Ib qho ntxiv, nws nce lub txee lub neej ntawm cov khoom lag luam thiab txo qhov kev xav tau rau cov tshuaj tiv thaiv. HPMC feem ntau siv hauv cov khoom noj muaj calorie tsawg vim tias nws tuaj yeem ua piv txwv ntawm cov rog uas tsis muaj cov calories qab zib ntxiv.
Sib nrug los ntawm nws txoj haujlwm tseem ceeb, HPMC muaj qee yam zoo hauv kev lag luam sib txawv. Nws muaj kev nyab xeeb rau tib neeg kev noj mov, yooj yim soluble hauv dej, thiab tsis muaj saj lossis tsw. Nws tseem yog biodegradable thiab ib puag ncig phooj ywg, ua rau nws muaj kev xaiv zoo rau ntau daim ntawv thov. Qhov tsawg toxicity thiab hypooalergenicity ntawm HPMC ua nws muaj kev nyab xeeb hauv ntau cov khoom lag luam, suav nrog cov tshuaj pleev ib ce, xab npum thiab xim pleev xim rau.
Hauv kev xaus, HPMC raws li cov lus qhia hauv cov hmoov daim foos yog qhov tseem ceeb tshaj plaws tseem ceeb hauv ntau qhov kev lag luam xws li kev tsim kho, chaw muag tshuaj thiab khoom noj. Nws cov khoom muaj ntau yam ua rau nws muaj cov khoom tseem ceeb hauv cov khoom lag luam tshiab thiab tsim cov khoom lag luam zoo, txhim kho qhov khoom zoo thiab ua tau zoo thiab ua tau zoo thiab ua tau zoo thiab ua tau zoo ntawm cov khoom kawg. Nws muaj kev nyab xeeb, muaj kev nyab xeeb thiab biodegrentity ua nws ib qho khoom siv zoo tagnrho rau ntau yam kev siv, ua rau muaj kev txhim kho ntawm cov khoom lag luam tshiab niaj hnub.
