| titleOfInvention | Low molecular weight and oligomerization of water soluble hydroxypropyl chitosan |
| abstract | (Objective) Low molecular weight and oligomerization of water-soluble hydroxypropyl chitosan that does not cause water redness, coagulates in organic solvents, precipitates, penetrates into skin, absorbs well, and is not water-insoluble even when used as an animal therapeutic or added to cosmetics. To provide a way.n n n (Composition) Put chitosan and isopropanol in a beaker and alkali-slurry it, then add propylene oxide, warm it for a certain period of time, adjust the pH to mildly after stirring, filter it out, wash the residue with methanol, dry it at low temperature While obtaining oxypropyl chitosan powder,n n n After dissolving the hydroxypropyl chitosan powder in deionized water in a beaker, the cellulase or chitosanase was added and stirred while warming to 55 ~ 60 ℃, and then fermented by a certain time at about 80 ℃ to remove, precipitate It is a method of low molecular weight and oligomerization of water-soluble hydroxypropyl chitosan, characterized in that the obtained enzyme is filtered off and the filtrate is concentrated and freeze-dried. |
