[Testing of the composition of e-cigarette liquids - Manufacturer-declared vs. true contents in a selected series of products].

Abstract:

BACKGROUND:Electronic cigarettes are currently in common use. However, in Poland there is no specific legislation governing the sale of these products. At the same time, no information has been made public about the hazards e-cigarettes pose to the users and bystanders - passive smokers. The aim of the study was to determine the qualitative composition of the analyzed liquid, which is an essential element of regulating the distribution of such cigarettes. MATERIAL AND METHODS:Under this study the method for determining the composition of e-cigarette liquids was developed. This method employs gas chromatography with mass spectrometry (GC-MS). Levels of nicotine and flavoring components were determined in 50 e-liquid samples. The results were compared with the information provided by the manufacturer on the packaging. RESULTS:The applied method of qualitative determination helped to identify the main ingredients, such as nicotine and propylene glycol (PG). Propylene glycol was found to be present in all liquids, because it was used as the solvent for nicotine and flavors. There was a good agreement between the declared and the determined content of nicotine in the analyzed samples. The agreement was considerably poorer for the remaining e-liquid ingredients, mainly flavors. CONCLUSIONS:There was no agreement between the flavor substances specified by the manufacturer and aroma identified in the e-cigarette liquid, which may pose a risk to users of e-cigarettes, particularly those susceptible to allergies. Several unsaturated aliphatic alcohols and aldehydes found to be present in the liquids, unstable at elevated temperatures, may be more harmful to the smoker than the original compounds. Therefore, it is essential to implement in Poland the legal provisions regarding e-cigarettes. Med Pr 2016;67(2):239-253. WSTĘP:E-papierosy są obecnie powszechnie używane, a ich sprzedaż corocznie znacząco rośnie. Jednocześnie w Polsce brakuje szczegółowych przepisów prawnych regulujących sprzedaż tych wyrobów. Brakuje też informacji, jakie zagrożenia e-papierosy stwarzają dla użytkowników i osób postronnych – biernych palaczy. Celem badania było określenie składu jakościowego płynów do e-papierosów, które jest niezbędnym elementem działań regulujących dystrybucję takich papierosów. MATERIAŁ I METODY:W badaniu opracowano metodę oznaczania składu jakościowego płynów do e-papierosów i zastosowano chromatograf gazowy ze spektrometrem mas (gas chromatography with mass spectometry – GC-MS). Wykonano badania 50 próbek płynów różniących się zawartością nikotyny i składników smakowo-zapachowych. Wyniki badań skonfrontowano z informacjami zamieszczonymi przez producenta na opakowaniu produktu. WYNIKI:Zastosowana metoda oznaczania jakościowego pozwoliła zidentyfikować główne składniki płynów do e-papierosów, którymi są nikotyna i glikol propylenowy. Ten ostatni składnik występował we wszystkich płynach, ponieważ jest rozpuszczalnikiem głównego komponentu, którym jest nikotyna, i składników smakowo-zapachowych. W analizowanych próbkach płynu do e-papierosów stwierdzono zgodność zawartości nikotyny i glikolu propylenowego z informacją podaną przez producenta, natomiast informacje były niezgodne w przypadku substancji smakowo-zapachowych. WNIOSKI:Nieprawdziwe informacje dotyczące substancji smakowo-zapachowymi stosowanych przez producenta w płynie e-papierosów mogą stwarzać zagrożenie dla użytkowników e-papierosów, szczególnie osób ze skłonnością do alergii. Stwierdzona w badanych próbkach płynu obecność związków z grupy nienasyconych alkoholi alifatycznych i aldehydów, niestabilnych w podwyższonej temperaturze, może być niebezpieczna dla palącego – bardziej niż związki wyjściowe (np. akroleina). W związku z tym istotne jest wprowadzenie w Polsce regulacji prawnych dotyczących e-papierosów. Med. Pr. 2016;67(2):239–253.
