Moisturizing cream prepared from lysate extract produced by fermentation of bacillus subtilis

The invention discloses a moisturizer prepared from a lysate extract produced by fermentation of bacillus subtilis. The hydroxydecyl ubiquinone is identified in Y-3FLE, and the yield of the hydroxydecyl ubiquinone is 0.45 mu g / g after the hydroxydecyl ubiquinone is cultured for 4 days, so that the quinone substances are identified in the Halophilic bacteria in the Yuncheng Salt Lake for the first time. The Y-3FLE is prepared by adopting absolute ethyl alcohol as a solvent, the oxidation resistance of the Y-3FLE is investigated through an in-vitro experiment, and a result shows that the Y-3FLE is relatively high in reducing capacity and relatively high in oxidation resistance. A human body closed patch test result shows that the Y-3FLE has no obvious irritation to human skin. The method is applied to the moisturizer, and human body efficacy evaluation is carried out through a multi-probe skin tester. Results show that the moisturizer added with 1% of Y-3FLE has multiple remarkable effects of moisturizing, repairing, nourishing and the like.
