Abstract

The invention relates to a ceramide preparation pure dry powder which is white without peculiar smell and is made from galactosyl ceramide, phosphatide and cholesterol which are mixed uniformly. The weights of the galactosyl ceramide, the phosphatide and the cholesterol respectively take 60 percent to 70 percent, 20 percent to 25 percent and 10 percent to 15 percent in the total weight of the dry powder. A dry pasty ceramide preparation developed by East China Normal University and ethanol are used as raw material and extracting solution respectively. The ethanol is used for extracting ceramide from the dry pasty ceramide preparation twice, the extract is frozen and dried, and the dry powder is prepared. The dry powder is used as the raw material; a small quantity of 95 percent medical ethanol is added to be heated and dissolved and injected into hot stirred distilled water by an injector; and ceramide lipidosome emulsion is prepared. The dry powder is added into cosmetic; the addition is 0.01 percent to 0.1 percent of the weight of the cosmetic; the dry powder and the cosmetic are stirred uniformly; and the cosmetic with moisturizing function is prepared.

Description

technical field [0001] The invention relates to a pure dry powder of ceramide preparation and its preparation and application, belonging to the technical field of biochemistry. technical background [0002] Sphingolipids are important components of cell membranes and widely exist in animals and plants, especially in animal brain and nerve tissues. The parent structure of sphingolipids is ceramide, which is formed by linking one molecule of sphingosine and one molecule of long-chain fatty acid. [0003] In recent years, the results of skin research have shown that lipids that exist between skin keratinocytes are important substances for maintaining skin health. The main components are ceramide and its glycosyl derivatives, and the secondary components are cholesterol and cholesterol esters. . Ceramide and its glycosyl derivatives are important substances for protecting the skin. Their skin care functions in the stratum corneum of the epidermis mainly include: barrier effect...
