Ho eketsoa ha cellulose ethers (HPMC/MHEC) ho seretse ho na le melemo e 'maloa ho kenyelletsa matla a ntlafatso a tlamo.Matla a phahameng a tlamahano a eketsa nako e telele ea ho tšoarella ha mohaho, ho qoba ho lokisoa ho theko e boima.
Li-cellulose ethers li boetse li fana ka ts'ebetso e betere ho seretse, ho etsa hore ho be bonolo ho aha le ho fokotsa nako e hlokahalang bakeng sa ts'ebetso e boima haholo.Ts'ebetso ena e ntlafetseng e thusa ho eketsa lebelo le katleho, kahoo e eketsa tlhahiso indastering ea kaho.
