1. Ọcha:
N'ezie, isi ihe na-ekpebi ogo hydroxypropyl methylcellulose enweghị ike ịbụ naanị ọcha. Ụfọdụ ndị na-emepụta ihe ga-agbakwunye ihe ndị na-acha ọcha na-emepụta ihe na usoro mmepụta ihe, na nke a, a pụghị ikpebi àgwà ahụ, ma ịdị ọcha nke hydroxypropyl methylcellulose dị elu dị mma n'ezie.
2. Mma:
Hydroxypropyl methylcellulose na-enwekarị ezigbo ntupu 80, ntupu 100 na ntupu 120. Ịdị mma nke ihe ndị ahụ dị oke mma, na solubility na njide mmiri dịkwa mma. Nke a bụ hydroxypropyl methylcellulose dị elu.
3. Nfefe ọkụ:
Tinye hydroxypropyl methylcellulose n'ime mmiri wee gbazee ya na mmiri ruo oge ụfọdụ iji lelee viscosity na nghọta. Mgbe e mechara gel ahụ, lelee nnyefe ọkụ ya, nke ka mma na-enyefe ọkụ, nke dị elu nke ihe na-adịghị edozi ahụ na ịdị ọcha.
4. Nnukwu ike ndọda:
