Cosmetics — Analytical method — Detection and quantitative determination of Diethanolamine (DEA) by GC/MS
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 (

Kozmetika - Analizne metode - Detekcija in kvantitativno določevanje dietanolamina (DEA) s plinsko kromatografijo z masno spektrometrijo (GC/MS)
Ta dokument opisuje presejalno metodo za hitro vzorčenje in prepoznavanje dietanolamina (DEA) v kozmetičnih izdelkih ter surovinah, ki se uporabljajo v kozmetiki, s plinsko kromatografijo – masno spektroskopijo (GC-MS).
Ta metoda se ne uporablja za detekcijo in/ali kvantitativno določevanje sestavin, povezanih z dietanolaminom. Pri uporabi te metode za analizo neznanih vzorčnih matric se analitikom priporoča, da potrdijo uporabnost in prilagodljivost tehnik v svoji matrici.
Ta metoda je pod opredeljenimi pogoji zanesljiva za kvantitativno določevanje z ravnjo dietanolamina 1000 mg/kg (0,1 %).
Vendar vzorci z nižjimi koncentracijami (<0,1 %) ali kako drugače nenavadne sestave ali lastnosti lahko pomenijo težave (kot je na primer razvlečenost vrhov), ki preprečujejo neposredno uporabo te metode.

Introduction
Diethanolamine (DEA) has been restricted for use in cosmetics and personal care products in a
number of jurisdictions due to its potential health risk since residual levels of DEA might react with
other specific ingredients to form the extremely potent carcinogen nitrosodiethanolamine (NDELA).
Therefore, a harmonized method for the screening of DEA in cosmetic raw materials is considered
important.
Numerous methods for the trace analysis of alkanolamines including DEA in different sample
[1] [2] [3]
matrices have been developed and published . Among the methods available for the analysis
of alkanolamines, techniques using gas chromatography (GC) or liquid chromatography (LC) with
[4] [5]
a variety of detector systems have received the most attention . More recent procedures, mass
spectrometry (MS) detection in combination with chromatography separation is used to determine
[6] [7]
analyte content in aqueous solutions with minimal requirements for extraction and cleanup.
In some cases, derivatization of alkanolamines has also been used to improve the chromatographic
[8] [9]
separations and detection .
This document describes a rapid and simple method suitable for simultaneously qualitative and
quantitative screening of cosmetics and cosmetic raw materials containing residue of above 0,1 %
diethanolamine (DEA).
