Sodium carboxymethyl cellulose (Viscosity:800-1200 mPa.s) 是羧甲基纤维素的钠盐,常用作黏稠剂,糊料和阻隔剂。
生物活性 | Sodium carboxymethyl cellulose (Viscosity:800-1200 mPa.s) is the sodium salt of cellulose arboxymethyl and frequently used as viscous agent, paste and barrier agent. |
体内研究 (In Vivo) | Protocal for preparing 0.5% CMC-Na Solution Measure 0.5g of dry CMC-Na and dissolved in 100 ml ddH2O/0.9% Saline (0.9 g NaCl in 100 ml ddH2O) to make a clear solution. Under the condition of stirring and heating (50-65℃), adding CMC-Na slowly to ddH2O/0.9% Saline helps to accelerate dissolution.
Note 1.You must ensure that your CMC-Na solution does not exist solid-liquid separation phenomenon. The solution is in a uniform and transparent state has no particles in it. 2.Completely dissolution of CMC-Na may requires 4 hours or more longer.
In a pharmacological test, CMC-Na (oral;5% in water; 1 year) is well tolerated in rats[2]. In an acute oral toxicity study in female mice, LD50of CMC-Na for female mice is 14 g/kg body weight of mice, equivalent to 9.8 g/kg body weight of rat, categorized as practically non-toxic according to Loomis criteria (LD505-15g/kg body weight of rat)[3].
