Hydroxypyl methylcellose (hpmc): HPMC gabaɗaya yana da ƙarin bayanin martaba na danko mai mahimmanci idan aka kwatanta da MC. Maganin HPMC ya kuma rinjayi ta hanyar digiri na canzawa, amma ya kasance mai tsayayye a cikin babban kewayon yanayin zafi. Bugu da ƙari, za'a iya dacewa da HPMC don samun viscosities daban-daban, daga ƙananan zuwa High, gwargwadon aikace-aikacen da aka nufa.

4. Aikace-aikace

Ana amfani da MC da HPMC sosai a cikin magunguna, abinci, da masana'antar kwaskwarima, amma takamaiman kaddarorin kowane ya sa su dace da wasu aikace-aikace.

Kayan kwaskwarima: Ana amfani da MC a cikin kayan kwalliya don thicketing, emulsify, da kuma daidaita kaddarorin a cikin kayayyaki kamar lotions, shamfu, da cream.

Hydroxypyl methylcellose (hpmc):

Magunguna: An yi amfani da HPMC sosai azaman m da saki-mai sarrafawa a cikin tsarin kwamfutar hannu. Hakanan ana amfani dashi a cikin mafita ophthalmic a matsayin mai shafa da kuma a cikin tsarin bayarwa na gel da aka bayar.

Masana'antar abinci: Ana amfani da HPMC a cikin yin burodi mai ban sha'awa, kamar yadda shi mimics mai zane da kuma elarguity na gluten a kullu. Hakanan ana amfani dashi azaman mai tsinkaye da emulstifier a cikin masana'antun da aka sarrafa daban-daban.

Shiri: Ana amfani da HPMC azaman ƙari a cikin sumunti, filastar, da Tala. Yana inganta aiki, riƙewar ruwa, da kuma adhesion.

5. Sauran kaddarorin

Hygroscopicity: HPMC gabaɗaya shine ƙarin hygroscopic fiye da MC, wanda ya sa ya zama da amfani a aikace-aikacen inda ake buƙatar haɓaka mai riƙe danshi.

Kwanciyar hankali: MC nusar da ke nuna mafi kyawun kwanciyar hankali saboda kayan aikinta. HPMC, yayin da aka tsallake a cikin kewayon zafin jiki na zazzabi, bazai samar da tasirin gerarancin da ke da zafi ba kamar MC.
