Nanoparticles are substances that are smaller in size and smaller than cells that make up the skin. Therefore, they are very suitable as mediators for transmitting drugs or genes across cell membranes, and also deliver specific ingredients into the skin.In this study, nanoparticles were extracted from mugwort and particles of around 100 nm were obtained through dynamic light scattering (DLS), and the results of concentration-dependent enhancement of cell viability in fibroblasts were obtained through MTT assay. In addition, it was confirmed that the COL1A1 mRNA expression level was increased and the IL-6 mRNA expression level was decreased through the quantitative real-time PCR analysis method. Moreover, as these nanoparticles were confirmed to be stable, they can be applied not only to cell experiments but also to cosmetic formulations. While the demand for plant-derived ingredients continues to increase, excluding chemical ingredients from the recent cosmetics industry trend, there is a limitation in that there are few research results suggesting the application field of plant-derived nanoparticles. Therefore, in order to overcome the limitations of the cosmetic industry at the present time, the results obtained in this study present nanoparticles derived from Artemisia princeps (NDAP) as a highly functional cosmetic material.

Active ingredients have been around in cosmetics for a long time but have they really resulted in active cosmetic products\ulcorner In order to achieve this, the right active needs to be delivered to the right location at the right concentration for the correct period of time. And the extent (and therefore the concentration) of this delivery depends on the formulation. From a rather theoretical approach based on the polarity of the active ingredient, the stratum corneum and the oil phase, the Relative Polarity Index was established that enables the selection of a suitable emollient for ensuring skin penetration of the active ingredient. Practical examples subsequently show the validity of this approach that demonstrates that one can regulate the delivery of an active molecule (and therefore the efficacy of a cosmetic formulation) by selection and control of the emollient system. Cosmetic formulations are generally quite complex mixtures and subsequent experiments using different emulsifier systems indicated that this component of a cosmetic formulation could also have an impact on steering the active ingredient to the right layer of the skin, although it is too early to be able to derive general rules from this.

Oxidation/reduction titrations are important quantitative procedures for many chemicals. Several widely used analytical methods for cosmetic ingredients are based on the redox reactions. In this article, we summarized basic theories of redox titration and applications. Determination of unsaturation properties based on iodine or bromine number, quantitation of hydrogen peroxide or peroxide materials in several cosmetic ingredients and measurement of titanium dioxide, widely used sunscreen agent, in cosmetics are discussed here.

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.

The important elements influencing on the quality of make-up cosmetics are not only the ingredients themselves but also the cosmetic tool that delivers the ingredients. But sensory analysis by a has been used on a number of occasion. Therefore it is not reliable to apply the data to other products and not easy to identify the elements influencing the qualities of cosmetics. So we Intend to understand the elements influencing the quality of cosmetics and prepare the foundation by introducing objective measurement method. In this study, we fix the loose powder and make new loose powder puff. So we can accomplish objective measurement.

Objectives : Cosmeceutical activities such as anti-oxidative and anti-aging effects of the Doinseunguitang and its composition, a traditional prescription, were evaluated. Methods : We performed MTT assay, melanin synthesis inhibition assay, DPPH free radical scavenging assay, SOD-like activity, xanthine oxidase inhibition assay, astringent activity assay, tyrosinase inhibition assay, elastase and collagenase inhibition assay. Results : The results were obtained as follows : DPPH free radical scavenging of water extract Doinseunguitang (DISG) and ethanol extract DISG was 60% and 50% at 1,000 ppm. Xanthine oxidase inhibition effect of ethanol extract showed more than 80% at 500 ppm. Tyrosinase inhibition and inhibition melanin synthesis activities were measured in 40% and 50% at 1,000 ppm and 100 ppm. Elastase and collagenase inhibition rate of ethanol extracts DISG 40% and 80% at 1,000 ppm. It was concluded that compositive ingredients (Persicae Seman, Glycyrrhizae Radix, Cinnamomi Ramulus, Rhei Rhizoma) influenced the most results. Conclusions : The results indicated that, ethanol extract which is superior in its anti-oxidative and anti-aging effects is useful to be applied in herbal cosmetic industry.

Recently, the number of customers who want natural cosmetics without petroleum originated cosmetic ingredients is increasing over the world, however, there are few natural cosmetics that claim functionality in the products. Because there are few functional cosmetic ingredients from nature and though so, it is very difficult to stabilize the final products manufactured by using those functional cosmetic ingredients in the long period. This study is on stabilization of oleanolic acid, insoluble anti-wrinkle cosmetic ingredients from nature, with hydrogenated lecithin in the solubilization product, aiming for developing a formulation of solubilization products which can be certified as organic cosmetics. In case of other synthetic solubilizers, they showed unstability at $45^{\circ}C$ within 2 ~ 3 days, however, for natural origin hydrogenated lecithin a stable product was made without particle size change during 4 weeks. The stability of oleanolic acid in the solubilization product was measured for 24 weeks at $25^{\circ}C$ and $40^{\circ}C$, both samples showed over 90 wt% value of the initial one, which can prove that oleanolic acid was stabilized in the product without any degradation. Also through clinical tests, the effect of moisturizing, anti-wrinkle, safety were confirmed.

Aloe is a popular and effective agent used to cosmetic ingredient. It could replace artificial pigment on make-up base product and it is highly probable that might be useful as ingredients of multi-functional color cosmetic. In this study, we made a makeup base containing aloe extract and tested the effectiveness, safety and stability. Contents of polyphenol and flavonoid from the aloe extract were measured. To determine the antimicrobial effect from the aloe we used the paper disc diffusion method. We assessed the safety of make-up base containing aloe to cultured macrophage RAW 264.7 cells by MTT assay. Polyphenol contents of aloe extract and flavonoid respectively were 48 mg/g and 10 mg/g, in the 10 % concentration aloe extract. In case of aloe make-up base, the clear zone against Stapylococcus epidermidis was 9~11 mm and Stapylococcus aureus was also 9~11 mm. Growth activity of macrophage RAW 264.7 cells was over 80% in all concentration of make-up base containing aloe and general make base product. In conclusion aloe extract may be able to substitute the synthetic pigments and considered to be uses for ingredients multi-functional color cosmetic's ingredient.

Mma-5 and Malva are extracts from a defined seaweed of the Rhodophyceae family and an annual or perenial plant, respectively. They have traditionally a significant stimulating properties such as protein synthesis, astringent, emollient, and et al.. In order to investigate the effect on wound healing, we studied for cell migration, cell attachment, and cell proliferation in vitro. The results of present study demonstrated that MMA-5 and Malva extract had the effect on wound healing, therefore we suggested that they could be effective materials to be applied to Cosmetic products.
