  1. ORYZA CERAMIDE All Natural - 100% Rice Derived Ceramide Excellent Skin Rejuvenator オリザ油化株式会社

  2. Rice (Oryza Sativa) • Rice (Oryza sativa) - widely grown and consumed grain in the Southeast Asia - rich in unique bioactive compounds - glycosphingolipids were extracted from rice bran & rice germ • Rice Ceramide: - brown extract from rice bran or rice germ - loaded with glycosphingolipids - similar to animal glycosphingolipids - plays an important roles in maintaining barrier function of skin

  27. The effect of Rice Glycosphingolipids on Skin Itchiness (Induction by Compound 48/80) No of Itchiness (% of control) [0.15%] group [0.3%] group [0.5%] group Experimental Method: 5-week old ICR mice divided into 4 groups were given free access to sample of rice glycosphingolipids. Compound 48/80 was applied to back of neck of mice 3-days later to induce itchiness. Mice were video 30 minutes later to view the reaction from compound 48/80 induction. Frequency of scratch were observed and counted.
