Abstract
Abstract A bath preparations comprise a cyclodextrin clathrate compound of vitamin, saccharifying enzyme and other materials of baths. The vitamin may be selected from the group consisting of vitamin A, vitamin B, vitamin C, Vitamin D, vitamin E, vitamin F and vitamin P. The saccharifying enzyme may be mixed with the cyclodextrin clathrate compound of the vitamin or may be insulated from the cyclodextrin clathrate compound of the vitamin. Method for producing bath preparations comprises contacting vitamin with cyclodextrin to form a cyclodextrin clathrate compound of the vitamin and mixing the cyclodextrin clathrate compound of the vitamin with saccharifying enzyme and other raw materials of baths.
