The preparative technique and applied research of the extracts from tremella
Abstract: In this study, the preparative technique and applied research of the extracts from tremella were studied. By adjust the four influence factors: the time of the extract( from 2 hours to 10 hours), the pH of the extracting solution(from 4 to 10), the temperature of the extract (from 80 degrees Celsius to 100 degrees Celsius), and the ratio of material to solvent (from 1:40 to 1:120). By measuring the absorbance of the extracts from tremella, and contrasting with the canonical plotting, so that we can get the mass concentration of the extracts from tremella. According the mass concentration, the optimum synthesis conditions for the extracts from tremella is that the time of the extract is 4, the temperature of the extract is 100 degrees Celsius and the ratio of material to solvent is 1:80. After that I do the four factors, four levels orthogonal experiment and measure the absorbance of the extract from tremella, the optimal factors is that the time of the extract is 5, the temperature of the extract is 100 degrees Celsius and the ratio of material to solvent is 1:80. At last, by joining the rheolobic modifiers, hydrolyzed glycosaminoglycans and the soluble oil, lower the sticky feeling of the cosmetics. According to the experiment, joining the material with the bate adhesive efficiencyand fasting the rate of absorption can achieve the results.
