Low-masanya hydroxypropyl cellulose (L-HPC) shi ne wanda aka samu daga cellulose, wani nau'in polymer na halitta da ake samu a ganuwar tantanin halitta.L-HPC an gyaggyara don haɓaka solubility da sauran kaddarorin, yana mai da shi kayan aiki iri-iri tare da aikace-aikace da yawa a cikin masana'antar harhada magunguna, abinci, da kayan kwalliya.
Low-masanya hydroxypropylcellulose (L-HPC) ƙaramin maye gurbin cellulose ne wanda aka gyara da farko don inganta narkewa cikin ruwa da sauran kaushi.Cellulose shine polysaccharide madaidaiciya wanda ya ƙunshi raka'o'in glucose wanda ke da yawa a cikin yanayi kuma shine tsarin tsarin ganuwar tantanin halitta.L-HPC an haɗa shi ta hanyar canza cellulose ta hanyar sinadarai, yana gabatar da ƙungiyoyin hydroxypropyl don haɓaka solubility yayin kiyaye wasu kyawawan kaddarorin cellulose.
Tsarin sunadarai na ƙananan maye gurbin hydroxypropyl cellulose
Tsarin sinadarai na L-HPC ya ƙunshi kashin bayan cellulose da ƙungiyar hydroxypropyl da ke haɗe zuwa ƙungiyar hydroxyl (OH) na rukunin glucose.Matsayin maye gurbin (DS) yana nufin matsakaicin adadin ƙungiyoyin hydroxypropyl a kowace naúrar glucose a cikin sarkar cellulose.A cikin L-HPC, DS ana kiyaye shi da gangan don daidaita ingantacciyar solubility tare da kiyaye abubuwan da suka dace na cellulose.

Haɗin L-HPC ya haɗa da amsawar cellulose tare da propylene oxide a gaban alkaline mai kara kuzari.Wannan halayen yana haifar da gabatarwar ƙungiyoyin hydroxypropyl a cikin sarƙoƙi na cellulose.Kula da hankali na yanayin amsawa, gami da zafin jiki, lokacin amsawa, da maida hankali, yana da mahimmanci don cimma matakin da ake so na musanya.
Abubuwan da ke shafar narkewa
1. Digiri na canji (DS):
Solubility na L-HPC yana shafar DS.Yayin da DS ke ƙaruwa, hydrophilicity na ƙungiyar hydroxypropyl yana ƙara bayyanawa, ta haka yana inganta narkewa a cikin ruwa da abubuwan kaushi.
2. Nauyin kwayoyin halitta:
