    • PROBLEM TO BE SOLVED: To provide a method of producing a moisturizing cosmetic material by utilizing a natural material having high safety.SOLUTION: A moisturizing cosmetic material is produced by heat treatment of an extract from thalluses or rhizoids of tangle, preferably a hot water extract, using high-pressure closed vessel, and producing pyrrolidone carboxylic acid and/or salt thereof with glutamic acid and/or salt thereof in the extract. By using the high-pressure closed vessel, the extract from tangle is effectively heat-treated in a short time, and pyrrolidone carboxylic acid can be produced by cyclization of glutamic acid and/or salt thereof. Since the obtained pyrrolidone carboxylic acid and/or salt thereof has moisturizing ability and excellent moisturizing ability through synergistic effect with amino acids except glutamic acid, the obtained pyrrolidone carboxylic acid can be utilized for the production of a cosmetic as a moisturizing cosmetic material. By combination with other moisturizing agent, moisturizing ability can also be improved.
    • 要解决的问题:提供一种通过利用具有高安全性的天然材料制备保湿化妆品材料的方法。溶液:通过热处理来自沙棘或根茎的提取物,优选热水提取物来制备保湿化妆品 使用高压密闭容器,并在提取物中与谷氨酸和/或其盐产生吡咯烷酮羧酸和/或其盐。 通过使用高压密闭容器,短时间内有效地对缠结的提取物进行热处理,可以通过谷氨酸和/或其盐的环化来制备吡咯烷酮羧酸。 由于得到的吡咯烷酮羧酸和/或其盐具有保湿能力和通过与除了谷氨酸以外的氨基酸的协同效应的优异的保湿能力,所得到的吡咯烷酮羧酸可用于生产作为保湿化妆品的化妆品。 通过与其他保湿剂的组合,还可以提高保湿能力。
