COSMETIC COMPOSTION CONTAINING CITRON EXTRACT FERMENTATION SOLUBLES AND METHOD OF MANUFACTURING THE SAME

摘要

The present invention relates to a method to manufacture a cosmetic composition with whitening effect containing fermented citron extract and the cosmetic composition. The cosmetic composition contains the fermented citron extract obtained by the method comprising: cutting citrons into small pieces; naturally drying flesh, skins, and seeds of the citrons and then finely grinding using a grinder; adding a solvent like water 10 times the weight ratio of the dried citron powder and extracting the extract at 30-60°C for 12-24 hours; removing microorganisms in supernatant of the extract, which has been filtered with a filter cloth, using a 0.2 um filter; inoculating 1-10% of a culture fluid of Kazachstania unispora into the supernatant of the extract; and incubating at 20-25°C for 4-7 days as an active ingredient, thereby being able to obtain the fermented citron extract having a whitening effect similar to previously developed arbutin. By fermenting the citron extract, the effects of the fermentation product, which is depolymerized or not in the original extract, on skin beauty and whitening are enhanced; and a cosmetic composition containing the fermented citron extract, in which an active ingredient of citrons for skin beauty is depolymerized to easily be penetrated into the skin, can also be obtained.
