This study investigated lead adsorption by carboxylated alginic acid and its application in cleansing cosmetics. Carboxylated alginic acid showed the highest lead adsorptivity after oxidation in a 4-6 mM hydrogen peroxide solution at $20-30^{\circ}C$ for 30-40 min. Carboxylated alginic acid adsorbed $648.1{\pm}2.8-653.0{\pm}2.9$ mg/g of lead dry mass at pH 4-6. Carboxylated alginic acid modified by hydrogen peroxide and potassium permanganate adsorbed $651.3{\pm}3.8$ and $639.9{\pm}4.0$ mg/g of lead dry mass, respectively. Carboxylated alginic acid showed higher lead adsorptivity after modification by hydrogen peroxide than by potassium permanganate, with an increase of ~30% compared with raw alginic acid. To access the potential application of carboxylated alginic acid in cleansing cosmetics, we investigated the lead adsorptivity, conditions of the cosmetics procedure, and cytotoxicity of various concentrations of cleansing cosmetics added to 5% carboxylated alginic acid. The ideal cosmetic concentrations combined with 5% carboxylated alginic acid were 70% for peeling gel, 20% for massage cream, 20% for foam cleansing and 40% for cleansing cream. There was no cytotoxicity in cleansing cosmetics combined with 5% carboxylated alginic acid.

Today, men's appearance is an important part of the global fashion industry, including Korea, with such fashion concepts as the Metrosexual and Ubersexual. Domestic and overseas beauty and cosmetics related organizations are using this phenomenon for marketing and researching to improve the function of cosmetics. The purpose of this study was to investigate the effect of Prunus persica L. Batsch leaf extract on the skin condition after clinical application to male subjects with oily skin to determine the possibility of functional cosmetics utilizing this extract. The cleansing bars were prepared by the MP method and the cleansing packs were prepared using natural ingredients. After 8 weeks of application, moisture, oil, erythema, melanin, pH, elasticity and tactile sensation were measured using MPA5. The results showed that there was a statistically significant difference in T-zone moisture and T-zone oil after using the natural cleansing bar, but there was no significant difference between the two groups for other items. However, the statistically significant changes were found in the individual skin condition change items of the subjects in each group, and it was judged that the two kinds of formulations could be used at the same time to have a higher skin improvement effect. Thus, Prunus persica L. Batsch leaf extract demonstrates potential to be used as a functional cosmetics item.

The stability of cream containing lotus leaf extract (LLE) was evaluated. Stability pH and viscosity were measured at 3 different temperatures ($25^{\circ}C$, $45^{\circ}C$ and $65^{\circ}C$), and at room temperature under the sun light at 2 day intervals during 12 days. The cleansing cream and foam cleansing containing the extract did not show a significant pH change at the different temperatures. However, the pH of the cleansing cream and foam cleansing containing LLE slightly decreased at $25^{\circ}C$. They showed a high stability at temperature conditions ($45^{\circ}C$ and $65^{\circ}C$) and under the sun light condition. The cleansing cream and foam cleansing containing LLE did not show a significant viscosity change at $25^{\circ}C$, but had a tendency of decrease at $45^{\circ}C$ and $65^{\circ}C$. There was no significant offflavor and discoloration as well as physical changes such as creaming and cohesion at $25-65^{\circ}C$ and under the sun light condition. And this LLE could be used as a stable functional cosmetic material.

The purpose of this study is to develop a method to evaluate solubility parameter interactions of cosmetic ingredients in formulations. This experimentation relates to the fabrication of new multi-layer cleansing oil which can remove make-up products such as lipstick, foundation, mascara, eye shadow, etc., and also can wash away dirt and sebum from the skin just in one stage process. Solubility parameter and specific gravity of various cosmetic ingredients are measured to explain the cleanliness of interface, detergency of make-up cosmetics on the skin surface. The results suggest that it is possible for cosmetic chemists to use solubility parameter of cosmetic materials for fabrication of new formulation of 3-layer cleansing oil.

The main goal of this study was to find an optimal surfactant mixture composition for the development of the best performing cleansing products. Three different surfactants including sodium cocoyl alaninate (SCoA), cocamidopropyl betaine (CPB), and decyl glucoside (DG) were selected, which showed excellent properties in detergency, foaming height, and contamination rate through preliminary experiments. The experiments by simplex centroid design matrix for surfactant mixtures were performed, and the regression analysis was conducted with the experimental data. Surface response model equations, which is statistically significant (p < 0.05), were obtained. The optimal composition of the surfactant mixture was also determined as SCoA (0.22), CPB (0.78), and DG(0.00) from simultaneous optimization of three response variables.

Recently, the importance of cleansing is emphasized according to increasing use of cosmetics. Even though many cleansing devices with a rotating brush are commercially available, there are no reports about cleansing devices with rotating brushes in Korean literature. In the present study, we evaluated the efficacy of cleansing device with a rotating brush which was named PBRCF1201 (Amorepacific Co., Korea). 20 volunteers were enrolled in this study. Before and after use of PBRCF1201, we measured the number of black head, skin brightness, desquamation index, sebum, and the number of pores on the face and forearm. Cleansing by cleansing device with a rotating brush was shown to cleanse better than manual cleansing. In addition, the number of black heads, skin brightness, desquamation index, sebum and the number of pore were also improved after cleansing. Therefore, the cleansing device with a rotating brush appears to be an effective cleansing method without causing injury or dryness.

Cosmetic mask is one of the traditional cosmetic product and is used to keep skin healthy and beautiful through moisturizing effect, cleansing effect and acceleration effect on microcirculation. There are several types of cosmetic mask such as peel-off type, tissue-off type, wash-off type and cotton sheet type immersed in cosmetic water. It is important for cosmetic formulators to develop an adequate type of cosmetic mask that meets the needs of the target consumers because each type of cosmetic mask has benefits and problems in its usage and efficacy. Polyvinyl alcohol (PVA) is widely used as an active ingredient of peel-off type cosmetic mask and the physical property of the PVA film changes with the usage of other ingredients. We studied the change of physical properties of the film containing PVA by formulating peel-off type cosmetic mask with the variation of humectants. Methylguceth-20 and glycereth-26 reduce the interaction between skin surface and PVA film without serious weakening of tensile strength and they can alleviate irritation. Glycerin, urea and betaine help PVA film soften and they also have excellent efficacy as humectants.

Cosmetics have had only simple efficacy such as cleansing, beautification, and so on. The latest development tendency for cosmetics turned to make goods that is effective and efficacious for whitening, anti-wrinkle, etc., due to various wants of consumers, development of relative technical, etc. According to this stream, Korea Cosmetics Law has been enacted by the Notification of the Korea Food and Drug Administration in 2000. The establishment of Korea Cosmetics industry and opened regular 'Cosmeceuticals Time'. Since the Korea Cosmetics Law took effect on July 2000, the cosmeceuticals system has settled down according to its lights. This research studied how women consumers were understanding the cosmeceuticals system focused on their life style. This study is considered to offer a basic information about consumer's type and to be a groundwork data for working out a marketing strategy about the subdivision of cosmeceuticals market.
