Iyatọ laarin HPMC vs methylcellulose

HPMC (Hydroxypropyl methylcellulose) ati methylcellulose jẹ mejeeji ti o wọpọ ni ounjẹ, elegbogi, ati awọn ile-iṣẹ itọju ti ara ẹni gẹgẹbi awọn ohun ti o nipọn, awọn amuduro, awọn emulsifiers, ati awọn aṣoju abuda.Lakoko ti wọn pin diẹ ninu awọn ibajọra, awọn iyatọ diẹ wa laarin HPMC ati methylcellulose:

1. Ilana kemikali: Mejeeji HPMC ati methylcellulose jẹ yo lati cellulose, polysaccharide ti o nwaye nipa ti ara.HPMC jẹ cellulose ti a ṣe atunṣe, nibiti diẹ ninu awọn ẹgbẹ hydroxyl lori moleku cellulose ti rọpo pẹlu awọn ẹgbẹ hydroxypropyl.Methylcellulose tun jẹ cellulose ti a ṣe atunṣe, nibiti diẹ ninu awọn ẹgbẹ hydroxyl lori moleku cellulose ti rọpo pẹlu awọn ẹgbẹ methyl.
2. Solubility: HPMC jẹ diẹ tiotuka ninu omi ju methylcellulose, eyi ti o mu ki o rọrun lati tu ati lo ninu awọn agbekalẹ.
3. Viscosity: HPMC ni iki ti o ga ju methylcellulose, eyi ti o tumọ si pe o ni awọn ohun-ini ti o nipọn ti o dara julọ ati pe o le ṣẹda aitasera ti o nipọn ni awọn agbekalẹ.
4. Gelation: Methylcellulose ni agbara lati ṣẹda jeli nigbati o ba gbona ati lẹhinna tutu, lakoko ti HPMC ko ni ohun-ini yii.
5. Iye owo: HPMC ni gbogbogbo gbowolori diẹ sii ju methylcellulose.

Lapapọ, yiyan laarin HPMC ati methylcellulose yoo dale lori ohun elo kan pato ati awọn ohun-ini ti o fẹ ti agbekalẹ naa.HPMC le jẹ ayanfẹ fun solubility rẹ ati aitasera ti o nipọn, lakoko ti methylcellulose le jẹ ayanfẹ fun agbara rẹ lati ṣe awọn gels.
