稳定性和贮藏条件
室温下,在带有聚乙烯螺旋盖的琥珀色玻璃瓶中硬脂富马酸钠可以保存三年。
大容量包装的硬脂富马酸钠应存于密闭容器中,置阴凉干燥处。
配伍禁忌
有报道,硬脂富马酸钠不能与醋酸氯己定配伍。
安全性
硬脂富马酸钠被用于口服制剂中,通常被认为无毒无刺激性。
硬脂富马酸钠在大鼠和狗体内的代谢研究表明:大约80%被吸收,35%被快速代谢。吸收的部分被水解为硬脂醇和富马酸,硬脂醇进一步氧化成硬脂酸。在狗体内,没被吸收的硬脂富马酸钠24小时内以原型的形式由粪便排泄。
硬脂醇和硬脂酸是很多食品中天然成分,而富马酸是机体组织正常成分。WHO已经审定过硬脂酸酯和枸橼酸硬脂酯。枸橼酸硬脂酯的可接受日常摄入量为50mg/kg体重。没有必要确定硬脂酸酯和富马酸日摄入量。
有报道,富马酸二钠比NaCl的毒性稍强。
进一步的资料参见富马酸,硬脂酸和硬脂醇。
操作注意事项
遵守材料操作的环境和数量相应的常规注意事项。硬脂富马酸钠应在通风处操作,建议戴护眼镜。
法规
已列入GRAS。FDA准许作为调节和稳定剂直接加入下列供人食用的食品中:各种烘烤食品,面粉稠化食品,烘干马铃薯及处理过的谷物,用量可占食品重量0.2~1.0%。在英国许可用于口服制剂。FDA收载入《非活性组分指南》(口服胶囊剂和片剂)中。
注释
市售商品为硬脂富马酸钠的纯品,当不太纯的硬脂酸酯类润滑剂有化学配伍禁忌而不适用时,就显示出硬脂富马酸钠的价值。其疏水性比硬脂酸镁或硬脂酸弱,且对片剂溶解的滞后效应比硬脂酸镁小。
硬脂富马酸钠的EINECS号为203-743-0。
