Ethyl cellulose 是纖維素的衍生物。Ethyl cellulose 是一種無(wú)毒、可生物降解的聚合物，在食品和制藥領(lǐng)域具有獨(dú)特的油凝膠形成、活性成分輸送和成膜能力等特性。Ethyl cellulose 可用作藥用輔料，如包衣劑、調(diào)味劑、片劑填充劑等。藥用輔料或藥用助劑，是指制藥過(guò)程中使用的除藥物成分以外的其他化學(xué)物質(zhì)。藥用輔料一般是指藥物制劑中的非活性成分，能提高藥物制劑的穩(wěn)定性、溶解性和加工性。藥用輔料還會(huì)影響共同給藥藥物的吸收、分布、代謝和消除 (ADME) 過(guò)程。

生物活性

Ethyl cellulose is a derivative of cellulose. Ethyl cellulose serves as a non-toxic and biodegradable polymer, with unique properties such as oleogel formation, delivery of active component, and film-forming ability in the food and pharmaceutical sectors. Ethyl cellulose can be used as an excipient, such as coating agent, flavoring agent, tablet filler. Pharmaceutical excipients, or pharmaceutical auxiliaries, refer to other chemical substances used in the pharmaceutical process other than pharmaceutical ingredients. Pharmaceutical excipients generally refer to inactive ingredients in pharmaceutical preparations, which can improve the stability, solubility and processability of pharmaceutical preparations. Pharmaceutical excipients also affect the absorption, distribution, metabolism, and elimination (ADME) processes of co-administered drugs[1][2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
