ISO/TR 18818:2017描述了一种通过气相色谱法快速采样和鉴定化妆品和化妆品原料中二乙醇胺（DEA）的筛选方法？质谱（GC-MS）。 本方法不适用于DEA相关成分的检测和/或量化。当使用该方法分析不熟悉的样本矩阵时，建议分析员确认矩阵中技术的适用性和灵活性。 在规定的条件下，该方法在DEA水平为1000 mg/kg（0.1%）时可可靠地进行定量。 然而，浓度较低（<；0,1%）或其他不寻常成分或特征的样品可能会出现困难（例如，峰拖尾），妨碍直接使用该方法。

ISO/TR 18818:2017 describes a screening method for rapid sampling and identifying of diethanolamine (DEA) in cosmetics and raw materials used in cosmetics by gas chromatography?mass spectroscopy (GC-MS). This method is not applicable to the detection and/or quantification of DEA-related ingredients. When this method is used to analyse unfamiliar sample matrices analysts are advised to confirm the applicability and flexibility of the techniques in their matrix. Under the conditions specified this method is reliable for quantification with DEA level at 1 000 mg/kg (0,1 %). However, samples with lower concentrations (<0,1 %) or otherwise unusual compositions or characteristics can present difficulties (such as, for example, peak tailing) that preclude the direct use of this method.
