Hydroxypropyl starch(HPS) leHydroxypropyl methyl cellulose(HPMC) ke li-polysaccharides tse peli tse sebelisoang hangata lits'ebetsong tse fapaneng tsa indasteri, ho kenyeletsoa meriana, lijo le kaho. Ho sa tsotellehe ho tšoana ha tsona, HPS le HPMC li na le liphapang tse fapaneng tsa 'mele le lik'hemik'hale tsa tsona, hammoho le mesebetsi ea tsona ea ts'ebetso. Sehloohong sena, re tla hlahloba phapang lipakeng tsa HPS le HPMC mabapi le sebopeho sa bona sa lik'hemik'hale, thepa le ts'ebeliso.

Sebopeho sa Lik'hemik'hale

HPS ke motsoako oa starch o fumanoang ka ho fetola lik'hemik'hale starch ea tlhaho ka lihlopha tsa hydroxypropyl. Lihlopha tsa hydroxypropyl li khomaretsoe ho lihlopha tsa hydroxyl holim'a molek'hule ea starch, e leng se hlahisang starch e fetotsoeng ka ho qhibiliha le botsitso bo ntlafetseng. HPMC, ka lehlakoreng le leng, ke motsoako oa cellulose o fumanoang ka ho fetola lik'hemik'hale selulose ka lihlopha tsa hydroxypropyl le methyl. Lihlopha tsa hydroxypropyl li hokahantsoe le lihlopha tsa hydroxyl ho molek'hule ea cellulose, ha lihlopha tsa methyl li hokahantsoe le likarolo tsa anhydroglucose.

Thepa

HPS le HPMC li na le litšobotsi tse ikhethang tsa 'mele le lik'hemik'hale tse li etsang hore li tšoanelehe bakeng sa lits'ebetso tse fapaneng. Lintho tsa HPS li kenyelletsa:

1. Solubility: HPS e qhibiliha ka metsing 'me e ka etsa litharollo tse hlakileng maemong a tlase.
2. Viscosity: HPS e na le viscosity e batlang e le tlase ha e bapisoa le HPMC le li-polysaccharides tse ling.
3. Botsitso: HPS e tsitsitse maemong a mangata a fapaneng a mocheso le maemo a pH mme e hanyetsana le li-enzyme le lintho tse ling tse senyang.
4. Gelation: HPS e ka etsa li-gel tse fetolehang ka mocheso maemong a phahameng, e leng se etsang hore e tšoanelehe bakeng sa lits'ebetso tse fapaneng tsa lijo le tsa meriana.

Thepa ea HPMC e kenyelletsa:

1. Solubility: HPMC e qhibiliha ka metsing 'me e etsa litharollo tse hlakileng maemong a tlase.
2. Viscosity: HPMC e na le viscosity e phahameng mme e ka etsa tharollo ea viscous leha e le maemong a tlase.
3. Botsitso: HPMC e tsitsitse maemong a mangata a fapaneng a mocheso le maemo a pH mme e hanyetsana le li-enzyme le lintho tse ling tse senyang.
4. Bokhoni ba ho etsa lifilimi: HPMC e ka etsa lifilimi tse tšesaane, tse tenyetsehang tse thusang lits'ebetsong tse fapaneng tsa meriana le tsa litlolo.

Lisebelisoa

HPS le HPMC li na le lits'ebetso tse fapaneng ka lebaka la thepa ea tsona e ikhethang. Lisebelisoa tsa HPS li kenyelletsa:

1. Lijo: HPS e sebelisoa ho matlafatsa le ho tsitsisa lijong tse fapa-fapaneng, tse kang lisoso, sopho le lirosa.
2. Pharmaceutical: HPS e sebelisoa e le setlamo le sebolaea matlapa le li-capsules le joalo ka koloi ea ho tsamaisa lithethefatsi.
3. Kaho: HPS e sebelisoa e le sekontiri le se tlamang lihlahisoa tse entsoeng ka samente, tse kang seretse le konkreite.

Lisebelisoa tsa HPMC li kenyelletsa:

1. Lijo: HPMC e sebelisoa e le sekontiri le se matlafatsang lihlahisoa tse fapaneng tsa lijo, joalo ka ice cream, yoghurt le lintho tse apehoang.
2. Pharmaceutical: HPMC e sebelisoa e le se tlamellang, se senyang, le se etsang filimi ka har'a matlapa le li-capsules le joalo ka koloi ea ho tsamaisa lithethefatsi.
3. Tlhokomelo ea Botho: HPMC e sebelisoa lihlahisoa tse fapaneng tsa tlhokomelo ea motho, joalo ka litlolo, li-shampoo, le litlolo, joalo ka setepi le se matlafatsang.
4. Kaho: HPMC e sebelisoa e le sekontiri le se tlamang lihlahisoa tse thehiloeng ho samente, joalo ka seretse le konkreite, hape e le sekontiri sa thepa ea moaho.

Qetello

Qetellong, HPS le HPMC ke li-polysaccharides tse peli tse sebelisoang haholo lits'ebetsong tse fapaneng tsa indasteri. HPS ke motsoako oa starch o nang le viscosity e batlang e le tlase, e ka khutlisetsoa morao ka mocheso, 'me e tsitsitse maemong a mangata a fapaneng a mocheso le maemo a pH. HPMC, ka lehlakoreng le leng, ke motsoako oa cellulose o nang le viscosity e phahameng, o ka etsa lifilimi tse tšesaane, tse tenyetsehang, hape o tsitsitse ka mefuta e mengata ea mocheso le pH. Phapang lipakeng tsa metsoako ena e 'meli e etsa hore e tšoanelehe bakeng sa likopo tse fapaneng liindastering tse fapaneng, ho kenyeletsoa lijo, meriana, tlhokomelo ea motho ka mong le kaho.
