In this review, the use of air bubbles in the pharmaceutical and cosmetic formulations was discussed. The foam bubbles show different characteristics depending on the foaming agents and foam generating devices. The foam bubbles are generated in the form of dispersion of gas bubbles in a solvent. The assessment of stability and rheological properties of bubbles are the starting point for the formulation to be used. Pharmaceutical and cosmetic uses of bubbles are substantially growing, and the foam formulations of drugs can be used for rectal, vaginal, and dermal symptoms. The foam formulation is used in hair mousse, makeup foundation, and sunscreen cosmetics in basic cosmetics. Recently, a lot of studies and patents have been filed in stabilization of active ingredients and delivery of the active ingredient in terms of foam formulations. In the future, foam formulations are expected to be used as novel cosmeceutical formulations.

K-Cosmetic 열풍으로 국내외 화장품 시장 규모가 커지면서 화장품 개발에 대한 관심이 증대되고 있는 반면 화장품 원료 데이터 베이스에 대한 네트워크가 개발되지 않은 실정이다. 본 논문은 식품의약품안전청에서 공시한 화장품원료기준 성분사전에 의거한 화장품원료를 기준으로 기능을 분석하여 각 기능에 해당하는 원료를 연결하여 네트워크를 구축하였다. 본 네트워크를 활용하여 화장품 제조 시 필요한 기능이 최적화된 원료를 탐색하여 활용함으로써 원료의 구성을 최소화 하면서 본래의 기능을 구현하여 화장품 생산 비용 감소 및 효율성이 극대화 될 것으로 예상된다.

The characteristic aroma of Gardenia Absolute Oil made from Gardenia Jasminoides Ellis was investigated by GC and GC-MSD and by sensory evaluation The method of GC Analysis was used Double Column System by Carbowax 20M /SPB-1 of Pola/nonPola columns. And the result data of analysis was checked automatic Relent ion Indexs Match System by GC Workstation. A total of 51 compounds were identified in Gardenia Absolute Oil, including t entatively erstimated 9 compounds. The major components were Linalool, Farnesene of various form, Jasmin Lactone, Gamma undecalactone and Cis-3-hexone derivatives.

This study aims to develop a new analytical method to detect zinc pyrithione, the ingredient of cosmetics appointed as restricted ingredients and used as preservatives.. The analytical method was based on data gathered from the relevant literature. Information about the amounts of these ingredients was researched in order to select the base-matrix materials used to validate the analytical method. After selecting and preparing the base-matrix materials, the analytical method was validated by method validation procedures. The analytical method was verified first by inter-laboratory validation and then through analyzing the cosmetics sold in the market. Based on the results of this study, guidelines are proposed for the analysis of restricted ingredients in cosmetics, which will provide a method to test the cosmetics circulating in the Korean market. The use of the proposed guidelines will increase the quality of the cosmetics as well as the safety of human health, which will enhance the competitiveness of the Korean cosmetics industry and lead to an increase in the exportation of cosmetics.

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.

Exessive UV radiation causes a lot of problems in our skin. In order to find out the alternative UV absorber that can safely be used in cosmetics, we have screened various natural extracts in terms of their UV absorbing effect. Some natural extracts, which possess antioxidative activities, have also been found to retard the oxidation process in our experiment. Natural compound such as 7-hydroxycymopol, baicalein, etc. could be transformed into adjuvant UV absorber by chemical modification. In cosmetics, its chemical stability against UV radiation, exposure to oxygen and other factors could be improved by using the silicone or W/S type emulsion. The values of MED (minimal erythema dose) were improved to 0.10 ${\pm}$ 0.02∼0.11 ${\pm}$ 0.02 by adding this natural extract into the cosmetic formulations. In conclusion, the results of the present study show that natural extracts could be used as an adjuvant UV absorber, if they are stabilized.

Anoectochilus formosanus, commonly known as "Jewel Orchids", which has been used in traditional folk medicines for feber, pain, and diseases of the lung and liver in Taiwan. We artificially cultured Anoectochilus formosanus plantlet by using the bioreactor culture system for this study from Anoectochilus formosanus. Previously, several studies have been reported on pharmacological activities of lipid-metabolism, hepatoprotective activity, anti-tumor activity and immuno-stimulating effects but other efficacy were not well known as a cosmetic ingredient for skin care. In this study, we investigated the effect of melanogenesis in B16 mouse melanoma cells and lipid droplet accumulation in 3T3-L1 preadipocytes about Anoectochilus formosanus plantlet extract. We report that Anoectochilus formosanus plantlet extract inhibits the cytoplasmic lipid droplet accumulation through adipogenic differentiation of preadipocytes as well as inhibition of tyorsinase activity and melanogenesis. As a result, our findings indicate that Anoectochilus formosanus plantlet extract may be the potential natural ingredient for whitening and slimming cosmetic products.

Gas chromatography serves to separate the mixtures into its components, and mass spectrometer is used to analyzing of unknown compounds. But there are many problems the identification of horn compounds using by GC only. As this reason GC/MS a very powerful analyzing technique. Mass spectrometer consists of 1) inlet stem 2) ion source 3) Bass filter 4) detectors and 5) data system. There are two analyzing modes in the GC/MS, those are scan and SIM(selected ion mom toping) modes. Scan mode is used when analyzing unknown compounds and SIM mode al lows the mass spectrometer to detect specific compound with very high sensitivity. As GC/MS applications for the analysis of cosmetic products, volatile compounds in lotion, earn foundation and hair color, and carbon distribution of fatty acids in soap were performed. Also as a new sample pre-treatment technique, head space sampler/GC/MS introduced in order to analyze the volatile compounds in a toothpaste.

Pycnogenol extracted from pine bark is a component with great antibacterial activity and antioxidant effect. It is applied as a natural anti-inflammatory agent with various medical effects including anti-inflammatory effects, regulation of blood pressure, regulation of the immune system, and inhibition of cancer cell growth. However, research related to cosmetics is limited. Therefore, in this study, the effect of Pycnogenol on the skin was studied through a clinical approach. Changes in skin condition were observed after using cosmetics with Pycnogenol and without Pycnogenol for 6 weeks for 10 clinicians in each group. We observed the effect of pore reduction, wrinkle reduction around eyes, a decrease of the number and angle of loose pores, and reduction of pigmentation. Therefore, cosmetics containing Pycnogenol have the effect of improving skin problems of aging skin.
