislation of cosmetics in the European Union (EU). After a short introduction on the background and philosophy of this legislation, the key points will be discussed. In particular, attention will be given to the basic principles for safety and in this context the effects of the implementation of the 6th Amendment (Council Directive 93/35/EC) will be analysed. The major points for discussion will be: the safety requirements for cosmetics and the final responsibility for bringing these products on the EU market; the EU concept of safety of the finished product based on the safety of the individual ingredients; the existence of positive and negative lists of ingredients and the requirement for a European dossier for all finished products. Special attention will be given to the use of validated alternative methods and the consequences of the new proposal of a 7th Amendment. Finally, the safety evaluation as it is done by the SCCNFP (Scientific Committee on Cosmetics and Non-Food Products) in the case of an ingredient present on the positive lists and the evaluation done by a safety assessor in the case of a technical information file for a finished product, both will be discussed in detail.
