Abstract (en)
[origin: DE19941893A1] The invention relates to low-viscous cellulose ethers that flocculate in hot water and that have a high degree of purity and whiteness. The invention also relates to a method of producing the same by acidic-catalyzed hydrolytic depolymerization in the presence of an oxidation agent, as well as to the use thereof.
