硬脂酸鈉(sodium stearate)是一種有機化合物,化學式為C18H35NaO2,由硬脂酸(十八烷酸)與氫氧化鈉反應生成。它是白色粉末或蠟狀固體,可溶于熱水形成膠體溶液,具有表面活性和乳化作用。以下是其核心信息:
化學性質與結構
硬脂酸鈉屬于羧酸鹽,分子包含長鍊疏水烷基(C17H35)和親水羧酸根(-COO⁻)。這種兩親性結構使其成為典型的陰離子表面活性劑。
主要應用領域
安全性
根據美國食品藥品監督管理局(FDA)的評估,硬脂酸鈉在食品添加劑中被列為一般公認安全物質(GRAS),常用于抗結劑(參考鍊接:FDA食品添加劑數據庫)。日常接觸劑量下無顯著毒性,但高濃度粉塵可能刺激呼吸道,需佩戴防護設備(來源:化學品安全技術說明書)。
