초록
후코이단을 보습제 및 기능성화장품 소재로 사용하기 위한 후코이단 특성 및 그 효과에 대해 연구하였다. 후코이단은 미역 포자엽에서 추출하였다. 화장품 소재 시험으로는 보습력 측정, 항산화(DPPH assay, radical scavenging), 안전성(MTT assay)을 실시하였다. 후코이단의 보습력은 최고의 보습제 중의 하나인 히아루론산의 보습력보다 높았고, 분자량이 감소함에 따라 보습력이 약간 증가하였다. 후코이단은 높은 안전성과 항산화력을 보였다. 후코이단의 보습력 및 항알레르기 효과를 평가하기 위해 아토피 환자 46명에게 후코이단 크림을 6주간 적용하였다. 증상 정도를 나타내는 IGA 값이 3.04에서 2.15로 감소해 39.8%의 증상개선 효과가 있었다.
Properties of fucoidan used for functional cosmetics agents were studied. Fucoidan was extracted from Undaria pinnatifida sporophylls. To test possibility of fucoidan as a cosmetics material, water-holding property measurement, DPPH free radical scavenging assay and MTT assay were done. Water-holding property of fucoidan was higher than that of hyaruronic acid, which is known as the one of the best water-holding material. The water-holding strength of fucoidan slightly increase as molecular weight of fucoidan decrease. Fucoidan showed high stability from MTT assay and good anti-oxidation property from DPPH assay. To evaluate the effect of water-holding property and anti-alergy property of fucoidan on the atopic dermatitis(AD), 46 AD patients were treated with fucoidan cream. After 6 weeks treatment, Investigation Global Assessment(IGA) scores decreased from 3.04 to 2.15, that is fucoidan cream had a 39.8% benefit effect on atopic dermatitis.
