4. Izicelo kuMayeza:
   • I-Excipient kwi-Tablets: I-HPMC isetyenziswa ngokubanzi njenge-excipient yamachiza, isebenza njenge-binder, i-disintegrant, kunye ne-film-coating material for tablets.
   • IiNkqubo zokuKhululwa eziLawulwayo: I-solubility kunye ne-film-forming properties ye-HPMC yenza ukuba ilungele ukuqulunqwa kweziyobisi ezilawulwayo.
   • Izisombululo ze-Ophthalmic: Kwi-ophthalmic formulations, i-HPMC isetyenziselwa ukuphucula i-viscosity kunye nexesha lokugcinwa kwamaconsi esweni.
5. Izicelo kwiZixhobo zoKwakha:
   • Udaka kunye neSement Additive: I-HPMC iphucula ukusebenza, ukugcinwa kwamanzi, kunye nokunamathela kodaka kunye nesamente kushishino lokwakha.
   • I-Tile Adhesives: Isetyenziswe kwi-adhesives ye-tile ukuphucula ukubambelela kunye nokulungelelanisa i-viscosity yomxube wokunamathela.
   • IiMveliso eziSekwe kwiGypsum: I-HPMC iqeshwe kwiimveliso ezisekwe kwigypsum ukulawula ukufunxwa kwamanzi kunye nokuphucula ukusebenza.
6. Usetyenziso kwiiMveliso zoKutya:
   • I-Agent etyebisayo: I-HPMC isebenza njenge-ejenti etyebisayo kwiimveliso ezahlukeneyo zokutya, inika ukuthungwa kunye nokuzinza.
   • I-Stabilizer: Isetyenziselwa ukuzinzisa kwiimveliso ezifana neesosi kunye neengubo zokuthintela ukuhlukana kwesigaba.
   • Ukutshintshwa kwamafutha: I-HPMC ingasetyenziswa njengokutshintshwa kwamafutha kwiindawo ezityebileyo ezinamafutha aphantsi okanye angenawo amafutha.
7. Usetyenziso kwiiMveliso zokuKhathalela umntu:
   • Izithambiso: I-HPMC ifumaneka kwizinto zokuthambisa ezifana neloshini, iikhrimu, kunye neshampu ngenxa yokujiya nokuzinza kwayo.
   • Uqulunqo lwezihloko: Kwimixube yezihloko, i-HPMC ingasetyenziselwa ukulawula ukukhutshwa kwezithako ezisebenzayo kunye nokuphucula ukuthungwa kwemveliso.
8. Iingqwalasela zoLawulo:
   • I-HPMC ngokuqhelekileyo ithathwa njengekhuselekile (GRAS) ukuba isetyenziswe ekutyeni nakwizicelo zamayeza.
   • Ukuthotyelwa kwemigangatho yolawulo kubalulekile ukuqinisekisa ukhuseleko kunye nomgangatho weemveliso eziqulethe i-HPMC.
