HPMC waa cellulose suuf ah oo aad u saafi ah sida alaabta ceeriin, hoos xaaladaha alkaline by etherification gaar ah iyo diyaarinta.White ama budada cad.HPMC hoos u dhac ku ah content methoxide, korodhka dhibic gel, hoos u milmay biyaha iyo hoos u dhaqdhaqaaqa dusha.
HPMC waxay leedahay awood dhumuc, iska caabin milix ah, budada dambaska hoose, xasiloonida pH, haynta biyaha, xasiloonida cabbirka, samaynta filim heer sare ah, iyo tiro balaadhan oo ah iska caabin enzyme, kala firdhisan iyo adhesion.
HPMC, Hydroxypropyl Methylcellulose noocyada ether non-ionic cellulose, kuwaas oo ah budo ka mid ah caddaan ama midab cad, oo u shaqeeya sida dhumuc weyn, xidhe, filim-hore, surfactant, kolloid ilaalinta, saliid, emulsifier iyo ganaax iyo biyo haynta gargaarka. Intaa waxaa dheer, waxaa jira noocyo ka mid ah ethers cellulose waxay soo bandhigaan sifooyinka kuleyliyaha kulaylka, dheef-shiid kiimikaadka, caabbinta enzyme, urta iyo dhadhanka hooseeya, iyo xasilloonida PH.
Sababo la xiriira tirada badan ee guryaha, HPMC waxaa badanaa loo isticmaalaa in lagu beddelo waxyaabo kale oo badan oo leh feejignaan hoose, taasoo ka dhigaysa HPMC mid aad u hufan oo wax ku ool ah ku darsiga aagga xabagta, dhismaha, cuntooyinka, alaabta guriga, dawooyinka iyo iwm.
