Porous natural antiseptic porous which collects functional ingredients other than the oak tree extract using ultra-low temperature vacuum extraction system

摘要

The present invention relates to a hwangchil tree extract microcapsule containing a biodegradable polymer and a cosmetic composition for skin whitening containing the same, more specifically, to standardize so that the content of the curarinon in the hwangchil tree extract is included within a certain range, and when applied to the human body It relates to hwangchil tree extract that has excellent whitening effect and can be used for whitening cosmetics. The present invention having the above object is characterized in that the hwangchil tree extract-containing microcapsules in which the hwangchil tree extract is collected in a biodegradable polymer. At this time, the hwangchil tree extract is characterized in that it contains 0.001 to 50% by weight of curarinon as an indicator material. In addition, the biodegradable polymer forming the wall material of the hwangchil tree extract-containing microcapsules of the present invention is characterized in that it is polylactic acid, polymethyl methacrylate and polycaprolactone. At this time, the weight ratio of polylactic acid, polymethyl methacrylate, and polycaprolactone is characterized by being 7-8:2-3: 1-2.
