一般描述

本品为高粘度羧甲基纤维素(CMC); 1%水溶液在25 oC下的粘度为1500-3000厘泊(cps)。粘度与浓度和温度有关。随着温度的增加,粘度降低。随着浓度的增加,粘度增加。低、中、高粘度的CMC都可用作悬浮剂。低粘度CMC通常用于“稀”水溶液中。 中粘度CMC用于制备看起来像糖浆的溶液。 高粘度CMC用于制备类似乳膏或乳液的混合物。

应用

具有不同粘度的可溶性羧甲基纤维素(CM-纤维素;CMC)可用作粘度改进剂(增稠剂)以稳定乳液,并可用作油和其他碳结构(如纳米管)的化学分散剂。CMC可用于开发例如生物膜、乳液和用于药物递送的纳米颗粒等生物结构。 高粘度的羧甲基纤维素可用于实现乳膏或乳液溶液的稠度。

制备说明

该产品可溶于水(10mg/ml)。溶解羧甲基纤维素的关键是将固体小心地加入水中,使其充分的分散(充分润湿)。该过程可能需要分批添加固体。 向干燥的固体中加水会产生难以溶解的固体“团块”;必须将固体加入水中。轻轻搅拌或间歇摇动;不要适用磁力搅拌棒不断搅拌。不需要在高温下溶解,事实上高温可能会减慢溶解过程。混合装置,例如产生涡流的叶轮型搅拌器,可帮助粉末混入液体中,但是其可能会产生一些剪切效应。注意,这种高粘度CMC通常以低于20mg/ml的浓度使用,但它在水中的溶解度可高达50mg/ml;需要加热以制备50mg/ml溶液。
