PRODUCTION OF RAW MATERIAL FOR EXTERNAL PREPARATION FOR SKIN AND EXTERNAL PREPARATION FOR SKIN COMPRISING THE SAME RAW MATERIAL AS ACTIVE INGREDIENT

摘要

PURPOSE: To obtain a raw material for an external preparation for skin having high safety and raising activity of skin by fermenting rice bran and soybean peptide with Bacillus subtilis and purifying. CONSTITUTION: Rice bran and soybean peptide obtained from a natural substance as a starting raw material is fermented with Bacillus subtilis (e.g. Bacillus natto). The fermented solution is purified by pressing and filtration to give the objective substance. Rice bran and soybean peptide are used in the ratio of 100:1 to 100:20. The prepared raw material for an external preparation for skin is used as an active ingredient and pharmaceutically manufactured into an external preparation for skin effective for preventing chapped skin, luster of skin and skin tension.
