Abstract:
PURPOSE: A cosmetic composition for hair containing Paeonia lactiflora-brewed water having resveratrol is provided to prevent scalp aging and cell damage. CONSTITUTION: A cosmetic composition for scalp or hair contains 0.01-10.0 weight% of Paeonia lactiflora-brewed water. The Paeonia lactiflora-brewed water is extracted by adding Paeonia lactiflora to soluble composition containing water and infusing active ingredients of Paeonia lactiflora at low temperature. The composition additionally contains extracts of Opunitia ficus-indica var. saboten, Glycyrrhiza uralensis, or cacao seed. The composition is used in the form of hair tonic, hair essence, hair serum, scalp treatment, hair treatment, hair conditioner, hair shampoo or hair lotion.
Abstract:
A composition comprising an extract of Magnolia Obovata bark is provided to inhibit melanogenesis by inhibiting the activity of c-kit protein expressed in melanocyte effectively, thereby showing excellent whitening effect. A composition for inhibiting c-kit protein activity comprises 0.0001-10 wt.% of an extract of Magnolia Obovata bark as an effective ingredient, wherein the extract controls function of melanocyte by inhibiting signalling of cells in a melanocyte participated by a C-kit protein.
Abstract:
A lipid-based nano-carrier is provided to increase the whitening effect of an extract of Mori Cotex Radicis by encapsulating an extract of Mori Cortex Radicis in the lipid-based nano-carrier in which cholesteryl hemisuccinate is introduced, thereby effectively inhibiting the melanogenesis without side effects. The lipid-based nano-carrier is characterized in that it is in the form of a liposome dispersion or a nano-emulsion in which cholesteryl hemisuccinate encapsulating an extract of Mori Cortex Radicis or a salt thereof is introduced. Regarding the total weight of the total liposome dispersion or the nano-emulsion, the content of the lipid is 0.001-20 wt.% and the content of the extract is 0.001-30 wt.%. The skin whitening composition comprises the nano-carrier.
