Hydroxypropyl Methylcellulose
HydroxypropylMEthylcellulose (HPMC) cyangwa hypromelloseni inkomokos ya Methyl selile ethers. Nicyera cyangwa kitari cyera fibrous cyangwa granularselile etherifu. Ubu ni selile ethers hamwe nibikorwa byiza kwisi, guhuza umubyimba, guhagarika, gutatanya, kwigana no gutuza. Hydroxypropyl methyl selulose (HPMC) ni uburozi, byoroshye gukoresha, kandi byoroshye gushonga mumazi. Ni polyanion mugisubizo cyamazi kandi ifite imiterere yihariye yumubiri. Imikorere yihariye ni nk'inzogera:
