硬脂酸钠(sodium stearate)是一种有机化合物,化学式为C18H35NaO2,由硬脂酸(十八烷酸)与氢氧化钠反应生成。它是白色粉末或蜡状固体,可溶于热水形成胶体溶液,具有表面活性和乳化作用。以下是其核心信息:
化学性质与结构
硬脂酸钠属于羧酸盐,分子包含长链疏水烷基(C17H35)和亲水羧酸根(-COO⁻)。这种两亲性结构使其成为典型的阴离子表面活性剂。
主要应用领域
安全性
根据美国食品药品监督管理局(FDA)的评估,硬脂酸钠在食品添加剂中被列为一般公认安全物质(GRAS),常用于抗结剂(参考链接:FDA食品添加剂数据库)。日常接触剂量下无显著毒性,但高浓度粉尘可能刺激呼吸道,需佩戴防护设备(来源:化学品安全技术说明书)。
