Summary:The present invention relates to a surface-modified retinoid-impregnated porous silica. More specifically, the present invention is characterized in that porous silica is impregnated with a polyethoxylated retinoid and then surface-treated with a silane-based compound to increase the impregnation efficiency of the retinoid and improve sustained release efficiency, and thus can be used as an active ingredient in functional cosmetics having improved stability and safety. La présente invention concerne une silice poreuse à surface modifiée imprégnée de rétinoïde. Plus particulièrement, la présente invention est caractérisée en ce que de la silice poreuse est imprégnée d'un rétinoïde polyéthoxylé puis traitée en surface par un composé à base de silane pour augmenter l'efficacité d'imprégnation du rétinoïde et améliorer l'efficacité de libération prolongée et ladite silice peut ainsi être utilisée en tant que principe actif dans des produits cosmétiques fonctionnels présentant une stabilité et une sécurité améliorées. 본 발명은 표면 개질된 레티노이드 담지 다공성 실리카에 관한 것으로, 보다 상세하게는, 본 발명은 폴리에톡실화된 형태의 레티노이드를 다공성 실리카에 담지한 후 실란계 화합물로 표면 처리함으로써 레티노이드의 담지 효율을 높이고, 서방성 방출 효율을 개선하여 안정성과 안전성이 개선된 기능성 화장품의 유효성분으로 활용할 수 있다.
