Abstract

PURPOSE: To provide a cosmetic which contains bovine placenta extract and magnesium L-ascorbyl phosphate, thus shows excellent skin-whitening action, cell-activating action and humectant action with safety increased. CONSTITUTION: Placentas from healthy pregnant cows of third to fourth month is cleaned to removed blood or the like and made in slurry and subjected to extraction of only water-soluble components at a temperature lower then 5°C followed by centrifugation and germ-free filtration to prepare the water-soluble placenta extract. The extract is subjected to ultrafiltration or gel filtration to effect fractionation in the range from 900 to 1,000 ultramolecular weight and combine the fraction from which the components over the ultramolecular weight are removed with magnesium L-ascorbyl phosphate. The residue after the fraction of about 10,000 molecular weight is removed is free from sensitive substances and phsosphatases, but preserves cell-activating action, melanine- forming inhibitory action, skin-softening action and small creases- and roughened skin-improving action.
