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 purpose of this study is to investigate the skin type of $20{\sim}30’s$ women that use skin type test paper of cosmetic companies and usual using condition for the cosmetics. The result is as follows; The research target is $20{\sim}30’s$ woman in Seoul area, around capital city area and Geonra province, we surveyed the difference among the group, after dividing the groups with job, monthly income. As the result of research on the usual using cosmetics and cleansing products, $20{\sim}30’s$ woman mostly have toilet water, lotion and foam type cleansing product and use them. As the result of consciousness of skin type combination skin type is 46.1%, dry skin type is 23%, oily skin type is 15%, sensitive skin type is 9%, normal skin type is 7%. To compare results of skin type test paper of cosmetics companies with consciousness of skin type, result of skin type test paper of cosmetics companies was different consciousness of skin type. The result of skin type test paper of B company is same as consciousness of skin type is 31.2% and this result among cosmetics companies was appeared high ratio. Among the results from 3 companies, the rate that all result for 1 person's skin type are accord, is just 8%. 2 companies among them have matching rate of 42%. Most of all, each results of skin type test paper of cosmetics companies was appeared difference. This result show the problem of objectivity about skin type test paper of cosmetics companies that they using it.

최근 화장품을 사용하는 인구가 증가함에 따라 세안의 중요성도 강조되고 있다. 회전 브러시를 이용한 세안은 이전부터 산업계에서 적용되어 온 방법이나, 국내 문헌상 회전 브러시를 이용한 클렌징 기기의 세정효과에 대한 연구가 보고된 바가 없는 실정이다. 본 연구는 회전 브러시를 장착한 클렌징 기기인 PBRCF1201(Amorepacific Co., Korea)에 대한 세정력과 피부상태 개선효과에 대한 실험 결과를 보고한다. 총 20명의 환자가 참여하였으며, PBRCF1201를 사용하기 전 블랙헤드, 세정력(피부 밝기), 피부 각질, 모공, 유분함유량에 대해 측정을 하였고 시험제품을 1회 사용하게 한 후 동일한 항목을 측정하였다. 평가 대상 부위는 얼굴과 전박부를 대상으로 하였다. 그 결과 클렌징 젤을 단독으로 사용할 때보다 클렌징 젤과 클렌징 기기를 사용하였을 때 통계적으로 유의한 차이를 나타내며 더 좋은 세정력을 나타냈으며 피부 각질, 블랙헤드, 유분 함유량, 모공 개수 역시 감소하였다. 결론적으로 회전 브러시를 장착한 클렌징 기기는 피부에 손상이나 건조를 유발시키지 않는 효과적인 세안방법이라고 생각된다.

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.

소비자 욕구의 다양화와 관련 기술 등의 발달로 인하여 피부 미화, 청결 등의 단순한 효능만을 가지던 화장품이 이제는 주름개선, 미백 등의 실질적인 효능 효과를 가지는 제품으로 상품의 개발 방향이 변화되었다. 국내에서도 이러한 흐름에 발 맞추어 2000 년 식품의약품안전청 고시에 의해 화장품법이 제정되었고, 국내 화장품 산업이 발전할 수 있는 도약의 전기와 함께 본격적인 `기능성화장품'시대가 개막되었다. 2000 년 7 월 화장품 법 시행 이후 나름대로 정착되어가고 있는 기능성 화장품 제도가 변화하는 여성 소비자들에게 어떻게 이해되고 있는지를 라이프스타일 중심으로 파악해 봄으로써 라이프 스타일에 따른 기능성 화장품의 소비자 유형 분류에 대한 기초 정보 제공과 기능성 화장품 시장 세분화에 대한 마케팅 전략 수립의 기초 자료가 되리라 사료된다.
