HPMC, ma ọ bụ Hydroxypropyl Methylcellulose, abụghị ihe na-emepụta ihe n'echiche siri ike nke okwu ahụ. Surfactants bụ ụmụ irighiri ihe nwere ma hydrophilic (mmiri na-ahụ n'anya) na hydrophobic (mmiri na-egbochi mmiri), a na-ejikwa ha belata esemokwu elu n'etiti mmiri mmiri abụọ na-enweghị atụ ma ọ bụ n'etiti mmiri mmiri na ihe siri ike. A na-ejikarị ihe ndị dị n'ahụ anya n'ọtụtụ ụlọ ọrụ dị iche iche, gụnyere ngwaahịa ihicha, ngwaahịa nlekọta onwe onye, ​​​​na ọgwụ ọgwụ, n'etiti ndị ọzọ.

N'aka nke ọzọ, HPMC bụ polymer nke dabeere na cellulose nke a na-eji na ngwa dị iche iche, gụnyere ọgwụ, nri, na ngwaahịa nlekọta onwe onye, ​​​​n'etiti ndị ọzọ. A na-emepụta HPMC site na cellulose na-agbanwe kemịkalụ, nke bụ polymer eke dị na osisi. Kpọmkwem, a na-emepụta HPMC site na iji otu methyl ma ọ bụ hydroxypropyl dochie ụfọdụ otu hydroxyl na cellulose. Ihe na-esi na polymer na-esi na ya pụta bụ mmiri na-agbaze ma nwee ike iji ya mee ihe dị ka onye na-ekpo ọkụ, ihe nkedo, emulsifier, na stabilizer, n'etiti ọrụ ndị ọzọ.

N'agbanyeghị na ọ bụghị surfactant, HPMC nwere ike igosipụta ihe ndị yiri surfactant na ngwa ụfọdụ. Dịka ọmụmaatụ, enwere ike iji HPMC mee ka emulsions guzosie ike, nke bụ ngwakọta nke mmiri mmiri abụọ na-enweghị ike ime, site n'ịme oyi akwa mkpuchi gburugburu ụmụ irighiri mmiri nke otu mmiri mmiri na mmiri ọzọ. Igwe oyi akwa a nwere ike igbochi ụmụ irighiri mmiri site na ikpokọta na ikewapụ na ngwakọta ndị ọzọ. N'ụzọ dị otú a, HPMC nwere ike ịrụ ọrụ dị ka emulsifier, nke bụ ụdị surfactant.

Tụkwasị na nke ahụ, a pụrụ iji HPMC mee ihe iji belata esemokwu elu nke mmiri, nke bụ ihe onwunwe nke surfactants. Dịka ọmụmaatụ, enwere ike iji HPMC dị ka ihe mkpuchi n'elu ebe siri ike iji mee ka ha nwekwuo hydrophilic, nke nwere ike ime ka ihe ọkụkụ ha dịkwuo elu. N'ime ngwa a, HPMC nwere ike ibelata nrụgide elu nke mmiri na-ekpuchi elu, nke nwere ike ime ka mmachi nke mmiri mmiri ma ọ bụ ihe siri ike dị n'elu.

N'ozuzu, mgbe HPMC abụghị a surfactant n'echiche siri ike nke okwu ahụ, ọ nwere ike igosi surfactant Njirimara na ụfọdụ ngwa. HPMC bụ polymer dị iche iche nwere ike iji mee ihe n'ọtụtụ ụlọ ọrụ, na ihe ndị pụrụ iche ya na-eme ka ọ bụrụ ihe bara uru n'ọtụtụ nhazi.
