中文名称：表面活性剂 洗涤剂 阳离子活性物含量的测定 第2部分：低分子量（200-500）阳离子活性物

英文名称：Surface active agents — Detergents — Determination of cationic-active matter content — Part 2: Cationic-active matter of low molecular mass (between 200 and 500)

标准范围

This part of ISO 2871 specifies a method for the determination of low-molecular-mass cationic-activematerials such as monoamines, amine oxides, quaternary ammonium compounds and alkylpyridinium saltswhich have a main chain of 10 to 22 carbon atoms and not more than 6 other carbon atoms in the cation.The method is also suitable for other cationic-active materials.The method is applicable to solids or to aqueous solutions of the active material when the relative molecularmass of the cationic-active matter is known or when it has been previously determined if its content isexpressed as a percentage by mass. If more than one type of cationic-active material is present, an estimateof average relative molecular mass may be used.The method is not applicable if anionic and/or amphoteric surface active agents are present.
