This document describes a screening method for rapid sampling and identifying of diethanolamine (DEA) in cosmetics and raw materials used in cosmetics by gas chromatography \u2013 mass spectroscopy (GC-MS).<\/p>\n

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.<\/p>\n

Under the conditions specified this method is reliable for quantification with DEA level at 1 000 mg\/kg (0,1 %).<\/p>\n

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.<\/p>\n
