General description
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。
Application
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。
Preparation Note
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。
