Kaha metsoako ea lintho tse phelang e le lihlapolli tse futsanehileng tsa hydroxyethyl cellulose, metsoako ena ea tlhaho e ka sebelisoa ho lokisa motoho.

Hydroxyethyl cellulose hangata ke phofo e entsoeng le granular. Hafeela litaba tse latelang li hlokometsoe, ho bonolo ho sebetsana le ho qhibiliha ka metsing.
