Menene hydroxypropyl methylcellulose da aka yi daga?

Hydroxypropyl methylcellulose (HPMC) roba ne, polymer polymer mai narkewa da aka samu daga cellulose. Fari ne, mara wari, foda mara ɗanɗano wanda ake amfani da shi sosai azaman wakili mai kauri, emulsifier, tsohon fim, da daidaitawa a masana'antu da yawa, gami da magunguna, abinci, kayan kwalliya, da gini.

Ana yin HPMC ta hanyar mayar da martani ga cellulose tare da propylene oxide da methyl chloride. Cellulose shine polysaccharide wanda shine babban bangaren ganuwar tantanin halitta kuma shine mafi yawan kwayoyin halitta a duniya. Propylene oxide wani fili ne na kwayoyin halitta tare da dabarar sinadarai CH3CHCH2O. Methyl chloride iskar gas ce mara launi, mai ƙonewa tare da wari mai daɗi.

Halin cellulose tare da propylene oxide da methyl chloride yana haifar da samuwar ƙungiyoyin hydroxypropyl, waɗanda ke haɗe zuwa ƙwayoyin cellulose. Ana kiran wannan tsari da hydroxypropylation. Ƙungiyoyin hydroxypropyl suna haɓaka solubility na cellulose a cikin ruwa, yana sa ya fi sauƙi don amfani a aikace-aikace iri-iri.

Ana amfani da HPMC sosai a cikin masana'antar harhada magunguna azaman ɗaure, rarrabuwa, da wakili mai dakatarwa a cikin allunan da capsules. Hakanan ana amfani dashi azaman mai kauri da emulsifier a cikin creams da lotions, kuma azaman fim ɗin da ya gabata a cikin ruwan ido. A cikin masana'antar abinci, ana amfani da ita azaman mai kauri, stabilizer, da emulsifier a cikin miya, sutura, da sauran kayan abinci. A cikin masana'antar gine-gine, ana amfani da shi azaman mai ɗaure a cikin siminti da turmi, kuma azaman rufin ruwa don bango da benaye.

HPMC wani abu ne mai aminci kuma mara guba wanda Hukumar Abinci da Magunguna ta Amurka (FDA) ta amince don amfani da shi a cikin abinci, magunguna, da kayan kwalliya. Har ila yau, Ƙungiyar Tarayyar Turai (EU) ta amince da ita don amfani da shi a cikin abinci da magunguna.
