DEFINITION

Classification: 106/172.1

Cellulose ether or salt thereof:

(under subclass 163.01) Compositions wherein the cellulosic material is a compound having the general formula ROR4, wherein RO- is the cellulose residue moiety and R4 is an ether forming radical.

(1) Note. Cellulose ether is made by etherifying the hydroxyl groups of cellulose.
