Process for producing low endotoxin chitosan |
| abstract |
The present invention relates to a process for producing a low endotoxin alkali chitosan, and also to a process for producing low endotoxin neutral chitosan, chitosan salt and chitosan derivatives, and to the products of such processes. The process comprises contacting chitosan with an alkali solution to form a mixture and leaving the mixture for at least about 12 hours. The low endotoxin alkali chitosan may be used in the manufacture of other useful chitosan based products. |
