The galacturonic acid derivatives of formula: ##STR1## R1 being a linear or branched alkyl having 2 to 22 carbon atoms, R being: ##STR2## for which the carbon carrying the hydroxyl group is attached to the endocyclic oxygen atom. R2 being hydrogen, R1, an alkali metal atom, an alkaline-earth metal atom or a quaternary ammonium group of formula: ##STR3## in which R3 to R6 is each independently of the other hydrogen, an alkyl having 1 to 6 carbon atoms or a hydroxyalkyl having 1 to 6 carbon atoms, are surface-active agents.
公式为:##STR1## 中的半乳糖酸衍生物,其中R1是具有2到22个碳原子的线性或支链烷基,R为:##STR2## 其中携带羟基的碳原子连接到内环氧原子。R2为氢、R1、碱金属原子、碱土金属原子或公式为:##STR3## 中的季铵基团,其中R3至R6各自独立地为氢、具有1到6个碳原子的烷基或具有1到6个碳原子的羟基烷基,均为表面活性剂。
