1. Solubality
Nkwelite nke Kimacell®hpmc bụ otu n'ime ihe ndị dị mkpa anụ ahụ na kemịkal. Enwere ike ịgbasa ya na mmiri iji mepụta ngwọta colloidal. A ga-enwekarị njikọ chiri anya na ogo molecular ya na ogo nke nhichapụ hydropyyl na methyl. Ohaneze, hpmc ya na oke molecular na-agbadakwu, ebe Hpmc nwere oke molecular na-agbada nwayọ. Na ihe okirikiri, HPMC anaghị etolite ihe owuwu siri ike ma gosipụta ụdị polymer ụdị polymer. Na mgbakwunye, HPMC nwekwara ezigbo sonyere ụfọdụ sonvic dị iche iche (dịka mmanya na Ketones), nke na-eme ka ọ bụrụ na ọ na-ejikarị ya ebe ụfọdụ.
2. Njirimara viscosis
Mpsancing na mmiri nwere ike imepụta ihe nzacha nke ihe nlele dị iche iche, na ihe ndị dị ka molecular ibu, ntinye uche na ọnọdụ okpomọkụ nke Hpmc. Dị ka ịta nke HPMC na-abawanye, viscosity nke ihe ngwọta na-abawanye nke ukwuu, na viscosis nke ihe ngwọta guzobere dị iche iche.

Omume ya na-enwe mmetụta nke ọma na ogo molecular ya, ụdị na ntinye uche nke ndị hiwere. N'okpuru ọnọdụ dabara adaba, enwere ike iji HPMC mee ihe dị ka RPMC, GLLLIGET ma ọ bụ emulsifier, nke na-eme ya n'ọtụtụ ebe na nri, ọgwụ, ihe ịchọ mma na ubi ndị ọzọ.
7. Arụ ọrụ elu
HPMC nwere ụfọdụ ọrụ dị elu n'ihi na o nwere hydrophilic na hydrophobic otu. N'okpuru ọnọdụ ụfọdụ, Kimacell®hpMC nwere ike belata esemokwu dị elu nke mmiri mmiri ahụ wee jiri ya.
