概述

本品为部分取代2-羟丙基醚纤维素,是非离子型纤维素醚,为碱化纤维素与环氧丙烷反应制得;按干燥品计,含羟丙氧基(一0CH2CHOHCH3)应为53.4%~80.5%。性状为白色或类白色的无定形或结晶性粉末。在水或丙二醇中极易溶解,在甲醇或乙醇中易溶,在丙酮或三氯甲烷中几乎不溶。

用途
羟丙纤维素广泛用于口服和局部用制剂。在口服制剂中,羟丙纤维索主要用于片剂的粘合剂、薄膜包衣材料和缓释制剂骨架材料。低黏度规格羟丙纤维素可作为湿法或干法制粒的粘合剂,或直接压片工艺的干粘合剂,用量一般为2-6%;还可以作为乙醇体系或水体系的包衣粉中的成膜性材料。高黏度规格的羟丙纤维素可用作缓控释制剂骨架材料,用量一般为15~35%。
在局部用制剂中,羟丙纤维素可在透皮贴剂或眼科制剂中使用。在食品和化妆品中,可作为乳化剂和稳定剂使用。

This product is partially substituted 2-hydroxypropyl ether cellulose, a non-ionic cellulose ether, which is prepared by the reaction of alkalized cellulose and propylene oxide; According to the dried product, the hydroxypropoxy group (0ch2chohch3) should be 53.4% - 80.5%. Amorphous or crystalline powder with white or off white properties. It is very soluble in water or propylene glycol, soluble in methanol or ethanol, and almost insoluble in acetone or chloroform.
purpose
Hydroxypropyl cellulose is widely used in oral and topical preparations. In oral preparations, HPF is mainly used as adhesive for tablets, film coating materials and skeleton materials for sustained-release preparations. Hydroxypropyl cellulose with low viscosity specification can be used as adhesive for wet or dry granulation, or dry adhesive for direct tablet pressing process, and the dosage is generally 2-6%; It can also be used as film-forming material in coating powder of ethanol system or water system. HPC with high viscosity specification can be used as the skeleton material of slow-release and controlled-release preparations, and the dosage is generally 15~35%.
In topical preparations, HPC can be used in transdermal patches or ophthalmic preparations. In food and cosmetics, it can be used as emulsifier and stabilizer.
