본 연구는 서울·경기 지역의 화장품을 사용하고 있는 18세부터 50대까지 남녀 317명을 대상으로 소비자 특성에 따른 화장품 품질(안전성, 안정성, 기능성, 사용성) 인식과 만족도의 차이를 분석하였고 부작용 경험에 따른 화장품 품질인식이 만족도에 미치는 영향을 분석하였다. 화장품 품질 요인 중 사용성에는 만족하고 있었으나 안전성, 안정성, 기능성 인식은 낮게 나타나 전반적인 품질 개선이 필요하였고 특히 남성과 40대의 화장품 품질 인식과 만족도가 낮게 나타나 이를 위한 맞춤형 솔루션이 필요하였다. 화장품 부작용을 경험한 경우와 안 한 경우 모두 사용성과 기능성의 순서로 만족도에 유의한 양(+)의 영향을 미쳐 사용성과 기능성 인식의 제고가 만족도를 높이는 주요 요인으로 나타났다. 제품의 품질을 개선하고 소비자 인식에 긍정적 영향을 주는 요소들을 보완하는 것이 품질 인식과 만족도 향상에 큰 도움을 줄 것으로 생각된다.

최근 전 세계적으로 석유 유래 합성 화장품 원료의 사용을 배제한 천연 화장품을 찾는 고객들이 계속적으로 증가하고 있지만 이러한 천연 화장품 중에서도 기능성을 소구하는 제품은 거의 없는 상황이다. 이는 천연 유래 원료중에서 기능성이 검증된 원료가 거의 없을 뿐 아니라, 그러한 천연 기능성 원료들이 있다고 하더라도 그것들을 천연 원료만으로 안정한 제형을 유지하기가 매우 힘들기 때문이다. 본 연구는 난용성 천연 주름 기능성 물질인 올레아놀릭산을 천연 유래 수첨 레시틴을 이용하여 안정하게 가용화시키는 것에 관한 것이며, 유기농 화장품 인증이 가능한 가용화 제형의 처방을 개발하는 것을 목표로 하였다. 다른 합성 가용화제를 사용할 경우 $45^{\circ}C$에서 2 ~ 3일 내에 올레아놀릭산의 석출이 관찰되었지만, 천연 유래 수첨 레시틴을 이용한 제형에서는 4주 동안 입자 크기의 큰 변화 없이 안정하게 유지되었다. 제형 내 올레아놀릭산의 함량은 $25^{\circ}C$ 및 $40^{\circ}C$에서 보관중인 샘플을 대상으로 24주간 측정하였는데, 두 온도에서 모두 90 % 이상을 보여주어 올레아놀릭산이 제형 내 분해 없이 안정하게 유지되는 것을 확인하였다. 또한 보습력 및 주름 개선 등의 임상시험을 통해 제품의 피부 효능과 안전성을 확인하였다.

Background: We investigated the antioxidant, anti-wrinkles, whitening, and moisturizing properties and amounts of phenolic compounds of ethanol extracts from flowers of 10 resource plants from Namwon and Mt. Jiri., Korea. Methods and Results: We measured antioxidant efficacy based on the total polyphenol, and total flavonoid content, and the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. We evaluated the inhibitory effect on melanin synthesis and tyrosinase activity for the whitening effect. Furthermore, we analyzed the elastase and matrix metalloproteinase-1 (MMP-1) inhibition activity for anti-wrinkle capacity. To evaluate the moisturizing effect, we examined hyaluronan synthase (HAS) mRNA expression. In addition, the 19 phenolic compounds were detected using high performace liquid chromatography (HPLC). Among the 10 flowers, the antioxidant effect was high in the order of Rosa multiflora, Nelumbo nucifera, and Elsholtzia splendens. Whitening effect was high in the order of N. nucifera, R. multiflora, and Dendranthema zawadskii. As for the anti-wrinkle property, N. nucifera was the most effective followed by R. multiflora. Taraxacum coreanum was the best for moisturizing effect, followed by D. zawadskii, and E. splendens. Seven phenolic compounds were detected in the extracts of the 10 flowers. Conclusions: Overall, the extracts of five flowers extracts showed strong potential as antioxidant, whitening, anti-wrinkle, and moisturizing functional cosmetic agents.

A new and unique class of nonionic surfactants was synthesized by reacting biological a-tocopherol with ethylene oxide for functional cosmetics. The structures were confirmed by Hl-UMR, FT-lR, TLC and elemental analysis. POV and conjugated diene value study for EPO showed POE(n)TE had antioxidative effect similar to tocopheryl acetate Protective effect on cell membrane in photohemolysis of POE(5)TE, POE(10)TE and POE(18)TE were slightly lower than tocopherol but higher than nonoxynol-12, and POE(10)TE had UV absorption power comparable with tocopherol and homosalate. Biological activity of the hydrophobic group of the new surfactants make them unique and different from those of conventional nonionic surfactants Systematic safety evaluations of POE(n)TEs on the skin and eye proved that they are as safe as tocopherol. The results of physicochemical study showed POE(10)TE had the lowest CMC value, POE(18)TE had the maximum surface tension reduction and the highest foam volume and POE(n)TEs had various HLB values by the degree of ethoxylation. The test resul Is of technological and practical applications of these surfactants for cosmetics showed some POE(n)TEs were superior to conventional surfactants. POE(5)TE in W/O emulsions, POE(10)TE and POE(12)TE in O/W emulsions, POE(12)TE in dispersions, POE(18)TE in solubilizations and POE(50)TE in gelations were shown to be excellent which was considered due to the structural characteristic and formation of liquid crystals of POE(n)TEs. By the development and applications of these excel lent multi-functional surfactants, innovative functional cosmetics were successfully formulated.

Red pepper (Capsicum annuum L.) is one of the most consumed vegetable worldwide. In this study, we tried to suggest the possibility of Cheongyang pepper as a functional cosmetic material by identifying the physiological activity, especially antioxidant and whitening effects of Cheongyang pepper through bibliometric analysis and experimental studies. A bibliometric analysis was performed through co-word analysis of 8,892 papers retrieved from SCOPUS. 4 research fields were obtained by cluster mapping from VOSviewer software, among which we noted the antioxidant activity of extracts from Capsicum annum L.. Phenol as a useful ingredient of Cheongyang pepper was analyzed using HPLC (high-performance liquid chromatography). Antioxidant and whitening effects were evaluated by measuring DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity, hydrogen peroxide scavenging activity, and tyrosinase inhibitory activity. Cheongyang pepper extract showed contents of 0.106 ± 0.01 and 0.105 ± 0.02 mg/g, respectively, in the order of gallic acid and protocatechuic acid. The extract exhibited 56.95% DPPH scavenging activity and 43.97% hydrogen peroxide scavenging activity at a concentration of 1,000 ㎍/ml. In addition, 1,000 ㎍/ml of the extract inhibited tyrosinase activity by 52.44% and 42.61%, respectively in a whitening efficacy test using L-tyrosine and L-DOPA (L-3,4- dihydroxyphenylalanine) as substrates. These results suggest that Cheongyang pepper extract and its active ingredients have antioxidant and whitening effects, and the possibility of future development as a whitening functional cosmetic material.
