Abstract:
A production method of a cationized cellulose or a cationized hydroxyalkylcellulose, including step 1 for adding a cationizing agent to cellulose and mechanically decrystallizing the cellulose and step 2 for adding a basic compound to the mixture obtained in step 1 and mechanically decrystallizing the cellulose, or a production method of a cationized cellulose or a cationized hydroxyalkylcellulose, including a step 3 for adding a basic compound to cellulose and mechanically decrystallizing the cellulose and step 4 for adding a cationizing agent to the mixture obtained in step 3 and mechanically decrystallizing the cellulose. The cellulose and the cationizing agent are allowed to react with each other in step 2 or step 4.
