一般說明
该产品是一种中粘度羟甲基化纤维素(CMC);水中国2%溶液的粘稠时在25C时是400-800厘泊(cps)。粘度与浓度和温度有关。当温度上升,粘稠度下降。当浓度增大,粘稠度增加。
低,中,高粘度CMC都可用作悬浮剂。低粘度CMC通常用作“稀”水溶液。 中等粘度CMC可使溶液像糖浆一样粘稠。 高粘度CMC用于制备类似于乳膏或乳液的混合物。

應用
可使用不同粘度的可溶性羧甲基纤维素(CM-纤维素; CMC)作为粘度调节剂(增稠剂),以稳定乳液并作为油和其他碳结构(如纳米管)的化学分散剂。CMC用于开发生物结构产品,如生物膜、乳液和纳米颗粒药物递送系统。 羟甲基化纤维素,中粘度,可以用来使溶液有糖浆的稠度。
準備報告
该产品在水中可溶(20mg/ml)
将羟甲基化纤维素溶解的关键是仔细地将固体加入水中,这样使它能够分散均匀(充分湿润)。可能需要将固体分批添加至水中。 将水添加至干燥固体中会产生难以溶解的固体“团块”;因此必须将固体添加至水中。轻轻搅拌或间歇摇动;请勿使用磁力搅拌棒不断搅拌。无需高温,高温实际上可能减慢溶解过程。混合装置,如产生涡旋的叶轮型搅拌器,可将粉末卷入液体中,但是它可能会对粉末产生一些剪切作用。
