Scope

Scope: This document specifies a high-performance liquid chromatography method for determining the residual content of acrylamide in polyquaternium-7, polyquaternium-33, polyquaternium-39, and polyquaternium-53 products. This document is applicable to the determination of acrylamide residues in polyquaternium-7, polyquaternium-33, polyquaternium-39, and polyquaternium-53 products. Main technical content: After the polyquaternium sample is extracted with a mixed solvent of methanol, isopropanol, and saturated sodium chloride, the supernatant is filtered through a 0.45 μm microporous membrane and determined by high-performance liquid chromatography-ultraviolet detection. The retention time is used for qualitative analysis, and the external standard peak area method is used for quantitative analysis.
