过去制剂上常用的亲液胶,大多是亚刺伯胶、西黄著胶之类的天然产物.但是此类物质有易腐败、每批成品规格不一致等缺点,所以近年来逐渐为羧基甲基纤维素(Sodium carboxymethyl cellulose,简称 CMC)、甲基纤维素(Methyl cell cellulore,简称 MC)等纤维素衍生物所代替。 In the past the commonly used on the preparation of lyophilic plastic, mostly Acanthopanax seborrhoea, West yellow plastic and the like natural products.But such materials are perishable, each batch of product specifications inconsistencies and other shortcomings, so in recent years gradually carboxymethyl Cellulose (Sodium carboxymethyl cellulose, referred to as CMC), methyl cellulose (Methyl cell cellulore, referred to as MC) and other cellulose derivatives replaced.
